AI Copywriter

A clean, document-style writing surface with everything a copy brief needs: templates that produce predictable structure, inline suggestions you accept or ignore, a brand voice you control, and a live human score that measures readability, rhythm and the clichés that give AI text away — with a one-click humanize to fix it. Every score is computed deterministically, not by a model guessing.

  • Social captions, ads and campaign variants
  • Product descriptions, press releases and SEO metadata

KEY CAPABILITIES

04 ENTRIES
01

A human score you can trust, because it is not a model

Readability, sentence rhythm, lexical diversity and a fixed list of AI clichés are measured by deterministic code on every keystroke. The model can explain the score but cannot change it — and the UI says plainly that it is a style estimate, not a detector.

02

Humanize in one click

One button rewrites the draft to vary rhythm, prefer the active voice and drop the model tells, while preserving the meaning and your brand voice. The score updates live so you can watch the change land.

03

Inline suggestions, not replacement

Ghost text appears where the cursor is. Press Tab to accept, Escape to dismiss, or keep typing to ignore it. You stay in control of every word.

04

A document surface, not a code editor

Write on a light, serif page with a proper ribbon, tone presets and a focus mode. Version history snapshots every generation and rewrite, and export is one click to Markdown, text or Word.

EXAMPLE OUTPUTS

BRIEF → RESULT
BRIEF

“A landing page for a carbon-accounting API aimed at fintech engineers.”

RESULT

Technical headline, credibility-focused body, developer-friendly CTA — and a human score showing the draft free of model clichés.

BRIEF

“Five email subject lines for a design-system course launch.”

RESULT

Five distinct angles — outcome, curiosity, urgency, social proof, objection — each under 50 characters.

NOTEThese describe what the generator produces for a brief of that shape. Output varies by run — the specification is planned each time, not retrieved from a template.
