Building made me switch from Claude Code to Codex. Claude’s token usage was too expensive for my workflow. GPT-5.6 Sol + Codex lets me focus on building instead of watching usage limits. Loving it so far! 🚀 @OpenAI @thsottiaux

Remove duplicates and clean messy text without uploading your data.
u/PsychologicalCoat976 · Reddit
I got tired of cleaning messy lists manually, so I built a 100% private web tool that runs entirely in your browser Hey everyone! 👋 I constantly found myself wasting time removing duplicates, cleaning up random junk text, and sorting data.
