Overview
What Originality AI is
Originality AI is designed for organizations that need a repeatable review process before publishing or accepting written work. Users can paste text, upload documents, enter a URL, scan a full site, or work through its Chrome extension, then check for AI-generated language, plagiarism, factual claims, readability, and grammar.
The detector offers models for different policies: Lite permits some light AI editing, Turbo is intended for stricter AI rules, Academic is tuned for academic and STEM-related writing, and a multilingual model supports 30 languages. The Google Docs extension adds writing replay and an auto-typing score, which can provide process evidence beyond a single classifier result.
No AI detector can prove authorship. Originality AI explicitly says scores reflect probability rather than guilt and advises against academic discipline based only on a detection score. The responsible workflow is to scan substantial samples, compare multiple works, review matched sources and writing history, ask the author for context, and use the result as one signal among several.
Use cases
Who Originality AI is best for
The strongest fit depends on the job you need the product to complete, not the size of its feature list.
Editorial operations
Run repeatable scans, tag reports, share results, manage team roles, and audit entire sites or URLs from one workspace.
Education with due process
Use the Academic model, Moodle integration, and writing replay as investigative signals while preserving human review and an appeal process.
High-volume content platforms
Use the Enterprise API and larger credit allocation to incorporate AI and plagiarism checks into an existing content pipeline.
Capabilities
Core Originality AI features
Multiple AI detection models
Choose Lite, Turbo, Academic, or Multi Language based on the type of writing, allowed AI assistance, language, and false-positive tolerance.
Plagiarism detection
Finds matching, paraphrased, patchwork, mosaic, and other forms of copied content and links reviewers to potential sources.
Fact-checking aid
Identifies factual claims that may need verification and helps editorial teams reduce the risk of publishing unsupported statements.
Readability and grammar checks
Scores text against readability measures and flags spelling or grammar issues as part of the same review workflow.
Document, URL, and site scans
Accepts pasted text and common document files, scans individual URLs, and audits full websites for teams reviewing a large content library.
Google Docs writing replay
The Chrome extension can replay a document's writing process, show auto-typing signals, and generate shareable evidence alongside scan scores.
Deep Scan
Highlights passages that influenced the AI score and offers editing guidance intended to make writing more specific and natural.
Team and API workflows
Supports roles, tags, shareable and downloadable reports, scan history, additional seats, and Enterprise API access.
Process
How the Originality AI workflow works
Step 1
Define the content policy first
Document whether AI planning, editing, paraphrasing, or generation is allowed and choose a detector model that matches that policy.
Step 2
Scan a meaningful sample
Use the complete document when possible rather than a short excerpt; enable AI, plagiarism, or other checks based on the review objective.
Step 3
Inspect evidence, not just the score
Review highlighted passages, matched sources, factual claims, model choice, document length, and any Google Docs writing replay.
Step 4
Ask for context and corroborate
Discuss the result with the author, compare several samples, and account for editing tools, formulaic sections, citations, older text, or specialized academic language.
Step 5
Record a human decision
Use the scan as one input to a documented editorial or academic process; never treat an AI probability score as standalone proof of misconduct.
Cost
Originality AI pricing and free plan
Originality AI uses credits. One credit scans up to 100 words when running either AI detection or plagiarism; running both on the same 100 words uses two credits. Subscription credits reset and expire monthly, while separately purchased credits expire after two years. Limited free tools are available for evaluation.

Assessment
Originality AI strengths and limitations
Where it stands out
- Combines AI detection, plagiarism, fact-checking, readability, grammar, and site auditing in one review suite
- Offers different detection models instead of applying one sensitivity level to every policy and content type
- Writing replay and auto-typing evidence add useful process context beyond the classifier score
- Supports individual documents, URLs, full sites, Google Docs, Moodle, teams, and API workflows
- Publishes model testing and explicitly acknowledges false positives and the need for human judgment
What to consider
- AI detection is probabilistic and can produce both false positives and false negatives
- A high score does not show what percentage of a document was generated by AI and does not prove authorship or misconduct
- Short, formulaic, public-domain, academic, or heavily edited text can be more difficult to classify reliably
- Grammar tools, paraphrasers, and other AI-assisted editing can raise detection scores even when a person wrote the original draft
- Subscription credits expire at the end of each month and do not roll over
- Running AI and plagiarism checks together doubles the credits used for the same word count
- API access and 365-day scan history require the substantially more expensive Enterprise plan

Originality AI FAQs
What does Originality AI do?
It checks written content for AI-generation signals and plagiarism, and also provides fact-checking, readability, grammar, URL and site scans, writing replay, team reports, and an Enterprise API.
How much does Originality AI cost?
Pro costs $14.95 per month or $155.40 per year and includes 2,000 monthly credits. Enterprise costs $179 per month or $1,638.96 per year and includes 15,000 monthly credits plus API access and 365-day history.
How do Originality AI credits work?
One credit scans up to 100 words for either AI detection or plagiarism. Enabling both checks uses two credits per 100 words. Subscription credits expire monthly; separately purchased credits expire after two years.
Is Originality AI accurate?
Originality AI publishes strong benchmark results for its current models, but no detector is perfectly accurate. Results vary by model, language, text type, length, editing history, and the AI system being detected.
Can an Originality AI score prove that someone used AI?
No. The score is a confidence estimate, not proof and not the percentage of words written by AI. Originality AI itself says scores reflect probability rather than guilt.
Should schools discipline a student based on an AI score?
No. Originality AI advises against academic discipline based solely on detector output. Schools should review writing history, drafts, sources, policy, context, and the student's explanation through a fair process.
Which detection model should I use?
Lite fits policies that permit light AI editing, Turbo fits stricter no-AI policies, Academic is tuned for academic and STEM content, and Multi Language covers supported non-English languages. Validate the choice on your own known dataset.
Does Originality AI check Google Docs?
Yes. Its Chrome extension can scan Google Docs, generate shareable reports, replay the writing process, and show an auto-typing score for additional authorship context.
Bottom line
Our Originality AI verdict
Originality AI is a comprehensive content-integrity platform for teams that need repeatable AI, plagiarism, quality, and evidence workflows at scale. Its model choices and writing replay are useful differentiators, but the detector score must remain an investigative signal—not an automated verdict about a writer or student.
