How to humanize text
- Paste or open the text.
- Choose a natural, casual or professional voice.
- Select Humanize, then read it through and copy the result.
What it changes
It varies sentence length, swaps buzzwords and filler such as “leverage”, “moreover” and “in conclusion” for plain words, and removes stiff transitions, while keeping your meaning and facts.
Use it honestly
Use it to make your own drafts and notes easier to read. It is not designed to hide where a text came from, and you should follow the rules of your school or workplace about AI.
Questions about AI humanizer
Is it really free, with no limits?
Yes. The AI model runs on your own device, so it costs us nothing per use: there is no sign-up, no subscription, no daily limit and no word cap.
Is my text uploaded?
No. The AI model runs in your browser tab on your own device, using WebGPU. Only the model itself is downloaded, once, from Hugging Face; the text you work on never leaves the tab.
Will it keep my meaning?
Yes. It is told to keep the meaning, facts, language and formatting. Read the result before you use it, as small models sometimes change a detail.
How big is the download, and which model should I choose?
Between about 0.9 and 3.4 GB, once; your browser keeps it for next time, and every AI tool uses the same model. Gemma 2 2B is a good balance. Llama 3.2 1B is the quickest on older devices, and Qwen 3 4B gives the best results on a computer with a recent graphics chip.
Which browsers work?
Browsers with WebGPU: current Chrome and Edge on Windows, macOS and ChromeOS, Safari 26 or later, and Chrome on recent Android phones. It runs faster on computers with more graphics memory.
