Questions
Is it really free?
Yes — 5 formulas a day, no account needed. Sigline Pro ($39 one-time) unlocks unlimited formulas, plus everything in Sigline Pro: no branding on your signatures, the animated handwritten name, 2 premium templates, and team invite links.
How do I write a good request?
Say what you want in plain words and name the columns or cells. For example: “Sum sales in column B where column A is Paid” or “Look up the price for the code in A2 from the table in E2:F50.” The more specific the columns, the better the formula.
What if it can't understand my request?
The built-in engine handles the most common formulas — sums, counts, averages, lookups, dates, text and combining cells. Anything beyond that goes to AI mode when it's connected. Until then, try rephrasing with the columns and the condition spelled out, or pick one of the examples.
Is my spreadsheet data private?
Your spreadsheet never leaves your computer — only the sentence you type is sent to our server to build the formula. In AI mode that sentence is also sent to the AI provider to generate the formula. We don't store your prompts.
