## Ways to pay less

- **Save $60 to $240 a year with annual billing** (Annual discount): Individual is $15 a month billed annually against $20 monthly (save $60), Professional $45 against $65 (save $240), and a 2-seat Team saves $120. Source: https://www.pangram.com/pricing

## Key features

- **AI text detection:** Scores a text for AI generation and marks AI-written or AI-assisted segments; Pangram benchmarks it against 26 models from OpenAI, Anthropic, Google and others.
- **AI image detection:** Checks JPG, PNG or WebP images of at least 512 x 512 pixels for AI generation: 3 a day free, 100 a month on Individual and 500 on Professional.
- **Similarity checks:** Paid plans can run a similarity (plagiarism) check on any scan; each one uses 5 credits, or 500 words of allowance.
- **Chrome extension and feeds:** The Chrome extension checks text in the browser, and on paid plans it automatically scans your feeds on social media, Substack and similar sites.
- **Docs, Gmail and school systems:** Paid plans add Google Docs and Gmail; schools connect it to learning systems such as Canvas, Moodle, Google Classroom and Brightspace.
- **Developer API:** A pay-as-you-go API costs $0.05 per 100 words, with 20% off for batch submissions sent asynchronously.

## Good for

- Teachers and professors checking student work for AI writing
- Editors and publishers screening submitted articles
- Developers adding AI detection to their own apps through the API

## Worth knowing

- The free plan stops at 20 credits a day: one credit is 100 words, rounded up, so it covers about 2,000 words. Credits reset daily.
- API use is billed apart from the seat plans at $0.05 per 100 words; of the self-serve plans, only Professional includes API credit.
- Refunds apply only to individual plans, within 14 days of purchase and with fewer than 20 credits used.
- Zero data retention, custom hosting and custom LMS or ATS integrations need the sales-priced Enterprise plan.

## ToolGPA grades

**GPA: 2.6 out of 4**, graded Oct 18, 2026. Pangram tells you whether a piece of text was written by ChatGPT, Claude or Gemini, and marks which passages look AI-written or AI-assisted, in more than 20 languages. It checks images too. The free 2,000 words a day goes a long way, but it doesn't help you write anything, it only checks.

- **Value for money: C.** Graded against its own alternatives, as it checks text rather than helping you write it. Individual is $15 a month billed yearly ($20 monthly) for 300,000 words, above Grammarly's and Paperpal's $12 and nearly twice QuillBot's $8.33, which all do more besides.
- **Free plan and trial: B.** Free for good with no payment method: 20 credits a day, about 2,000 words, plus 3 image scans, and it resets daily. One person checking the odd essay or article could live on that. A teacher marking a whole class in an evening couldn't.
- **Features: C.** It does AI detection fully: scores and marked passages across 20+ languages, image checks, similarity checks, OCR for scanned files and feed scanning. But it's a much smaller job than a writing tool's, as it only tells you who wrote the text.
- **Ease of use: B.** No store rating on record, but there's nothing to set up: paste the text or upload a file, and the result comes back with the suspect passages marked.
- **Platforms and integrations: B.** Web and a Chrome extension, with Google Docs and Gmail on paid plans, Canvas, Moodle, Google Classroom and Brightspace for schools, and an API. No desktop or phone app.

## Keep it, or make your own?

**You could make this.** A writing app at its plainest is a page that saves what you type. What Pangram does at its core is plain work, and that is the kind of thing an AI app builder makes well. You would give up 2 things, listed below, and little else. It costs $180 a year. An AI app builder starts at about $19 a month on our listings, and you only need it while you build.

- You could make: It runs in a browser, which is where something home-made would run too.
- You could not: It plugs into other products, Google Docs, Gmail and Canvas among them, and has an API.
- You could not: AI features, unless you pay a model provider for each request yourself.
