Manual fact-checking vs. automated real-time verification
Every minute spent manually verifying AI outputs is time taken away from the work the AI was supposed to help with.
Manual fact-checking involves opening multiple tabs, searching for primary sources, reading original documents, and comparing claims — one at a time, after every AI response.
Verol automates this entire process. It sits inside your browser, extracts factual claims from AI responses automatically, and runs deep verification searches in parallel — surfacing results before you act on the information.
Manual verification takes minutes per claim. Verol's automated pipeline takes under 2 seconds — and covers claims you might not have thought to check.
