SigmaNote

SigmaNote is an AI-powered tool designed to transform any file, link, or video into editable, searchable, and chat-enabled notes. It functions as a 'Second Brain' by allowing users to capture diverse content, convert it into clean, AI-ready Markdown notes, and then interact with these notes through search, chat, and organization features. The platform aims to help users efficiently capture, convert, and remember information, providing a unified workspace for raw sources, personal notes, and AI chat.

To use SigmaNote, users can capture content by sharing a PDF, pasting a URL, or utilizing the built-in editor. The app then converts the content into editable Markdown notes with a single tap, while keeping the original file viewable. Users can then chat with their notes to ask follow-up questions, get summaries, brainstorm ideas, or cross-reference old notes. Notes can be organized into 'spaces' (folders) for easy management.
