Show HN: Magnifying glass effect for your screenshots
I often want to zoom into a specific part of a screenshot to share it with my team, customers, or whoever. I used to use Figma for this, but people would always ask how I did it, and explaining the process in Figma created too much friction. So, I vibe-coded this for myself using v0—115 iterations to get it to where it is now.

Show HN: Vibe-coded a Peter Roberts immigration AI using his HN past AMAs
I saw Peter Robert's AMA on HN yesterday (https://news.ycombinator.com/item?id=43363056) and wondered what would happen if I fine-tuned a model on all of his past answers.I vibe-coded this with Claude Code every time my 8 month old son had a nap today. I also fine-tuned OpenAI GPT-4o mini to power it. Zero lines of code were manually written or modified by me — everything was done by...
Unifying dependency versions across NPM workspaces
The motivation behind this was twofold. Firstly, we're both the type of people who often edit our Slack messages (or any other messages like WhatsApp) to correct mistakes. Secondly, my wife is a PMM at a tech company, but she can't code. I've been telling her that anyone can create a decent product with the help of LLMs and tools like Replit, but she usually just rolls her eyes. So, on a flight from London to SF, I suggested we build Spruce. The idea was that she would take the lead and rely on LLMs (ChatGPT + Ollama for when the wonderful Delta internet wasn't working), and she could also treat me as a [more intelligent] LLM. After ~12 hours and a few small arguments, Spruce was born. :)
Some random learnings, top of mind:
1. A non-technical person, even with current LLMs (GPT 4.5), can't go from idea to shipped product without at least some help from a technical person.
2. I now make even more typos because my habit is to type as fast as possible, often without even pressing the space bar. Spruce autocorrects everything in Slack, but when I'm using other products, I feel incomplete.
3. Although I'm practically a native English speaker, it's still my second language. I've added a feature to Spruce, just for myself for now, that DMs me if I make really obvious grammar/English mistakes in my messages. I decided to do this after one of my colleagues, who is very English, said "for prosperity" instead of "for posterity" in several messages, and another said "for all intensive purposes" instead of "for all intents and purposes." It's been a very cool development, at least for me! It's fun because a) it has a nice tone, and b) it's not verbose and only nudges you on major mistakes, and only up to twice a day. Anyway, feel free to give it a try: https://spruce.so/
P.S. This Slack app necessarily needs the permissions it has because it needs to be able to read and edit your messages everywhere (e.g., public channels, private channels, DMs, etc.). Don't install it if that freaks you out. However, it's easy to remove Slack apps, so there's no harm in giving it a try.

Show HN: Autocorrect for Your Slack Messages
My wife and I built this for ourselves and for a bit of fun. We're both pretty anal about editing our Slack messages to correct typos or grammar errors, so we built Spruce to help with that.

Stop the Slapdash Hiring
Ask HN: Would you find it helpful if candidates rated you, Uber-style?
As an interviewer, imagine if candidates anonymously gave you a rating and answered a few questions about the interview (e.g., did the interviewer give you enough opportunity to shine?).Can you imagine finding this helpful? How do you think you'd feel about it over time?
