Kestimo is a language app for the plateau. It watches what you actually do — the cards you miss, the words you tap while reading, the sentence you stumble over out loud — and picks what comes next from that. One memory across every skill, instead of a fixed tree that ignores you.
Bring your own article or podcast and it becomes the lesson. Bring nothing and it fills the gap itself.
I'm building this in the open. You'll get occasional notes on progress and first access when there's something to use. Nothing else, no noise.
Thanks — I'll write when there's something real to open, not before. If you want to tell me more about what you're stuck on, just reply to that first email.
The path is a sequence of concepts, not a sequence of lessons.
Prepositions, then past tense, then subordinate clauses. Where you meet each one is interchangeable — your article, your podcast, or something generated because you didn't bring anything that covers it.
Missing a tense on a flashcard, stumbling over it while speaking, and misreading it in a text are the same signal. Nothing else joins them up, so nothing else can act on them.
Open it and it says: these 20 cards, this paragraph, one speaking scenario. It talks to you only when it has something specific to say — no streaks, no XP, no cheerleading.
It knows what you couldn't do six weeks ago. “This paragraph was above you in March — read it now.” That's the measure, not a streak counter.
Good tools exist. None of them remember you across everything.
| Memory of you | Guidance | Reading & listening | Speaking & writing | |
|---|---|---|---|---|
| Flashcard apps | Total | None | — | — |
| Gamified courses | None | Fixed tree | Yes | Weak |
| AI conversation apps | Per session | None | — | Yes |
| Reading tools | Reading only | None | Yes | — |
| Kestimo | Across all skills | Adaptive | Yes | Yes |
Not a knock on any of them — I use several. The gap is that nothing connects input and output with a memory that spans both.
Nothing to try yet. Put your name down and I’ll show you the first thing that works.
