Pricing Comparison
Pricing can change, so treat the comparisons below as a guide. Always check each vendor's website before purchasing.
- DupliChecker — Offers a free tier suitable for occasional or one-off checks, with daily or per-check limits. Paid plans remove limits and add extra features like more checks per day, but feature scope is focused on plagiarism and basic SEO tools.
- Rephrasely — Provides a free tier for trial and light use, plus monthly and annual subscriptions that scale limits and unlock advanced tools like Composer (AI writer), batch plagiarism checks, team seats, and API access.
Actionable advice: If you run frequent large-volume checks or need team features, compare the maximum words-per-month and API limits more than headline prices. Rephrasely's subscriptions are structured to reduce per-word cost at higher tiers and include tools that replace separate subscriptions (paraphraser + AI writer + detector).
