Moxby AI Content Detector (formerly ContentDetector.AI)
Moxby AI Content Detector is an AI detection plugin for the Moxby desktop agent that scans Doc editor drafts for robotic writing patterns. It flags repetitive phrasing, predictable sentence flow, and thin sections at the sentence level, then pairs those signals with an AI Humanizer skill that guides rewrites inside the same workspace. You install it from the Moxby marketplace after downloading Moxby for Mac or Windows.
Where standalone paste-and-check detectors chase authorship verdicts, this tool takes the opposite stance: it does not claim to prove whether text was written by AI or a person. It treats detection output as editorial guidance for writers who want to polish AI-assisted drafts before publishing, which is a narrower and more honest job than classroom misconduct screening.
Content marketers, SEO teams, editors, and creators can run an AI Scan from the Doc editor, review flagged sentences, and use the Humanizer skill to add examples, vary structure, and tighten voice. Analysis runs locally through the Moxby gateway, so scanned text is not stored on vendor servers. The marketplace listing is free, though using Moxby itself may eventually require a paid seat if you outgrow the free message allowance.
AI Scan button inside Moxby's Doc editor flags individual sentences for robotic phrasing
Uses perplexity scoring, burstiness patterns, and model-specific fingerprints during analysis
AI Humanizer skill bundled with the plugin guides natural rewrites in the same editor session
Marketplace listing is free at version 1.4.6 with no per-scan usage fees
Detection processing runs locally through the Moxby gateway with no server-side text storage
Works on text from ChatGPT, Claude, Gemini, or handwritten drafts since it targets writing patterns
Local analysis keeps scanned text off vendor servers during detection runs.
Sentence-level flags point to specific rewrites instead of a single whole-document score.
Bundled AI Humanizer skill guides rewrites without leaving the Moxby Doc editor.
Marketplace listing is free with no per-scan usage fees on the detector itself.
Clear disclaimers that results are editorial signals, not authorship proof.
Requires downloading Moxby for Mac or Windows; there is no browser-only paste-and-check page.
Free Moxby tier limits AI chat messages, and Pro costs $25 per seat monthly when you need more.
Does not verify authorship, so it is a poor fit for academic misconduct or legal decisions.
Detection works best on drafts above 100 words, so very short snippets give weaker signals.
Is Moxby AI Content Detector free to use?
Yes. Moxby AI Content Detector is listed as free in the Moxby marketplace with no per-scan charges. You still need the Moxby desktop app, which offers a free tier with limited AI messages and optional Pro plans at $25 per seat monthly.
How does Moxby AI Content Detector scan my writing?
Moxby AI Content Detector adds an AI Scan action to the Doc editor inside Moxby. It analyzes your draft for robotic patterns using perplexity scoring, burstiness signals, and model-specific fingerprints, then highlights sentences worth revising. Longer samples above 100 words produce more useful feedback.
Does Moxby AI Content Detector store scanned text?
No. Moxby AI Content Detector runs analysis through the Moxby gateway on your machine, and the vendor states your text is not stored or logged. All detection processing stays inside your local Moxby Agent session.
What AI models can Moxby AI Content Detector review?
Moxby AI Content Detector does not check which model wrote a draft. You can scan text from ChatGPT, Claude, Gemini, or your own handwriting because it looks for robotic writing patterns rather than model-specific watermarks.
Can Moxby AI Content Detector prove AI authorship?
No. Moxby AI Content Detector explicitly does not verify authorship or guarantee accuracy. It is meant as an editorial review aid for improving draft quality, not as proof for academic, employment, or legal decisions.
What platforms does Moxby AI Content Detector support?
Moxby AI Content Detector requires the Moxby desktop app on Mac or Windows. There is no browser-only checker at contentdetector.ai anymore; the domain redirects to the Moxby marketplace listing.
