What it is

The tool reads full text passages, identifies 26 specific artificial writing patterns across four categories (such as forced triads, staged run-ups, and inflated significance), and rewrites the prose. It shows its work by outputting an initial rewrite, a critique, and a final version.

Who it's for

It suits content writers, editors, and localization professionals who want to eliminate predictable AI phrasing from drafts. It does not suit those looking to evade AI detection tools, as detectors will still flag most of its output.

Key features

Targets 26 AI Patterns

Removes common structural tells like 'Not X but Y', forced triads, and one-line closers.

Voice Matching Support

Matches your specific writing rhythm and quirks when you supply a 2-3 paragraph sample.

Transparent Rewrite Process

Displays the first rewrite, a short critique, and the final version when processing text.

Preserves Structural Integrity

Leaves code, data, frontmatter, and link targets untouched when pointing at a file.

Our honest verdict

What's great

  • Eliminates repetitive AI phrasing like 'delve', 'testament', and 'landscape'
  • Keeps every factual claim and opinion intact from the original text
  • Integrates directly into agent workflows like Claude Code and Codex
  • Allows voice matching using your own writing samples

Where it falls short

  • Does not bypass AI detectors and detectors will still flag the output
  • Requires an underlying AI coding agent or compatible CLI environment to run
  • Editing quality depends heavily on the capabilities of the host agent
Cost

Pricing & license
