我提供一个地方来保存时光 欢迎大家来我家分享旅游和生活经历,感觉现在市面上的这种分享旅游和生活的网站都不是我想要的,我自己花了很多时间做了这个,虽然还在优化中,但感觉具体功能是自己想要的。 (行路笔记) https://www.zero2me.com 手机端还在开发中... 不靠这个做商业化,主业不是这个,这个纯粹是个人兴趣,希望能找到一帮志同道合有趣的朋友。

- AI Launching Tool

One global timer. $1 to steal the throne. Hold it when it hits zero and win permanently.

Deciding is the part you can’t delegate. Capture from anywhere, including inside your assistant, and keep one list on web, Windows, Mac, and iPhone.

Done Bear - a local-first task manager with MCP, an API and a CLI Done Bear is a task manager with the five GTD lists, Inbox through Someday, and not much else. https://donebear.com Your AI assistant can use it. A hosted MCP server lets Claude or ChatGPT read your tasks, add them and tick them off, with your permission and nothing running locally. There's a GraphQL API and a CLI too, if you'd rather script it. It runs on the web, Mac, Windows, Linux and iPhone. Tasks live on your device
