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 [Profile (Markdown)](https://openaitools.app/tool/ai-scanner.md) ## Scribbr Scribbr was built around a simple promise: help students submit work they feel confident about. The core of the service is human proofreading and editing, delivered by a hand-picked pool of academic editors who go through an in-house training programme before they are allowed to take orders. Documents are returned with tracked changes, in-text comments and a short personal letter explaining the reasoning behind the main edits. Alongside the human service, Scribbr offers a growing library of AI writing tools. The Academic Check bundles together grammar and language review, citation checking, plagiarism scanning and AI-content detection into a single upload, which is convenient when you want one pass over an entire paper rather than juggling separate tools. Individual utilities such as the citation generator for APA, MLA, Chicago, AMA, IEEE and ACS, the paraphrasing tool and the text summarizer can be used on their own without paying for an edit. The platform also maintains a large free knowledge base of academic writing guides that has become one of the more popular ways students discover the brand. Pricing depends heavily on document length, chosen turnaround time and add-on checks, so the practical way to get a number is to upload a file and select services in the order flow. **Pricing & Plans:** Freemium model. Free tools include the citation generator, grammar checker and summarizer. Human proofreading and editing, the plagiarism checker, AI detector, AI proofreader and Academic Check are paid per document, with the final price depending on page count, delivery speed and any add-on checks such as structure or clarity review. - **Human proofreading and editing:** A vetted academic editor reviews your paper within hours and returns tracked changes, comments and an explanation letter. - **Plagiarism checker:** Scans your document against a large web and publication database to surface potentially unoriginal passages before submission. - **AI detector and AI humanizer:** Flags text likely generated by large language models and offers a rewriting mode aimed at making AI-assisted drafts sound more natural. - **Citation generator:** Creates and verifies references in APA, MLA, Chicago, AMA, IEEE and ACS styles from a URL, DOI or title search. - **Academic Check bundle:** Runs grammar, citations, clarity, plagiarism and AI-detection checks in a single upload of the whole document. **Strengths:** Combines human editors with AI tools rather than relying on one alone; Strong editorial vetting process and a large pool of academic specialists; Free citation generator and knowledge base are genuinely useful on their own; Transparent turnaround options starting from a few hours **Limitations:** Paid services are priced per document, which adds up for long theses; AI detector verdicts can still be disputed by institutions; Some premium checks require you to buy them alongside an editing order [Profile (Markdown)](https://openaitools.app/tool/scribbr.md) ## Frequently Asked Questions ### How do AI Scanner and Scribbr compare in monthly traffic?
