A web app for writing and sharing documents

Features

• A fast, lightweight document-writing web app that still supports rich blocks and multiple pages
• Developed with the goal of finding a balance between Notion and Google Docs
• Create & write documents instantly, even without an account
• Easy sharing, with read and edit links
• Document sync across devices via email login
• Rich block support: canvases, subpages, RSVPs, polls, etc. can be added
• Clean design: laid out nicely like a published web page
• Use cases: one-off collaboration, running events, quick note-taking, etc.
• Example documents
  • A presentation on Slöjd, traditional handicraft education
  • Documenting a website redesign
• Technical features
  • TypeScript + React & Next.js + Supabase + Replicache + TailwindCSS
  • Real-time sync and client state management using Replicache
  • Datomic-style data model (entity-based graph structure)
  • Uses ProseMirror (every text block is managed as a separate ProseMirror instance for flexibility)
  • Open-source project (leaflet's GitHub Repo)
• Future development plans
  • Improved document management (adding search, tagging, collections, etc.)
  • ATProto and Bluesky integration (developing an AppView for document publishing and a rich text document standard)
  • More blocks (tables, code blocks, etc.)
• Strengths
  • Excellent list handling
  • Custom theme support
  • Optimized keyboard input handling on iOS Safari
  • Side-scrolling multi-page interface
