Where do the facts come from?
Facts are fetched live from the Random Useless Facts API (uselessfacts.jsph.pl). If that is unavailable, a secondary source (catfact.ninja) is tried automatically.
Are the facts accurate?
Facts come from curated, publicly maintained databases. While we cannot guarantee every fact, the sources are regularly reviewed for accuracy and quality.
Is any data sent to a server?
The only network requests made are to the public facts APIs to fetch a random fact. No personal data, inputs, or usage information is transmitted or stored by us.
How many facts are available?
The APIs combined provide thousands of unique facts. Click Generate as many times as you like — each result is fetched fresh.
What if the API is down?
Two independent APIs are tried in sequence. If both fail, a clear error is shown and you can try again. There is no hidden local fallback — all facts are always live.
