About factjuice

How it works

• 16,000+ topic pages across 15 categories.
• Every page has a button. Click it; AI generates a verifiable fact about that topic.
• Facts persist. Every squeeze adds to the public archive that anyone can read.
• Free, fast, no signup. Daily generation cap keeps it sustainable.

factjuice is an AI-powered fact generator. Every fact you read here was generated on-demand when someone clicked the squeeze button. Once generated, it's saved forever — so the next visitor sees it too.

The site grows organically. Empty topic pages start with zero facts; popular topics accumulate dozens. The corpus is yours to read and explore.

How facts are generated

Each squeeze sends a tight prompt to Claude (Anthropic's AI model). The prompt asks for a single specific, verifiable fact about the topic — no filler, no clickbait, no "Did you know" intros. The fact is then de-duplicated against the existing archive and saved.

Are the facts true?

The vast majority are. AI is generally accurate on well-established topics, but it can occasionally make mistakes. Treat factjuice the way you'd treat any single source — interesting, mostly reliable, worth verifying if it really matters.

Cost & sustainability

Each squeeze costs about $0.0006 in API fees. There's a hard daily spending cap to keep it sustainable. If the cap is hit, the button serves an existing fact from the archive instead.
