Private AI that answers from your own documents, on Mac and Windows
Files, folders, PDFs, Word documents, spreadsheets, slides and scans are read and indexed on your own computer rather than uploaded to a third-party service.
Every response cites the underlying file plus the page, slide or sheet it came from, so you can open and verify the passage yourself.
Names, email addresses and phone numbers are hidden before a question leaves your device, and you can view exactly what was masked under each answer.
Use the default Elephas gateway, plug in your own OpenAI, Claude or Gemini API key, or download a local model so answers are generated on your computer with nothing sent.
AI document research that shows you exactly how it found each answer
Point the tool at a folder of files and ask questions across the whole set at once, rather than opening documents one by one.
Whenever it answers, Three Sigma shows you how it reached the answer, so results are verifiable rather than a black box.
Access Three Sigma through a plugin from within an existing ChatGPT account on every plan.
