A coach that remembers what you’re about to forget.
Alpha Tesseract is a language-learning app with an AI agent for a teacher. It listens to every sound you say, keeps track of what you remember and what is starting to fade, and plans each lesson around that, live. No rigid templates. No same path. No same words every time.
No two learners get the same lesson.
Learn English, Tamil, Hindi, Telugu, Kannada, Malayalam, Bengali, Marathi, Spanish, French, German, Japanese or Arabic. More languages are on the way.
You said weryvery
Second try very
92 Nailed it!Courses and apps are built once, then repeated for every learner, word for word. Here is what that leaves behind.
no more rigid templates
Every lesson is planned live, around what you just said.
no more the same path for everyone
Your path bends to you: back when a sound slips, past what you already know.
no more the same words every time
Fresh words and sentences, chosen for the sounds you need right now.
no more “wrong, try again”
You hear exactly which sound slipped, and how to fix it.
no more explanations in a language you’re still learning
The fix, explained in the language you think in.
no more the same recorded video
She shows you how to shape any word, whenever you ask.
no more forgetting last month’s lesson
Reviews arrive just before a sound would fade.
no more grading yourself
Your voice is measured, sound by sound, out of 100.
Alpha Tesseract is agentic. There is no lesson script waiting for you. After every word you say, your coach updates her map of what you know, weighs what you are about to forget, and decides what happens next.
What the coach decided, minute by minute. Nothing here was written in advance.
Behind every lesson is an AI agent that keeps a living picture of what you know: what is solid, what is slipping, and what is about to fade. Every time you speak, it listens, remembers, and decides what comes next.
Sounds build into words, and words into sentences. Something new opens up only when what sits underneath it is steady, so you never build on shaky ground.
Steady means right again and again, days apart. Not one lucky try.
You never have to grade yourself. Each attempt is scored out of 100, sound by sound, and that score tells your coach how well something has really stuck.
Memories fade a little every day. Your coach tracks that fade for every sound and word you learn, and brings each one back just before it slips away. Every time you get it right, it stays with you longer.
Drag the sliders to see it.
At every moment your coach weighs everything you could practise: a slip from today, something about to fade, a new sound that opens up dozens of words. The most useful one goes first. If an old mistake comes back, it jumps straight to the front.
| Could practise now | How urgent |
|---|---|
| v in “village”picked nextslipped today, and it’s in hundreds of everyday words | |
| v or w pairsjust opened up, unlocks dozens of new words | |
| “school”learned last week, starting to fade | |
| æ in “cat”brand new, can wait a little |
Pick the language you want to learn and the one you think in. Your coach knows the slips speakers of your language tend to make, hears them, and talks you through the fix in your own words. Below, she helps speakers of 12 languages with tricky English sounds. Tap one to hear her.
