I built this because of a small, repeated annoyance. Every time I pasted ChatGPT or Claude output into a document, I'd spend a minute stripping em dashes, curly quotes, leftover Markdown, and the occasional invisible character that quietly breaks a CSV import or an exact-match search. So I made 16 tools that each do exactly one of those jobs: • AI Text Cleaner — strips Markdown, normalizes quotes and dashes, removes hidden characters in one pass • Invisible Character Remover — shows every zero-width space and directional mark in place, with its Unicode code point • ChatGPT Export Viewer — drop in conversations.json from your export and read or download individual chats • Markdown → Word, Markdown table → Excel, JSON → CSV, CSV → Markdown • Transcript timestamp remover, prompt splitter, text anonymizer, and more The design constraint I actually care about: everything runs in the browser. The site is static files. There's no server-side processing, no account, and nothing you paste is uploaded. That's not a privacy policy that could change next quarter — there's nowhere for the text to go. Open DevTools and the network panel stays empty while you work. One thing I learned building the invisible-character tool: the common belief that AI models watermark output with zero-width characters doesn't hold up. Generate the same answer twice and the invisible characters don't form a stable pattern. They're almost always non-breaking spaces the *browser* adds when you copy from the chat UI. I wrote up the full breakdown here: https://tidyoutput.com/invisible... It's free and will stay free. Happy to answer anything, and the roadmap is basically "whatever people keep asking for" — so tell me what's missing.
