Lucid

What it is

Lucid is an AI-powered fact checker that assesses online content and returns verdicts on credibility. Users can send links, screenshots, or videos and ask whether content is true, worth buying, AI-generated, or a scam. The tool searches for live evidence and weighs it on credibility and consistency, returning one clear word verdict along with sources listed by name. Users can ask follow-up questions, share results as images, and access their check history. The service is available on mobile apps and web beta.

Questions from the bench

What can I check?

You can check links to articles, posts, shops, or websites; screenshots or photos; and video links from TikTok, Instagram, Facebook, YouTube including Shorts, or X. You pick whether to ask if it is true, worth buying, made with AI, or a scam. You can also skip the content and type your own question. Every check costs one credit regardless of type.

How do the verdicts work?

Lucid weighs the number, credibility, and consistency of available sources and returns a single word on a color scale, never a number or percentage. Different checks have different scales: claim checks run from Verified to False, while buying, AI, and scam checks each have their own four-word scale. Strong, consistent evidence earns a confident verdict, while limited or contradictory evidence is flagged honestly.

Is Lucid always right?

No. Lucid weighs the evidence available at the time of the check and gives its verdict on that basis. Where evidence is thin, contested, or simply missing, it says so rather than picking a side.

Can Lucid help me decide whether to buy something?

Yes. Send the product page, the shop, the ad, or a screenshot of it, and ask whether it is worth buying. Lucid checks whether the seller is a real, established business, whether the product is as described, and what independent buyers report about delivery and returns.

Can Lucid tell me if an image or video was made by AI?

It checks for signs of AI and answers from Authentic through to AI, with Inconclusive in between when the signals do not settle it. A video is judged from one of its frames. Some things are genuinely undetectable: an edit made on your own phone, or a well-made face swap, can read as Inconclusive. We would rather say that plainly than overclaim.
