Sitegeist is a Chrome 141+/Edge browser extension that runs as a sidebar panel to automate web tasks, extract data, fill forms, and export results to documents or spreadsheets using a user-selected AI provider.
It requires a user-supplied API key or existing subscription (Claude, ChatGPT, Copilot, Gemini), processes everything locally, and collects no data. Licensed under AGPL-3.0, it depends on two companion repos, includes a configurable CORS proxy for subscription logins, and deploys a static marketing site to sitegeist.ai.
Gemma Gem runs Google’s Gemma 4 model entirely on-device via WebGPU — no API keys, no cloud, no data leaving your machine. - kessler/gemma-gem
