What is Scribbr?
Scribbr is an AI checker that helps students write and submit academic papers that meet institutional standards. It scans submitted text at the paragraph level to detect AI-generated and AI-refined content, flags grammar errors, and proofreads full papers for clarity and writing quality. Students can generate citations in multiple academic styles and run them through a citation checker to catch formatting errors before submission. A built-in summarizer pulls key points from source material to support the research and drafting process. The paraphrasing tool rewrites passages in different words while preserving the original meaning. The AI humanizer rewrites AI-generated text to read as human-written before submission.
Features & Benefits
- AI Detector: scan submitted text and return a percentage score indicating the likelihood of AI-generated or AI-refined content using proprietary detection algorithms trained on output from tools like ChatGPT, Gemini, and Copilot. It classifies each passage as fully human-written, human-written and AI-refined, AI-generated and AI-refined, or fully AI-generated. The AI detector can analyze text written in English, Spanish, German, and French.
- Plagiarism Checker: compare submitted text against a database of web pages, news articles, and academic journals to identify copied passages.
- Citation Generator: generate formatted citations in APA, MLA, Chicago, AMA, IEEE, and ACS citation styles.
- Citation Checker: review existing citations using AI or human editors to identify formatting errors.
- Grammar Checker: check short text fragments for grammar errors.
- AI Proofreader: review a full paper for grammar, clarity, and writing quality using AI.
- Paraphrasing Tool: rewrite text passages in different words while preserving meaning.
- Summarizer: extract key points from longer texts to reduce reading time.
- AI Humanizer: rewrite AI-generated text to read as human-written.

Real-World Applications
A student finishing a thesis may want to confirm their paper meets institutional guidelines before submitting. The AI checker scans the full document and returns a paragraph-level breakdown showing which sections are fully human-written, AI-refined, or AI-generated. The plagiarism checker adds a second pass against web pages, journals, and news articles to catch any copied passages. Citations can be generated in APA, MLA, or Chicago and verified for formatting errors in the same session.
Instructors reviewing student submissions can run each paper through the AI detector to get a passage-level classification rather than a single document-wide score. That breakdown shows not just whether AI was involved, but how it was used at each point in the writing. The grammar checker supports a closer read of any flagged sections.
Graduate students who need to rephrase source material in their own words can use the paraphrasing tool to rewrite passages while preserving the original meaning.
A student working from multiple sources can use the summarizer to pull key points before drafting begins. The AI proofreader reviews the finished paper for grammar, clarity, and writing quality. The citation checker then verifies that all references are formatted correctly before the paper goes in.
