Tessera

Save what you read, then ask questions across everything you've saved. Click the Tessera icon on any article and it lands in your library. Tessera writes a short summary and picks a couple of tags automatically, so the library stays browsable as it grows. Later, ask a question in plain language and get an answer drawn only from the articles you actually saved — with a link back to each one it used. What Tessera reads Only the page you explicitly save. Clicking the icon lets Tessera read that one tab. It never watches the pages you visit and has no access to any other tab. What happens to it Saving stores the page's title, URL and text in your library, and sends the text to OpenAI to generate the summary and tags. No analytics, no advertising, nothing sold. Sign in with Google. Free to use, with daily limits per account. You can delete your account and everything in it at any time from Settings. Your library lives at https://tesseraly.work
