Originality.AI
Originality.ai is an AI detector that scores ChatGPT, GPT-5 and Gemini text, then adds plagiarism, fact-checking and readability checks in
Originality's reason to exist is defensibility: when you have to justify a flag to a client, an editor or an academic panel, published third-party accuracy research plus a Writing Replay beats a black-box percentage. The cost is credit math — Pro's 2,000 monthly credits equal about 200,000 words and expire each month, so heavy publishers top up or step up to Enterprise's 15,000. If you only scan occasionally, Basic's 3 free scans a day is genuinely enough; if you scan for a living, budget for

3 free scans · no card needed
Skip Originality.ai if your only need is occasional free detection on short text — Basic's 3 scans per day and 2,000-word cap will frustrate you, and a free detector covers that ground.
Subscription credits expire at the end of each month, so unused Pro or Enterprise volume is lost rather than rolled over.
For solo writers, freelancers and small editorial teams, Pro at $12.95/mo billed yearly (or $14.95/mo monthly) is priced above free detectors like GPTZero but below the seat-based cost of stacking a separate plagiarism checker and grammar tool. Agencies and publishers who scan continuously will outgrow Pro's 2,000 monthly credits and should budget for Enterprise at $136.58/mo billed yearly (or $179/mo monthly), which adds 15,000 credits, API access and 365-day history.

About Originality.AI
Originality.ai bundles AI detection with the rest of a publisher's pre-flight checklist. Paste text, upload a docx/pdf, type in the editor, or point it at a URL, and one scan returns an AI score, a plagiarism match report, readability, grammar, a Content Quality Score and a fact/hallucination check. Writers, editors, agencies and school integrity offices are the core audience, and the vendor courts them accordingly: the Chrome and Firefox extensions run scans inside Google Docs while recording a Writing Replay of the typing session, which is the artifact academic hearings and client disputes actually ask for. Accuracy claims are backed by published research rather than a lone benchmark. The company's 2026 study asserts 99%+ detector accuracy, and its October 2026 meta-analysis aggregates 16 academic detection studies. The detector is trained on adversarial data from text-rewriting tools, so it targets AI paraphrasing alongside raw model output, and the vendor lists coverage for GPT-6 Astra (Sol, Luna, Terra), GPT-5.5, Claude Fable 5, Gemini 3, Kimi K3, DeepSeek V4 (Flash & Pro), Grok 4.1 Fast, and Llama 4 Maverick & Scout. Two mechanics matter most in daily use. The AI Allowance threshold lets a team set how much machine assistance is acceptable and score against that bar, which fits hybrid human-plus-AI newsrooms better than a binary human/AI verdict. Deep Scan then explains why a passage was flagged and how to revise it. Enterprise and education accounts add team roles and seats, API access, 365-day scan history, shareable report links, PDF exports, a training-data opt-out and one-click scan deletion. Pricing runs from a free Basic tier at 3 scans a day to Pro at $12.95/mo billed yearly (or $14.95 monthly) and Enterprise at $136.58/mo yearly (or $179 monthly), with seats billed separately. The comparison buyers actually make is against Turnitin for academia and GPTZero for casual checks. Turnitin remains the LMS-native submission workflow; Originality.ai
Behind the Verdict
Buy Originality.ai for the paperwork, not for the thrill of a percentage. The detector is the headline, but what you're really paying for is a report you can hand to someone who is unhappy with your verdict: a Likely AI score, sentence-level highlights, plagiarism matches, a fact check, and on Google Docs a Writing Replay showing the text being typed. Publishers, agencies and integrity offices are the people who need that. Everyone else can probably stop reading. Pick it when the scan result has downstream consequences. A publisher vetting freelancer submissions, an agency running QA across a dozen client blogs, a school handling an authorship dispute — those workflows justify the price because the alternative is an argument you lose. The September 2026 AI Allowance setting is the feature I'd actually reach for first: setting a tolerance threshold and scoring drafts against it mirrors how hybrid AI-assisted newsrooms really operate, instead of pretending everything is either human or machine. Pass on it if your need is casual. Basic gives you 3 scans a day capped at 2,000 words per scan, which covers a curious writer and nothing else. And look hard at the credit model before subscribing: Pro's 2,000 credits equal roughly 200,000 words, they expire at month end, and rate-limited publishers burn through them faster than they expect. Top-ups exist, but they're a second invoice, and the jump to Enterprise's 15,000 credits at $136.58/mo billed yearly is steep for a two-person shop. Where it bites in practice: there is no collaborative editing inside the tool, so it slots into your workflow as a checkpoint, not a workspace. Teams standardized on Turnitin for LMS submissions will find Moodle and Google Classroom plugins useful but won't get Turnitin's native assignment pipeline. And no

Real-world workflow fit
Concrete scenarios for the personas Originality.AI actually fits — and what changes day-one when you adopt it.
You finish a draft in Google Docs with the Chrome extension installed and run a scan before sending it. The extension records a Writing Replay of the typing session, and the AI detector returns a sentence-level score.
Outcome: You send the client a shareable report link with the score and the writing replay attached, which settles the authorship question before it becomes a dispute.
You upload a batch of client drafts, tag each scan by client, and set an AI Allowance threshold per account so light AI assistance doesn't trigger a rejection.
Outcome: Drafts landing above the agreed threshold get Deep Scan notes and go back for revision; the rest clear review, and tagged scans keep each client's history separate.
You paste or upload submitted essays into Originality.ai, run AI detection and plagiarism together, and check Sentence Highlights on anything flagged.
Outcome: You get a defensible, sentence-level record for any integrity conversation, with a PDF report you can attach to the case file.
Use Cases
- Verify whether a freelance writer's submission is AI-generated before publishing
- Check plagiarism in student essays before grading

- Enforce a custom style guide with Guideline Checker before publication
- Prove your own writing is original using the Chrome extension's Writing Replay
- Set an AI Allowance threshold so hybrid human-AI drafts aren't auto-rejected

Plans compared
For each published Originality.AI tier: who it actually fits, and what it adds vs. the previous tier. Cross-reference the cost calculator above for projected annual outlay.
Basic
$0/mo
Ideal for
Someone testing the detector on a handful of short texts before committing, or a teacher spot-checking the occasional paragraph.
What this tier adds
Free entry point: AI detection only, 3 scans per day, 2,000 words per scan, with docx/pdf/doc upload and no subscription required.
Pro (Yearly)
$12.95/mo billed yearly ($155.40/year)
Ideal for
Individual editors, freelance writers and small teams who scan regularly and can pay for 12 months upfront to get the lower rate.
What this tier adds
Adds 2,000 monthly credits (1 credit = 100 words) and the full all-in-one scan set — plagiarism, readability, grammar, fact-check, content quality, Guideline Checker — plus URL scans, Chrome extension with Google Docs writing replay, team management and scan tagging. Additional
Pro (Monthly)
$14.95/mo
Ideal for
Small teams and freelancers who want the full all-in-one toolset without a 12-month commitment.
What this tier adds
Same feature set and 2,000 monthly credits as yearly Pro, at $14.95/mo instead of $12.95/mo billed yearly, with additional seats at $9.95/mo and cancel-anytime terms.
Enterprise (Yearly)
$136.58/mo billed yearly ($1,638.96/year)
Ideal for
Agencies, high-volume publishers and schools running continuous QA across many clients or students.
What this tier adds
Raises the allowance to 15,000 monthly credits and adds API access, 365-day scan history, priority support typically under an hour, a dedicated Customer Success Manager and report sharing without granting account access. Additional seats $19.04/mo.
Enterprise (Monthly)
$179/mo
Ideal for
The same agency, publisher or school profile that needs Enterprise volume but cannot commit to an annual contract.
What this tier adds
Matches yearly Enterprise on credits, API access, 365-day history, priority support and CSM, at $179/mo, with additional seats at $24.95/mo.
Where the pricing makes sense
The company stage and team size where Originality.AI's pricing actually pencils out — and where peers do it cheaper.
For solo writers, freelancers and small editorial teams, Pro at $12.95/mo billed yearly (or $14.95/mo monthly) is priced above free detectors like GPTZero but below the seat-based cost of stacking a separate plagiarism checker and grammar tool. Agencies and publishers who scan continuously will outgrow Pro's 2,000 monthly credits and should budget for Enterprise at $136.58/mo billed yearly (or $179/mo monthly), which adds 15,000 credits, API access and 365-day history.
Setup time & first value
How long it actually takes to get something useful out of Originality.AI — broken out by persona, not the marketing-page minute.
Solo writers reach first value in about five minutes: install the Chrome extension, run one scan in Google Docs, and read the score. Editors setting up team roles, scan tagging and a custom Guideline Checker should budget 30–60 minutes. Enterprise API embedding takes developer time to wire into a CMS or grading pipeline, and the API docs were not part of this scrape, so plan a discovery step.
Switching to or from Originality.AI
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From GPTZero: run the same sample texts through both detectors, then move your standing checks to Originality.ai once you've compared sentence-level flags.
- →From a separate plagiarism checker plus grammar tool: consolidate both into one all-in-one scan on Pro, which covers AI detection, plagiarism, readability and grammar in a single pass.
- →From manual Google Docs review: install the Chrome extension so scans and Writing Replay run inside the documents your team already edits.
- →From Turnitin: keep Turnitin for LMS-native submission and add Originality.ai for AI-detection depth, Guideline Checker and writing-replay evidence.
- →From spreadsheet-based QA logs: move to Pro's scan tagging and shareable report links so each review is stored with its client or student record.
- ↗To GPTZero: export flagged samples and re-run them on GPTZero if you need a free or lower-cost detector for casual checks.
- ↗To Turnitin: route graded submissions through your LMS-native Turnitin workflow if institution policy requires it.
- ↗To a general-purpose LLM: fine for rough AI-content guesswork, but you lose the plagiarism scan, readability scoring and shareable evidence reports.
- ↗To Grammarly plus Copyscape: rebuild a grammar-plus-plagiarism stack if you no longer need AI detection or Guideline Checker enforcement.
- ↗To a manual editorial review: drop the tooling entirely, but you also give up the defensible scan record that supports authorship disputes.
