Melty is the first chat-based code editor. It creates a git commit along with each chat message so it can always stay in sync with you, like a pair programmer.

We launched Melty two weeks ago, and we're already at 4500 stars on github, which makes it one of the fastest growing open source YC repos ever.

### Active Founders

### Charlie Holtz, Founder

Co-founder & CEO at Melty. I previously led growth at Replicate, where I built apps with millions of users, and I was the youngest quantitative dev at a team at Point72 managing a many billion dollar portfolio. I studied cognitive neuroscience at Brown, where I also played Ultimate Frisbee (and met my co-founder, Jackson).



### Jackson de Campos, Founder

I came from the ML infrastructure team at Netflix, where I scaled inference for video understanding models across Netflix’s catalog. Now working on Melty, an open source AI code editor.

[### Melty: Open source AI code editor for 10x engineers](

Hi everyone! We’re Charlie and Jackson. We’re longtime friends who met playing ultimate frisbee at Brown.



[Charlie]( comes from [Replicate]( where he started the Hacker in Residence team and [accidentally struck fear]( into the heart of Hollywood. [Jackson]( comes from Netflix, where he [built machine learning infrastructure]( that picks the artwork you see for your favorite shows.

We’ve used most of the AI coding tools out there, and often ended up copy-pasting code, juggling ten chats for the same task, or committing buggy code that comes back to bite us later. AI has already transformed how we code, but we know it can do a lot more.

So we’re building [Melty]( the first editor that’s aware of what you’re doing from the terminal to GitHub and collaborates with you to write production-ready code.

We’ve been working on Melty for 28 days, and it’s already writing about half of its own code. It can…

_(all demos real-time)_

**Refactor code across files**

[

**Create web apps from scratch**

[

**Navigate large codebases**

[

**Write its own commits**



We’re designing Melty to

*   Help you understand your code better, not worse
*   Watch every change you make, like a pair programmer
*   Learn and adapt to your codebase
*   Integrate with your compiler, terminal, and debugger, as well as tools like Linear and GitHub

Our asks:

1.  Try Melty ([melty.sh]( and tell us what you think. It’s a fork of VS Code, so it’s compatible with all your settings and extensions.
2.  Tell us: what AI coding tools do you use, what do you like about them, and what’s frustrating? [DM Charlie]( or send us an email at [founders@melty.sh](mailto:founders@melty.sh).
