Ensō

Search or ask from every new tab in the Zen browser.

A companion for Zen. The new tab becomes one box for sites, searches and questions, and ⌘E opens a sidebar that reads the page you’re on and can fill in forms, click and navigate for you. What you ask for runs; anything it comes up with itself, and anything that sends, pays or can’t be undone, waits for your Allow.

It runs on your Mac, on your own Claude subscription, with the claude.ai connectors and MCP servers you already use. The server only hosts the website, the update feed and optional sync between Macs, encrypted on the device so the server can’t read it.

The story

01Why it exists

I wanted the assistant in the browser to be part of the browser: the new tab, the page I am on, the tabs I have open. Ensō starts as one box. Type a site and it completes the address, type words and they go to your search engine, ask a question and it answers in the tab from your mail, calendar and files.

02Acting on pages, with permission

The sidebar reads the page, YouTube transcripts included, and can type, click and choose options, outlining each element it touches. What you asked for runs. Steps it proposes itself, and anything that sends, pays or can’t be undone, wait for your Allow. Banking, payment and health sites are never read or acted on.

03Nothing goes through my server

Conversations, memory, reports and the activity log are files on your Mac. Questions go from your Mac to Anthropic, through Claude Code signed in with your own subscription or an API key kept in the Keychain. The server on wicker-01 only serves the site, the update feed and the optional sync, which it stores encrypted with keys it never sees.
