Letsi is a personal AI English tutor with persistent memory. It calls you every day, knows your goals and every mistake you've ever made, and tracks your real trajectory to an IELTS band — not a streak, not a badge, a credential.
Built for IELTS candidates and serious English learners across the region — and beyond.
Designed to replace the gimmicks with something that works
Generic chatbots reset every session. Course apps hand you the same content as everyone else. Letsi is different: a tutor with a compounding model of you — your errors, your interests, your exam date — that gets sharper every single day you show up.
Amnesiac. Reactive. Gamified into a dopamine loop that doesn't move your real level.
Persistent learner model. Proactive daily calls. A credible AS-IS → TO-BE band you can actually trust.
"Talk to AI" is commoditized. Our defensibility isn't the voice — it's what sits underneath it.
An event-sourced, ever-growing model of each student: per-skill estimates, clustered error patterns, spaced-repetition vocabulary, pronunciation trouble-map, and relationship memory. The longer you stay, the harder we are to leave.
A calibrated IELTS band prediction, validated against real exam results and certified human raters. The goal: within ±0.5 of a candidate's true band. That accuracy is what turns a study app into a trusted assessment standard.
The tutor initiates. Every morning it opens with a call that references your own history — "third time this week with past-simple questions." Presence, not a feature grid, is what builds the daily habit and the relationship.
No feature grid, no map, no menu to get lost in. Open the app and there's a single call button — the tutor takes it from there.
The tutor reviews yesterday, links today's issues to past patterns, answers your questions, and names today's plan — in ~2 minutes.
A short, curated lesson chosen overnight for exactly where you are. New vocabulary flows straight into your review deck.
Personalized drills — including at least one built from your own past mistakes and the flashcards due today.
A voice roleplay set in something you actually care about. For IELTS: full Speaking Part 1–3 simulations with per-criterion feedback.
Every night, an analysis pipeline rebuilds your model and prepares tomorrow's materials — the "we spent the night preparing for you" ritual.
IELTS is a high-stakes, deadline-driven, globally recognized exam taken by millions each year — a market where learners already pay for outcomes. We start there, own the credibility, then expand.
Deadline-driven demand. Exam dates create urgency and willingness to pay — the best possible wedge.
Complement, don't compete. Bring-your-own-material turns prep schools into a distribution channel — Letsi becomes the practice layer on top of any curriculum.
Disciplined unit economics. Voice cost budgeted to ≤ $0.20 per active user-day, with track-based pricing engineered for margin from day one.
"Letsi is not a course app. It's a personal tutor with persistent memory — one that opens every session, assigns work made for you, and tracks where you're really headed. Our aim is to become the industry standard for IELTS, and one day a trusted continuous credential."
Content and methodology led by an IELTS 9.0 instructor with 11 years of teaching experience — author of the methodology Letsi is built on.
