  Multi-model AI assistant in a browser side-panel, on any tab.

  A Chrome extension and web app that opens a Claude / GPT / Gemini / DeepSeek panel on any page (Ctrl/⌘+M) to summarize articles, chat with PDFs, draft replies on Gmail and LinkedIn, and answer alongside Google results. One subscription spans many models on a shared query-credit allowance.

  AI insight: One of India's most-installed Chrome AI extensions, 1M+ users; its 'unlimited' Pro plan is really a fair-use query-credit cap.

  Web-highlighter + AI extension. Save passages from any page, then ask AI for summaries, related ideas, or chat across your knowledge base. BYO key keeps your reading history private.

  AI insight: Built on a social highlight network, but BYO-key means your reading history stays yours rather than feeding a vendor.
