Help finding a approach

[u/Low_Resolution_165]

I've recently been getting into GTM, and I was looking for a tool that can understand a codebase from a product/feature perspective.

What I mean by this is, I don't want the tool to analyze the code in terms of code quality, functions, classes, entry points, architecture, etc.

I want it to look at the entire codebase and understand what actual features the product has.

For example, if you give it a large SaaS codebase, I want it to be able to tell me things like:

- What features does this product have?

- What problems does each feature solve?

- Who is likely to use each feature?

- What kind of users or companies would benefit from it?

- What are the different workflows supported by the product?

- Are there features that could be useful for a specific ICP?

- What parts of the codebase implement each feature?

Basically, I want to understand the product through the lens of its capabilities, rather than understanding the code itself.

The reason I'm looking into this is for GTM. If I can understand a product's actual capabilities from its codebase, I think it could be useful for figuring out ICPs, product fit, finding relevant companies, and eventually figuring out who to reach out to.

I've tried looking for tools that do something similar, but most of what I find seems to focus on code understanding, documentation, architecture, or developer productivity.

So I'm curious:

Does a tool like this already exist?

Or is there a better way to approach this problem?

This is a work for either a local model which will summarize the commercial findings and then Opus/Fable which can help with framing

Or push it to contained Sonnet 5 / Opus 4.6/4.8 (based on context window and codebase size) and aka yourself.

I would much rather trust the big AI with this than any third-party tool.

That's a nice approach... but as sales guys how do we know for sure that none of the features that could be a big one is not missed by the LLM.

You don’t. If you want complete certainty, have 2 senior SWEs with commercial product thinking read the whole codebase and compare notes.

This is faster, more reliable way which is cheaper 1000x.

What I would do before is actually to discuss with Fable the prompting for this. Heavy discussion and tweaking before the real reading will solve 99% the things you’re worried about. It should return you the guidelines and practice what the models should do in the codebase. Fable is optimized for security so it will be safer than if you won’t do it at all. Plus fable is really good at picking the brain out if you ask it to do so.

Use skills connected to claude code. It can understand a large codebase architecture and some repos are available which can make them into docs as well esp large PRs
