Practice system design by submitting architectures and experiencing AI-triggered production incidents.
u/No-Preference-846 · Reddit
I built an AI-augmented system design practice tool that triggers a live production incident when you submit your design - not just a critique Every system design prep resource I used was static — read a diagram, read the tradeoffs, move to the next one. Nothing ever pushed back on what I actually built. So I built ChaosBench . You design a system on a canvas — drag components, wire them up — and when you submit it, an LLM (Gemini) finds the actual weak point in your specific design and
Free AI tutor for kids aged 7-9 that personalizes lessons in coding and technology through interactive games.
u/Designer_Process_715 · Reddit
I built a free AI tutor for kids that remembers each kid and makes learning feel like a game I'm a software engineer and dad of three. My two older kids were deep in YouTube Shorts and Roblox, and I didn't mind the screen — I minded that they walked away with nothing. So over the last ~7 months I built the thing I wished existed. It's called Aivie Spark. My favorite moment testing it: my son hit a Boss Challenge on a math topic and got stuck. Instead of giving up — or getting the answer

Most founders skip validation and pray. I automated the "worth building?" check. AI scans competitors, Reddit, and market data → Cook or Kill in 90 seconds. Killed? It surfaces the pivot the data actually backs.

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
