# AI task manager on your list

*Updated 2026-09-22 · Published 2026-09-16 · Matthew Blode*

An AI task feature inside a chatbot is a second list. With Done Bear, ChatGPT and Claude read and add on the list you use on Windows, the web, Mac and iPhone.

> **TL;DR:** A todo feature inside a chatbot gives you a second list to check. Done Bear works on the list you already keep: connect ChatGPT or Claude at the [hosted MCP server](/mcp/clients) and it can read and add tasks there. If you want ChatGPT's own Tasks feature, that's OpenAI's product, and this post isn't about it.

## Two kinds of AI task manager

One kind keeps its todos inside the chatbot. The other is a list you already own, with agents invited onto it. Done Bear is the second kind: agents read and add on the same list you do.

| Criterion           | AI apps with their own todos  | Your list plus agents                            |
| ------------------- | ----------------------------- | ------------------------------------------------ |
| Who owns the list   | Todos live inside the chatbot | Todos live in your task manager                  |
| What the agent does | A second inbox to check       | Agents read and add on the list you already keep |
| Where you open it   | Only in that chat             | One list. Every device.                          |

ChatGPT Tasks is the first column. Done Bear, and Todoist's own MCP connector, are the second.

## ChatGPT Tasks is a different product

ChatGPT Tasks is OpenAI's product, and it lives inside ChatGPT. Stay there if that's the list you wanted.

If your list is already in [Todoist](https://www.todoist.com/help/todoist/todoist-and-ai/connect-todoist-to-an-ai-assistant-xMSzFfHng), Todoist publishes its own MCP connector.

## How ChatGPT and Claude connect

ChatGPT on the web can add a custom MCP app once Developer Mode is on. Paste `https://mcp.donebear.com/mcp` and sign in with OAuth. Free and Plus can't add custom MCP apps.

The [ChatGPT MCP page](/mcp/chatgpt) has the steps and the plan limits. [Claude](/mcp/claude) has its own how-to and connects the same way.

[Start free](/sign-up). No card. Free up to 250 tasks. Current limits are on the [pricing page](/pricing).

## One list on every device

You can't run a week from a list that only exists in one chat. Done Bear keeps the same tasks on [Windows](/windows), web, macOS, Linux, and iOS, so a task you capture on your phone is the one you review on a PC.

There's no Android app yet. The waitlist is on [/android](/android).

The longer comparison is on [Todoist alternatives](/todoist-alternative).
