Search intent
Check if text is likely AI-written
VeriOrigin is built for readers, editors, reviewers, teachers, researchers, and marketplace operators who need a quick AI text checker without moving content into a separate website.
AI detector for Chrome
Run checks from the selected text button, the extension popup, or the browser right-click menu.
AI content detector signals
Review probability, result reliability, short reasoning, and stylistic signals in one compact result panel.
Workflow
Three ways to run an AI check
Highlight text on a page
Select a passage and click the AI? button that appears near the selection.
Check a whole readable page
Right-click the page and choose the VeriOrigin page check from the standard Chrome menu.
Paste text from Docs, Word, or PDF
Copy a passage from editors and documents, paste it into the popup, and run the same probabilistic review.
Borderline second pass
Low-reliability or middle-range results can receive a stricter second review before the final answer is shown.
High-stakes caution
The result should support review, not replace judgment. AI detection is not proof of authorship.
FAQ
AI checker questions
What does VeriOrigin AI Checker check?
The current release checks text content: selected page text, readable page text from the current page, and passages pasted into the extension popup.
Can an AI checker prove that text was written by AI?
No. AI detection is probabilistic and may produce false positives or false negatives. VeriOrigin shows a probability signal and a reliability level.
Does the extension include an API key?
No. The Chrome extension calls a backend over HTTPS. Provider credentials stay server-side and are not included in the extension package.
