One workspace
A space per subject. Drop in the syllabus, the slide decks and last week's lecture recording, and every tool is ready to work from them. This is the whole app, uncut:
In action
Not a screenshot — the app mid-thought. Each one solving a problem, drafting a paragraph, flipping a card, grading an answer. Pick the one you need; it's the same tool that opens when you sign in.
Spaced repetition
Most flashcard apps show you a card because a fixed number of days went by. Thaxas schedules with FSRS, which models how fast you forget each individual card and brings it back at the edge of recall — where the review is actually worth something.
Every review you pass pushes the next one further out. A deck you keep up with costs you less time each week, not more.
How the scheduling worksRecall over time
Study groups
One folder for the module. Somebody uploads the syllabus once and the whole group works from it — no re-uploading, no “which version is this?”. Invite with a code; there are no seats to buy.
Your flashcards, quiz scores and chat stay private. A study group should not turn into a leaderboard.
Organic Chemistry · Sem 2
4 members · 3 spaces
Focus
So everything that keeps you there sits in a dock at the bottom of the app, and keeps running while you work.
Lo-fi
166 tracks · 10 moods
Pomodoro
Keeps running while you move between spaces.
Breathing
Four counts in, four out. For the hour before the paper.
Students
The flashcards come back right when I'm about to forget them. My retention before finals has never been this good.
I photographed a circuits problem, told it to only solve part (b) with mesh analysis, and it did exactly that.
We share one folder for the whole module. The syllabus went in once and the whole group works from it.
Short-answer quizzes graded against a rubric, not string matching. It caught that my definition was half right — and said which half.
Six weeks of readings turned into one study guide I actually revised from. That's the whole product for me.

FAQ
PDFs, PowerPoint and Word files, plain text and Markdown, photos of handwritten notes (JPG, PNG, WebP, HEIC), and audio lectures (MP3, M4A, WAV and more) — up to 50MB per file. One space per subject, and there is no limit on how many spaces you make.
No, and we won't pretend otherwise. Thaxas is $8/month billed yearly, or $12 month to month, and every feature is in both — all eight tools, unlimited spaces and uploads, and shared folders for your study group. We'd rather be plainly paid than quietly convert you after a trial you forgot you started: there's an email before every charge, and cancelling takes two clicks and keeps your access until the period you paid for ends. The focus timer, lo-fi and ambient sounds are free to everyone, with no account at all.
Thaxas schedules flashcards with FSRS, the same algorithm serious reviewers use. It models how quickly you personally forget each individual card and brings that card back at the edge of recall, rather than after a fixed number of days. Every successful review pushes the next one further out, so a deck you keep up with takes less time each week, not more.
Yes. A folder holds shared spaces and shared material: someone uploads the syllabus once and the whole group works from it. You invite people with a code, and there are no seats to buy. What stays private is your progress — flashcards, quiz scores, review history and chat are yours alone, and a study group never turns into a leaderboard.
Yes. Thaxas works from whatever you give it, so it fits IB, A-Level, AP, IGCSE, GCSE, Abitur, Baccalauréat, CBSE, Gaokao, ENEM and university courses alike. You can set your curriculum in Settings so the tools phrase things the way your exams do.
Yes. Your uploads live in private storage tied to your account, are never shared with other users, and are never used to train models. Delete a space and its files go with it; delete your account and everything is removed.
Everything included from day one
No trial to forget about, no tools locked behind a higher tier. Start the term the way you mean to finish it.
