Hey Product Hunt! 👋 After 15+ years of coding, I've worked with countless task managers, but none felt natural when collaborating with AI assistants like Claude or ChatGPT. They're either too rigid, cloud-dependent, or treat AI as an afterthought. The problem I was solving: When "vibe coding" with AI, I needed a way to let my AI assistant plan, document, and review its own work without cluttering my personal task space. Traditional tools force everything into the same bucket, making it messy to separate human thinking from AI planning. Why Markdown? I wanted zero lock-in. Your tasks should be readable in 50 years, work with Git, and be editable in any text editor. No databases, no proprietary formats, just plain .md files with YAML frontmatter. The evolution: Started as a simple CLI for myself, then added AI-specific spaces (ai_plan, ai_notes, ai_documentation, ai_review). Added LokiJS indexing when my task list grew to 1000+ items. Now it handles massive collections with sub-10ms queries. What makes it different: 100% offline & local (no cloud, no telemetry) AI is a first-class team member with dedicated spaces Blazing fast CLI with fuzzy search & interactive Kanban Your data stays yours, forever Built this because I needed it. Hope it helps fellow developers working in the AI era! 🚀
