## AI Scanner

AI Scanner is an online AI content detector aimed at anyone who needs to judge whether a piece of text was machine generated. The workflow is deliberately short: paste up to 3,000 words or upload a document, press the detect button, and wait a few seconds for an AI score and a sentence-by-sentence report that highlights the passages most likely produced by an LLM. Unlike many checkers, it does not require an account and does not place its core results behind a paywall.

The tool advertises cross-model detection, meaning it looks for patterns associated with content from multiple popular language models rather than tuning to a single one, and it also claims to catch AI text that has been lightly edited or run through a paraphraser. The site documents its own limits honestly: short inputs under roughly 300 words are harder to assess, and no detector can guarantee 100% accuracy, so false positives and false negatives remain possible.

Alongside the detector, the same site offers an AI text humanizer, a plagiarism scanner and a paraphrasing tool, making it a small toolkit for reviewing drafts before submission. The site states that submitted text is not stored after analysis and that data is encrypted in transit and at rest.

**Pricing & Plans:** Free. The AI detector is offered at no cost with no reasonable scan limit and no account required; companion tools are listed on the same site.

- **AI score with sentence breakdown:** Returns an overall authenticity score and highlights individual sentences flagged as likely AI-generated.
- **Cross-model detection:** Looks for writing patterns across content from popular LLMs such as ChatGPT, Claude, Gemini and Perplexity rather than a single model.
- **3,000-word scans and file upload:** Analyse up to 3,000 words per scan or upload a text document, with longer texts handled in chunks.
- **Edited and paraphrased AI detection:** Designed to catch both raw model output and AI text that was subsequently rewritten or manually tweaked.
- **No account, privacy-focused processing:** No sign-up required, data encrypted in transit and at rest, and submitted text not retained after the report.

**Strengths:** Free with no account or paywall on core results; Sentence-level highlighting makes results actionable; Covers multiple model families rather than one; File upload plus a generous word allowance

**Limitations:** Advertised accuracy claims cannot guarantee error-free results; Struggles with very short texts under a few hundred words

## Copyleaks

Copyleaks has focused on content integrity since 2015, starting with plagiarism detection and expanding into AI detection and governance as generative models spread. Its core AI Detector analyzes text across more than 30 languages and can identify output from leading models such as ChatGPT, Gemini, Claude and DeepSeek, while its Plagiarism Checker searches a database covering 60 trillion websites, 16,000+ open-access journals and millions of internal documents to catch copying, paraphrasing and character manipulation. A unified multi-modal layer adds detection for video, audio and images, aiming to replace fragmented single-purpose tools.

For organizations, Copyleaks goes beyond individual checks with a scalable API that plugs content analysis into existing workflows, LMS platforms and publishing pipelines. Its compliance and governance use cases map to academic integrity, generative AI governance, code governance, IP and copyright protection, and detection of unauthorized LLM usage. Reporting dashboards, integrations and role-based controls help teams act on results at scale.

Founded as a plagiarism tool, Copyleaks now serves both individuals and large institutions. Free web tools give students and writers quick access to the AI Detector and Plagiarism Checker, while paid enterprise plans provide higher volumes, richer reporting and dedicated support. The company reports 100+ countries, 500+ enterprise and education customers and tens of millions of monthly scans.
