Gamma PDF launches as an open-source, self-hosted AI PDF reader

Gamma PDF is an open-source, self-hosted PDF annotator that combines highlights, outliner notes with live Markdown and LaTeX, and an AI that answers questions about papers with cited jumps back to the passage, using the user's own Anthropic or OpenAI key or a paid ChatGPT plan. It runs as a desktop app on Windows, macOS and Linux, as iPad and Android apps, and as a single Docker image, storing data in SQLite and files in one folder with no account or telemetry. Codex, Claude Code and any MCP client can search and read papers, notes and highlights read-only for one approved workspace.
