Try Hemmingway-1

Do you need an AI humanizer, or a better model?

Start with the model. A humanizer edits a draft that already exists. It can take out the signs of machine writing, but what it hands back is the same draft with less in it. A model that writes well gives you something better to edit.

Most humanizers are lists of rules. Humanizer, a Claude skill with more than 46,000 GitHub stars, is one Markdown file of patterns taken from Wikipedia's Signs of AI writing: inflated importance, groups of three, em dashes, a cheerful last line. Your agent looks for them and rewrites. When we tested it, it cut a 67-word launch announcement to 45 words and kept every fact. It also kept the pitch, because the rules remove patterns and leave the intent alone. In a second test, the same agent with a plain editing request and no skill returned nearly the same text.

The same brief, given to Hemmingway-1

We sent the brief behind that announcement through the demo above, which adds no system prompt: “Write a short launch announcement for our notes app. PDF search has shipped, and it covers the full text of every document.” The whole reply:

PDF search is here.

Every document in your library is now fully searchable. Not just titles, not just metadata, the actual text inside.

You type what you remember. You get the page.

Thirty-two words, no preamble and nothing to delete. It is not free of patterns: the bold first line and “not just…, not just…” are both on Humanizer's list. This was one run on one brief, on September 22, 2026, and the 67-word draft in our earlier test was written to be caught. Read it as a picture of where each tool does its work, not as a contest.

When a humanizer is still the right tool

• The draft is already yours. Your facts and your argument are in it, and it only needs cleanup. Humanizer's strictest rule is that a name, number or claim must come from the source. A model writing from a prompt knows only what the prompt says. That gap is smaller in StashBase, where Hemmingway is a writing skill your agent uses and drafts beside your notes and sources.
• You want it to sound like you. Humanizer can follow a few paragraphs of your own writing. Hemmingway-1 has one voice, and it is not yours.
• You write in another language. Its makers call Hemmingway-1 English-first.

Neither one is a way past an AI detector. Humanizer makes no detector claim, and in Hemmingway's own tests “sounds like a person” was judged blind by another model, not by a detector or a panel of readers. To rewrite a draft you already have, paste it into the humanizer, which runs on this model. The longer version is AI humanizer or a better model.
