Three Sigma

What is Three Sigma?
Three Sigma is a document research assistant that answers questions across the files you upload. Point it at PDFs, Word documents, or PowerPoint decks and ask follow-ups in plain language instead of skimming page by page.
What sets it apart is transparency. When you ask a question, Three Sigma shows how it reached the answer rather than hiding the reasoning behind a black box. You can also query entire folders at once, which helps when a project spans annual reports, spreadsheets, and slide decks.
It is built for people who live in long documents: analysts reviewing filings, researchers pulling facts from reports, and teams that need quick, traceable answers from their own files. A ChatGPT plugin and a solo chat mode extend the same workflow into OpenAI and everyday Q&A.
