Writer.com AI Content Detector

An entry in the Humanizer Wiki directory of AI-text detectors.

Strengths

Was free and required no login while it operated
Accepted either pasted text or a URL
Returned a simple, easy-to-read human-percentage score

Limitations

Discontinued on December 22, 2025 and no longer available
Short input limit and weak handling of paraphrased or hybrid text while active
Prone to false negatives, including marking AI-edited content as human

Overview

Writer.com, an enterprise AI writing platform, for several years offered a free, no-login AI content detector at its website. Users could paste text or point it at a URL, and it returned a straightforward percentage indicating how much of the content read as human-written. It was popular as a quick, frictionless check. Writer has since refocused on its enterprise agentic-AI platform and retired the consumer detector.

Accuracy in practice

While it was active, Writer’s detector reported a single human-content percentage rather than a headline accuracy figure. Reviewers found it usable on straightforward, unedited AI text but noted a short input limit and weak handling of paraphrased or hybrid content, along with a tendency toward false negatives, including marking AI-edited text as human. Like all detectors, its output was probabilistic rather than proof. As of this review the tool is no longer available: Writer discontinued the detector and its legacy detection API on December 22, 2025.

Summary

Writer.com’s AI content detector was a simple, free, no-login option, but it has been discontinued as of December 22, 2025, and its detection API was retired at the same time. This entry is retained for reference; the tool can no longer be used.
