Notty
What Notty is
Notty is a free, open-source notes app for Android, iOS, macOS, and the web. It combines rich editing, real-time collaboration, and offline-first operation. The editor supports slash commands, Markdown shortcuts, block editing, headings, lists, task lists, code blocks, and links. Notes synchronize between devices and collaborators over WebSocket using Yjs, which merges changes automatically. Notes remain available locally without a connection, with queued edits syncing after reconnection. The native macOS app uses a local SQLite database and supports two-way Markdown synchronization with the Documents/Notty folder. Notes can be shared by email or link with view or edit permissions, live cursors, and collaborator presence. Passkey verification, with biometric or PIN authentication, can lock sensitive notes, including shared ones. Authenticated users can publish notes on username.notty.page subdomains, customize appearance and metadata, and provide RSS 2.0 feeds. Color-coded folders organize notes by drag and drop. Sign-in supports passkeys, Google, GitHub, Apple, or anonymous access.
