What is DeepVerify
Verify claims on any webpage, YouTube video, or live conversation — instant AI fact-checks backed by real sources. DeepVerify checks the facts in what you are reading, watching, or listening to, and shows you the sources behind every verdict.
WHAT YOU CAN CHECK
- Selected text: highlight a sentence on any page and check it from the right-click menu.
- A whole web page: DeepVerify finds the factual claims on the page and verifies them one by one.
- YouTube videos: claims from the video's transcript appear as cards next to the player, so you can check a video without opening a side panel. Turn on auto-verify to check each video as you open it.
- Live audio: start a live session on the current tab and claims from the audio are checked as they are spoken.
HOW A CHECK WORKS
1. DeepVerify extracts the factual claims from the content you chose. 2. Each claim is verified against web sources. 3. You get a verdict for each claim together with the sources it relied on, so you can read them yourself.

- Every check is saved to your history.
- Re-check a past claim later to see whether the verdict has changed.
- See your usage and manage your plan in the DeepVerify dashboard on factagora.ai.
YOUR DATA
- DeepVerify reads a page only when you ask it to check something, or when you turn on automatic claim detection or YouTube auto-verify in Settings. Both are off by default.
- Your browsing history and the list of sites you visit are not collected.
- A sign-in with a Factagora account is required to run checks.
- The extension creates a random install identifier and sends it, with the extension version and display language, to Factagora. When you sign in, it is linked to your account so we can understand how people get started. It does not include your email or the pages you visit.
