OmniCanvas - Infinite second brain.

OmniCanvas is an infinite-canvas note-taking app for people who organize information spatially instead of in linear documents and nested folders. Notes, sketches, diagrams, images, and meeting transcripts live on the same zoomable workspace, connected by wiki-links and visualized in a graph view. The free tier costs $0 and includes unlimited notes and canvases, cloud sync, folders, tags, full-text search, graph view, Kanban view, and optional end-to-end encryption. Pro is $8/month and adds 10 hours of monthly meeting transcription, semantic search, AI actions and custom prompts, handwriting OCR, web and YouTube clipping, and REST API and MCP server access. OmniCanvas records meetings by capturing microphone and system audio directly - no bot joins your call - and puts the transcript and action items on the canvas beside your notes. OmniCanvas also publishes 40 free browser tools that need no account; the AI ones run locally, so files are never uploaded. On the web and macOS.
