1 credit = 1 paper. Transparent pricing, earning free credits, and subscription plans.
10 · Credits & pricing
One credit = one paper. That's the whole formula — however many fields your schema has, however many records a paper yields, processing one paper costs one credit.
Earning credits (free)
| Action | Credits |
|---|---|
| Create an account | +100 |
| Complete your profile | +50 |
| Share Sci-database on social media (once) | +50 |
A new account can reach 200 free credits without paying anything; the free tier is advertised as 150 papers (signup + profile).
Spending credits
| Action | Cost |
|---|---|
| Process a paper (extraction) | 1 per paper |
| Resume a job | 1 per unfinished paper only |
| AI schema suggestion (Suggest Parameters) | 2 |
| Cross-validation (system key) | 2 per sampled paper (or FREE with your API key) |
| Investigate a discrepancy (AI Judge) | 1 |
| Improve Schema (AI description rewrite) | 1 |
Searching, uploading, queueing, browsing, exporting, and sharing are always free.
When your balance drops below 10 credits you get a one-time low-credit email alert. If an action would exceed your balance, it simply doesn't run — you're never billed into the negative.
