Extended is a browser overlay that lets you talk to any website and have it change. Behind the scenes, it builds a working Chrome extension, no dev tools, no setup, just natural language.
Hey everyone! I’m Zach, I quit Microsoft AI’s Copilot team two months ago. I’d built 7 Chrome extensions, but every one took me days of pain in dev tools and console logs. And I realized:
Every “agentic browser” is just a bunch of Chrome extensions someone else made for you, with a shiny new name. We’re going from text output to action output to agents using tools, to agents building their own tools, but right now those on-demand tools are slow & unreliable.
Chrome extensions solve this, but are still a nightmare to build, but they shouldn’t be. So I built Extended: A simple browser overlay that lets you talk to any website, and it builds a Chrome extension for you.
If you're a developer: Stop juggling dev tools, consoles, and extension reloads. Extended gives you one unified overlay that talks to your IDE (like Cursor) and sends just the right DOM context. If you're not a developer: Ever wanted to hide spoilers, redesign Pinterest, or turn a lecture into flashcards? Just say it & a chrome extension is automatically made for you to have it done. Extended makes the internet yours.
At the same time: it's powerful, and challenges like prompt injections, page spoofing, and over trust in generated code are really important, especially if we're auto-running code for non-technical users locally. I'm dedicated to doing this responsibly while democratizing this tech, so I'm rolling out via waitlist to do my best to nail it. Would love any advice or your thoughts: https://x.com/ZacharyGoldman_
OMG, blocking sports video spoilers is the one thing I swear I’ll build for myself at least three times a week and then never actually do it. That alone makes this app totally worth it for me! Amazing work!
This is absolutely amazing! As someone who regularly builds Chrome extensions, I can see this becoming my go-to debugging tool. I particularly appreciate the hot reloading and DOM selection features. Does it support existing extensions, though?
This sounds powerful — being able to interact with and modify any website using just natural language is wild. Curious to try it out on a few annoying sites I use daily. Congrats on the launch! 🚀
@naderikladious Thanks so much! Folks have been coming up with some wild examples, love seeing the unlock in people's minds like oh wait I can rethink like every site I go to! Anything top of mind for you I can make sure it supports as I roll out?
@dylan40 Excited to roll it out - if you'd like, let me know if you have specific stuff you'd want to do & I can try to add it to evals during rollout!
Smart to address the security challenges upfront with a waitlist approach. How are you planning to handle code review and validation before auto-installing extensions, especially for sensitive site interactions? @zach_g1
I’d recommend getting a sharp landing page in place before launch to build trust + convert interest. I design Framer sites that do exactly that, happy to help. Let’s connect 🚀

@miki_makhlevich 100%, Extended is for all of those "why haven't they built this feature? Let me just do it myself" moments!

@apexflux Yes! Thanks for the comment - it's great for existing extensions to debug with this hot reloading, dom selection logic!

Looks awesome. Super excited to try this out!!
@edward_jahoda Can't wait for you to see!
Bro, this is perfect.
Been searching for something exactly like this, and you made it! I just added myself to the waitlist, would love to try it Zach!
@dylan40 Excited to roll it out - if you'd like, let me know if you have specific stuff you'd want to do & I can try to add it to evals during rollout!
This is realy creative, didn't even know this was possible
@cagarwal70 Huge compliment! Excited to continue rolling it out soon!
Wow, this is actually so cool!🤩

Extended looks promising, love the positioning.
