Philosophy

Built for the browser. Owned by you.

Local-first

Your data lives in IndexedDB and chrome.storage.local on your machine. There is no Selfhood server holding your work hostage.

Side-panel native

Serious tools deserve real estate. Every extension is built for Chrome's side panel — not another toolbar popup you lose on click.

AI on your terms

On-device models by default. Bring your own key when you want more power — calls go straight from your browser to your provider.

Deep dives

Three to start with

Acceleration

Every download, in parallel

Aether splits files across multiple connections and reassembles them on the fly. Watch real throughput on the live flow meter while large files land in a fraction of the time.

  • Multi-connection segmented downloading
  • Live speed graphs and flow meter
  • Pause, resume, and retry that actually work
  • Every download, in parallel

    Living library

    Bookmarks that stay alive

    Every save gets an on-device summary, tags, and embeddings. Your library organizes itself into a browsable, breathing collection instead of a graveyard of links.

  • Automatic on-device summaries
  • Self-organizing tags and collections
  • Reading states and spaced repetition
  • Bookmarks that stay alive

    Resume briefs

    Your context, reconstructed

    Come back after a week and ThreadBack hands you a brief: what you were trying to do, what you found, what you decided, and the next step. No archaeology through 40 open tabs.

  • Goal, evidence, decisions, open questions
  • Generated on-device with Gemini Nano
  • One click back into the thread
  • Your context, reconstructed
