AI output looks fine in the chat window — and then breaks everything else. ChatGPT, Claude, Gemini and Copilot all produce typographic smart quotes (" "), em dashes (—), non-breaking spaces, and sometimes hidden Unicode that causes encoding errors in CMS platforms, databases, and email clients. Deep Clean mode is pre-selected to catch it all.

Why AI Text Needs Cleaning Before You Paste
Large language models output typographically rich text: smart quotes, curly apostrophes, em dashes, ellipsis characters, and sometimes invisible formatting. This looks great in the chat interface but causes real problems in Notion, WordPress, Webflow, HubSpot, Salesforce, email clients, and anywhere that processes text programmatically.
Deep Clean mode runs all three cleaning layers: normalizes special characters, strips hidden Unicode, and collapses extra whitespace — exactly what you need after copying from a language model.
