One task, not a chatbot
Describe a calculation and receive one formula. No files, workbook access, history, or general conversation.
Public formula probe / no login
Say the task.Get the formula.
Turn one plain-language spreadsheet need into one Microsoft Excel-compatible formula—with the parts, assumptions, and cautions attached.
Formula desk / input
One task. One formula.
Output sheet / waiting
The result will show its work.
You will get one formula, plain-language parts, assumptions, and a local function check—not a chat transcript.

VISIBLE
Assumptions stay visible
Cell references and version-sensitive functions are called out so you know what to check before relying on the result.
BOUNDED
Explanation can stay local
Paste a formula and the browser identifies functions, nesting, arguments, and common cautions without a model call.
Planned price / no checkout
$5/month for saved formula briefs.
Payment is not open. The current probe stays free and keeps no history. A paid version would add saved briefs and reusable workbook notes—not file upload or a general spreadsheet assistant.
This records one anonymous intent event only. Email for early access.
Formula field notes
COMPARE
SUMIF vs SUMIFS, VLOOKUP vs XLOOKUP
Choose the smallest lookup or conditional-sum pattern that fits the task.
