Will it keep my links and formatting intact?

Turn on the preserve toggles for links, Markdown and code and the model is explicitly instructed not to alter them; the diff view lets you verify before you use the result.

What does 'humanise' mode do?

It rewrites to reduce repetitive, overly uniform phrasing often associated with raw AI output — varying sentence length and word choice — without changing the meaning.

Can I keep the same approximate length?

Yes, set the keep-length target and the model aims to stay within a similar word count instead of expanding or shortening.

Do I need my own API key?

Only if the site's shared key is unavailable or its daily cap is used up. Otherwise your own key stays in your browser and talks directly to the provider.

Is my original text stored anywhere?

No — nothing you paste is saved on our servers; it only exists in your browser tab and in the request sent to the AI provider you chose.

About ai rewriter

AI Rewriter rewrites text to a mode you choose — paraphrase, simplify, expand, shorten, formalise, make casual, humanise, academic, creative, or just fix grammar — while preserving what you tell it to preserve: quotes, numbers, names, links, Markdown or code.

Dial rewrite strength and synonym aggressiveness, target a reading level or tone, translate while rewriting, and see a side-by-side diff of the original against the result so you can confirm nothing important changed.

Like every AI tool here, it runs on your own key or the site's shared pool, and nothing you paste in is ever stored.

2Choose a rewrite mode and strength, then open Advanced for finer control over tone, preservation rules and formatting.
