Undetectable AI

What is Undetectable AI?

Undetectable AI is a writing utility that combines AI detection, text humanization, and content improvement. Users can paste text or upload files, check whether the system classifies them as AI-generated, and optionally rewrite the output.

The platform also advertises an AI image detector, business workflows, browser extension, and API. It is aimed at writers, marketers, and teams that want a review pass before publishing AI-assisted drafts.

The free trial is limited to 250 words; paid plans add monthly word quotas and API access. The service does not guarantee that every reader or detector will agree with its classification.

Key Features

AI detector

Paste text or upload a file to receive an AI-detection assessment. The result is a signal for editorial review, not definitive proof of authorship.

AI humanizer

Rewrite AI-assisted drafts to improve natural phrasing while retaining the intended meaning. Users should still fact-check and edit the result.

API and extension

Use API workflows and a Chrome extension to integrate checks into publishing processes.

Business plans

Custom plans offer bulk credits, non-expiring words, redistribution options, white labeling, and priority support.

How to Use Undetectable AI

1. Open Undetectable AI and start the limited free trial.
2. Paste text or upload a file; optionally select detector or humanizer mode.
3. Review the result and compare it with your original draft.
4. Edit claims, citations, tone, and structure manually before publishing.
5. Use API or business workflows only after testing accuracy for your content type.

Use Cases & Who It's For

• Editors: Add one detection and readability pass before publication.
• Marketing teams: Review AI-assisted campaign copy.
• Content operations: Use API checks in a publishing pipeline.
• Writers: Improve awkward AI-assisted phrasing while preserving meaning.
