About Affex
What is Affex?
Affex was built to eliminate fragmented study tools. We integrate an enterprise-grade spaced repetition engine (SRS) for long-term memory retention with structured unit courses and interactive progression.
Designed for high-performance learners (languages, medicine, certifications, and exams), Affex lets you natively import Anki decks or build your own learning trails powered by Half-Life Regression — all with daily streaks and 100% free on every platform.

FAQ
Frequently Asked Questions
Is Affex free?
Yes. Affex will be 100% free on every platform: the desktop app for Windows, macOS, and Linux, and the iOS and Android apps, which launch together. That includes features some competitors, like Anki, charge for on iOS.
Is Affex like Anki?
Affex uses the same spaced repetition science as Anki and natively imports your existing .apkg decks, but adds a modern interface and gamification without requiring any add-ons.
Is Affex like Duolingo?
In spirit, yes: Affex borrows Duolingo-style daily streaks, XP, and per-lesson energy, but applies them to your own flashcards and courses instead of a fixed curriculum, so you can gamify any subject.
Does Affex support structured courses, or only flashcards?
Both. Alongside spaced repetition flashcards, Affex includes structured courses with interactive lessons and progress tracking, so you can combine guided learning paths with SRS review in one app.
When does Affex launch?
Affex hasn't launched publicly yet. Join the waitlist to be notified as soon as it's available on your platform.
