Show HN: Mutable.ai Codebase chat that uses a Wiki for RAG

[oshams]

Hi HN!

We wanted to introduce our codebase chat that uses a wiki of your repo to do retrieval instead of traditional vector or keyword RAG.

We have been pleasantly surprised by the quality of responses. We think creating a language knowledge base for LLMs to do RAG is the future. The way this works is we first write a Wikipedia style article on your codebase complete with diagrams and citations to your code.

We’ve run it on some of the most popular repos. If you want us to run in an open source repo please comment below. You can also run it on private repos and the permissions will follow those of the repository on GitHub. The wikis auto update via a GitHub bot and even show you previews of the new wikis in a diff view.

Please check it out and let us know your thoughts.

Thank you! Omar

Looks neat. Can you generate on some of my repos (since when I tried it says to contact):

https://github.com/theogravity/loglayer

https://github.com/theogravity/electron-dl-manager

(Really interested in how it works with this one since it's a monorepo)

[oshams]

yep!

I wanted to try mutable.ai on my open-source project one month ago. I contacted info@ but I still haven't got any response.

The repo is https://github.com/laurentlb/shader-minifier and I'm curious to see how well it works with F#.

[oshams]

generating!

[karolist]

This is pretty cool, congrats on the launch. Could you run it on Blender? https://github.com/blender/blender

[oshams]

sure thing, running it now!

[andrewnc]

Hey this is great! How long does it take to generate the Wiki when setting up, and what have you found is the best way to keep it up to date?

[oshams]

it takes a few hours but we're adding parallelization so it takes only a few minutes for typical repos

for it to stay up to date simply have an active subscription and we'll take care of the rest!

Please don't request email address when authorizing using github auth. This invariably leads to spam, either intentionally, or accidentally when services don't guard their database / email sending. Instead make this optional and if not entered prompt me to provide an email address once signed up (and do the right email confirmation dance as needed).

[oshams]

Thanks for the suggestion but we need to alert our users of important changes!

[joshka]

Then ask for an email address for that purpose... in your app... for your app...

[codetrotter]

Looking at the diagrams of one of your provided examples, https://wiki.mutable.ai/deepfakes/faceswap I think there is room for improvement

I don’t feel that any of those diagrams would really help me if my goal is to dive into that codebase

[jdross]

i agreed with you but the chat is what shines. gave me SOTA answers to how i should solve a set of tickets and problems i was interested in on my codebase

[oshams]

have you tried the chat?

[tannercollin]

This is really impressive! Would you mind running it on:

https://github.com/Protospace/spaceport

This is a member portal for my local makerspace. Having a knowledge base will help other makerspace members contribute to the code.

[johtso]

Any chance you could run this on the Effect codebase? Definitely an example of a project that can be hard to navigate due to its scope and gaps in documentation

https://github.com/Effect-TS/effect

[johtso]

Oh I see it's already done! Is it possible to update it to the latest and greatest version? I have to say, the chat responses are quite impressive so far. The linking to relevant sections of code or documentation not so much. I guess that's a pretty hard problem.

[oshams]

yeah on it!

[terencezl]

I like the chat interface. It's more dedicated than the universal archival list of past conversations on Anthropic & ChatGPT. Repo is a good unit of work in a developer's mental model. I tried a few chats and answers have been concise.

Are you using gpt4?
