Good mock scores. Still failed.

If that's happened to you, the problem isn't effort — it's that nothing you're using can tell you which topics you only think you've got. Tali works from your own material, quotes the exact source for every supported point, and gives you that list.

How it works

Three steps, on material you already own.

Upload one chapter you're worried about

A PDF, slides, or notes you already have. Tali reads only that.

Get answers with the source attached

Every supported point quotes the exact line it came from. If Tali can't find it in what you uploaded, it says so rather than inventing one.

Get tested on a scenario you haven't seen

Not the same question again — that only tests whether you remember the answer. Same concept, new situation.

Why this is different from asking ChatGPT

It has your material. ChatGPT doesn't.

A general model answers from broad training data and can't show which line in your material supports an answer. Tali answers from the chapter you uploaded and quotes that line.

It tells you when it doesn't know

If a claim isn't in your material, Tali marks it as unsupported instead of stating it confidently.

It measures readiness, not activity

Hours studied and mock scores both go up while blind spots stay put. Tali reports verified topics, false confidence, and untouched topics separately.

Your mistakes stay in one place

Grouped by topic, so a month-long gap doesn't mean starting over.
