Cognito

AI-powered browser sidekick combining RAG, notes, and voice control

Browser extensionfree

Cognito is a free, open-source Chrome extension that acts as an AI-powered browser sidekick, combining retrieval-augmented generation, text-to-speech/speech-to-text, and note-taking so users can guide, query, and control their browsing using natural language, including local LLM support. It's for people who want an AI assistant that lives directly in the browser instead of switching to a separate chat tab for every question.
