Guides
Turn a short sentence or phrase into a fuller, more vivid passage — same meaning, same tone, more description and better flow.
How to use it
- Type the sentence or phrase you want expanded into Extra instructions — "the storm was getting worse", "she felt nervous".
- Press Generate.
- Copy the result, or download it as a text file.
What it costs
This tool costs credits — the Generate button shows the exact price live before you run it. Credits reset daily, and a run that fails costs nothing at all.
Does it change the meaning of my sentence?
It shouldn't — the goal is more description and flow around the same idea, not a different one. Review the result to make sure it still says what you meant.
Is what I type sent anywhere?
Yes — the text you type is sent to the AI provider that expands it, because it's part of the prompt. Don't paste anything confidential into it.
