Make your YC application stand out (Spring 2025 edition)▲13
Every batch, many founders get rejected due to basic application mistakes, missing key criteria that YC partners explicitly look for. We learned this the hard way, which is why we built YC Score. Simply upload your draft PDF or fill out our YC-mirrored form. Our AI analyzes your responses against 25 critical factors that can make or break your application, from technical credentials to market validation. For instance, when YC partner Dalton Caldwell notes that teams with technical founders have "5x better odds," you need to know before submitting. YC Score flags these deal-breakers and shows…

Practice for the YC interview▲20
I've been blown away by speech-to-speech LLMs lately and was looking for a fun little website to build. Enter mock YC interviews. When I first applied to YC, I used iPG (https://jamescun.github.io/iPG/) to practice and get comfortable with the YC-style interview. Spoiler: I ended up getting in. This took me a few hours to go from scratch to production. Would highly suggest playing around with some of the latest products (this uses Vapi.ai/elevenlabs.io)

We built an AI to review your pull requests▲53
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…
