Comparison · incumbent feasibility & intelligence vendor
A cited, auditable Citeline alternative.
Citeline (Norstella) is a deep, well-established intelligence suite. If what you need from feasibility is a fast, fully-cited, re-runnable verdict you can white-label into a bid and defend line by line, here is how we compare.
| Capability | Citeline | Clinical AI OS |
|---|---|---|
| Typical turnaround per protocol | Varies (often days to weeks) | Hours |
| Every number cited to a public source | ||
| Deterministic, re-runnable scorers | ||
| 21 CFR Part 11 tamper-evident audit chain on every run | ||
| White-label + run in your own cloud account | ||
| Self-hosted inference — protocols never sent to a third-party model | ||
| Pricing model | Enterprise / subscription | Per-run + platform plan |
Where Citeline is strong
Citeline brings a large proprietary intelligence dataset, investigator and site databases, and a long track record across the industry. For broad market intelligence beyond a single feasibility verdict, that breadth is real.
Where we differ
- Every figure in the verdict links to its public-source record (ClinicalTrials.gov, AACT, PubMed, FDA, EMA, Open Targets, ChEMBL) with a snapshot date — not a proprietary black box.
- Deterministic scorers: the same inputs and snapshot reproduce the same verdict months later, which is what makes it defensible in a sponsor review.
- A 21 CFR Part 11 hash-chained audit bundle on every run, exportable for your QA team.
- White-label and dedicated-cluster mode so a CRO can resell the output under its own brand.
