Three Sigma is an AI research and document assistant that lets you upload files and ask questions as if you were working with a personal analyst.
Document search and faster review
It helps you find relevant passages in long texts and reduce time spent reading and extracting key points. According to the team, it can cut the time needed to study documents by up to 90%.
Answers with explanations and sources
Three Sigma focuses on transparency: for each question, it shows how it arrived at the answer and where the information came from. This makes results easier to verify and reduces the “black box” effect.
Q&A across folders and file sets
You can search and ask questions across entire folders or groups of documents, which is useful for:
- Reports and research materials
- Contracts and legal documents
- Internal documentation and knowledge bases
