The to-do list that
works on itself.
Lume is an AI to-do list with a built-in assistant and a real MCP server. Assign a task to Claude Code or Codex and it gets done in the background — then hands it back for you to check off.
Free to start · no credit card · Mac, iPhone & web
Connects to the tools you already use
Capture it. Assign it. Check it off.
Lume feels like the to-do app you already love — it just doesn’t wait for you anymore.
Capture anywhere
Type it, say it, or tell the assistant. “Remember to invoice Acme Friday” lands titled, scheduled, and filed in the right project.
Assign it to an agent
Hand a task to Claude Code or Codex from your list. It works over MCP in the background and narrates progress into the task.
Review and check off
Finished work returns as “ready for review”. Agents never complete tasks — nothing is done until you say it is.
The workflow, not just the checklist
Lume keeps the calm shape of a to-do app, then adds the missing loop: capture the task, hand it to an agent, review the result.
Your to-dos can delegate themselves
Most apps stop at reminding you. Lume lets you hand a task to an AI coding agent — Claude Code or OpenAI Codex — straight from the list. It picks the work up over MCP, narrates what it’s doing into the task’s timeline, and returns a result tagged ready for review.
Frequently asked questions
What makes Lume an AI to-do list?+
Lume has a chat assistant that creates, searches, schedules, and reorganizes your tasks in plain language — and it can hand tasks to AI agents that do the work. The AI is part of how you manage the list, not a separate feature.
What is the MCP server for?+
MCP (Model Context Protocol) lets AI clients like Claude, Cursor, and Codex talk to Lume directly. With Lume’s built-in MCP server connected, your AI can read your tasks, add new ones, and update them — so your to-do list lives wherever you work.
Can I really assign tasks to Claude Code or Codex?+
Yes. Assign a to-do to Claude Code or OpenAI Codex from the list and the agent works on it in the background, posting progress into the task. It returns the work as “ready for review” — agents never check the box themselves.
Is Lume a good Things 3 alternative?+
If you love the Things 3 design but wish it had AI, Lume keeps the clean, native feel and adds an assistant, MCP, agents, a web app, and a REST API. See our Things 3 alternative page for a full comparison.
How much does Lume cost?+
Lume is free to start with no credit card. A Pro plan unlocks the MCP server, API access, and a larger monthly AI credit allowance.
