About ContextOS

ContextOS keeps decisions and constraints in sync across the AI tools you already use. This extension is the browser half: opt-in capture from ChatGPT, Claude, Gemini, and Google AI Studio, plus insert of a compiled briefing into a new chat. Requires the ContextOS desktop app on the same computer (download at https://contextos.ca/download). Capture stays off until you enable each site in the side panel. The extension talks only to ContextOS on this machine via Chrome native messaging and localhost — it does not upload chats to contextos.ca. How to use: Install and open ContextOS desktop, then click Sync now so the Chrome helper is registered. Install this extension (Add to Chrome). Open the ContextOS side panel and turn on the sites you want. Chat as usual; enable Insert when you want a briefing in a new composer.
