Spaced repetition without building a deck
Upload the chapter you have to know cold. Tali writes the questions and schedules them — what you miss comes back tomorrow, what you know comes back in a month.
Start reviewing freeHow a chapter turns into a review queue
Spaced repetition is not the hard part — everyone knows it works. The deck is the hard part. Writing a good question takes longer than reading the page it came from, so the deck never gets finished, the schedule never gets going, and by exam week you are cramming like everyone else. Tali removes that step entirely: the questions come out of your own material, and the schedule starts the moment you answer one.
1. Upload the material you have to retain
The lecture deck, the textbook chapter, the standards document, the 300-page curriculum. Tali reads it and writes practice questions from it — single choice, multiple choice, fill-in-the-blank, true or false, and open-ended questions it reads and marks in prose. You do not sit there typing out prompts and answers.
2. Answer a question once. That is the enrolment.
Every question you answer joins your review queue automatically, whether you got it right or wrong. There is no add-to-deck button because there is no deck to add to. Your queue is simply everything Tali has asked you, ordered by the date you are about to forget it.
3. Come back on the day you are told
Your review page shows what is due today and nothing else. Each item returns with its answer and its explanation; you say whether you actually had it — Again, Hard, or Easy — and that one tap sets the next date. Reviews earn XP and count toward your daily goal, so keeping the queue clear keeps your streak alive.
Why this is not a spaced repetition app with an import button
The schedule is the product, not a setting
Tali runs SM-2, the algorithm SuperMemo introduced. In practice: recall an item and it comes back a day later, then six days later, and after that each success multiplies the gap by that item's own ease factor, which starts at 2.5. Fail it and the interval drops straight back to one day. The ease factor moves with your ratings and never falls below 1.3, so the material you personally find hard stays close and the material you find obvious walks out to weeks and then months.
You never write a question
The most common way a review habit dies is the deck-building session you keep postponing until it is too late to matter. Tali generates the questions from the pages you uploaded, so the queue is already populated before your motivation runs out — including the boring, necessary items you would never have had the patience to make yourself.
When self-rating is too generous, answer a fresh one
Telling yourself you knew it is fast, and it is easy to cheat. Any item in the queue has a variant button: Tali writes a new version of that same question and marks your answer properly. Get the variant right and the original moves forward in the schedule — you graduated it by answering, not by grading yourself.
Every item still knows where it came from
Each question in the queue was generated from a specific piece of your material and carries its explanation with it, plus an explain button when the explanation is not enough. You are never staring at a fact you copied out of context six weeks ago and can no longer place.
Who ends up living in the review queue
The certification with a long runway
CFA, PMP, CPA, actuarial papers. You will finish reading the curriculum months before you sit the exam, and the whole problem is what is still in your head by then. Answer the questions as you go through each reading, and the schedule keeps chapter 2 alive while you are busy with chapter 14.
The semester that ends in one big exam
You learned week three's material in week three and have not touched it since. Upload each week's slides as they come, answer the questions once, and the finals-week problem — nine weeks of material you half-remember — largely does not happen.
Terminology you simply have to know
Definitions, statutes, drug names, accounting treatments, vocabulary in a language you are learning. There is no clever shortcut for this material; there is only being asked again at the right interval. Tali takes the terms from your own textbook rather than a generic list, and can ask you in the language you think in.
Questions people ask before they upload anything
You get free tokens when you create an account, with no card required. Generating notes and questions from a file spends tokens; reviewing what is already in your queue spends none. The schedule itself never bills you — you can drill an old chapter every morning for a month without spending a thing. Asking for a fresh variant of a question is generating a new question, so that one does cost tokens. There is no subscription; you top up only when you generate something new.
SM-2. The first successful recall of an item sets the next review one day out; the second sets it six days out; from then on each success multiplies the interval by that item's ease factor, which starts at 2.5 and rises or falls depending on whether you rated the recall Easy, Hard, or Again. It never drops below 1.3. A failed recall resets the interval to a single day and the item starts climbing again. The numbers are not a marketing metaphor — that is the arithmetic running on your queue.
No. That is the whole point. Tali generates them from the material you upload — single choice, multiple choice, fill-in-the-blank, true or false, and open-ended questions that it marks and comments on. You review the ones it wrote. If a particular question is not useful, skip it; the ones you answer are the ones that get scheduled.
PDF, DOCX, PPTX, Markdown, plain text, and photos or screenshots of pages (PNG, JPG, WEBP, HEIC). Up to 30MB per file. A textbook is better uploaded a chapter at a time — the questions come back tighter, and you will be studying chapter by chapter anyway.
They are written from your file rather than from whatever a model half-remembers about the subject, so they stay on your syllabus and use your material's terminology. It is still AI, though: it can misread a table or ask something the chapter never really claimed. Every item carries its explanation, and there is an explain button when you want the reasoning — if something looks wrong, check it against the source you uploaded.
Nothing expires and nothing is deleted. The review page shows you what is due, oldest first, twenty at a time, and you work through as many as you have time for; the rest stay due until you get to them. Items you have clearly forgotten after a long gap simply reset to a one-day interval, which is exactly what should happen to them.
