v1.3.0 Latest

Email, Calendar & an extensible tool layer

Paperus grows past notes into a quiet local-first workspace — mail, calendar and a pluggable tool layer, all driven by the built-in Claude Code brain.

  • Email (beta) — connect IMAP/SMTP accounts, a unified All inboxes across every account, newest-first sync of Inbox/Sent/Drafts/Spam/Trash/Archive, background body prefetch, and agentic compose with a send-approval gate.
  • Calendar — connect external calendars over CalDAV (iCloud, Fastmail, or generic app-password); events sit alongside your notes and due dates.
  • MCP — a Model Context Protocol manager: add MCP servers and scope their tools per agent inside the brain.
  • New surfaces — Tasks, Calendar, Inbox and Email panels built on a React-island platform (@medusajs/ui), folded into one clean sidebar with thin line icons.
  • Agent presets + a custom-agent builder, redesigned chat sidebar, and live model picker with reasoning effort.

v1.2.0

The app is now Paperus

A clean, ownable name for a tool that isn’t a knock-off of anything.

  • Renamed across every surface to Paperus — window, dialogs, mobile headers and docs. Existing installs keep all their notes and settings.
  • First-run onboarding — a one-screen welcome: start writing, create a team, or join with a link.

Self-hosting, optional accounts & the Claude Code brain

Run the whole thing on your own box, or keep it pure peer-to-peer — one switch picks the trade-off.

  • Self-hosting — bring up the full web app + relay on your own domain with one docker compose; automatic HTTPS (Let’s Encrypt), no database.
  • Two modes — NL_MODE=online for an always-on, end-to-end-encrypted box that’s available 24/7, or p2p for a pure relay that stores nothing.
  • Optional accounts — a lightweight access gate that never holds your encryption keys.
  • In-app server connect — point the desktop app at any relay or team server from settings.
  • Company brain — a Claude Code assistant with a live model picker, reasoning effort, conversation threads, file attachments and agentic skills.
  • Delta auto-update so upgrades download only what changed.

v1.0.8 First public release

Paperus goes open source

A local-first, zero-account, pure-P2P Notion alternative — your notes are plain Markdown files on disk that never leave your machine until you choose to share.

  • Native Markdown editor on CodeMirror 6 with live preview — callouts, toggles, columns, math, Mermaid, images and transclusion.
  • Real-time collaboration over Yjs CRDTs; peer-to-peer WebRTC sync brokered by a tiny stateless relay.
  • End-to-end encryption (libsodium) — the relay and your peers only ever see ciphertext.
  • One-link teams — no accounts, no login; share a single invite link to collaborate.
  • Signed & notarized universal macOS app (Apple Silicon + Intel).
  • Plugin system and a native iOS & Android companion you can build from source. Licensed AGPL-3.0.
