Unicode Cleaner
Clean selected invisible characters, compare before and after, and copy the result. Joiners are preserved unless you choose to remove them.
Free tools
Explore the tools. No account needed.
Rewrite or humanize a draft, inspect or clean Unicode, tidy em dashes and Markdown, compare texts and count words. Every tool takes your own text and works without an account; each page says whether it runs in your browser or on the server.
Clean up
Markdown Cleaner
Normalize Markdown or convert it to plain text. Preview the cleaned result and copy exactly what you see, without sending your draft anywhere.
Clean up
Em Dash Cleaner
Keep one em dash per sentence and turn the extras into commas, semicolons or colons. Closed-up ranges stay intact; spaced hyphens are opt-in. Runs in your browser.
What these tools do not do
They do not promise detector evasion, and they do not rewrite an argument. What they read and change is register and characters, measured against our published taxonomy, nothing more.Which models watermark the text they generate is a separate question, with a different answer for each provider. See the watermark database.
What the engine is, what it keeps and for how long are questions about the product rather than about one tool. Read the general FAQ.
Frequently asked questions
Which tools can I use on my own text?
Every tool on this page accepts your own text; none of them shows a fixed sample in place of your input. Each tool page says, before you paste anything, whether the work happens in your browser or on the server, and a sample is only ever loaded when you ask for it.
Which tools process text in my browser?
Tools labelled “Local processing” at the top of their page inspect, clean, compare or count text in your browser, without uploading or storing your input. Tools built on the shared GenPolish AI service send a submitted draft to the server and use the same rewriting service and workspace as Rewrite; their page says so above the editor, and nothing is sent until you submit.
Do I need an account or JavaScript?
The browser-only tools need JavaScript, but no account. The AI editor offers a limited anonymous trial; signed-in runs use your available word balance, and its form also supports submission without JavaScript through Rewrite. Following a link between tools, or to the editor, never transfers your text.
