One lesson, studied three ways — hands-free audio, a flashcard deck, and a quiz — with a single spaced-repetition schedule behind all of them. Learn a phrase on the cards and your audio stops drilling it; forget it months later and it comes back in whichever mode you happen to open.
Everything below is built and working today. Anything still in progress is at the bottom of the page, clearly marked.
Every lesson is the same set of phrases seen from three angles. Switch between them whenever you like — your progress is shared, not restarted.
A segmented switcher sits on every lesson screen, so you can move from listening to drilling to testing without losing your place or your progress.
Each lesson opens on a written home page: an overview, the key phrases, teaching sections and tips, and a full two-column reference table of every phrase with its translation.
Generate a written walkthrough of a lesson — the concepts, the grammar notes, the tips behind its phrases. Reading a guide someone already generated is free, and the curated courses ship with theirs already written.
Opening the app drops you back into the course you were last working on, scrolled to the lesson you left, in the mode you were using.
The part you use with your hands on a steering wheel. Every lesson is one continuous track, chaptered by phrase, and you control how it's read to you.
A tappable waveform, a running time readout, a “Phrase 7 of 40” counter, and skip buttons that jump a whole phrase rather than a blind fifteen seconds. The current line highlights and scrolls itself into view as the audio moves.
The full phrase list sits under the player in the order you hear it. Tap a line and the audio seeks straight there.
0.75× through 2×, without the voices going chipmunky. The web remembers a speed per lesson, so a hard one can sit at 0.75× while a familiar one stays at 1.5×.
Space or K plays and pauses, arrows nudge five seconds, Shift+arrows skip a whole phrase.
Navigating doesn't stop playback — a compact player stays in the header with the title, phrase counter and controls, and tapping it returns you to the lesson.
When a lesson ends the next one starts on its own, so a curriculum plays like a podcast feed on a commute. You get a few seconds to cancel the jump if you'd rather stay put.
Per curriculum, decide whether playback stops, loops the curriculum until you know it, or rolls into the next one.
Six neural voices are free and unmetered and will speak any lesson language. Nine studio voices — including three soft-spoken readers made for night lessons — are Premium and metered against voice credits.
Reorder the steps — phrase, translation, slow repeat — by dragging, set each step's speed and voice, insert silent pauses, and set the gaps between steps and between phrases. Preset chips give you a starting point in one tap.
Instead of a fixed gap, the silence after a phrase can stretch to 1×, 1.25× or 1.5× the length of the phrase itself — so a long sentence gets a long gap and a single word doesn't.
Start from a ready-made listening pattern rather than building one: one-read capstone, native-only instructional, reverse drill with the meaning first, story one-shot, and multi-voice drills with music.
A walking piano chord at each phrase boundary, stepping through a progression you pick — jazz ii–V–I, diatonic, chromatic, circle of fifths or pop — with your own fade and pause timing, and a preview before you save.
One tap reverses the lesson so you hear the meaning first and have to produce the phrase — recall practice instead of listen-and-repeat. Tap again to flip back.
Re-cut the recording with the phrases in a fresh random order, so you're recognising the language rather than memorising the running order.
Cut something you already know from the recording while keeping it in your cards and quizzes. A panel lists everything you've trimmed, each with a Put back button.
Give a single line its own treatment — extra repeats, a slower pass, a different voice, a longer pause — without touching the rest of the lesson.
Tune the playback of any published lesson for yourself — order, speeds, voices, pauses, trims — without changing it for anyone else, and revert to the original whenever you like.
Type a phrase and its translation and it's spoken in the lesson's own voices. On a course you didn't write, the addition is private to you and joins your flashcard deck for that lesson.
Reordering, flipping, shuffling and trimming re-cut the audio from clips that were already recorded, so they're quick and cost no voice credits. Only genuinely new text needs a new recording — and if a change would spend credits, you're told first and offered a free alternative.
Some lessons open with a produced two-host conversation that sets up what you're about to drill. It plays as its own titled chapter, level-matched to the rest of the lesson, and never turns up as a flashcard or a quiz question.
A course can carry a parallel listening track — two hosts, in your own language, on the food, places and customs of the countries that speak what you're learning. It's never locked, never gated, and there's nothing on it to master or review.
A real deck, not a slideshow — with an editor for the card faces and a print file at the end of it.
A 3D card you tap or press Space to flip, with a language flag on each side. Each card plays its audio as it arrives, with a Replay pill and a one-tap mute.
Rate each card Forgot, Hard, Medium or Easy — and every button tells you when that card comes back (“in 10 min”, “in 4 days”) before you press it. Keys 1–4 do the same without the mouse.
Swipe the card instead of tapping. You choose which rating goes with which direction, a short capsule confirms what you just did, and there's an Undo right there if you flicked the wrong way.
Rate straight from the prompt side for cards you already know cold. Off by default — without it, a front-side swipe nudges you to see the answer first.
Retire a card you know cold in one press. It counts as an Easy answer and then drops out of your cards, quiz and audio — with an Undo, and a restore later from the Trimmed list.
Mis-tapped Forgot on something you actually knew? Undo puts the card's schedule back exactly as it was and shows it again.
One bar fills as you work through the deck; a second stacks this session's ratings by colour, so you can see the shape of the session and not just the count.
A panel lists everything that isn't in today's deck and why — resting on your schedule with a live countdown, trimmed from the audio, or retired — each with a Put back where it makes sense.
Open a lesson whose cards are all resting and you get a plain explanation and the next return date, not a fake “0 got” summary.
Start a deck answer-side-first, shuffle it, run it again from card one without losing your ratings, skip to the results, or open the phrase list and jump the deck to a specific card.
A drag-and-drop editor for the front and back of each card: move the text and image, add your own, set size, colour, alignment and bold, snap to centre, undo and redo. What you design is what shows in the app and what prints. On someone else's deck you design your own private copy — theirs is untouched.
Attach an image to any phrase so the card and quiz show a visual instead of text. On a course you didn't make, the picture is yours alone — and you can hide the author's picture for yourself.
Turn any deck into a PDF sized for real 5×3" cards — one card per page, fronts and backs interleaved so a duplex printer lines each pair up on one sheet. Text and shapes are true vector art, so small type stays crisp.
Four question types, and one of them listens to you speak.
See the meaning, pick the phrase from four options, with a speaker on each so you can hear it before you commit. Keys 1–4 answer and the correct phrase plays back afterwards.
Tap the mic, say the phrase, and get a 0–100 pronunciation score with accuracy, fluency and completeness broken out, plus what was actually heard. The phrase stays hidden until you ask for a hint, so you have to produce it from memory.
A loop built for driving: the prompt is read to you, the mic opens on its own, it stops when you stop talking, scores you, and moves on. If it doesn't catch you it quietly retries before showing the mic.
Type the missing words back into a phrase. Grading forgives capitals, accents and stray punctuation, so “ano” is accepted for “año”.
For phrases with a picture, parts of the image are masked; press space to reveal them one at a time and mark yourself right or wrong on each. Good for anatomy, maps and diagrams.
Tap individual words to turn them into cloze blanks, and drag rectangles over a picture to create the masks the Occlusion quiz reveals.
You don't press a rating in the Speak quiz — your pronunciation score picks it. 80%+ counts as Easy, 60–79% Medium, 40–59% Hard, and below that Forgot.
A panel shows exactly how each quiz type turns your answer into a review rating. Everyone can read it; Premium can change the thresholds — whether a miss counts as Forgot or Hard, whether a correct answer marks a card Easy or retires it.
Phrases you've drilled to the top of the ladder drop out automatically and come back the moment they're due again. There is no pool to manage.
Test-prep lessons run a different quiz: the wrong answers are written deliberately rather than borrowed from other cards, and each question comes with a written explanation of why.
One schedule behind all three modes, one place to work it down — Mastery Central, on every course page — and an unusual amount of honesty about what its numbers mean.
Get a phrase right and the gap before you see it again stretches — minutes, a day, days, weeks, months. Get it wrong and it collapses back to minutes and starts climbing again. Being late costs you nothing.
Phrases you've got solid drop out of your lesson audio while they're resting and slide back in once they're due. The app asks first and lists exactly which phrases are moving, with their text, before you accept.
Clear your due backlog as flashcards, as a multiple-choice quiz, by speaking, or as a passive audio playlist for the car. The audio review is a real stitched lesson with a scrubber, chapters and speed control.
One session walks every card due across every lesson in a subject, overdue first, with a live count badge so you know when something's waiting.
A big backlog is never an all-or-nothing wall — a review serves twenty, then offers “Keep going” or “Take a break”.
Each course page carries a pulse panel: how solid the course is right now, how much review debt has built up, how many phrases are waiting, and one button that starts a review scoped to that course. The number beside the button is exactly what pressing it gives you — never a count of things you would have to go hunting for.
Every phrase you have answered comes back through Mastery Central, and it joins the moment it is due — nothing has to graduate first, so a card you rated Forgot ten minutes ago waits there beside one you last saw six weeks ago. The only ones that never return are the ones you tested out of.
If enough phrases from earlier lessons are sitting due, starting brand-new ones in that course pauses until you review some down. Only phrases you had genuinely learned and then let lapse count toward that, so a lesson you have just worked through can never wall you for studying it. Lessons you've already touched stay open, nothing you finished ever re-locks, and listening is never blocked.
Every lesson tile carries two readings that mean different things: a ring for how many phrases are solid right now, which drains as cards come back due, and a bar plus a permanent “Completed” stamp for how much of the lesson you've worked through, which doesn't.
A “?” beside any lesson opens a page that works both meters out phrase by phrase — what's solid, what came back due, what's still learning, what you haven't started — with one plain sentence saying where you stand and what to do next.
A schedule page explains the rule, then shows your own queue grouped by return date — Ready now, Later today, Tomorrow, This week, This month, Further out — with a search box and a strip summarising the whole distribution.
Every resting phrase carries a thin bar filling toward its next review, labelled “Back in 14d”, “Back in 2h”, “Due now”, updating as you watch.
Adjust how soon a forgotten card returns, how much a Hard answer grows an interval, how fast intervals build, and how big an Easy jump is — each as a plain-language preset rather than a raw number. Changes apply on your very next rating.
In curated courses each part opens as you finish the one before it. Once you've touched something it stays open for good — coming back weeks later, or old cards falling due, never takes it away. Courses you create or save are always fully open.
Tap a locked part and you get a short quiz drawn from the material you'd be skipping. Get it right and it unlocks — and you choose whether those phrases stay in rotation or are retired as too easy.
Listening time by week, year and lifetime, quiz totals and accuracy, average answer time, your day streak, and twelve-week activity charts.
Start fresh on one lesson, a curriculum, a course, or everything — either resetting just the review schedule so the cards come round again, or erasing your progress there entirely. The page spells out exactly what stays either way.
Four ways into a new course, from a full coaching conversation down to pasting a spreadsheet.
One place to build, with four ways to start — talk to a Coach, fill in a quick form, describe a scenario, or type your own phrases — and you can switch between them at any time.
A coach interviews you about what you want, your level and your timeline, then proposes a numbered sequence of lessons with a reason for each. Tell it what to change before you approve, and the first lesson starts building immediately.
A short form — language, goal, level, time available — that skips the back-and-forth and hands you a finished course plan in one shot.
Describe a situation (“ordering breakfast at an Italian café”), pick how many phrases you want, and get a lesson written and voiced. Free on every account.
A spreadsheet-style grid where you type your own pairs, or paste a table straight out of Excel and watch it fill down and right. Swap the columns in one click, drag and delete a range, and mark any row as narration so it plays in the audio but never becomes a card.
Fill in one side of each row and have the other translated for you, in either direction, never overwriting anything you already typed.
Pick from flag chips or the full searchable list — and if what you want isn't there, type it and it's accepted.
Only the first lesson is written up front. Every later one shows a Generate button on its tile, so you build it when you get there instead of waiting for the whole course.
Watch which stage a lesson is in — writing the script, synthesizing the voices, assembling the audio — with a real percentage and notes like “8 of 24 voice clips done”.
Brief two hosts on a subject, get a free AI draft in the house style, then edit it as a chat-bubble conversation: rewrite any line, insert a beat between two lines, swap who says it, drag to reorder. An AI assist can redraft a single line. Nothing costs anything until you press Produce — and a sticky bar shows exactly what that will cost first.
Tick a box and the hosts pull their examples straight from the phrases you're about to study, weaving the target language into the banter so the meaning lands naturally.
Write one standing instruction for a course — “always include the vosotros forms”, “write for a high-school-age learner” — and every future script and line rewrite in it follows.
Fix a translation or reword a phrase. On your own lesson it changes the lesson; on someone else's it's saved as your private wording, with a revert to the original.
Spot a typo or a better translation in one of the delivered courses and you can send your wording in for review — accepted fixes are re-recorded for everyone.
Drag phrases into the order you want them taught, or remove one entirely. Reordering costs nothing — only changed text is re-recorded.
Once a lesson sounds right, push that exact setup onto every other lesson in the course in one step, with a preview telling you how many will change and which are being skipped.
Add an exam as a subject — SAT, ACT, GRE, GMAT, LSAT, MCAT, TOEFL, NCLEX, Bar, CPA and more — and the Studio switches to exam wording throughout. Lessons come back as real practice items you can answer hands-free: the question read aloud, a thinking pause, then the answer, with plausible wrong choices and a written explanation waiting in the quiz.
Phrases you type or paste are checked before any audio is made, with a clear reason back if something is rejected — and nothing is charged against your allowance for a flagged submission.
Subjects, then courses, then a scrolling rail of lessons — with the state of every one of them visible at a glance.
Everything you study is grouped into subjects — Languages, Test Prep, Reading, Math, Science and Humanities — with a tile for each and a catalog to add more.
Each subject tile shows its flag inside a ring tracking your next CEFR level, with a level badge and a red count of cards waiting.
Up to three next-step buttons — drill what's due, continue where you left off, browse your courses — over a progress dashboard laying out the whole A0 → C2 ladder with your position marked.
Every course card shows a ring, lessons done, cards mastered, minutes of audio, how many are due now, when you last studied, and a small bar chart of your mastery lesson by lesson.
A course opens as one long side-scrolling row of lesson tiles across all its curricula, with a banner naming whichever curriculum you've scrolled to, its goal, its total length, and arrows to jump a whole curriculum at a time.
Inside one course, the curated content, the curricula you built, and the ones you saved from Community each get their own labelled rail, so you always know whose content you're looking at.
Each tile's corner glyph tells you what that lesson is doing — ready, playing, queued, still generating, failed, or locked, each with its own plain-English explanation on hover or focus. A graduation cap marks a lesson you've fully retired.
Open a public course from Community and just start working through it, and it shows up in your library with your real progress. You don't have to remember to press Save first.
Short in-app tips introduce the scroll arrows, the curriculum stepper, the “?” explainer, the review card and the Test in button — each cleared by actually doing the thing, and all of them dismissible at once from your account.
On a course page, one tile bounces to show you exactly which lesson to open next.
Publish what you build, and pick up what other people have.
A Community tab lists courses other people have published, filtered by default to the subjects you study. Search by topic, sort by newest or most played, and widen the feed with subject chips.
Flip your own course from Private to Public and every curriculum in it becomes available to other learners. Making it private again pulls them all back.
Bookmark a public course and it lands in your library under Community. Unsaving removes it without touching their original.
Turn on the same step-by-step unlocking the curated courses use, so learners who pick your course up work through it in the order you designed. It never locks anyone out of work they've already started.
Flip your own course into a student's-eye view — locks applied, editing hidden — and wipe your own progress on it so you can walk it through clean.
Publishing under a username credits you on the course card; the app nudges you to pick one rather than shipping as “anonymous”.
Free is a real product, not a trial. Premium removes the caps and unlocks the studio-grade tooling.
The entire delivered library, all three study modes, the full spaced-repetition schedule and its four ratings, multiple-choice and cloze quizzes, six narrator voices, card images, the print-ready PDF, Community, and one personalized lesson generation a month.
Unlimited generations, longer lessons, the studio voice cast with 3,000 voice credits included every cycle, the AI Coach, pronunciation scoring, the Podcast Designer, AI lesson guides, the cadence and schedule tuning, and unlimited audio rebuilds. Checkout is handled by Stripe and discount codes work.
Studio voices are metered per character. Another 25,000 characters is $5 as a one-time purchase, and credits stack on what you already have. A gauge shows what's left and roughly how many lessons that buys.
Your plan page shows your generation allowance with a countdown to the reset, your monthly audio-rebuild allowance (rebuilds that reuse an existing mix don't count), and your image storage as a bar.
A button opens Stripe's own portal to change the card, pull invoices, or cancel — and cancelling leaves Premium active through the period you already paid for.
Email and password, Google, or Sign in with Apple, with a password reset by email. If you signed up with Google or Apple you can add a password later as a backup way in.
Pick a public username and upload a picture — big phone photos are shrunk for you, and there's a generated avatar if you never set one.
Tell the app which language you speak and new lessons translate into it. Existing lessons keep the language they were built with.
The mode you last used, your swipe setting, your grading rules and which tips you've seen are saved to your account, not the browser.
Redo onboarding to wipe your content and walk the setup again, or delete your account, lessons, audio and progress permanently — typing your email to confirm. The privacy policy and terms are readable without an account.
Immersful runs an MCP server, so you can build courses by talking to your own assistant instead of filling in forms.
Mint a personal access token — or sign in through the browser for clients that use the connector flow — and your assistant can work in your real library. Copy-paste setup is provided for each client, and tokens can be named, listed and revoked at any time.
Your AI writes the phrases and Immersful renders the audio, cards and quizzes. It can create courses, curricula and lessons, read a whole lesson back — every card, podcast script, cloze blank and guide — and poll a lesson until its audio is ready.
Rename things, replace a lesson's phrase list, edit one phrase surgically without disturbing its image or design, add or remove a phrase, change the cadence, and reorder phrases, lessons and curricula — with the learner-visible order updated in lockstep.
Set a card's picture, upload art, choose which words get blanked in the cloze quiz, and lay out where text and image sit on each face — reading the layout back with warnings when text would overflow or collide.
Draft a two-host segment for free with the same engine, host pairs and tone presets as the web designer, then spend credits only when you approve it — with an exact cost check first.
An in-app reference lists every tool, its inputs, and a cost badge saying whether it's free, uses free audio against a daily cap, or spends voice credits. Deleting is deliberately not offered. Every reply names the build that answered, so a client holding a stale tool list can tell.
Built and working internally, but not something you can get yet. Listed here so the rest of the page can be taken at face value.
Native apps carrying the same library, player, cards, quiz and speaking practice — with background listening, lock-screen and headphone controls, and haptics — are built and in testing, but aren't on the App Store or Google Play yet.
Browsing your languages, curricula and lessons on the car screen, with a Continue row that picks up where the phone left off, ships inside those same apps.
The print-ready PDF is live today. Ordering a finished deck cut and shipped to you is not — that's coming from Pat's Flash Cards.
The delivered library, all three study modes and the full review schedule are free on any account.
