Clawdbot
OpenClaw (previously Clawdbot or Moltbot) is a locally installable AI assistant that you can chat with via WhatsApp, Telegram, iMessage, Discord, Slack etc.
It is, without a doubt, a vibe-coded security nightmare.
Installed on your local machine it can be given access to calendars, reminders, your browser, a search engine, an LLM, Spotify, Trello, Things, Spotify, Home Assistant and much more. You choose the name, it's personality, and then start having it act as your robot butler.
I told it I was going on a trip this weekend and asked what I should do. It searched the web and gave me sensible suggestions, offered up tickets to a show as a good evening activity, worked out the total price and even sent me a screenshot of the available seats from ATG Tickets.

But because it's also backed by an LLM, you can tell it to write the code to complete an action it doesn't know how to do. It's running on your machine, so if you want to rename a bunch of files in a particular pattern, Clawdbot can do that by writing and executing a script that does it.
Like I said - security nightmare.
But there's two things of note here:
1. This is mostly the work of one person, with a professional marketing website, documentation, a plugin architecture, tons of supported services - but yet it's a very new project. It exists because AI made it possible for him to try. There's no $50 million venture backed startup here, just some Javascript you run on your own machine.
2. It shows what an assistant that has access to your data can do. When you step out from an LLM being stuck in a browser window, and instead make sure it has all the context needed to remember who you are, what you like, where you go, and what you do. When you give it the tools and the access - just like Google are trying to do and Apple promised - it's pretty compelling and a hint of what's to come.
