How it works
Three AI models. One click.

No switching between tools. No copy-pasting. Omniscient AI runs in your browser and checks facts where you read them.

1

Highlight text or open any article

Select any sentence or paragraph on any web page, or use Full Page Analysis on a complete article. No setup required beyond installing the extension.

2

Three AIs verify independently

ChatGPT, Perplexity (with live web search), and Google Gemini each analyse the claim independently and return their verdict — Supported, Disputed, Mixed, or Opinion.

3

See verdicts, sources & consensus

A consensus score shows how much the AIs agree. Each verdict comes with web sources and citations so you can verify independently. Full Page Analysis scores the entire article 0–100.
