When composing a message, you can highlight any text and use AI to transform it instantly — make it longer, shorter, friendlier, more motivational, or fix grammar.


How to Use It

  1. Type your message in the composer

  2. Highlight the text you want to transform (select with mouse or keyboard)

  3. A floating toolbar appears near your selection with 8 AI options

  4. Click any option — the AI rewrites the selected text and replaces it


Available AI Text Tools

Tool

What It Does

Expand

Makes the text longer with more detail

Improve

General improvement — better wording and flow

Tips

  • Select specific sections — you don't have to select the entire message. Highlight just the sentence or paragraph you want to transform.

  • Chain transformations — expand first, then make it more concise. Or improve, then match your voice.

  • Undo — if you don't like the result, press Cmd+Z (Mac) / Ctrl+Z (Windows) to undo

  • "Match Voice" gets better over time — the more messages you send, the better the AI understands your coaching style


Where It Works

The AI text tools appear in the message composer on the Trainerize Messages page and in the Conversation Dock. They work in both Reply mode and Note mode.
