Free writing tools
Three free tools. Two are for one complaint, that a draft reads like AI: one marks the habits and leaves the editing to you, the other rewrites the passage and shows you what changed. The third starts before there is a draft and turns your notes into an email. None needs an account, and none is a detector — nothing here will tell you who wrote a piece of text, because we do not think an honest answer to that exists.
Score it, or rewrite it
Start with Slop Score when you want to know what is wrong and edit it yourself, and go to the Humanizer when you would rather read a whole rewrite against your original. Both on one draft is a reasonable way to work: score it, rewrite it, then score the rewrite and see what the model left behind.
- Slop Score
Marks the habits that make writing read as AI — stacked transitions, “not X, but Y”, the rule of three — in place in your text, and scores them per hundred words, so a long piece is not punished for its length. Higher is worse. It matches 12 habits and nothing else, which is why it can run in your browser with nothing uploaded, and why you can check a draft you would not paste into a website.
- Sound Less Like AI
Paste a draft and Hemmingway-1 writes it again from what it means, instead of editing out patterns from a list. Your draft is on the left and the rewrite on the right, and one toggle marks what the rewrite added and strikes through what it cut, so you can see for yourself whether it kept your facts and numbers. The box takes up to 1,000 characters, about 150 words: an email or a couple of paragraphs.
Or start from notes
When there is no draft yet, only what you need to say, the email writer turns a few lines of notes into the email. It is told to add nothing the notes do not say, so there is less to fix afterwards.
- Turn Notes into an Email
Write down who the email is to and what you need to say, in any order, and Hemmingway-1 writes it: your dates and numbers kept, no filler, no bracketed placeholders. It writes in the language of your notes or in any of 32 you pick, and it can answer an email too, if you paste it above your notes. The box takes up to 1,000 characters, about 150 words of notes.
The model behind all three
All three tools run on Hemmingway-1, a 27B open-weight model fine-tuned to write text that reads as if a person wrote it. The Humanizer and the email writer are that model from end to end. Slop Score only calls it when you press the button, and answers with an editor's note on the passage rather than a rewrite. If you would rather give it your own instructions, chat with Hemmingway-1 is the plain chat page.
Whether to fix a draft with a humanizer or start with a better model is the longer argument in AI humanizer or a better model, and How to Write with AI Without Losing Your Voice is the method underneath all three pages.
Past one passage
A pasted passage is all any of these pages can see. StashBase is an open-source, local-first writing workspace where you draft and revise with Claude Code or Codex beside your own files, so an edit can be checked against the notes it is supposed to agree with. Humanize works in the document there: select prose in a Markdown file and the rewrite comes back as suggested changes to accept or reject.
