What you're using
Formula.dog is a tool that generates spreadsheet formulas from text descriptions. It's run by one person in Lisbon, Portugal, operating as an indie utility.
What we promise
- The tool will work most of the time. Formulas come back within a few seconds of your prompt. Common tasks succeed on the first try about 92% of the time.
- Your first five formulas a day are genuinely free. No hidden catches.
- If you pay, you get what you paid for, within the limits listed on the homepage.
What we don't promise
- That every formula will be correct. You should verify before pasting into production spreadsheets, especially for financial calculations.
- That Biscuit will be available 24/7. Servers sometimes go down. If they do, we fix them.
- That Biscuit understands every edge case. He's still learning some VBA corners and newer Excel 365 functions.
Refunds
- If you bought a pack and it's genuinely broken, write to us through the contact form within 30 days for a full refund.
- If you subscribed and want to cancel, do it from the dashboard. Your subscription runs out at the end of the current period.
Your content
- You own your prompts and the formulas we return. We only store them for 30 days so you can see them in history.
- Don't upload spreadsheet files into the prompt text. We're not set up to accept files.
Acceptable use
Don't use Biscuit to generate formulas for obviously illegal purposes (like calculating tax evasion schemes). Don't try to automate scraping his responses. Don't abuse the free quota with bots.
Liability
Formula.dog is a tool. You are the accountant, analyst, or operator who makes decisions. If a formula is wrong and you use it for something important without checking, that's on you, not on Biscuit.
Maximum liability is whatever you paid us in the last 12 months. For free users, that's zero.
Termination
You can stop using Formula.dog anytime. We can suspend accounts that abuse the service or violate these terms.
Governing law
Portugal. If there's a dispute, Lisbon courts.
Changes
If we change these terms in a meaningful way, we'll email subscribers in advance.
