Finally, a Spreadsheet That's Actually on Your Side

The spreadsheet that does the hard part for you

Skip the formula headaches and formatting hassles. Just describe what you need—Sigma handles the rest.

• Formulas without the frustration: Need a SUM, a VLOOKUP, or something you don't even know the name of? Just describe what you want. Sigma writes the formula and puts it in the right place.
• Messy data, cleaned up automatically: Paste in that messy export from your other tool. Sigma cleans it up, fixes the formatting, and makes it actually readable.
• Drop in your Excel files and keep working: Already have Excel files? Just open them here. No converting, no starting over.

Built for AI from day one

Tools like Excel were designed in the 1980s—long before AI existed. When they added AI features later, it showed. The AI feels bolted on because it was.

Sum Pro is different. We designed the entire spreadsheet around Sigma from the beginning. That means Sigma understands your data, knows where to put formulas, and can actually help instead of just answering questions. It's the difference between having an assistant who knows your workspace and one who's visiting for the first time.
