BackMark

BackMark converts Markdown files into a task management system for human-AI collaboration, treating AI as a first-class team member with dedicated spaces for planning, documentation, and self-review. Tasks are stored as .md files with YAML frontmatter, ensuring future-proofing, Git compatibility, and portability without databases or cloud dependency. Initially a CLI tool, it now includes AI-specific spaces and LokiJS indexing for handling large task lists with sub-10ms queries. It operates 100% offline, features a fast CLI with fuzzy search and interactive Kanban, and ensures data ownership without vendor lock-in.
