Tali works only from the material you give it, quotes the exact line behind every answer, and shows you which topics you only think you've got.
Because they don't have your textbook.
Tali quotes the exact line it worked from. If it can't find the line in what you uploaded, it says so instead of making something up.
A number tells you nothing when you passed the mock and failed the real one. Tali gives you the topics you've verified, the ones you only think you know, and the ones you haven't touched.
Redoing a question you've seen tests your memory of the answer, not your understanding. Tali rebuilds the same concept in a situation you haven't seen.
Every one you got wrong stays in one place, grouped by topic. Step away for a month and Tali tells you where you stopped and what's most likely gone.
From your own material to a straight answer about where you stand
The textbook, the slides, the PDF you already paid for
Every point quotes the exact line it came from
Same concept, a situation you haven't seen before
Verified, false confidence, or not covered yet
Tali was built for the exam you can't afford to fail twice.
You're working full time and studying at night, off a course you already paid thousands for. The question isn't whether you've read it — it's whether you'd get it right on a question you haven't seen.
Long material, scenario-heavy questions, and a date you already booked. Tali turns your own study guide into situations you have to reason through.
Volume is the problem, and so is knowing which parts have quietly slipped. Tali tracks what's verified and what's only familiar.
Any exam where failing costs you a promotion, a salary band, or another six months. Bring your own material — Tali works off that, not off the open internet.
Everything you need to know to get started
Tali is for all lifelong learners! Whether you're a student preparing for exams, a professional learning new skills, or simply exploring a new hobby — if you have material to study, whether that's a PDF, a slide deck, a document, your own notes or even a photo of a page, Tali can help you learn it efficiently.
Very accurate! The AI generates notes and practice questions based on YOUR uploaded content, ensuring 100% relevance to what you're studying. Exercise types include single choice, multiple choice, fill-in-the-blank, true/false, and open-ended (with AI auto-scoring) for comprehensive learning.
Your uploads travel over an encrypted HTTPS connection. Your materials are only used to generate your own study content — we never sell them, and the only third party they reach is the AI provider that processes them to write your notes and questions. You can delete anything you've uploaded at any time.
PDF, PowerPoint (PPTX), Word (DOCX), Markdown and plain text, plus images (PNG, JPG, WEBP, HEIC) — so a photo or scan of a page works too. You can also import a web page by pasting its link. After uploading, AI automatically identifies the content structure and extracts key knowledge points. Maximum file size is 30MB. We recommend keeping files under 50 pages — split larger documents by chapter.
Tali has a built-in continuous learning system to help you build daily study habits. Complete your daily learning goals to maintain your streak and unlock achievement badges.
Yes — and you don't have to tell it that the file is an exam. Tali reads the upload and classifies it first. If it's a problem-solving paper, it pulls out each question as it appears on the page and writes a note for the exam point behind it. If it's reading material or a handout, it summarises the content and generates practice from that instead. The routing is decided from what's inside the file, not from its name or type.
Tali redraws them. For every question carrying a figure, it produces a clean vector redraw alongside a full worked solution — the steps, not just the final answer. The redraw is generated by AI from the original image, so straightforward geometry comes out faithful while complex constructions can lose detail; the question text itself is always kept as it appeared. Solutions are written once and stored with the question, so reopening a walkthrough doesn't regenerate it.
Every exercise you answer becomes a review item scheduled by SM-2, the spaced-repetition algorithm popularised by SuperMemo and Anki. Answer correctly and the gap before it returns grows — one day, then six, then multiplied by that item's own difficulty factor. Answer wrong and the interval resets to a single day. Scheduling runs on the questions generated from your own uploads, so what comes back is your material.
You get 600 free Tokens upon registration, enough to experience all core features — AI notes, practice quizzes, and more. It's enough for a complete learning session. You can purchase more Tokens anytime afterward.
Generating a note costs 3 Tokens (10 for an exam-focused note). Practice questions cost 10 Tokens each, so a set generated from one note costs roughly 180 Tokens. Having an open-ended answer graded by AI costs 10 Tokens, and AI chat costs 4 Tokens per message. When you run out, top up anytime — no monthly fees, pay only for what you use.
We keep pricing simple and pay-as-you-go — no subscriptions, no hidden fees. $20 gets you 4,200 Tokens; $80 gets you 21,000 Tokens. Refer a friend and you'll both get 200 Tokens as a bonus.
Token purchases are final — except where the law requires otherwise, we can't refund a purchase once it's complete. You get 600 free Tokens on signup, so you can try the core features before spending anything. If something goes wrong with a payment, email us and we'll help.
Super easy! 1. Create an account (30 seconds) 2. Upload your material — a PDF, slides, a document, notes, an image, or just paste a link 3. Wait for AI to generate notes and quizzes 4. Start your learning journey. No complicated setup needed.
Upload it and Tali takes it from there. Drop a PDF into a notebook — or a DOCX, PPTX, Markdown, plain text, a photo or screenshot (PNG, JPG, WEBP, HEIC), or paste a web page URL — and extraction starts immediately. Note generation runs in the background, so you can close the tab and come back; the notebook refreshes itself as each source finishes. From those notes Tali generates practice questions you can answer and chat about.
Yes! Tali works on all devices — phone, tablet, and desktop. Learn anywhere, anytime — during your commute, lunch break, or wherever you have a few minutes.
Email us at xnjiang@qumge.com and we'll get back to you as soon as we can. Tell us what you were trying to do and what happened instead — it helps us sort it out faster.
10 languages: English, Chinese, Japanese, Korean, Spanish, French, German, Portuguese, Russian, and Italian. No matter what language your materials are in, AI can accurately extract key points. The interface language can be switched anytime too.
Upload one chapter you're worried about. Tali will show you what you'd get wrong.

Three typical ways to put Tali to work
Preparing for a professional exam
Instead of reading the textbook a fourth time, drop a chapter in. Tali turns it into notes and questions, and when you get one wrong it walks you back through the part you missed.
Studying in a second language
When the material is in one language and you think in another, Tali can explain it in the language you're comfortable with, then quiz you in the one you're learning.
Picking up a new field mid-career
Documentation written for insiders gets broken into small questions you can work through a few at a time — and a chat you can stop and ask 'why' in.
