Investigate something.
Follow a question from discovery to evidence. Examine what sources support, what they dispute, and what remains unknown.
Quick Scan · Discover sources
Find source excerpts in a lightweight scan. Evidence is unverified; no conclusion or saved case.
Discover evidence →VERIFIED INVESTIGATIONDeep Scan
Examine supporting and conflicting evidence. Your investigation continues in the background and saves a private case.
Start an investigation →Start from a material.
Bring a link, document, photo, video or file into your private workspace. Review text or add observations, then return to Investigate with a draft you choose to load.
Saving requires sign-in. Select Read page to retrieve link text. Uploads are not verified or automatically analyzed. Video tools offer a local three-frame preview and, where available, a separate, explicitly consented AI review of supported MP4/WebM clips up to 60 seconds and 8 MiB. AI video review samples two frames per second; supported audio can provide editable speech text. Results are unverified, can miss or mishear details, and do not establish identity, authenticity or complete video analysis. A Deep Scan starts only when you explicitly run it.
Your investigations are private by default.

Evidence you can inspect
Completed cases preserve the exact excerpts assessed, accepted citations and withheld claims. Automated verification describes captured evidence; it does not establish universal truth.
