SmallSEOTools

SmallSEOTools is an AI checker tool. A free, no signup AI text detector from SmallSEOTools that accepts up to 2,000 words per scan and returns an AI versus human percentage split. It handles multiple languages and sits beside the site's plagiarism and grammar tools, though it reports only headline percentages rather than detailed sentence level evidence.

SmallSEOTools AI Content Detector is a browser based checker that estimates how much of a piece of text was produced by a generative model rather than a person. Text goes into a box or is uploaded as a file, the checker runs, and the output splits the sample into an AI written share and a human written share, both shown as percentages. The free ceiling is 2,000 words per check, which covers a typical blog post, essay or press release without trimming. The tool is built for people who have to make a judgement call about authorship. Teachers and admissions staff use it on assignments. Editors and fact checkers run submitted drafts through it before publication. Recruiters screen cover letters and resumes, and moderation teams triage user posts. Researchers use it to confirm that source material is not machine generated before citing it. No account is required, and the site states there is no charge and no cap on how many checks can be run. Mechanically, the site describes a multi stage process: it collects the input, extracts features such as sentence structure and overall layout, classifies the text across languages, then reports a percentage breakdown. The vendor claims 99.9% accuracy and support for languages beyond English, including French, German, Portuguese, Spanish and Italian. Uploaded or pasted content is said to be cleared from the database once the scan finishes. In practice the checker is a single purpose utility inside a much larger free toolbox, so it sits alongside the site's plagiarism checker, grammar checker, paraphrasing tool and AI humanizer. That makes it convenient for a quick verification pass without a subscription, but it is a lighter instrument than dedicated detection platforms that offer document history, team dashboards, API access, or detailed sentence level reporting. Anyone needing auditable records for institutional decisions should treat the percentage as a signal to investigate, not a verdict. The interface is available in a long list of localized versions, and feedback is collected through a contact form.
