Three Sigma

Three Sigma is an AI tool designed to help developers and knowledge workers process documents and extract information quickly. It uses AI to read through documents, answer questions about their content, and show you exactly where in the source material each answer comes from. This makes it useful for anyone who needs to review large volumes of text but wants to save time and understand how conclusions were reached. The tool works with various document formats and aims to cut reading time significantly. It's built for people who want transparency in their AI results, rather than just getting answers without context. The platform is currently free to use, and the team has indicated they're working on adding GPT-4 support, image recognition for documents, and a solo mode similar to ChatGPT.
