A quiet layer for your browser. Capture what matters. Reuse it later. Take a breath in between.
Sonto lives in Chrome's side panel. Three things happen there:
Browse — Your clipboard history. Everything you copy flows in automatically. Pin what you need, tag it, search it. Related clips surface when you visit a page.
Zen — A slow feed for when you need a moment. Paintings from museums, philosophy essays, Mars photos, haiku. Content that respects your attention. Time-based: art in the evening, news midday, contemplative pieces at night.
Reuse — Saved prompts with color labels. Quick keyboard shortcuts. One-click export to Notion or Obsidian.
No accounts. No sync. No tracking. Everything stays on your machine.
