MathIQ I built mathiq.io with Claude Code because I wanted a way for students struggling with college level maths to see how the problems can be broken down and not as intimidating. Each walkthrough goes from beginning to end and each step has a "why and how?" feature. Anon users get 1 free daily walkthrough powered by Haiku 4.5. Signed in users get 3 free daily walkthroughts powered by Haiku 4.5. Plus users get 5 Opus 4.6 walkthroughs plus 20 Sonnet 4.6. Pro users get 8 Opus/30

Free calculators for DIY home projects like woodworking, decks, concrete, and drywall.
u/CaboWabo55 · Reddit
Built a DIY calculator site in a weekend — betting on "boring tools" over content After my last project (an AI debate platform) got rejected by AdSense for "low value content," I went the opposite direction: no content treadmill, no AI features, no backend. Just genuinely useful calculators. studandslab.com — 10 free calculators for woodworking and home projects (board feet, stair stringers, concrete, drywall). Everything runs client-side, so hosting is free and every visitor costs me $0.
