Write like yourself —
with proof behind every edit
Get evidence-backed feedback that improves your draft without rewriting it.
How Thanis is Different
Other writing AI tools rewrite your text. Thanis flags issues and proposes fixes.
No Generation
Thanis doesn't write content for you. It reviews your draft and suggests edits.
No AI Training
Your text is never used to train AI models, whether or not you have an account.
No Auto Rewrites
Nothing changes automatically. You accept, reject, or adapt each edit.
Writing feedback you can trust
Thanis evaluates your draft and gives you reproducible, explainable recommendations, so every change is deliberate.
