# Repetio AI

> Repetio is a modern spaced repetition flashcard app with AI-powered card generation. It helps students and professionals memorize large volumes of information efficiently by combining active recall, the SM-2 spaced repetition algorithm (Anki-compatible), and an in-app AI assistant.

Repetio is built for anyone with a high memory workload: medical students, law students, language learners, and working professionals. The core workflow is: upload your notes or slides → AI generates flashcards → study with spaced repetition → the scheduler surfaces cards at the optimal moment before forgetting.

## Core Concepts

- **Active recall**: Retrieving information from memory (rather than re-reading) is the most effective way to strengthen long-term retention.
- **Spaced repetition**: Cards are shown at increasing intervals based on how well you know them. The scheduler uses the SM-2 algorithm (the same algorithm that powers Anki).
- **Forgetting curve**: Without review, memory decays exponentially. Spaced repetition schedules reviews just before the forgetting threshold.
- **AI card generation**: Upload a PDF, image, slide deck, or paste notes — Repetio's AI (powered by OpenAI GPT-4o) reads the content and generates high-quality flashcard question/answer pairs.
- **AI study assistant**: During study sessions, ask the AI to explain a concept, give a memory hook, or clarify a confusing answer.

## Pricing

- **Free** ($0/month): Create and study your own decks manually, unlimited reviews, access to the public Explore library.
- **Pro** ($19/month): AI flashcard generation from uploaded files, file uploads (PDFs, images, slides, notes), in-app AI study assistant, advanced study insights, priority support.

## Blog

Repetio's blog covers practical study science: active recall, spaced repetition, AI-assisted learning, and building a calmer study workflow. Articles are written for students who want evidence-based techniques, not productivity hacks.

Published posts:

- [Active Recall and Spaced Repetition: How Top Students Actually Remember What They Study](/blog/active-recall-and-spaced-repetition) — Covers the forgetting curve, retrieval practice, how spaced repetition scheduling works, and how Repetio implements these principles. Aimed at medical students, law students, and language learners.
