Privacy & Data
Is my content stored on your servers?
No. Your content is only sent to Vercel AI Gateway for processing and is NOT stored on our servers. Your rewriting history is saved locally in your browser using IndexedDB, meaning your data never leaves your device.
What AI model does RewriteFast use?
RewriteFast uses OpenAI's GPT-5-nano model through Vercel AI Gateway. This ensures fast, high-quality rewrites while maintaining security and privacy.
How do I clear my history?
You can clear your rewriting history at any time by clicking the "Clear History" button in the history sidebar. This will delete all locally stored rewrites from your browser. You can also export your history as a JSON backup before clearing it.
Can I access my history from different devices?
Since your history is stored locally in your browser, it's not automatically synced across devices. However, you can export your history as JSON from one device and import it on another device to transfer your data.
Technical Questions
Which browsers are supported?
RewriteFast works best on modern browsers including Chrome, Firefox, Safari, and Edge (latest versions). Mobile browsers are also supported.
Does RewriteFast work offline?
No, an internet connection is required for AI rewriting since the text is processed through Vercel AI Gateway. However, you can still access your saved history offline.
What happens if the rewriting fails?
If a rewrite fails (due to network issues or API errors), RewriteFast will automatically retry the request. You'll see specific error messages explaining what went wrong, and you can try again once the issue is resolved.
Best Practices
Should I review the rewritten content?
Yes, always review and verify rewritten content before publishing or submitting it. While RewriteFast produces high-quality results, you're responsible for ensuring the final content meets your standards and accurately conveys your intended meaning.
Can RewriteFast help avoid plagiarism?
RewriteFast can help paraphrase content, but you should always cite sources appropriately and ensure your use of rewritten content complies with copyright laws and academic integrity policies. The tool is designed to assist with rewording, not to circumvent proper attribution.
Which mode should I use for my content?
Choose the mode based on your audience and purpose:
- Academic papers: Formal mode
- Business emails: Fluent or Formal mode
- Blog posts: Standard or Casual mode
- Marketing copy: Creative mode
- Social media: Casual or Creative mode
