FAQ Questions, answers, dog.
Not as many as you'd expect. Biscuit likes things short.
01 What exactly does Formula.dog do?
You type what you need in plain English (or any of 12 languages), and Biscuit returns a working Excel or Google Sheets formula, usually with a short explanation. It works for simple stuff like COUNTIF and complicated stuff like nested INDEX/MATCH with XLOOKUP fallbacks. It also writes VBA.
02 Do I need to sign up?
No. The first five formulas every day are free and anonymous. If you want more, you can buy a pack or subscribe, and that's the only time you give us an email.
03 How accurate is it?
Pretty good. On common tasks, the formula works on the first try about 92% of the time. On weird edge cases, Biscuit sometimes needs a rephrase. If a formula fails, you can tell him what went wrong and he'll adjust.
04 Does it work with Google Sheets?
Yes. About half the traffic is Google Sheets users. Biscuit knows ARRAYFORMULA, QUERY, REGEXEXTRACT, FILTER, and all the Sheets-specific functions.
05 Can it write VBA?
Yes. Not huge complex add-ins, but any reasonable macro (loop through rows, format cells, open files, etc). If the VBA is over 50 lines, he'll ask if you really want it.
06 Is my data private?
Yes. Your prompt and the formula are stored for 30 days so you can reuse them from history. Then they're deleted. They are not used to train any model. They are not shared with anyone.
07 Why the dog?
Spreadsheets are stressful. Dogs are calming. Also, the domain was available and cheap.
08 Is this just ChatGPT?
No. Biscuit is a fine-tuned model trained on a dataset of real Excel/Sheets formulas paired with plain-English descriptions. He is faster, more accurate, and less likely to invent fake function names. Also, ChatGPT charges you $20/month. Biscuit charges you $5 once.
09 Do you offer a free trial?
Every day gives you 5 free formulas with no account. That's more of a free ongoing bowl than a trial.
10 Who built this?
One person in Lisbon, plus Biscuit (imaginary). See the about page.
