What is konbu?
konbu is a personal digital planner — a Filofax-style system planner, digitized. A self-hostable Go binary that binds your memos, todos, schedule, and structured tables into one notebook, kept by an AI butler, and surfaces everything from a single search interface. It's yours alone — nothing is ever shared out. Not a replacement for Notion + Todoist + Calendar — a replacement for the act of searching four apps to find one thing.
What's different:
- Native MCP server + CLI client -- Two parallel routes for the AI butler (Claude / Cursor / any MCP client) or shell / scripts to operate your planner.
- Cross-resource full-text search -- One query across memos, todos, events, and structured tables. This is the core UX, not a side feature.
- Structured tables (= table-memo, planned) -- Track blood pressure, household budgets, or inventory. Markdown can't express these; tables can.
- BYOK AI chat -- Bring your own OpenAI/Anthropic API key, or use the included free tier.
- Personal by design -- One notebook, for you only. Pulls in from outside (Google Calendar), never leaks out.
- Self-hostable -- One Go binary, Docker compose, or use the hosted version.
