Frequently Asked Questions

How is this different from QuillBot?

This tool uses frontier AI models like GPT-4o and Gemini 2.5 Pro instead of a weaker proprietary model. There are no word limits (QuillBot's free tier caps at 125 words), no signup required, and you control the cost by bringing your own API key.

Is this free?

Yes, the tool itself is completely free. You just need an API key from OpenAI or Google. A typical rewrite costs $0.001–$0.01 depending on the model and text length — far cheaper than any subscription.

What styles are available?

Seven rewriting styles: Standard (natural rewrite), Formal (professional tone), Casual (conversational), Simpler (easier to understand), Shorter (concise version), Expand (more detail), and Academic (scholarly tone with precise language).

Is my text private?

Yes. Everything runs in your browser. Your text goes directly from your browser to the OpenAI or Google API — it never touches our servers. There is no backend. You can view the source code to verify.

How many words can I rewrite?

There is no word limit. Unlike QuillBot's 125-word free tier, you can rewrite as much text as you want. The only limit is the model's context window, which is over 100,000 tokens for most models.

Which model should I use?

GPT-4.1 Nano or Gemini 2.0 Flash for the cheapest rewrites. GPT-4o or Gemini 2.5 Pro for the highest quality. GPT-4.1 Mini and Gemini 2.5 Flash offer a great balance of quality and cost.
