Originality AI
Originality.ai is a content verification platform for checking whether text may have been generated by AI, copied from another source, or published with factual and editorial problems. It is primarily used by publishers, agencies, educators and teams that review large volumes of written content.
The AI detector produces an overall probability score and highlights sentences most likely to contain AI generated writing. Multiple scanning modes are available, including Deep Scan for closer analysis and AI Allowance for teams that permit some AI involvement. The multilingual model supports 30 languages.
AI detection remains probabilistic. Human writing can be incorrectly flagged, while edited or mixed human and AI text may escape detection. Originality.ai states that its score should not be used by itself when making academic misconduct decisions. Writing history, source material and human review remain important.
The plagiarism checker identifies direct matches, paraphrased passages, patchwork plagiarism and text assembled from several sources. Results include source links and sentence highlights. Documents can be pasted into the editor, uploaded as files or scanned from a URL.
Originality.ai has expanded into a broader editorial quality control toolkit. You can run grammar, readability, content quality and fact checking scans alongside AI and plagiarism checks. Its Guideline Checker reviews writing against preset or custom requirements, which can help agencies and editorial teams maintain client or publication standards.
The Chrome extension works inside Google Docs and records the writing process through Writing Replay. This gives writers and students a way to show how a document developed rather than relying entirely on a detector score. Shareable links and PDF reports make completed checks easier to send to editors, clients or instructors.
Team accounts include user roles, activity tracking, shared reports and higher usage allowances. Publishers and software companies can connect the detector to existing workflows through the API or process content in batches.
A limited free plan covers AI detection. Paid subscriptions and pay as you go credits provide access to the wider checking suite. Credit consumption varies according to the scans selected.
