App Description
SigmaNote — AI-Powered Knowledge Hub
SigmaNote lets you build your own AI-powered knowledge hub — a single place to capture, manage, learn from, and create knowledge.
It goes beyond notes or chat.
SigmaNote gives you AI agents that work with your knowledge, across every format.
Capture Knowledge from Anywhere
Bring knowledge into SigmaNote from any source:
• Notes and markdown documents
• PDFs, files, and document scans
• Images with OCR
• Web pages and web archives
• YouTube videos (with or without subtitles)
• Voice recordings and system audio
• Real-time, multi-language transcripts
No format limits. Everything becomes searchable and usable.
AI Agents That Organize for You
SigmaNote’s AI agents help you:
• Find relevant knowledge instantly
• Organize content into the right Spaces
• Connect related ideas across files and formats
• Reduce clutter as your knowledge grows
Your knowledge hub stays structured — without manual effort.
Learn by Listening, Reading, and Conversation
Knowledge shouldn’t just sit there.
With SigmaNote, AI agents can:
• Proactively read or speak knowledge to you
• Explain complex topics in simple terms
• Answer questions grounded in your materials
• Help you think through ideas step by step
It’s like discussing your knowledge with a personal tutor or teammate.
Talk to Write. Build New Knowledge.
SigmaNote introduces voice-driven AI writing.
You can talk to an AI agent to:
• Write new documents
• Edit and update markdown files
• Refine ideas through conversation
• Create knowledge using your entire hub or a selected document
This turns thinking out loud into structured writing — powered by everything you’ve learned.
From Capture to Creation
SigmaNote supports the full knowledge lifecycle:
• Capture information
• Understand it with AI
• Absorb it through reading and listening
• Create new knowledge by talking and writing
All in one personal system.
Who It’s For
Students, researchers, founders, consultants, lawyers, clinicians, creators — anyone who wants to own their knowledge and build with it.
Why SigmaNote
• One hub for all knowledge formats
• AI agents grounded in your data
• Learn by conversation, not just reading
• Turn knowledge into output
