Originality.ai is a content checker that scans text for AI-generated writing and plagiarism, and also grades readability, grammar and factual claims. You paste, upload or link a page and get scores. It has a limited free option, and Pro is $12.95 a month billed yearly. Treat its scores as a signal, not proof.

• Best for publishers, agencies and editors who review freelance or outsourced writing.
• Free: 10K words one time. Pro: 200K words a month. Enterprise: 1.5M words a month.
• One credit scans 100 words.
• AI detection is probabilistic, so a score alone should not decide anything important.

What Originality.ai does

Originality.ai bundles several checks into one scan. The AI checker estimates whether text was written by a model, the plagiarism checker looks for copied passages, and further checks cover grammar, readability, a content-quality score against a guideline you set, and factual claims or hallucinations. You add text by pasting, uploading a file or giving a URL, and review a score for each selected scan.

A Chrome extension works in Google Docs and records a writing replay, a playback of how a document was written, which gives a writer a way to show authorship. There is also an API, an MCP connection and a Moodle plugin for schools.

Pricing

Pricing is by words scanned. One credit covers 100 words.

Extra team seats cost extra on both paid plans. Extra credits can be bought separately.

Who Originality.ai fits

It fits people who review written work from others: content agency editors, publishers checking freelancers, SEO teams, and educators who want a second opinion. It is a worse fit for a single writer checking their own work occasionally, where the free allowance may be enough.

If you use AI to draft and want a general marketing assistant instead of a checker, look at Simplified. For turning a script into video, see Synthesia. For presentations and slides, Decktopus is covered next door.

What a score can and cannot tell you

AI detection estimates a probability. Originality.ai says its detector performed well in third-party studies and links those studies from its homepage; read them yourself, since a vendor’s own summary is not independent. In practice a high score is a reason to ask a question, not proof that someone cheated, and a low score does not guarantee a human wrote the text. Do not use a score alone for decisions that affect someone’s work, pay or grades. Also check what the tool does with the text you upload, particularly for client material.

Where it sits in a content workflow

A checker is the last step before publishing, not the first. Run a draft through the plagiarism and readability checks, apply the guideline check if you work to a style brief, and keep the writing replay for contributors whose work might be questioned. If you order drafts from tools such as Simplified or Decktopus, a scan before publishing helps you see what a reader or an editor might flag.

How Originality.ai compares

Among the content and business tools compared, Originality.ai is the quality-control tool. It sits in the AI category, and the Simplified listing covers the opposite side, generating content.
