# AI humanizer: run it free, or from your agent

Rewrites up to 1,500 characters of AI-written text in plain words, with the tells removed. Check facts before using.

## Prompt

Use looot to rewrite my draft so it reads like a person wrote it: [paste the draft]. 1. Set up https://looot.ai/skill.md. 2. Search the catalog for a chat completion endpoint and check its price per token. 3. Run it with a system prompt that says: keep every fact, number, name and date, add no claims, plain words, varied sentence length, no em dashes, same language. Cap max_tokens near the draft length. 4. Return the rewrite and list any fact that changed.

## What it needs

Up to 1,500 characters of your own draft and an optional tone

## What comes back

- rewritten text
- characters before and after
- tells removed by kind
- a note when the rewrite hit the length cap

## Endpoints and providers

- openrouter: openrouter-chat

## What it costs

The tool on the web page runs live at no cost to you and is limited per hour. The results come from public data through looot. For heavier or repeated use, run the same job from your own looot account: looot bills per call and charges nothing while your agent is idle. The live price comes from the catalog and shows on the web page.

## Edit your own drafts

Turn a stiff first draft from a model into text that sounds like you, then edit it further.

## Strip the tells

Remove em dashes, hype words and stock phrases in one pass, then check the result with the AI text checker.

## Fix a post fast

Rewrite a LinkedIn post, a product update or an email in seconds before you send it.

## Agent pipelines

Give your agent the same rewrite step through looot, with the token cap you choose.

## What does the AI humanizer do?

It sends your draft to an open Gemma 4 31B instruct model with a fixed editing prompt: keep every fact, number, name and date, add nothing, use plain words, vary sentence length, no em dashes, same language. You get the rewrite and a count of the tells it removed.

## Will it keep my facts?

It is told to, and in our test run it kept the numbers and dates. Models still make mistakes and sometimes shorten a point, so check facts before using the rewrite.

## Does it bypass AI detectors?

We make no such claim. Detectors disagree with each other and flag human text too. Use this to edit your own drafts into clearer writing, and follow the rules of your school or workplace.

## How long can the text be?

1,500 characters per run on this page, and the answer is capped at 400 tokens. Line breaks are joined into one line. For longer text, your agent can run the same endpoint through looot in parts.

## Which model runs it?

Google's Gemma 4 31B instruct, through the OpenRouter chat endpoint on looot, with a fixed system prompt. It is not a fine-tuned humanizer model.

## Can I run a humanizer model locally?

Yes. Humanizer by jialinyyzz on Hugging Face is an open fine-tune of Gemma 4 12B under the Apache 2.0 license, with GGUF files for llama.cpp. looot does not run it. Use the LLM VRAM calculator to see if your GPU can hold it.

## Which languages work?

The prompt tells the model to answer in the language of the draft. English works best. Check other languages with a native speaker before you publish.

## Is it free?

Yes on this page, limited per hour. Each run is one real call on looot's own key, billed per output token. The price for your own account is shown above.

## How do I run this from an agent with looot?

Copy the prompt above into your agent. It sets up looot from skill.md, finds the chat completion endpoint, and runs it with the same rules and a token cap you choose.

## Is my text stored?

The text goes to the model provider for this one call. Do not paste personal or confidential data.
