The project file you'll
never be locked out of.
Free, AI-ready project management in a plain .md file you own outright. No account. No server. No vendor.
No sign-up. No credit card. Your data stays on your device or in your chosen cloud provider.
Chartdown is a competitor to the idea that you need a SaaS tool at all.
What it looks like
Every view. One file.
Board / Kanban view
Visual project phases with tasks, owners, and milestones. Drag tasks between phases as work progresses.
Gantt chart
Timeline view with phases, task dependencies, and critical path — automatically derived from your project file.
Risk matrix
Likelihood × impact grid. Every risk plotted visually, with owner and mitigation stored in the same file.
RACI management
Project and task-level accountability. Every stakeholder, every role, in one clean matrix.
Notes & decision log
Capture the "why" behind every decision. Searchable, Markdown-formatted, and stored in the same file as your tasks.
Mobile & tablet
Full project management on tablet and phone. Your .md file syncs via iCloud, Google Drive or OneDrive — pick up where you left off on any device.
The AI angle
Native, not bolted on.
Your project file is structured Markdown — the ideal input for any LLM. Hit ✦ Copy for AI, pick a template, and Chartdown copies your prompt + full project file to clipboard. Paste into Claude, ChatGPT, or any AI. No API key. No integration. No paid add-on.
