Three Sigma is an AI research assistant built for documents. It searches across whole folders of files, answers your questions with full transparency into how it reached each answer, and offers a free solo mode if you just want to chat.
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.
No document on hand? A free solo mode works like a normal chat assistant.
