according to — fact-check with real sources

Fact-check any claim on the page you're reading. Rate and prioritise sources — see whether your go-to sources agree.

This is the fact-checking extension that puts you back in the driver's seat! Most tools hand you a verdict and ask to trust it. according to does the opposite: You decide which websites are credible before checking claims. HOW IT WORKS 1. Highlight any claim on a page, right-click, and pick "Fact-check selection." 2. The AI extracts up to three claims from the selection 3. Your claim(s) are send to Serper API, where an AI-free search runs for them 4. The AI interprets what comes back (rating: sourced, no source found, contradicted, not assessable) Please see the accuracy of this and my progress in optimizing it: https://accordingto.app/accuracy.html WHAT YOU CONTROL • Rate the trustworthiness of as many domains as you like — your personal list • Star up to 5 priority sources that get searched directly, so the outlets you trust are always consulted, not just whatever is prioritized by the AI • See up to five sources per claim, each with the exact snippet it was judged on WHAT YOU GET BACK Every check comes back as sourced, contradicted, or no source found — with every source listed and linked so you can read it yourself. You see which sources support the claim, which contradict it, and how much of it they actually settle or don't settle. YOUR HISTORY, YOURS TO KEEP Every check is saved to your Searches tab, inspectable source by source, and downloadable as Excel or PDF whenever you want it. GETTING STARTED 1. Requires a free account 2. Your trust-list is what makes the results yours (and better) 3. 25 checks a month free, 250 on a paid plan 4. Prefer to use your own Anthropic API key?
