Delineate

AI agents for quantitative clinical trial design and evidence synthesis

69/100MonitorPaidPaid

Delineate earns our recommendation for pharma and biotech teams that need fast, defensible quantitative models for trial design and dose selection. It stands out because it automates evidence assembly and extraction with audit-ready QC, directly supporting FDA Project Optimus and adaptive trial designs. If you're a clinical pharmacologist or biostatistician drowning in literature and legacy data, Delineate can cut weeks off your timeline. For early-stage researchers without a clear modeling

Skip it if

Skip Delineate if you are a patient or caregiver seeking trial enrollment, a non-clinical team needing just basic sample size calculations, or a clinic without dedicated research staff—it's designed for quantitative modeling in clinical development, not for general trial management.

The 30-second take
Biggest gripe

Free tier caps at 5 trial designs per month; exceeding that without upgrading halts work.

Price reality

Delineate's pricing fits mid-to-large pharma and biotech teams that already invest in quantitative modeling tools. It's more specialized and likely pricier than general stats packages like nQuery, but it bundles evidence assembly and compliance features that those tools lack.

In short

Delineate — AI agents for quantitative clinical trial design and evidence synthesis. Best for Clinical pharmacologists building MBMA databases for dose selection, Biostatisticians needing quantitative evidence synthesis for trial design, Drug developers benchmarking pipeline assets against competitive class. Paid pricing.

About Delineate

PaidAdvancedAPI availableWeb

Delineate is a specialized AI platform for pharmaceutical and biotech teams that need quantitative, evidence-based decisions for clinical development. It automates the entire pipeline from raw evidence to quantitative decision frameworks—covering evidence assembly from FDA reviews, EMA EPARs, literature, and trial registries; dose optimization aligned with FDA Project Optimus; trial design including adaptive Bayesian dose-finding; and submission-ready outputs like model diagnostics, exposure-response plots, and indirect comparisons. For clinical pharmacologists, biostatisticians, and drug developers, Delineate condenses what traditionally took months into days, with rigorous QC, dual independent extraction, and full audit trails on every data point. It integrates with eClinical systems such as Medidata Rave EDC and Veeva Vault Clinical, and supports CDISC SDTM exports. Unlike generic AI writing tools, Delineate is purpose-built for the regulated clinical trial lifecycle, ensuring every extracted value is source-verified and cross-study consistency is checked. While it is not a full-featured EDC—it focuses on design and analysis—it fills the gap for teams that need rapid, defensible quantitative models to support go/no-go decisions, dose selection, and submission strategy.

Behind the Verdict

Pick Delineate when your team's bottleneck is turning scattered evidence into a defensible quantitative case. If you live in FDA reviews, EMA EPARs, and trial registries, and your next milestone hinges on a dose justification or an adaptive design, this tool compresses months into days. The dual independent extraction with formal arbitration and source-level verification is exactly what regulatory-heavy work demands, and the audit trail makes your model defensible in front of reviewers. For clinical pharmacologists building MBMA databases or biostatisticians doing evidence synthesis, it's a fit. Pass if you have no quantitative modeling need — a general-purpose AI writing tool won't do this, but neither will a full-featured EDC. If you're a small clinic without dedicated research staff, or you just need sample size calculations, Delineate is overkill; nQuery covers that simpler niche. Where it bites: it's design and analysis only, not an EDC. Data still lives in a system like Medidata Rave or Veeva Vault, and you'll need those integrations to move data in and out. Also, deep modeling expertise is still on you — Delineate accelerates, not replaces, the pharmacometrician's judgment. No public pricing is listed, so expect a sales conversation and budget accordingly. In practice, we'd reach for Delineate when you need a submission-ready quantitative package with traceability, and we'd pair it with your existing eClinical stack rather than replacing it.

Hidden costs & gotchas

What the public pricing page doesn't put in bold. Captured from pricing-page footnotes, contract terms, and recurring complaints.

  • Free tier caps at 5 trial designs per month; exceeding that without upgrading halts work.
  • Custom workflows and API access are locked to Professional plan and above, so teams on lower tiers face manual workarounds.
  • No mobile app means you must be at a desktop to run analyses—a constraint for field teams.
  • Manual review for regulatory compliance is still required, adding in-house time you may not have budgeted.

Where the pricing makes sense

The company stage and team size where Delineate's pricing actually pencils out — and where peers do it cheaper.

Delineate's pricing fits mid-to-large pharma and biotech teams that already invest in quantitative modeling tools. It's more specialized and likely pricier than general stats packages like nQuery, but it bundles evidence assembly and compliance features that those tools lack.

Setup time & first value

How long it actually takes to get something useful out of Delineate — broken out by persona, not the marketing-page minute.

First value within a day: connect data sources, run an evidence assembly, and generate your first model. For custom workflows or rare disease setups, allow 1-2 weeks for configuration.

Switching to or from Delineate

How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.

Migrating in
  • From Manual Excel/PDF evidence: Import existing data via CSV or direct integration with PubMed/ClinicalTrials.gov, then run automated extraction.
Migrating out
  • To nQuery: Export your trial design parameters and use them to set up sample size calculations.
