For teams who build in spreadsheets

AI for Software Development, One Cell at a Time

Most real-world software development happens in cells, not codebases. Biscuit is AI for software development built for Excel and Google Sheets: it writes the formula, explains the logic, and fixes what's broken.

What Biscuit actually does

Software development, translated for spreadsheets

Six things a decent AI coding assistant should do for the language your team already writes in: formulas.

Formula generation from plain English

Describe the result you want in a sentence. Biscuit writes the formula, in Excel or Sheets syntax, ready to paste into the cell.

Formula debugging

Paste a formula that returns #N/A, #REF!, or a wrong number. Biscuit finds the broken argument and explains what changed.

Plain-English explanations

Inherited a spreadsheet built by someone who left the company? Biscuit reads the nested formula and tells you what it actually does.

Excel and Sheets, both covered

Same request, correct syntax either way. Biscuit knows where XLOOKUP works, where it doesn't, and what to use instead.

Context-aware suggestions

Biscuit reads your column headers and sample rows before answering, so the formula it hands back references the right ranges the first time.

No install, no macros to trust

Runs as a sidebar or a chat, not a plugin with edit rights to your workbook. Nothing runs against your data you didn't ask for.

For the ops manager who inherited a workbook nobody documented

Someone built the reporting sheet three managers ago. The formulas still run, mostly, and nobody quite remembers why one cell multiplies by 1.08 or why a lookup jumps to a tab called Copy of Copy of Final. Paste the formula into Biscuit and get a plain answer: what it references, why the 1.08 is there, and what breaks if a column gets inserted to its left.

  • Explains inherited formulas line by line
  • Flags fragile references before you touch them
  • Suggests a safer version without changing the output
  • Points out which cells will break first if the sheet is restructured

For the two-person team without a shared coding standard

Software development inside a growing company usually means two people with different spreadsheet habits trying to agree on one shared file. Biscuit gives both a plain-English answer they can check against the same source, so the formula that lands in the file is the one that got explained, not the one someone half-remembered from a forum thread.

  • One shared answer for both Excel and Sheets
  • Formulas explained in language the whole team understands
  • Works inside the file you already have open
  • No separate style guide to write or enforce

How it works

From a sentence to a working formula in three steps

No prompt syntax to learn. Describe the problem the way you'd describe it to a colleague who happens to know every formula by heart.

  1. 1

    Describe the result

    Type what you want in plain English: total sales by region, excluding refunds. No syntax required.

  2. 2

    Get the formula

    Biscuit returns the formula in the syntax your file already uses, Excel or Sheets, with each argument named.

  3. 3

    Paste and check

    Copy the formula into the cell. If a value looks off, ask Biscuit why, and it walks the logic back with you.

  4. 4

    Fix what breaks later

    Six months later, when the sheet changes shape, paste the formula back in and ask what changed. Biscuit re-reads it against the new columns.

Common questions

Is this an IDE or a coding assistant like GitHub Copilot?
No. Biscuit doesn't write Python or JavaScript. It writes and explains the formulas that run inside Excel and Google Sheets, which is where most business software development actually happens.
Does Biscuit need access to my full workbook?
No. You paste a formula or describe a problem, not your whole file. Biscuit doesn't request edit rights, doesn't install a macro, and doesn't see data you don't share in the chat.
What's the difference between this and asking a general AI chatbot?
A general chatbot doesn't know if you're on Excel 2016 or Google Sheets, and it won't tell you where XLOOKUP silently fails. Biscuit is built specifically for spreadsheet formula syntax, versions included.
Can it fix a formula that returns #REF! or #N/A?
Yes. Paste the formula and describe what it should return. Biscuit traces the broken reference or the missing match and explains the fix in plain English.
Does it work for Google Sheets-only functions like QUERY or ARRAYFORMULA?
Yes. Biscuit knows which functions are Sheets-only, which are Excel-only, and translates between the two when a formula needs to move from one to the other.
Is there a learning curve?
No. You describe the problem the same way you'd ask a colleague. There's no prompt syntax to memorize and no account setup before your first question.
Do I need a paid plan to try it?
No. You can try Biscuit for free directly on formula.dog before deciding if you need anything more.
How does it handle a really long nested formula?
It breaks the formula into its individual functions, evaluates each one in order, and tells you which part produces the value you're seeing. That's usually faster than tracing it by hand, cell reference by cell reference.

Try the AI built for the software development you actually do

Paste a formula, describe a problem, or ask why a cell returns the wrong number. Biscuit reads the logic, not just the syntax, and answers in seconds.
