Install the extension
Add ClaimCircle from the Chrome Web Store. It loads quietly in the background and only activates when you draw a circle.

How it works
Three steps. Zero friction.
No copy-paste. No new tab. Draw a circle around anything you want to verify and ClaimCircle does the rest.
Circle any claim
Move your cursor in a closed loop around a post, paragraph, or image. ClaimCircle detects the gesture and captures just that region.
Get a sourced verdict
The backend gathers evidence from trusted sources and returns a cautious verdict — Supported, Contradicted, Misleading, or Unclear — with links.
In action
Works everywhere you read.
From celebrity gossip to health claims to investment takes — ClaimCircle works on any platform, any content type.
Results
Five honest verdicts.
ClaimCircle never rounds complexity to a simple true/false. Every result names what the evidence actually shows.
Supported
Supported, but misleading
Contradicted
Limited support
Unclear
Privacy guardrails
Built to stay out of your way.
ClaimCircle is designed with tight boundaries on what it can even see, let alone share.

No background scanning
The extension never reads a page unless you draw a circle. It watches mouse coordinates only, with no page context until you trigger a check.
Sensitive fields refused
Checks that intersect password, email, phone, payment, or editable form regions are automatically blocked.
Only the circled region is sent
The backend receives only the text and image metadata from the specific region you circled — nothing else from the page.
No payment card numbers stored
Billing is handled entirely by Paddle. ClaimCircle never receives or stores your full payment card number.
Pricing
Free to try, honest about limits.

ClaimCircle is an evidence aid, not a truth oracle. It helps you slow down, compare sources, and decide whether a claim deserves trust.
