Vouch is a browser-native AI platform that brings powerful intelligence directly into any webpage you visit. No copy-pasting, no tab switching, no re-explaining. Highlight a claim and verify it, scan an article for bias, or chat with the page directly. The intelligence comes to you.
Reading online today is frustrating. You see claims you want to verify, jargon you don't understand, or bias you want to spot, but current AI tools break your flow. You have to copy text, open new tabs, paste content, and repeatedly explain context.
Vouch changes this completely. It works natively inside your browser. The AI automatically understands the current page, so you can highlight text, ask questions, or run full analysis with zero friction. The result is a seamless experience that feels like having a personal research assistant always available on every site.
