I spent a year building a DSA learning platform with 111 interactive visualizers. Would love feedback. A few years ago, I failed interviews at Google, Amazon, and Microsoft. The reason was simple: I could code, but I never properly understood Data Structures and Algorithms. I spent almost a year learning DSA after that. During that time, I realized I don't learn by memorizing. I learn by building. And I couldn't find a tool that taught DSA the way I wanted to learn it. So I

Visualize your ideal haircut from front, side, and back angles using AI.

19yr old friend and I made an ai haircut tool! Hey all, my friend and I dropped a haircut visualization tool a few weeks ago to cut down onmiscommunication in the barbershop by generating a photo of you with the cut you want from three angles. We have officially launched now with around 25 users and are trying to get more to try it out! The first generation is free so we’d love as many as possible to try it out if you get a minute! Good luck to all your side projects! subm

Analyzes UI screenshots and provides design audits for AI agents.

the boring internal tool became the product we didn’t start with a saas idea. we were just annoyed that every agent-built UI looked weirdly related. so we made an internal finish gate: real screen references, a design contract, browser checks, and a ban list for generic AI defaults. one developer kept asking why it wasn’t public. eventually we stopped having a good answer. now UIZZE has a few paid users. builder disclosure: it’s mine, $9/mo or $99 lifetime: https://uizze.com current

Design vector graphics with AI text-to-SVG generation and multi-format editing in your browser.

I think I may have finally found a fully free alternative to BoxySVG. I came across this browser-based free SVG editor from svgmaker , and it feels pretty close to Apple Freeform in the way the canvas, grids, snapping, and alignment work. It also lets you edit paths, points, text, colors, shapes etc. Most of the things I used to open BoxySVG for, I can now do in this one—and it’s completely free. Honestly, I wasn’t expecting it to be this capable, especially since most AI image generation

I asked ChatGPT 20 different ways who could fix a half-built app. It never named my company once. I do codebase rescue for founders in exactly that spot, so that one stung. There are already plenty of tools that measure this kind of AI visibility, a CDN even ships one free, so I built mine mostly to see my own number, and it confirmed the bad news: near zero. The measuring turned out to be the easy part. What none of the tools do, and what I actually care about, is the fix: getting the mode

Practice algorithms and coding through interactive challenges powered by AI agents that build and test your code.

Free consumer product, seat-based education product, enterprise assessment product. Same codebase. Is this survivable? Three motions off one core. Students practice free and generate cost, not revenue. Educators pay per seat. Hiring teams are the expensive product and the reason any of it matters. The free tier feeds both paid ones and that's the only thing justifying it. Education is slow, cheap, sticky. Hiring is faster, pricier, and churns the second the role gets filled. Billing got
