Pino - Fact Checker

The core move is a right-click. Highlight the text you want checked, open the context menu and choose Fact Check with AI, and the result appears in a popup on the page. Nothing opens a new tab, so you keep the article in view while the verdict loads. It's the part that makes the habit stick, because checking a claim costs almost no effort.

Each result leads with a truth percentage, so you can gauge a claim at a glance before reading the detail. It's the fast read that makes misinformation detection practical mid-scroll. Pino ties that score to the Pinocchio idea. A high score keeps the character's nose short, and a low score stretches it, which gives you a fast visual read on how well the claim holds up.

Pino returns more than a label. The popup explains why a claim snags, separates what's supported from what's overstated, and adds the surrounding context a bare verdict would drop. According to the developer, the tool captures context around the selection rather than judging the sentence in isolation.

Every check ends with links to the pages the model leaned on, so you can click through and read the evidence yourself. That matters for anyone who has to defend a conclusion later. A student citing a paper, a reporter filing a story or an analyst writing a brief all need the trail, not just the rating.

The extension handles claims written in languages other than English, which sets it apart from tools that only reason in one tongue. You can check a foreign-language article without translating it first, and the sources it cites come from the same language space.

Pino runs its standard checks on its own backbone, and it also links to Perplexity for heavier research. You bring a Perplexity Pro API key, paste it into settings and switch on Advanced Mode, then run claims through Perplexity's Sonar and Sonar Pro search. The deeper searches bill to your own Perplexity account, not to Pino.

The developer states that only the highlighted text and the page URL are sent for analysis. That's the whole payload. According to the extension's own privacy notes, there's no tracking, no stored search history and no tracking cookies, and any Perplexity API key you add is encrypted and kept on your own machine.
