Xiryn
Running an agent locally is the part that gets me. Most of the agent hype right now lives in the cloud, where your prompts and your files end up on someone else's server. Xiryn flips that, and for anyone who has ever hesitated to hand a chatbot their whole desktop, that alone is worth a look.
The catch is that local agents have a long history of being demos. They can read your screen, maybe click a button, then fall apart on anything messy. I'd want to know what Xiryn actually does well, whether it hooks into real workflows or just answers questions about your files. Open source helps, since you can check the code and see how much it can touch, but that also means the burden is on you to vet it.
I think the timing is right. People are getting pickier about where their data goes, and a capable agent that stays on your machine could carve out a real niche. The question is whether it can be reliable enough to trust with actual work, not just demos.
