Sift

Sift reads the page you're on and answers your questions about it, in a side panel next to the page. HOW IT WORKS - Open any web page and click the Sift icon. Ask a question. - If the page covers it, the answer comes from the page, with quotes you can click to see highlighted in place. Each quote is checked against the page text, so a made-up quote is rejected. - If the page doesn't cover it, Sift searches the rest of the same site and answers from what it finds. These answers are labeled "from the web". - Select text on a page, right-click, and choose "Ask Sift about this selection". - Long pages are searched locally, so questions about the end of a long article still work. - Share a thread as a link. The thread travels in the link itself; no account and no server copy. POWERED BY NVIDIA Nemotron models served by Nebius Token Factory, with Tavily for site-scoped search. PRIVACY - Sift reads a page only when you ask a question about it, never in the background. - The page text, your questions and the page URL are sent to Nebius Token Factory to produce the answer. Search queries go to Tavily. - No account, no analytics, no ads. Conversations are kept only until you close the browser. - Works out of the box through a free demo server with daily limits. Add your own Nebius and Tavily keys on the options page to call them directly; keys stay on your device. Open source: https://github.com/aishahsofea/sift
