One-click AI assistant for browsing, writing and research
A Chrome extension that summarizes, searches and writes directly over the page you are on, without switching tabs.
Access to leading models from several vendors in one place, so you can pick the best fit for each task.
Build reusable knowledge bases from your own documents and code, then query them repeatedly for tailored answers.
Turn a prompt into flowcharts, mindmaps, charts and other diagram types for reports and presentations.

Free, signup-free AI replies for LinkedIn, Twitter/X and Instagram using your own OpenAI key.
Open the extension icon in the comment interface on LinkedIn, Twitter/X or Instagram and it drafts a reply for that specific thread.
Paste your own GPT API key in the extension settings — no account, no proxy server, and no data collection per the developer's disclosure.
Write instructions to match your brand voice or personal persona so generated comments sound like you rather than a default chatbot.
Runs as a lightweight Chrome extension (about 24 KB) directly in the sites you already use, so there is nothing heavy to install or manage.
