Hey Everybody! Hope you had a merry christmas Today I had a bit of fun with Claude. Started by scraping YC's startups list, then ran them through OpenAI's embedding service, then UMAP'd the embedding to reduce the dimension to just two coordinates and then just forced Claude to write React that would compile to visualize that. I had fun and I think it's interesting, so take a look! Also note that you won't be able to zoom on mobile (found about this Plotly limitation way too late). If there's interest I can fix this issue by changing plotting libs tomorrow :) Merry christmas

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)

I saw this app youlearn.ai on YC and thought of building it. They are claiming to have 1M+ users with just one feature which is to convert your learning material into summaries, quizzes etc. I gave this a shot and cloned almost most of the features in just 9+ hours of continous vibe coding (with 20% manual though). Now I'm selling this on mvp marketplace. Might probably open source it in future or give it free.

Hi HN, When I was in FAANG, I despised ticketing. I was always the eng that refused to update. Then when I was a tech lead, I had the pain of pinging everyone for updates because they hated it too. Things would go out of date, and then no one would really know if we were on track. We also had little visibility into what the team was doing outside of pinging/standups. So I made an AI that looks at every commit you push and updates tickets for you. It can create tickets if there isn't one, update, leave comments, tag associated commits etc... Basically, it's an "AI Board Babysitter" so…

Hey everyone! We spent the major part of the year preparing an idea we had for the YC application. At last minute, we decided not to go through with YC. I mean, we've had our fair shares of failed startups and this was one of those make it or break it scenarios. We took everything we've ever learned and strived to make an app that we were proud of. We spent so much effort into making this app that we couldn't bear stopping short and applying to Y Combinator. (Mind you, there's nothing wrong with YC.) We didn't want to apply to Y Combinator at the last minute because if we had really gone…

I always find myself frustrated by how many steps I have to take to video chat with someone online. There's always too much software to download and install, and too many accounts to remember. The high-end, high-price Cisco conferencing systems I've used are especially fragile. So I built Vidless in a weekend for myself, and I hope you find it useful too. Just create a room and share the link, and you'll be chatting in seconds. You can invite several people (I haven't really tested a max yet), and chats on Vidless are always private. Enjoy!

http://invincibilitee.com Me and my co-founder submitted an app for YC W11, with a web site that would help college graduates figure out what jobs they could get with their chosen degree. We got a rejection email, and already had this as a back-up idea in case we did get rejected. So in the month between rejection and today, we found a printer, found some graphic designers, and got enough done that we felt comfortable with it as a first iteration. I know there aren't so many non-web app startups on HN, but I thought y'all might like to see how 2 guys rebounded from YC rejection.

Hey HN, I built this tool that maps out every YC company worldwide. You can zoom into cities, explore clusters, and click to see details like batch, location, and website. Why I made it? I thought it’d be fun to visualise it, using the same infrastructure I already use in my other project: FoundersAround Some things I’m still improving: • Improve performance • More filters (industries, stages, etc). Would love your feedback. https://yc.foundersaround.com

I'm running several voice-only virtual coffee events on the Discord server in the URL, only for today. The rules are pretty simple: 1. Wait for the "event" to start (see times at the end) 2. If there are no tables with 1 participant, join any one. 3. If there is a table with 1 participant, join that one. 4. When the event ends, all the voice channels are deleted and you have to wait till the next event starts. I initially wanted to build my own web app but then I realised it would be so much easier to just leverage Discord's infrastructure. I also built a bot in a couple hundred lines of Go…

Hey HN, I’m one of two people working on Hyperscreen AI, an AI that does mock technical interviews with you so you can pass more tech screens. I shut my YC startup down a year ago and had to look for a job afterward. Even though I had interned at and landed multiple FAANG offers out of college, I spent almost 6 months looking for a job after my company failed. I was fortunate enough to get technical screens due to my network, but I failed many of them because I didn’t have anybody to practice with. All of my friends either already had jobs and weren’t looking, or were still working on their…

Hey HN, I'm Aydin, a 13-year-old developer and indie maker looking to improve the world with my small startups. Recently, I built 2 micro SaaS projects. I spent days & weeks coding features, always telling myself that after coding one more feature I was for sure to get traction. This never happened. The reason: I never launched. With IndieReq, you can launch your startup fast and get real user feedback so you know exactly what features to ship and improve. All you have to do is sign up for free, create a feedback board, and share the public link with your users. It's that easy! If you've…
