Questions
Is there a free plan?
No plan, but one page is free to test on the site — paste a link and 300 AI users try it in under two minutes, no account or card. The whole flow, sign-up to payment, runs in your AI assistant on a plan. A whole sample report is open too, and within 14 days of a payment the unused share comes back.
Starter or Pro?
Pro has three times the credits, simulations of up to 1,000 people, and comparing two versions (A/B). Both simulate up to 7 days.
What if a simulation fails?
Its credits come back by themselves — also when it cannot use the AI models, or cannot read most of your screens, and runs on built-in rules instead.
Can I get my money back?
For what you have not used: within 14 days of a payment, the unused share comes back, from a button in My space. A report you opened counts as used ($4). See the refund policy.
How do I cancel?
From My space: Manage billing. Your plan stays until the end of the month you paid for, and your credits stay.
Is what I hand over used to train AI?
No. Screen images are deleted after 30 days. See the privacy policy.
