Pangram Labs
AI text detection for ChatGPT, Claude and Gemini output, plus AI image and video checks — built to survive a dispute
For anyone who might have to justify an accusation, Pangram is the detector I'd put my name behind. Segment-level output plus a published false-positive rate matters more than a single confidence number when a student or a contributor pushes back on the result. Run the math on your word volume before you commit a whole department to it.

Skip Pangram if you need forensic certainty on AI-generated images — its image detector is a research preview, and the vendor documents that locally edited AI images are flagged as fully AI.
The Individual plan's 300,000-word monthly cap goes fast across a large course or a busy submissions desk, and the jump to get 5x the words is the $65/mo Professional plan
$20/mo for 300,000 words and 100 image scans undercuts what most institutions already pay for a single-seat plagiarism checker, and $40/mo for 2 seats keeps a small honor council inside budget. The $65/mo Professional plan is the honest entry point for a department: 5x the words plus $200/mo of bundled API credits, which is cheaper than buying Individual plus API credits separately.

What is Pangram Labs?
Pangram Labs — AI text detection for ChatGPT, Claude and Gemini output, plus AI image and video checks — built to survive a dispute. Best for University honor councils and professors who need segment-level evidence to support a ruling, Publishing and media desks screening contributor submissions and press releases at volume, HR and recruiting teams checking application materials for machine-written text.

Pangram is an AI detector for people who have to defend the call they make about a document. Universities, publishers, editors, recruiters and compliance teams run writing through it to separate human work from machine output, and the accuracy argument isn't vendor-only: researchers at the University of Chicago and University of Maryland have verified it, and Pangram publishes per-model benchmark results on a public model card against 26 models. The vendor claims accuracy above 99% on those AI-generated samples and retests on every major model release. The current engine is Pangram 4, with a migration guide for teams moving off older versions published in August 2026. Text detection covers 20+ languages and is built to catch humanized or paraphrased text that slips past other checkers. Three features do most of the differentiating: AI Segment Analysis shows how much of a document is machine-written rather than just a confidence score, AI Assistance Detection highlights passages a human edited with AI rather than generated outright, and the Similarity Checker runs plagiarism and AI detection in a single scan. Detection now spans three modalities. Image Detection (the Image 1.0 model) is live for JPG, PNG and WebP files at 512×512px minimum and up to 30 MB, and Video Detection accepts MP4, MOV and WebM up to 500 MB. Every plan carries a documented false-positive rate, and the free checker gives 20 credits daily. Workflow reach is broad: a Chrome extension, Gmail integration, Google Docs add-on, LMS plugins for Canvas, Google Classroom and Brightspace, an MCP server, and API access with realtime and bulk endpoints. Uploads take PDF, DOCX and RTF with OCR, up to 100 files at once. Against GPTZero and Originality.ai, the pitch is the audit trail — segment highlights, a public model card, and a methodology you can hand to a disciplinary committee.

Behind the verdict
Where Pangram earns its keep is in the dispute, not in the clean case. A professor staring at a paper that reads like ChatGPT doesn't need a percentage — she needs the sentence-by-sentence breakdown she can paste into an honor-council packet. That's AI Segment Analysis, and paired with the false-positive claim on the site it's the most defensible story on the market right now. Publishing desks should look at the numbers Pangram published in September 2026: it scanned 178,672 PR Newswire releases and found AI-generated text in 34% of them over the past year, climbing to 48% by June 2026. If your team fields press releases or freelancer pitches, that is your workload, and the Similarity Checker that also runs plagiarism in the same pass saves a second tool. Budget carefully. Individual is $20/month for 300,000 words and 100 image scans — fine for one editor, thin for a course of 200 students. Professional at $65/month gives 5x the words, 5x the image scans and $200 of monthly API credits, which is the tier most departments actually want once they've done the arithmetic. Team at $40/month for two seats ($20/seat) adds admin and billing controls. Where it bites: image and video detection are newer, and Pangram's own September 2026 explainer says locally edited AI images come back flagged as fully AI. Treat visual output as directional, not forensic. And no detector — this one included — is a verdict machine; the evidence still needs a human reading it. Against GPTZero, the difference is the audit trail and the verified benchmarks tied to named model versions with test dates. If you want a cheap confidence score for casual scanning, Pangram is more machinery than you need. If you need the report to hold up in front of a committee, it's the one I'd reach for.

Outcome: Submissions get an AI and plagiarism score on arrival, and the $200 of monthly API credits bundled with the Professional plan covers early traffic before you need to add credits.

Switching to or from Pangram Labs
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From GPTZero: re-run a sample of documents you already scored so you can compare segment-level output against GPTZero's single percentage before you switch the whole workflow
- →From Originality.ai: move plagiarism screening across with the Similarity Checker, which returns AI and similarity results in one scan instead of two tools
- →From Turnitin's built-in detector: keep Turnitin for the submission workflow and run Pangram as a second opinion where you need citable evidence
- →From Pangram 3: the vendor published a Pangram 4 migration guide covering the move to the current detection model
- ↗To GPTZero: if you only need a top-line percentage and a familiar interface, and don't need segment-level evidence, reconfigure your review workflow around its score display
- ↗To Originality.ai: if plagiarism screening is your primary need and AI detection is secondary, consolidate on a plagiarism-first tool
- ↗To Turnitin: if you need detection fused into an existing institutional submission and grading system rather than a separate portal
