AI humanizer with a scoreboard

Make AI writing sound human.

Paste a draft that ChatGPT or Gemini wrote for you. Emberquill rebuilds it with natural rhythm and everyday vocabulary, then scores the result so you can see the difference instead of taking our word for it.

10 free rewrites a day. No card required.

Paste your draft

Drop in any AI-generated paragraph, article, or email. Up to 1,000 words on the free plan, 5,000 on paid plans.

2

Pick a level and engine

Four levels, from a light polish to Ghost, which rebuilds every sentence. Run it on the fast engine or the deeper one.

3

Check the score

Every rewrite comes with a before-and-after AI score, a sentence heat map, and alternatives for any sentence you don't like.

Four levels

How far do you want to go?

Every level rewrites and scores your text. The higher you climb, the more the structure changes.

Level 1

Polish

Fixes the obvious tells: stiff transitions, dead filler, machine-flat phrasing. Your structure stays exactly as it is.

For drafts that are almost there.
Level 2

Natural

Rewrites sentence by sentence with varied length and rhythm, and swaps textbook vocabulary for words people actually use.

The everyday workhorse.
Level 3

Bold

Restructures whole paragraphs, merges choppy sentences, and opens with hooks instead of formulas. Adds a translation hop for extra variation.

When Natural isn't enough.
Level 4

Ghost

Our strongest setting. Translates your text through intermediate languages to break its fingerprint, then rebuilds it from scratch.

For text that keeps getting flagged.
Built-in detection score

See the graph, not just the promise

Every rewrite ships with a before-and-after AI likelihood score. A sentence heat map shows exactly which lines still read like a machine, so you can fix them instead of guessing.

  • Before and after metersWatch the score drop across the whole text, not just a sample.
  • Sentence heat mapPer-sentence scoring flags the spots that still sound robotic.
  • Score trend over timeYour last 30 scans plotted on a sparkline so you can track your progress.

Two engines, your choice

Fast when you're in a hurry, thorough when it matters

Quill runs on DeepSeek Chat and returns a clean rewrite in seconds. Reasoner runs on DeepSeek Reasoner, thinks longer, and pushes harder on structure and flow.

Every rewrite is validated before it reaches you: banned AI phrases purged, sentence overlap capped, rhythm checked. If a result fails, the engine retries instead of handing you slop.

  • Sentence alternativesClick any rewritten sentence to swap in a different phrasing.
  • No auto-renewalsPaid plans run 30 days and stop. We never charge you silently.
Honest answers

Questions people actually ask

Will my text pass every AI detector? +
No tool can honestly promise that. Every rewrite comes with a before-and-after score from our built-in statistical model, which measures the patterns detectors look at: sentence rhythm, repeated openers, flat vocabulary. If you add an Originality, GPTZero, or Sapling API key in your configuration, the same report switches to verified results from that provider. Treat any score as a strong guide, not a guarantee, and always read the final text yourself.
What makes Ghost different from the other levels? +
Ghost is built for text that keeps getting flagged. It first translates your draft through intermediate languages, which breaks the sentence fingerprint that detectors match against, then rebuilds the whole passage from scratch with our strongest prompts. It takes longer and changes more of your wording, which is the point.
Which rewrite engine should I pick? +
Start with Quill. It is fast, cheap on credits, and handles most everyday drafts well. Move to Reasoner for important pieces: long articles, academic tone, or text where the first pass still sounds stiff. Reasoner thinks longer and produces more varied structure.
How does pricing work? +
Paid plans last 30 days and include a grant of word credits: 100,000 on Starter, 400,000 on Pro. There is no subscription and no auto-renewal. When your 30 days end, you simply drop back to the free plan unless you choose to buy another month.
What do you do with my text? +
Your draft is sent to the rewrite engine you selected so it can do the work, and the result is stored in your account history so you can revisit it. We keep the minimum needed to run the service, as described on our privacy page.
Is there really a free tier? +
Yes. Free accounts get 10 rewrites a day with 1,000 words per input, sentence alternatives, and the detection score. It is a real tier, not a 3-day trial.
