AI Detector Pro

AI Detector Pro combines AI-writing detection with tools for revising and humanizing text in a web app. It suits students and employees who need both a scan and an editing workflow, especially across several languages. The free tier is useful for occasional checks, but the product’s own accuracy warning and tight allowance make it a poor basis for consequential authorship judgments.

Overview

For English documents, the service highlights passages likely to trigger AI detectors, shows predicted text, and identifies overused AI phrases. Detection also covers Spanish, French, Arabic, German, Korean, and Portuguese writing, giving multilingual users broader reach than an English-only checker. The company says randomness in AI models means no tool is completely accurate, and that false identifications and incorrect humanizations can occur. Treat results as review signals rather than proof of who wrote a document.

Privacy is a significant consideration. The company says it does not sell personal information, but user text may be sent to third-party AI models for core functions. Entered content is automatically deleted at the start of the fourth month after submission; documents created in the product remain until you delete them or delete your account. Stated safeguards include encryption, secure network configuration, transfer restrictions, and limited employee access.

Key features

AI Eraser proposes alternative English wording and lets you control how extensively a passage changes. That is helpful when you want to revise a draft without surrendering control of its voice, although changing wording cannot guarantee that a detector will accept the result. Tone analysis, phraseology checks, and a pinpoint editor add focused ways to inspect and refine writing around the main scan.

Basic and Unlimited subscriptions include plugins for Microsoft Word and Google Docs, so subscribers can work in familiar editors instead of moving text manually. API access requires an eligible subscription. Report requests cost $0.09 per unit of up to 4,000 characters; other endpoints are free. Enterprise customers can request API and white-label arrangements, with discounts or pricing determined by requirements and query volume.

Pricing

The Free plan costs nothing and includes three AI scans per month. It includes no humanizations, and API usage costs extra. This is adequate for infrequent personal checks, not regular coursework, editorial throughput, or automated processing.

Basic has custom pricing and raises the allowance to 103 AI scans per month. It adds unlimited humanizations, the pinpoint editor, tone analysis, multilingual detection, and Word and Google Docs plugins. Choose it when those editing and integration features matter and your monthly scanning fits a fixed quota; the quota is the main trade-off against Unlimited.

Unlimited also has custom pricing and removes the scan ceiling while retaining unlimited humanizations, the editors and analysis tools, multilingual detection, and both plugins. It is the logical fit for frequent reviewers or teams, but the page does not publish a price, so you need a quote before comparing total cost.

Platforms

AI Detector Pro runs on the web. Word and Google Docs plugins are part of Basic and Unlimited, while API access is available to eligible subscribers and enterprise customers.

Who it's for

The product is aimed at students and employees concerned about unfair cheating accusations, and at writers who want detection alongside controlled rewriting. Multilingual users benefit from its seven-language coverage, while organizations can investigate API or white-label deployment. It is not a good choice when you need a definitive authorship verdict, guaranteed detection accuracy, or a policy that keeps submitted text away from third-party AI models.

Pros and cons

• Pro: Detection and revision tools sit in one workflow, including adjustable English humanization, tone analysis, phraseology, and pinpoint editing.
• Pro: Seven-language detection and Word and Google Docs plugins broaden practical use beyond a basic web checker.
• Pro: Unlimited scans and humanizations are available on the top plan, with API and white-label paths for larger deployments.
• Con: The free plan allows only three AI scans monthly and no humanizations, limiting repeat use.
• Con: The company acknowledges false identifications and humanizations, so results should not decide disciplinary or reputational outcomes alone.
• Con: User text may be shared with third-party AI models, and documents created in the service persist until account or user deletion.

Alternatives

For a broader directory of options, see AI Detection Software, AI Content Detectors, and AI Content Detection Software.

Pick Trinka instead if you need a freemium writing service spanning API, extensions, desktop, self-hosted, and web platforms, with no free trial. Grammarly is the alternative for a freemium product whose listed Free plan provides 100 AI prompts per month and whose Pro plan costs $12 a month.

Sapling suits users wanting a free trial, API and extension access, and a Free plan capped at 2,000 detector characters per check, five files per batch, and 20 snippets. Choose SlopProx for a free, open-source desktop and browser-extension option. ZeroTrue offers 100 free detections per month with API access, a web dashboard, and community support.

AI Detect is a free local-use option with no API key and no usage limits. Detecto provides starter credits on its free tier and a 6.99 USD monthly Student plan. GPTZero is worth considering for a free allowance of 10,000 words or 50,000 characters per month and API, extension, and web access.

Verdict

Choose AI Detector Pro if you want multilingual detection, adjustable English rewriting, and document-editor plugins in one service, and can work within the free quota or obtain a custom subscription. Look elsewhere if you need a larger published free allowance, local-only handling, or confidence that a detection result is definitive; its explicit accuracy caveat and third-party model sharing are central limitations.
