"Istinomer Proveri me!" is a browser extension that aids in identifying falsehoods and misuse of facts in statements made by politicians and public officials. Developed by Istinomer, this Chrome add-on enhances the browsing experience for users of popular Serbian news portals such as Blic, Večernje novosti, B92, Kurir, N1, Danas, and Telegraf.

Once installed, "Proveri me!" visually highlights statements that Istinomer has evaluated as true or false, assisting readers in distinguishing between accurate and misleading information. Additionally, users can select a politician's statement they doubt for its truthfulness or consistency and easily submit it to the Istinomer team for fact-checking.
