It is strictly read-only. PageLens only reads the visible text of the current tab and sends it to Claude for analysis. It never clicks, types, fills forms, or submits anything on your behalf, unlike most "AI browser agent" extensions, there is no action/automation layer at all, which keeps the trust and risk profile much simpler. How it works Click the PageLens toolbar icon to open the side panel. Add your own Anthropic API key in settings (stored locally via chrome.storage, sent directly from your browser to Anthropic's API — it never passes through any third-party server). Ask a question, or use a quick action (Summarize / Explain simply / What should I watch for?). PageLens reads the current tab's text and headings, sends it with your question to Claude, and shows the answer in the panel. Install (unpacked, for development) Clone or download this repo. Open chrome://extensions in Chrome. Turn on Developer mode (top right). Click Load unpacked and select this project's folder. Pin the PageLens icon and click it to open the side panel. Add your Anthropic API key in the ⚙ settings panel.

Ideas for extending this Highlight-to-ask: right-click a text selection and ask about just that. Per-page memory: cache summaries so re-visiting a page is instant. Export chat as notes / send to a notes app. Support Firefox/Edge via the WebExtensions API (mostly a manifest tweak). Streaming responses instead of waiting for the full answer.
