Hey HN, we are Alex and Ivan, two developers who’ve spent too many afternoons trying to understand unfamiliar repos. Like most devs, we don’t enjoy wading through dense docs to get up to speed — so we built CodeBoarding to make codebase onboarding a more interactive experience. Last year, I (Alex) was onboarding at a biotech company in the R&D phase applying ML. As you can imagine, when a team of scientists from non CS-background come together, the code gets pretty messy and full of domain-specific quirks. During my time there, I asked a lot of questions, yet when my internship came to an…

Hi HN, As a developer, I much prefer to write code than read other people’s code. But most projects I work on involve other developers so it’s hard to avoid. Often I find it really hard to quickly parse other people’s code so I thought maybe ChatGPT could help. ChatGPT does a really nice job of giving clear explanations when you paste in code and ask it to explain it. But the interface is a bit of a pain to use if you’re using it many times a day. It’s also hard to share explanations with co-workers. So I built whatdoesthiscodedo.com. Just paste your code and get your ChatGPT explanation and…

Hi HN! I've recently been finding productivity in running parallel CLI coding agents(after not believing in them initially). After having to do a ton of git stashing and branch fumbling, I decided I needed to something to more ergonomically run these agents in their own dedicated spaces. I tried a lot of the existing products but they either were too convoluted or flat out didn't work. Some of them also seem to roll their own chat UI which I don't think is the right approach, I wanted to something to lightly wrap my terminal sessions. So I built FleetCode! It uses git worktrees and let's you…

Hey HN, We’re two developers (co-founders) with a team of 20 who got tired of spending hours reviewing PRs, so we built Infinitcode.ai, an AI-powered code reviewer that: - *Summarizes PRs in plain English*: No more deciphering 1,000-line diff jungles - *Catches more than bugs*: Security holes, performance pitfalls, code smells, even typos (yes, we’ll flag “vurnerabilities” and vulnerabilities) - *Zero onboarding*: Works instantly—no “let me learn your codebase for weeks” nonsense. Why we’re posting: We’re in alpha and need brutal honesty. Roast our tool, mock our UI, or tell us why AI will…

Merge▲115We’re 5 founders who’ve collectively done over 250 interviews - everywhere from startups to Big Tech to quant shops. Most of the interviews we’ve done were Leetcode based or tested skills that weren’t used on the job. These days, with AI, assessments still continue to test code output. Meanwhile, at each of our companies, though, PR counts have nearly tripled. Most of us haven’t manually edited a line of code in a year. Our teams are putting more and more emphasis on code and architecture reviews, yet hiring processes haven’t changed whatsoever. Even the AI-assisted ones we’ve done still…
