Remnote

RemNote is an AI-powered note-taking, spaced-repetition, and PDF-annotation study platform founded at MIT and backed by General Catalyst, used by over a million students to take notes, generate flashcards, annotate PDFs and slides, and study with an integrated spaced-repetition queue and AI tutor. For developers, RemNote exposes a first-party front-end Plugin SDK (@remnote/plugin-sdk) — a React-first, sandboxed extension platform with a Rem API, hooks, widgets, and virtual embeds — rather than a hosted backend REST API. Plugins run either sandboxed in an iframe or natively on the main thread, with scoped access at the Rem, Document, and Powerup level, and are published through an in-app plugin marketplace after a code-review process.

Remnote is profiled on the APIs.io network. Tagged areas include Company, Note Taking, Knowledge Management, Spaced Repetition, and Flashcards.

Remnote’s developer surface includes changelog, documentation, API reference, getting-started guide, engineering blog, pricing, signup flow, and 14 more developer resources.
