AI Content Detector by SEOToolsII

AI Content Detector by SEOToolsII is a web-based tool designed to analyze text and determine the likelihood that it was generated by artificial intelligence, such as models like ChatGPT, GPT-4, Claude, or Gemini. It serves content creators, educators, SEO professionals, publishers, and businesses who need to verify the originality and human authorship of written material. The tool addresses growing concerns about AI-generated content in academic integrity, search engine optimization (where unique, human-written content is often favored), and editorial transparency. Users paste or upload text, and the detector provides a percentage score indicating AI probability, often with highlighted sections. It is positioned as an accessible, no-frills utility within a broader suite of SEO and webmaster tools, focusing on quick, straightforward analysis without requiring deep technical knowledge or account creation for basic use.

Use Cases

1

Academic Integrity Enforcement

Educators and university administrators use the detector to screen student submissions like essays, reports, and homework. By pasting suspicious text, they can get an initial probability score to identify potential AI-assisted plagiarism. This helps uphold academic standards and initiates conversations about proper tool use, though it is typically used as part of a broader evidence-gathering process, not as sole proof.

2

SEO Content Quality Assurance

SEO specialists and content marketers analyze blog posts, product descriptions, and website copy to ensure a high degree of human originality, which is believed to be favored by search engine algorithms. Identifying heavily AI-generated sections allows for strategic rewriting to improve content quality, user engagement, and organic search rankings, protecting site authority.

3

Publishing and Editorial Review

Editors at news outlets, magazines, and content agencies vet submissions from freelance writers or staff to maintain a authentic, human voice and avoid publishing generic AI-generated material. The detector provides a quick check to flag pieces that may require deeper editorial scrutiny or revision before publication, safeguarding brand reputation.

4

HR and Recruitment Screening

Human resources professionals and hiring managers use the tool to assess cover letters, writing samples, and take-home assignments submitted by job candidates. A high AI probability score might indicate a candidate did not personally complete the work, helping to filter out dishonest applicants and ensure skills assessments are genuine.

5

Content Marketplace Moderation

Platforms that host freelance content creation services (e.g., article marketplaces, ghostwriting services) can integrate the API to automatically screen seller submissions. This helps enforce policies against selling fully AI-generated content as human-written, maintaining marketplace quality and trust between buyers and sellers.

How to Use

  1. Step 1: Navigate to the primary URL https://seotoolsii.com/ai-content-detector using a web browser. No account sign-up is required for basic usage.
  2. Step 2: Locate the large text input box on the main page. You may also find an option to upload a text file (.txt) directly.
  3. Step 3: Paste the text you wish to analyze into the input box. The interface may have a character or word limit for the free version.
  4. Step 4: Click the prominent 'Check' or 'Detect AI Content' button to submit the text for analysis.
  5. Step 5: Review the results page. It typically displays an overall 'AI Content Probability' percentage score and may highlight specific sentences or paragraphs flagged as likely AI-generated.
  6. Step 6: Interpret the results. A high percentage (e.g., above 80%) suggests strong AI signals, while a low percentage suggests human-like writing. The tool may provide brief explanations.
  7. Step 7: For repeated or batch analysis, consider using the tool's API if available (for paid plans) to integrate detection into your own workflows or applications.
  8. Step 8: Use the results to inform your next actions, such as revising content, conducting further manual review, or documenting originality for academic or publishing purposes.
