Originality AI

Originality.ai checks whether text was written by a person or by AI. It scans pasted text, uploaded files, or a page URL, then scores each part as AI, human, or mixed. Publishers, agencies, schools, and freelance writers use it to verify work before it goes live. The same scan can also check plagiarism, verify facts, and rate readability. Results highlight the exact sentences that look machine-written, so editors can review them instead of guessing. A free scan on the homepage lets anyone test the detector before buying credits.

Key Features

1. AI Detection

Its 5.0 detector labels text as AI, human, or mixed, and third-party studies rank it as the most accurate detector available.

2. Plagiarism Checking

The plagiarism scan compares submitted text against web sources and flags matching passages for editors to review.

3. Fact Checking

A fact-check scan reads the sources cited in a document and flags claims that do not match the source material.

4. Readability and Content Quality

Content quality scans score readability and clarity, helping editors spot weak passages before anything is published.

5. Sentence Highlights and Reports

Sentence highlights show which lines look most likely AI-written, and results can be shared as a link or PDF report.

6. Chrome and Google Docs Extensions

Browser and Google Docs extensions let writers and editors check text inside the tools they already use daily.

7. API and Team Controls

An API connects detection to publishing platforms, while team roles and controls suit agencies, schools, and enterprises.

Frequently Asked Questions (FAQ)

What does Deep Scan add to a normal scan?

Deep Scan explains why flagged passages look AI-written and suggests ethical edits that make the wording sound more natural.

How can writers prove they wrote a piece themselves?

The Chrome extension records a writing replay that shows the text being typed, giving writers proof of authorship.

Can schools check student work with it?

Yes. Schools and universities use it for student assignments, and it integrates with learning platforms such as Moodle.

What happens to text after a scan?

Submitted text is encrypted, scan history can be deleted in one click, and users can opt out of AI training use.

Can it catch text paraphrased to hide AI use?

Yes. The detector is trained on adversarial data, so text edited with paraphrasing tools can still be flagged as AI.
