Show HN: Free Tools (No Ads) – What Should I Build Next?

Hey HN, I launched FreeUtilityTools.com, a fast, no-login, ad-free collection of 200+ small tools to solve everyday problems. It's a personal project to make simple utilities more accessible — translated into 10+ languages, fast on mobile, and growing every week. Some examples: Text tools: remove duplicate lines, compare text, count characters Number tools: Roman numeral converter, binary converter, percentage calculator Time tools: age calculator, timestamp generator ... and a lot of random useful stuff I'm now trying to figure out what to build next. I'd love your ideas: What utility tool do you wish existed (or was faster/simpler)? What problems do you solve repeatedly that a tiny tool could help with? Any feedback on the site’s UX, performance, or growth approach? Thanks for checking it out — excited to hear what you think or what tools you’d love to see added.
