ChatGPT and Claude
Tap ChatGPT or Claude under Send the rewrite. Each one opens with the rewrite already in the box. A very long rewrite is copied instead, and the chat opens so you can paste it. PromptMaster does not submit the message.
Gemini
Gemini does not accept a link that fills in the message. The Gemini button copies the rewrite and opens Gemini. Paste it into the box.
Every other app
More opens the Android share sheet. That covers Grok, Copilot, Messages, and any other app that accepts shared text. If the phone has no share sheet, the rewrite is copied.
The prompt of the day can be sent the same way without Pro. The rewrite of a draft you graded stays on Pro, together with copy. The score and the named flaws stay free.
