Fact-check social media posts on Chrome before resharing a viral claim.
Start with one claim from X, Bluesky, Threads, Reddit, a screenshot, a quoted article snippet, or a chat app, then run a FactSentinel first-step evidence check before you repost, quote, forward, or screenshot it.
Start with the claim you are about to amplify.
Viral posts often mix a real event, a cropped screenshot, a quote, an old image, and a link that only supports part of the story. A practical Chrome workflow starts with the specific claim that would travel if you clicked repost or forward.
1. Preserve context
Keep the post text, screenshot, thread position, quoted article snippet, account name, date, linked source, and nearby replies or context.
2. Run FactSentinel
Review verdict, confidence, source links, caveats, reasoning, and model agreement while the post or article is still open in Chrome.
3. Share with care
Open the source trail and decide whether to share, add context, ask for a source, save for later, or stop the claim from traveling further.
Social claims worth checking first.
The best first check is concrete enough to inspect. Do not start with the whole timeline; start with the claim that makes the post persuasive.
Viral posts
- Numbers, dates, quotes, official-sounding claims, or crisis updates.
- Posts with screenshots that hide the original source.
- Thread claims that depend on one linked article or image.
Quoted snippets
- Article screenshots where the headline is doing most of the work.
- Claims copied from a paywalled or cropped article.
- Summaries where a source link points to a different claim.
Chat app claims
- Forwarded claims from group chats or DMs.
- Old links resurfacing as breaking news.
- Claims where the best next move is asking for the original source.
What the check should give you before sharing.
The goal is not to win an argument in the replies. The goal is to slow the share decision long enough to inspect evidence, caveats, source support, and share with care.
Evidence trail
- Source links tied to the exact social claim.
- Caveats when source support is missing, stale, or mismatched.
- Reasoning that can be challenged before you amplify.
First-step signal
- Whether original evidence is reachable.
- Whether the quoted source supports the wording.
- Where a manual check still matters.
Share-with-care action
- Share with source context.
- Ask for the original evidence.
- Do not reshare when the source trail is weak.
