Recently I had to work on a project with almost no documentation and some truly cursed functions 😅

I realized I was spending way more time trying to understand the code than actually changing it.

So I started building a small side project called CodeWhispr.

You paste in a code snippet and it breaks down:

• what the code does
• functions/structure
• step-by-step logic
• edge cases
• possible improvements

One interesting thing I noticed:
people testing it mostly use it for onboarding and inherited projects rather than writing new code.

Still a work in progress, but it’s been a really fun project to build.

What’s the worst legacy codebase you’ve ever had to work with?

I inherited a messy legacy codebase a while ago and realized something:

Writing code is often easier than understanding someone else’s code.

Especially when:

• there are no comments,
• function names are vague,
• onboarding docs don’t exist,
• and junior devs are afraid to touch anything.

So I built a small SaaS called CodeWhispr.

You paste a code snippet, and it returns:

• a plain-English summary,
• project structure breakdown,
• step-by-step explanation,
• edge cases,
• and improvement suggestions.

Main goal wasn’t “AI coding”.

It was:
👉 helping developers understand inherited code faster.

A few things I learned while building it:

• Streaming AI responses feels MUCH better UX-wise than waiting for a full response
• AI safety filters randomly block perfectly valid code unless configured carefully
• Most users care more about understanding code than generating it

I also made it privacy-first:

• no code snippets stored server-side
• server-authoritative usage tracking
• rate limiting + atomic DB updates to avoid abuse

Would genuinely appreciate feedback from other SaaS founders/devs:

• Is the positioning clear?
• Would you target junior devs or teams first?
• Is “legacy code understanding” a strong enough niche?

(If anyone wants to try it, I can share the link in the comments.)
