## What it is
Orbit is an experimental spaced repetition platform for publishing small review tasks embedded in texts (the mnemonic medium) and engaging with them over time. It is a TypeScript monorepo spanning client apps (web, mobile, desktop), a backend sync service, and reusable core libraries, primarily serving as a research vehicle for memory augmentation.

## Use cases
- embed spaced repetition review prompts into online textbooks and articles
- remember key details from what I read without manual flashcard creation
- build a connected cloud-based alternative to Anki
- sync review schedules across web, mobile, and desktop apps
- experiment with programmable attention and memory augmentation research
- ingest review tasks from around the web via APIs or embedded iframes

## When to choose
- you're an author wanting to embed review questions in educational texts like Quantum Country
- you're researching spaced repetition, memory augmentation, or programmable attention
- you want a cloud-synced, multi-platform SRS rather than local flashcard files
- you need reusable TypeScript libraries for task scheduling and data sync

## When to avoid
- you just want a polished, turnkey flashcard app for personal study (use Anki instead)
- you need a stable, feature-complete product with support guarantees
- you can't accept AGPL/BUSL licensing on the app and backend components
- you want a self-contained offline tool rather than a connected cloud service
