Google just quietly dropped one of its best AI tools yet.. and almost nobody is talking about it.

it's called CodeWiki.. and it turns any GitHub repo into a fully interactive guide.
just upload an open-source repo and it generates:
→ step-by-step demos
→ visual walkthroughs
→ flowcharts of the entire codebase
→ an AI chatbot that answers questions about the code
→ documentation that actually makes sense
think of it like GitHub on steroids.
you know that feeling when you find a cool open-source project but spend 3 hours just trying to understand the folder structure? that's dead now.
CodeWiki reads the entire repo and breaks it down like a senior engineer explaining it to you over coffee.
I tested it on a 4K+ line codebase and it mapped out the architecture in minutes.. something that would've taken me a full afternoon manually.
this is one of those tools you bookmark and use every week.
stop digging through code repos. let the AI read it for you.
