Frequently Asked Questions
What are the different expansion styles?
We offer three expansion styles:
- Descriptive: Adds vivid details, imagery, and sensory language to make your sentences more engaging and visual
- Explanatory: Adds context, reasoning, and clarification to make complex ideas easier to understand
- Narrative: Adds storytelling elements, flow, and narrative structure to create more compelling content
Can I expand multiple sentences at once?
Yes! The tool supports batch processing. Simply enter each sentence on a new line, and the tool will expand them all at once. This is perfect for working with multiple ideas or expanding several short points into detailed paragraphs.
What's the difference between expansion levels?
Moderate (2-3x longer): Adds essential details and context without overwhelming the original message. Good for most use cases.
Detailed (3-5x longer): Significantly expands with comprehensive details, examples, and explanations. Ideal when you need in-depth content or are developing initial ideas into full paragraphs.
Does this tool store my text?
No. Your privacy is our priority. We never store, log, or share your text. Processing happens via secure AI APIs, and the text is immediately discarded after expansion. Your history is saved locally in your browser only (using IndexedDB) and never sent to our servers.
What's the character limit?
You can expand up to 3,000 characters at once. For longer content, we recommend breaking it into smaller chunks and expanding them separately. Your recent expansions are saved in your browser's history for easy reference.
Can I use this for academic or professional writing?
Yes, but always review and edit the expanded content to match your voice and intent. This tool is designed to help you develop your ideas, not to generate content for you. For academic use, check your institution's AI tool policies. The expanded text should serve as a starting point that you refine and make your own.
