Frequently asked questions
What does the proofreader fix?
It fixes spelling, grammar and punctuation errors. You get corrected text and a list of changes to review.
Does it rewrite my style?
No. It is asked to keep your original meaning and voice, rather than rewrite for style. Review the corrections before using them.
Where do my text and key go?
Your text and OpenRouter key pass through our server to OpenRouter for the model request. We do not save your text or key on our side. The key stays in this browser tab unless you choose Remember on this device. OpenRouter and the model provider handle the request under their own data policies.
How much text can I proofread, and what does it cost?
Each request accepts up to 2,000 words and 15,000 characters. You pay through your own OpenRouter key; a full page costs about one cent. Up to 300 changes are shown.
