The Chrome Web Store rounds user counts down to the leading digit, so the user line moves in steps. The ratings count is exact and is the better signal of real adoption.

About Web Butler

A browser extension that puts an AI butler on every page: a compact prompt pill that answers questions about the page, runs background tasks, writes long-form reports into the Chrome side panel, and installs persistent "site extensions" (user scripts) that keep modifying pages across visits. Agents run as CLIs (Codex, Grok, Claude Code) on a per-user Freestyle sandbox VM, driven over ACP (Agent Client Protocol) by a local server.
