Interactive platform for learning data structures and algorithms with 300+ problems and visualizations.
u/Comfortable-Break-40 · Reddit
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

Create visual maps of IT system architecture that automatically sync with Jira.

Nodl ( Automates visual system architecture maps directly from live Jira sync, so dev teams never have to manually draw outdated diagrams in Lucidchart or Confluence again.

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

Audit AI-built applications for security vulnerabilities and receive proof of findings.

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.
u/Death12th · Reddit
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

Design applications as node graphs and generate prompts for AI code builders.
@KktErich · X
I built this with Grok — try it out: FlowSpec — draw the app as a node graph, fill in the brief, then export a development prompt for Claude Code, Cursor, or a one-shot builder. From graph to prompt, before a single line of code.

Organize thoughts into visual maps that extract key insights and transform them into documents and presentations.

I rebuilt my landing page after 300+ visitors still didn’t understand what my app does. I’ve been building a spatial thinking environment called ThinkSpatial, and one of the hardest parts hasn’t been building the product. It’s been explaining what it is in the first few seconds. The basic idea is simple. You speak or type, and your thinking gets turned into a visual map instead of disappearing into a chat box, doc, or note-taking app. My first landing page was way too focused on showing h
