I built a free in-browser Llama 3 chatbot powered by WebGPU
I spent the last few days building out a nicer ChatGPT-like interface to use Mistral 7B and Llama 3 fully within a browser (no deps and installs). I’ve used the WebLLM project by MLC AI for a while to interact with LLMs in the browser when handling sensitive data but I found their UI quite lacking for serious use so I built a much better interface around WebLLM. I’ve been using it as a therapist and coach. And it’s wonderful knowing that my personal information never leaves my local computer. Should work on Desktop with Chrome or Edge. Other browsers are adding WebGPU support as well - see…
I built a free in-browser Llama 3 chatbot powered by WebGPU launched on May 3, 2024 with 547 votes, #44 of 4,539 launches that month and more than 99% of that year's launches. The site was still online in September 2026, 2 years on.
In plain words
This is a free in-browser chatbot that runs Llama 3 and Mistral 7B locally using WebGPU technology, eliminating the need for installations or external dependencies. Designed for users who want to interact with large language models while keeping sensitive data on their own computer, it offers a ChatGPT-like interface built on the WebLLM project. The application works on Chrome and Edge desktop browsers, with model files cached locally after the first download for faster subsequent access.

I made an app to use local AI as daily driver2024 · recurse.chat · ▲637Hi Hackers, Excited to share a macOS app I've been working on: https://recurse.chat/ for chatting with local AI. While it's amazing that you can run AI models locally quite easily these days (through llama.cpp / llamafile / ollama / llm CLI etc.), I missed feature complete chat interfaces. Tools like LMStudio are super powerful, but there's a learning curve to it. I'd like to hit a middleground of simplicity and customizability for advanced users. Here's what separates RecurseChat out from similar apps: - UX designed for you to use local AI as a daily driver.…
