Originality.ai vs Pangram (2026): which should you pick?

Pick Originality.ai if

• Fits if you check many articles and want bulk scans
• Works for content teams that need scan history and extra seats

Look elsewhere if

• Pricey if you want the API, listed on Enterprise at $136.58 a month
• Watch out: extra seats cost extra on both paid plans, and pay-as-you-go credits expire after two years

Pick Pangram if

• Fits if you're a teacher checking whether an essay was written by the student
• Works for editors screening submitted articles before they run

Look elsewhere if

• Skip it if you want help writing, as it only checks what's already written
• Tight if you mark a whole class on the free plan, at about 2,000 words and 3 image scans a day
• Pricey if you scan in bulk through the API, at $0.05 per 100 words once Individual's $10 of monthly API credit runs out
• Watch out: refunds are for individual plans only, within 14 days and with fewer than 20 credits used
• Watch out: Team starts at 2 seats, Professional is billed at sign-up, and zero data retention needs sales-priced Enterprise

Originality.ai

• Credits are metered: 1 credit equals 100 words, and Pro credits expire at the end of each month.

• The Free plan's allowance appears twice on the pricing page with different figures.
• API access is listed only on Enterprise, and extra team seats cost extra on both paid plans.

Pangram

• 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 plans at $0.05 per 100 words, $0.25 per image and $0.05 per second of video; Individual includes $10 of API credit a month, Professional $200.
• 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.
