I built Gray Box because I kept capturing ideas, meeting notes, project decisions, and random thoughts—but finding them later was always painful. Existing note-taking tools expected me to organize everything myself, while AI note apps often hid my data behind proprietary formats. Gray Box takes a different approach. • Capture anything in seconds. • Let AI organize it into a cross-linked Markdown knowledge base automatically. • Ask questions and get grounded answers with citations. • Your notes stay local-first and portable — just Markdown files you own. AI can run locally (Ollama) or via your chosen provider. A few design choices I'm particularly proud of: 📄 Plain Markdown storage (no vendor lock-in) 🔒 Immutable inbox so your original notes are never modified 🕸️ Graph-based retrieval with optional semantic search 🤖 Works with any LiteLLM-supported provider (OpenAI, Anthropic, Gemini, Ollama, and more) 🧠 Human-in-the-loop curation tools for fixing AI extraction mistakes I'd genuinely love your feedback — especially from anyone who's tried the "capture now, structure later" approach with other tools Thanks for checking it out! Happy to answer any questions. 🙌
