About Three Sigma

What the tool does and who it's for

Three Sigma is an advanced AI research assistant designed to interact directly with your document libraries. Unlike standard chatbots, it utilizes semantic search technology to pinpoint specific information across large groups of documents simultaneously. It provides transparent lineage by showing exactly which part of a document contributed to its answer, ensuring accuracy and auditability. The tool also features a 'Solo Mode' for general queries and a dedicated plugin for ChatGPT Plus users, making it a versatile hub for document-heavy workflows in legal, academic, and business research.

Key capabilities

Multi-document Chat: Query entire folders or groups of documents at once rather than one-by-one.

Transparent Lineage: View the exact source and excerpt used to generate every AI response.

Advanced Semantic Search: Locates information based on meaning rather than just keywords.

Solo Mode: Use the AI for general tasks and brainstorming without needing to reference a specific file.

ChatGPT Plugin: Integrate Three Sigma's document retrieval capabilities directly into your ChatGPT account.

Zero-Data Retention Policy: Ensures sensitive enterprise data is not used for training AI models.

OCR Support: Capabilities for analyzing scanned PDFs and images of documents.

Project Folders: Organize documents into thematic groups for more focused AI analysis.
