Shard

Shard is a modern, fast, and fully offline personal knowledge management (PKM) workspace, Markdown note-taking app, and LaTeX/TeX document editor.

Built on the "Local-First" philosophy, Shard stores all your notes, thoughts, and documents as open plain-text files on your device. No cloud accounts required, no telemetry, and zero vendor lock-in — you own your data completely.
