How it works
- Paste your text. Drop in the text you want to read more naturally.
- Pick a tone. Optionally choose natural, casual, formal or plain in Advanced options.
- Humanize. The rewritten text appears (queuing if busy) for you to copy.
About this tool
Paste text that reads stiff or robotic and get back a version that sounds like a person wrote it — same meaning, smoother flow. It varies sentence length, drops the tell-tale filler phrasing and keeps your facts and language intact. Choose a tone (natural, casual, formal or plain) to match where the text is going. It runs a language model on a GPU, so at busy times your request waits briefly in a queue and then runs. Nothing you paste is stored. Use it to polish your own drafts — not to misrepresent authorship where that matters.
What people use it for
- Smooth out a stiff or robotic draft
- Make translated or generated text read naturally
- Tighten wording while keeping the meaning
- Adjust the tone of a passage (casual/formal/plain)
