Paper spider

A spider walks to the passage you ask for in any PDF. Uses your own Claude API key.

Ask a question about any PDF, and a small spider walks across the page to the passage that answers it. HOW IT WORKS • Open any PDF in Chrome. A round "Paper spider" button appears at the bottom right. • Press it. The PDF opens in the spider viewer. • Type what you are looking for, such as "What was the main result?" or "Where are the limitations?", and press Find it. • The quote shows at the bottom right away. The words light up on the page when the spider reaches them. • Find more looks for a different passage that answers the same question. WHAT YOU NEED • Your own Anthropic API key (from console.anthropic.com). Press "Claude key" once and paste it. • Without a key, text PDFs still work with simple word matching. Scanned PDFs and photos need the key, because Claude reads them as pictures. PRIVACY • Your key is stored only in this browser. • When you search, your question and the PDF text go straight from your browser to Anthropic. There is no other server. • No tracking, no analytics, no ads. OTHER • Dark page mode for reading at night. • Open PDFs or images from your computer with "Open a PDF or image". • Click anywhere on the page to call the spider over. • To read PDFs saved on your computer, turn on "Allow access to file URLs" for Paper spider in chrome://extensions. Paper spider is not made by or affiliated with Anthropic.
