To-do apps that work with ChatGPT and Claude
You tell the assistant “add ‘Call the dentist’ to Thursday”, and the task shows up in your to-do app on the web and on your phone. These apps do it with an official ChatGPT app, a Claude connector or their own MCP server.

The short list
| App | What it is | ChatGPT app | Claude connector | MCP server |
|---|---|---|---|---|
| Tweek | Weekly planner and to-do list, the week on one page | Yes | Yes | Yes |
| Todoist | Task lists and projects with natural-language dates | Yes | Yes | Yes |
| TickTick | Tasks, calendar, habits and a focus timer | Yes | Yes | Yes |
| Asana | Work management for teams | Yes | Yes | Yes |
| Notion | Notes, docs and databases, tasks among them | Yes | Yes | Yes |
Each of these apps has a free plan. Apps in ChatGPT and connectors in Claude depend on the assistant’s own plan.
Which one fits
- Tweek if you plan by the week. Monday to Sunday sit side by side, like a paper planner, and tasks with no day yet wait in Someday lists. Ask “What’s on my week?” or “Move everything I didn’t finish to Friday”.
- Todoist if you keep long lists and projects and like typing dates the way you say them.
- TickTick if you want habits, a calendar and a Pomodoro timer in the same app as your tasks.
- Asana if the tasks belong to a team project with owners and deadlines.
- Notion if your tasks live next to notes and documents in one workspace.
Tweek with ChatGPT and Claude

- “Plan my week: gym on Tuesday and Thursday, dentist on Friday at 10:00.”
- “Put ‘Renew passport’ on my someday list.”
- “Mark ‘Buy milk’ as done.”
- “Add ‘Standup’ every weekday at 9:30 with a reminder.” (Premium)
Set it up: ChatGPT, Claude, or any MCP client with Tweek MCP.
