See exactly what changed
In Fix mode the result is shown as inline corrections — inserted words are highlighted and removed words are struck through — so you can review every change at a glance rather than guessing what the AI did. Toggle to the clean view or copy the corrected text whenever you’re happy.
How accurate is it, and is my text private?
The result is generated by Anthropic’s Claude AI. It’s excellent for tightening and polishing writing, but AI can miss nuance or occasionally shift meaning — always review before relying on it. Your text is sent over an encrypted connection and is not stored by us; under Anthropic’s commercial terms it is not used to train models and is retained only briefly for safety before deletion.
Frequently asked questions
What’s the difference between Paraphrase and Rewrite?
Paraphrase rewords your text while keeping the same meaning and roughly the same length. Rewrite recasts it in a tone you pick — formal, casual, concise, confident, or friendly.
Is my text stored?
No — it’s processed securely and not stored after your request completes.
Is there a usage limit or a paid plan?
Everyone gets 15 free cloud credits a day, shared across the cloud tools; a rewrite uses 1 credit. For heavier use, Kitolity Pro adds more cloud credits — a one-time $5 pack of 100 that never expire, or 120 a month.
