What it takes off your plate

The work an AI assistant should actually do

Most of the working day is small, repetitive requests. Formulas are one of the most repetitive, and one of the easiest to hand off.

Plain English in, formula out

Say what the columns contain and what you want back. No syntax to remember, no forum thread to dig through.

Excel and Sheets, both

VLOOKUP, XLOOKUP, LET, LAMBDA, ARRAYFORMULA, QUERY. Biscuit tells you which platform each one belongs to.

Every argument explained

You get the formula and a short breakdown of each part, so you can fix it yourself next time something changes.

VBA and regex helpers

Classic macro snippets and regex patterns get the same plain-English treatment as ordinary formulas.

Built for the next two minutes

No project to set up and no chat history to scroll. You have a deadline, you ask, you paste, you move on.

Free tier, no sign-up

Five formulas a day with no account and no credit card. Pay only if your workload outgrows that.

Use case: reporting

Month-end reports without the formula hunt

Finance and ops teams rebuild the same lookups, sums and date calculations every month. Describe the layout once, get the formula, and reuse it. When the sheet changes shape, ask again and Biscuit adjusts it for the new layout. The time you save goes to the analysis, not the syntax.

Sum by month, region or owner

Use case: small teams

One shared sheet, fewer interruptions

In most teams, one person is the spreadsheet person, and everyone else interrupts them. An assistant that writes the formula and explains it means colleagues can unblock themselves. The spreadsheet person gets their afternoon back, and the shared file stays readable because every formula comes with its logic spelled out.

How it works

How Biscuit fetches a formula

Three steps, and none of them involve reading documentation.

1

Describe the problem

Tell Biscuit what the columns are and what you want to match, sum or extract. Plain English is enough.
2

Get the formula back

You receive a working Excel or Sheets formula, or a VBA or regex snippet, with each argument explained underneath.
3

Paste it and check

Copy it into your cell and compare the result with a row you can verify by hand. If it is off, say what is wrong and ask again.

Common questions

What is an AI assistant for work?

It is software that takes a plain-English request and does a piece of your job: drafting, summarizing, searching, or calculating. Formula.dog covers one slice of it, the spreadsheet slice, where you describe a problem and get a working Excel or Google Sheets formula back.

Can an AI assistant for work really handle spreadsheet tasks?

Yes, for the formula part. Describe what the columns hold and what you want out of them, and Biscuit returns a formula you can paste into a cell, with each argument explained. You still check the result against your own data, which takes seconds.

Is Formula.dog a replacement for ChatGPT or Copilot?

No. General assistants are good at writing, brainstorming and summarizing. Formula.dog is narrower on purpose: it only does formulas, VBA, regex and similar snippets, and it always says whether the answer works in Excel, Sheets or both.

Do I need an account to try it?

No. The free tier gives you 5 formulas a day with no sign-up and no credit card. Paid options only matter once you hit that cap.

How much does it cost?

Free is $0 with 5 formulas a day. The Pack of 100 is a $5 one-time purchase with no expiry. Unlimited is $8 a month with formula history and bookmarks.

Which spreadsheet tools does it support?

Excel and Google Sheets are fully covered, including LET, LAMBDA, ARRAYFORMULA and QUERY. VBA snippets and regex helpers are included, and basic Airtable and Notion formulas work too.

What does it not do?

It does not write Power Query, Power BI DAX, Python or R. If your daily work lives there, a general assistant is the better fit for that part.

Is my spreadsheet data uploaded?

You describe the problem in words, so you do not have to paste a whole workbook. Share only the column names and a couple of made-up sample values, and keep real client data out of any AI tool unless your company policy allows it.
