Why knowledge workers use it

Formula help general AI coding assistants weren't built for

Cursor, Copilot and ChatGPT are excellent at writing whole applications. None of them were designed around the one-off formula request a financial analyst or ops manager actually needs answered in the next two minutes.

Built for formulas, not codebases

No repo to index, no IDE to open. Describe the spreadsheet problem in plain English and get the formula back in seconds.

Excel and Sheets, both covered

VLOOKUP, XLOOKUP, LET, LAMBDA, ARRAYFORMULA, QUERY: Biscuit knows which platform each one belongs to and says so.

SQL and regex too

The same plain-English request that fetches a formula also generates SQL queries and regex patterns when that's the job.

Argument-by-argument explanation

Every formula comes with what each argument does, not just the finished string to paste and hope works.

VBA and Apps Script snippets

Classic macro workflows and Google Apps Script get the same plain-English treatment as regular formulas.

No sign-up for the free tier

Five formulas a day, no account, no credit card. Pay only once you actually need more than that.

The honest trade-off

Formula.dog vs general AI coding assistants

Cursor and Copilot are excellent at writing software. For a single spreadsheet formula, here's what actually differs.

Criteria	Formula.dog	ChatGPT	GitHub Copilot / Cursor
Built for spreadsheet formulas specifically	Yes	No, general assistant	No, code editor assistant
Explains each argument	Yes, always	Sometimes, depends on the prompt	Rarely, focused on code completion
Free tier without sign-up	Yes, 5 a day	Yes, capped and rate-limited	No, account required
Needs an IDE or codebase open	No	No	Yes, lives inside an editor
Covers VBA and Apps Script snippets	Yes	Sometimes	Yes, but as general code
Best for	One formula, fast	General coding questions	Writing and shipping software

How Biscuit fetches a formula

Three steps, no coding assistant required.

1

Describe the problem in plain English

Tell Biscuit what the two columns are and what you're trying to match, sum, or extract. No formula syntax needed to start.
2

Biscuit fetches the formula

Get back a working Excel or Sheets formula, or a VBA or regex snippet, with each argument explained right underneath.

Common questions

Is a general AI coding assistant good at writing Excel formulas?

It can be, but it wasn't built for it. Tools like Copilot or Cursor are tuned for reading and writing whole codebases, so a one-off VLOOKUP or QUERY request gets treated as a side task, not the main job.

Can ChatGPT write a VLOOKUP or XLOOKUP formula?

Usually yes, though it doesn't always specify whether the answer works in Excel, Google Sheets, or both. Formula.dog answers that question by default, every time.

What's the real difference between Formula.dog and a general AI coding assistant?

A coding assistant is built to help you write and ship software across a whole project. Formula.dog is built for one job: turn a plain-English spreadsheet problem into a working formula, fast.

Does Formula.dog write VBA macros and Google Apps Script?

Yes. Classic VBA snippets and Apps Script get the same plain-English treatment as Excel and Sheets formulas, argument by argument.

Can it generate SQL queries too?

Yes, for straightforward queries. Describe what you need to pull or join and Biscuit fetches the query, though deep schema work still benefits from a general coding assistant.

Is Formula.dog free to use?

The free tier covers 5 formulas a day with no account required. A one-time pack of 100 or an $8 a month unlimited plan cover heavier use.

Does it work for Airtable or Notion formulas?

Basic support exists for both. Excel and Google Sheets remain the most complete, with VBA, Apps Script, SQL and regex covered as well.

Why not just ask my existing AI coding assistant for the formula?

You can, and it will often get there eventually. Formula.dog exists for the moments that's slower than it should be: no repo to index, no chat history to scroll, just the formula and what each part of it does.
