Me: [Skeptical that AI assistants do anything useful.] I gave @Muse a try this weekend. It booked me a restaurant and parking reservation. OK whatever, thanks. I asked it to research the best of 700+ episodes of a podcast series that I like. Easy. Thanks again. Then it offered

Disclaimer. This is the first time I've used Muse or VSCode as a harness. The reason I am using VSCode as a harness is this is a research project for my job, and we only have VSCode, Codex, and Claude Code approved for harnesses. I ran it in a folder with only one HTML file (800 lines) that is a Roblox-style COD game. I just gave it a prompt "Can you fix the bugs in the file". It read the file 3 times, found one bug, started to fix it, then got stuck reading the same 10 lines over and over. I imagine it's one of these three issues. • It's a prompt error, being way too vague/open ended for the capabilities of a smaller model. I tried again, with a specific prompt to fix a specific bug, and it still just ends up so confused, trying to grep/find the file despite already having read it, and trying to find the code inside of the file. • It's a limitation of small models running with a large harness/having way too much going on. I tried running it with Pi with its default prompt, and it just got stuck doing tool calls and never actually read the file. Tried running this just directly in the Unsloth Desktop UI with no harness but it failed to parse the file I inputted and tried to gen

Hey just a thank you to Muse and Meta. I fed it pictures of books I want to sell and it researched prices then listed items on eBay with its own computer. My kid hates reading so I asked muse to put together a book about about funny or interesting Starbucks and Sephora product reviews and we read them together. I didn’t know when to show up to a concert to see only the main band and it gave an accurate exact time. It watches my water filter replacement schedule now and pings if action is needed. It watches prices for seasons of TV shows I want to buy from Fandango. I run a Hermes agent for my small business but want a separate agent for personal things. Muse is perfect.

Meta Muse app has been launched. I asked it to do full online research of myself and it created a full portfolio! Included a career timeline, social media platform stats and all of my speaking arrangements. This is a great way for a new agent to learn about you.

I've been using Muse pretty heavily since shortly after it launched, and I'm curious what everyone else is actually doing with it. I've been trying to get past the "ask it a question" stage and use it more like a real personal assistant. So far I've been testing it for things like: - Creating a personalized morning briefing around the news and information I care about - Travel research, bookings and itineraries - Keeping track of projects - Reviewing bills and subscriptions - Researching things and then actually helping me follow through on them The biggest difference I'm noticing is that I'm starting to think less about "what question should I ask AI?" and more about "what do I need to get done?" I'm still figuring out where Muse is genuinely useful versus where it's just AI novelty. For those of you who have been using it for a few days: What's the most useful thing you've actually had Muse DO for you so far? And is there anything you're trying to make it do but haven't figured out yet? I've been testing different workflows almost every day, so I'd be interested in comparing notes. But probably my biggest Muse project so far has been putting together a Muse Tips & T
