slash-editor

slash-editor gives your React app the Notion block experience: a slash menu, drag handles, nested reorder, turn-into, comments and real-time collab. It runs on a headless Tiptap v3 core. The UI arrives through a shadcn registry, so the components land in your repo and follow your Tailwind tokens. Tables, columns, Mermaid, AI via your own model, markdown import/export. MIT end to end, no paid tier, nothing hosted.
