Documents

Real documents, edited where you made them

Ask for a report and you get a Word file, not a wall of text to copy out. Ask for an analysis and you get a spreadsheet with the formulas in it. Then you edit it right here.

Output

Produced as files, not as chat

Sigma Domain runs on Claude Code, the same engine behind Claude's software-engineering work. One consequence is that it doesn't just describe a document — it builds the actual file: .docx, .xlsx, .pptx, PDF. Headings, tables of contents, page numbers, working formulas, real slides.

It reads them too. Hand it a contract, a rent roll, a deck or a scanned PDF and ask what's in it, what changed, or what's missing.

Word

Edit a generated or uploaded document in the browser or on your phone, with the formatting intact.

Excel

Adjust the numbers, keep the formulas live, and ask for the analysis to be redone against your changes.

PowerPoint

Rework slides directly, or ask for the deck to be restructured and edit the result.

Afterwards

Then send it wherever it needs to go

The editors are built in, so nothing has to leave Sigma Domain to be changed — which also means the file never has to leave your private storage to be worked on.

Download it, keep it in your account, publish it at a shareable link, or bring it into a conversation with other people and work on it together. A document produced here is an ordinary file: it opens anywhere, and you're not locked into our viewer to use it.
