Neutron is your desktop AI assistant. It can see what’s on your screen, preemptively offer you help, write, summarize, or read from any app. Don't download another Chrome extension or browser, just use Neutron directly in your existing workflow.
I built this cause most AI apps feel trapped in a box. To get a little context, you have to sign in to ten different services—and even then, they still don’t really know what you’re doing right now. If you want their help, you have to remember to loop them in.
Neutron flips that model. It’s a desktop AI assistant that is your computer:
✨ Works everywhere – Chrome, Word, Slack, PDFs… Neutron overlays AI right on top of the apps you already use.
⚡ Preemptive help – Draft, analyze, search. Neutron guesses what you need next so a quick double-tap of “Tab” just does it.
🧩 Simple & seamless – No endless API sign-ins. No browser switch. Just one intelligent layer across your desktop.
We were inspired by Cursor’s magical “Tab to complete” flow—but realized no one has built that same fluid, predictive experience for the entire desktop. That’s what Neutron is: the preemptive AI layer that lives across all your tools, so you can think and build faster without changing your workflow.
Who’s it for? Founders, engineers, researchers, creators—anyone who uses a computer to think and build.
We’ve been using Neutron daily, for scraping websites, transcribing numbers out of PDFs, and even writing email replies.
Neutron is super handy. I like how it proactively helps without me needing to ask. It makes writing, summarizing, and multitasking across apps way smoother. Definitely feels like a true desktop AI copilot.
This is brilliant. Been using it all day. Really helps with day to day work
installing this app on windows instantly started making my mouse freeze every few seconds for some reason. Uninstalling it fixed it. Not sure why it happends
Congrats on the launch, this looks super useful. Excited to see how it grows!
Congrats on the launch! 🎉 I really like the idea of an AI that works across apps without constant setup. The double-tap Tab shortcut feels super intuitive. This looks like a game-changer for daily workflows.
I really like this idea. The best part is not having to jump between different apps just to get things done. Having AI that works everywhere on the desktop feels practical and natural. It saves time, keeps focus, and removes that little stress of switching back and forth. If Neutron can really stay light and fast while doing this, I think a lot of people will find it useful in their daily work.
The “Tab to complete” flow for the whole desktop is smart. I’ve only seen that kind of smooth experience in coding tools before. Bringing it everywhere could make day-to-day work a lot faster and less distracting.
Kind of scary, but will definitely try it out!
Congrats on launch!
That sounds slick! 🚀 Neutron feels like the kind of AI everyone’s been waiting for not just reactive, but actually stepping in to help before you even realize you need it. That’s a real productivity boost.
This is a super cool project, awesome and congrats on building this, cheers!
