Harbor is a private, cross-platform notes and personal knowledge app for collecting typed notes, documents, scans, photos, handwriting, web clips, and audio. It combines notebooks, stacks, tags, workspaces, tasks, reminders, templates, and version history so information can be kept in a structured archive without requiring Markdown or a complex filing system.
Its capture and retrieval features extend beyond ordinary text notes. Harbor can OCR photos, scanned PDFs, handwriting, and email attachments, highlight matches inside source files, and turn recordings into searchable, speaker-labeled transcripts. Notes and files can be accessed on Mac, Windows, iPhone, iPad, Android, and the web, with offline support described across the product.
For privacy and portability, users can enable zero-knowledge encryption for individual notes or notebooks, export their data in HTML, Markdown, or Evernote ENEX, and connect external tools through the API, CLI, or MCP. Harbor offers a free plan and a paid Unlimited plan.
