What is it?

ClaudePrism is a native desktop app for writing scientific papers, theses and other LaTeX documents. Projects are stored and compiled on your own disk, with LaTeX compilation handled by an embedded Tectonic engine that works offline after its packages are cached on first use. It is built with Tauri 2 and Rust, and is positioned as an open-source, local-first alternative to OpenAI Prism's cloud workspace.

Claude is available inside the editor as a chat assistant that can edit files, run bash commands and search the project. The app integrates uv for creating project-level Python virtual environments, and the Claude Code agent uses that environment when running analysis or plotting scripts. A catalog of over 100 domain skills from K-Dense Scientific Skills, covering bioinformatics, cheminformatics, machine learning and clinical research, can be installed globally or per project.

Every save is recorded as a snapshot in a local Git repository, with labels, diffs and restore support. Suggested AI edits appear as reviewable diffs that can be accepted per chunk. Other features include a MuPDF-based PDF preview with SyncTeX navigation, a screenshot-to-chat capture tool, and Zotero bibliography integration. AI features send prompts and file contents to Anthropic's API.
