Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.
| AI agent — with a subscription (Claude Pro/Max, Cursor, etc.) | $0 marginal |
| AI agent — pay-per-use API, no subscription | $16–$27 one-time |
| Hosting, once it's running | $0/mo (free tier) |
| Domain name, if you want your own | ~$12/yr |
Originality.ai costs $14.95/mo. Even paying per-token with no subscription, and accounting for hosting, this build pays for itself in about 2 months.

Originality.ai costs $14.95/mo (about $179/yr) as of 2026-08. That's what a working rebuild would save you.
The underlying detection models (both AI-content and plagiarism) are genuinely hard ML/search-index problems — you're integrating existing ones, not building your own API costs scale with usage and volume, so real traffic needs a pricing plan of your own Detection accuracy is inherently probabilistic and improves with whichever underlying model you choose, not your own code
