ContxtAI

Privacy-first browser extension that builds reusable AI context profiles and injects them into any chat.

Browser extensionfreeglobal

ContxtAI is a browser extension that lets users build reusable context profiles - their projects, preferences, and writing style - and inject them with one click into ChatGPT, Claude, or Gemini, instead of retyping the same background every conversation. It can also extract context from past conversations and locally scrubs sensitive data like passwords before anything is saved or sent, all stored on-device.
