Guides
A clear, engaging topic sentence for a paragraph — the opening line that introduces the main idea — with a brief note on why it fits.
How to use it
- Describe the paragraph's subject in Extra instructions — what it's about and what point it's making.
- 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.
Is what I type sent anywhere?
Yes — the text you type is sent to the AI provider that writes the topic sentence, because it's part of the prompt. Don't paste anything confidential into it.
