Billing and plans
The four plans and what each includes, how usage is counted, and managing your subscription through Stripe.
Plans
| Plan | Price | Included |
|---|---|---|
| Free | $0 | 3 checks / month · 2,500 words per check |
| Pro | $23 / month | 50 checks / month · 25,000 words per check · Noplag Database |
| Premium | $79 / month | 200 checks / month · 50,000 words per check · Live Web search + Noplag Database |
| Enterprise | Custom | Custom volume · all corpora · priority support · invoicing |
Premium and Enterprise include the live-web layer — matching against freshly fetched web content at check time, not just the indexed corpus.
How usage is counted
Your plan includes a number of checks per billing period. The billing page shows checks used versus included for the current period, with a 30-day activity chart. A failed check doesn't silently consume your quota.
No surprise bills
When you reach your plan's limit, new checks are blocked until the period resets or you upgrade — you're never billed for overage automatically.
Upgrading and managing your subscription
Everything runs through Stripe:
- Upgrade from Settings → Billing; payment details are collected in Stripe Checkout.
- Manage subscription opens the Stripe customer portal — change plan, update the payment method, or cancel there.
- Invoices are listed on the billing page.
- Cancelling stops future renewals; you keep the plan until the end of the paid period.
For Enterprise (custom volume, invoicing), contact enterprise@noplag.com.
The Noplag API
Pro and Premium plans include API access for running checks programmatically. API checks run the same pipeline as in-app checks.
