Ciroapp score

4.3/ 5

Pangram backs its accuracy claims with independent research from the University of Chicago and University of Maryland, plus a documented 1-in-10,000 false positive rate. Segment-level reports show exactly what's AI, but plagiarism checks sit behind paid plans and no money-back guarantee is advertised. Overall, it's a strong pick for educators, publishers, and developers who need results they can defend.

Pros

  • Pros:Accuracy is independently verified, not just claimed — researchers at the University of Chicago and University of Maryland found Pangram posted the lowest false positive rates against competing detectors, with a documented 1-in-10,000 false positive rate measured across tens of millions of human-written documents.
  • Pros:Segment-level analysis goes beyond a single score by highlighting exactly which parts of a document are AI-generated versus AI-assisted, so mixed human-and-machine writing can be explained with concrete evidence.
  • Pros:Model coverage stays current — Pangram benchmarks against 26 models including ChatGPT, Claude, Gemini, Grok, DeepSeek, and Llama, retests on every major model release, and catches text run through 'humanizer' evasion tools.

Cons

  • Cons:Plagiarism detection is locked behind paid plans — free users get AI and image detection only, and free image checking is capped at just 3 scans per day.
  • Cons:Even the free tier requires creating an account, and no money-back guarantee is advertised; refunds beyond the 7-day trial on Individual and Team plans aren't stated.
  • Cons:Integration support is limited to a specific list (Chrome, Firefox, Google Docs, Canvas, Google Classroom, Moodle, Brightspace), so teams on other LMS platforms or editors should confirm compatibility before committing.
Best for
  • Teachers and professors who need reliable AI checks on student writing
  • Universities rolling out AI policies through an LMS like Canvas or Google Classroom
  • Publishers and platform teams moderating large volumes of user-generated content

What is Pangram Labs?

A false positive from an AI detector can cost a student their grade or a writer their reputation. That's the core problem Pangram attacks. It offers independently verified accuracy, a documented 1-in-10,000 false positive rate, and segment-level results that show exactly how much of a document is AI-generated or AI-assisted.

Pangram is an AI content detection tool for text and images. It flags writing from models like ChatGPT, Claude, Gemini, Grok, and Llama, shows how much of a document is AI, and highlights sections edited with AI assistance. It also includes plagiarism checking.

It's built for teachers, universities, publishers, enterprises, and anyone who needs to verify written work is human.

Should you choose Pangram Labs?

Quick buyer guidance before you compare plans or click through.

Choose it if

  • Buyers who want third-party verified accuracy before acting on a flag
  • Multilingual teams — detection covers 20+ languages, from Spanish and French to Chinese and Arabic
  • Anyone handling documents at scale — upload PDF, DOCX, or RTF files, up to 100 at a time
  • Organizations with security requirements — SOC 2 Type 2 verified, encrypted storage, and no data sharing or selling
  • Educators who want students to see the same detailed report their instructor sees

Skip it if

  • You need more than 20 free checks a day — additional credits and plagiarism detection require a paid subscription
  • You'd rather not create an account — even the free tier requires signup
  • Your workflow depends on platforms outside the listed integrations (Chrome, Firefox, Google Docs, Canvas, Google Classroom, Moodle, Brightspace) — confirm support before committing
  • You only scan images occasionally — free image checking is capped at 3 scans per day

Next steps before buying

  1. 1Create a free account and test it on writing you already know the origin of — you get 20 checks per day.
  2. 2Open Pangram's model card to check accuracy numbers for the specific AI models you care about.
  3. 3Confirm the integration you need — Chrome or Firefox extension, Google Docs, or an LMS like Canvas — before rolling it out to a team.
  4. 4Run the same sample through an alternative detector to compare results before you commit.

Ease of use

On the web app, you paste text or upload files and get scores with highlighted sections — no setup required. Browser extensions put checks one click away, and LMS integrations bring reports into Canvas or Google Classroom. Past scans stay in your history for review and download. The workflow looks straightforward for non-technical users, and the API covers automation needs.

Pangram Labs Key Features

✨ See exactly what's AI, segment by segment

Pangram doesn't stop at a score. It breaks your document into segments and shows how much is AI-generated or AI-assisted. Sections edited by AI are highlighted separately from text written from scratch. That's useful when a document mixes human and machine writing — you see exactly where, and you can explain the result with evidence.

✨ Accuracy that holds up under scrutiny

Results you can defend. Independent researchers at the University of Chicago and the University of Maryland tested Pangram against other detectors. It posted the lowest false positive rates and beat trained human readers at spotting AI text. Its documented false positive rate is 1 in 10,000, measured across tens of millions of human-written documents.

✨ Trained on the latest models, ready for the next one

AI models change fast. Pangram is trained specifically on frontier models like ChatGPT, Claude, Gemini, Grok, and Llama, and it benchmarks against 26 models. It retests on every major model release and even catches text processed by 'humanizer' tools.

When a new model ships, the detector updates — you're not stuck with stale results.

✨ Text, images, and plagiarism — checked together

Not everything you check is text. Pangram also detects AI-generated images — upload a JPG, PNG, or WebP file to scan it. It pairs AI detection with plagiarism checking, so one scan covers copied content and machine writing together.

You get the full picture of a document's origin in one place.

🧩 Fits the tools you already use

You don't have to change how you work. Paste text or upload files — PDF, DOCX, RTF, up to 100 at a time — and past scans stay in your history to review or download. Use it wherever writing happens:

  • Chrome and Firefox browser extensions
  • Google Docs integration
  • LMS support for Canvas, Google Classroom, Moodle, and Brightspace

Use Cases

🎓 Fair grading for teachers

A teacher pastes an essay or uploads files and sees which sections are AI-generated or AI-assisted. The documented 1-in-10,000 false positive rate means a flag starts a conversation, not a verdict. Expected outcome: fairer grading, backed by evidence.

🏫 Campus-wide AI policies

Rolling out an AI policy? Pangram works inside Canvas, Google Classroom, Moodle, and Brightspace. Professors check work without leaving their LMS, and integrity teams get segment-level evidence. Expected outcome: consistent enforcement at scale.

Tip: Confirm your LMS is supported before rolling it out campus-wide.

🛡️ Moderation at scale

Running a platform full of user submissions? Use the API or feed scanning to catch AI content automatically. LessWrong's CTO reports it pays for itself many times over.

Expected outcome: less manual review, more authentic communities.

💻 Detection in your product

Building AI checks into your own app? The usage-based Developer API starts at $25, with a 20% bulk discount as volume grows. You get verified accuracy without training a model yourself.

Expected outcome: reliable detection, live from day one.

Why use Pangram Labs?

Most AI detectors ask you to take a score on faith. Pangram backs its claims with published research. Third-party evaluations from the University of Chicago and the University of Maryland found it outperformed competing detectors — and even trained human readers — at spotting AI text. If you need results you can defend, that's the difference.

  • Verified accuracy, not just marketing. Independent researchers tested Pangram against tools like GPTZero and Originality.ai. Pangram posted the lowest false positive rates across product reviews, blog posts, news articles, and more.
  • A documented 1-in-10,000 false positive rate. Pangram calculates this across tens of millions of human-written documents, so a wrong accusation is far less likely.
  • Explanations, not only scores. Segment analysis shows how much of a document is AI. Assistance detection highlights parts that were edited with AI rather than written from scratch.
  • Coverage that stays current. Pangram benchmarks against 26 models — including ChatGPT, Claude, Gemini, Grok, DeepSeek, and Llama — and retests on every major model release.
  • It fits your workflow. Chrome and Firefox extensions, a Google Docs integration, LMS support for Canvas, Google Classroom, Moodle, and Brightspace, plus an API for high-volume projects.
  • A real free tier. You get 20 checks per day, and image detection includes 3 free scans daily, so you can test it on your own documents first.
