Aftertype: Hidden AI Marks

Copy a reply from ChatGPT or Claude and send it to Aftertype from the Share menu. You get a separate screen to check the text before it reaches an email, customer record, document or CMS.

Copied AI text can contain invisible Unicode and unusual spaces. Some control characters can arrive with the text as well. Aftertype lists each supported character it finds. Stray ones are removed from the final copy, while Unicode needed for languages or emoji stays in place.

Keep the original punctuation or change selected marks to the forms you normally use. Dashes, quotes, spaces and ellipses have separate switches. You can also save case-sensitive replacements for words or phrases you change often. Every option is off until you switch it on.

The result stays on screen for review. Copy it and return to the app where you were working.

Aftertype includes:

• Share-in support for plain text
• Automatic checks after paste or share
• A report with character names and counts
• Optional punctuation settings
• Up to 20 saved find-and-replace rules
• Support for text up to 100,000 characters
• On-device cleanup that works offline

Use Aftertype with text copied from ChatGPT, Claude, Gemini, Copilot, a web page or a document.

Your draft is not uploaded for cleanup. Ads and basic analytics may use the network. The words you paste are excluded from analytics and ad requests.

People use "AI watermark" for hidden characters and for statistical signals in wording. Aftertype reports the supported characters it can inspect in copied text and lets you choose visible punctuation changes. It does not erase watermarks from photos or videos. The report is not proof of authorship and comes with no promise about an AI detector score.
