Questions
About this tool
Is it really free?
Yes. The full answer on screen is free, as often as fair use allows. You need an email only to keep, export, share or watch a result.
Is the answer advice?
No. Every result shows its factors and where they come from, so you can check it. Treat it as a well-prepared starting point, not a ruling.
What happens to my data?
No account needed. What you upload is deleted within a day (voice within 15 minutes), is never used to train a model, and nothing you did not type is kept.
