Your team is working on
Million $$$ documents in Word.

The average Phase III CSR takes 6–12 weeks of medical writing time. It lives in shared folders, email chains, and a reference library no one can fully search. When the draft goes to QA, the audit trail is a timestamp on a file name.

That's not a workflow. That's a liability.

Why ProWriter

AI that knows what an FDA reviewer expects to read.

ProWriter isn't a general-purpose AI writing assistant with a regulatory skin on top. It's a purpose-built workspace where every template, every model, and every citation rule was designed for ICH E3 and FDA submissions from day one.

Grounded. Not guessing.

Every sentence ProWriter generates is sourced from documents you upload, your study reports, amendments, SAPs, and reference literature. If a claim has no source in your library, ProWriter won't write it. No hallucinations. No invented citations. No surprises in QA.

Compliant by architecture, not by policy.

HIPAA-grade infrastructure. End-to-End Encrypted. 21 CFR Part 11 audit trail built into every document and notebook entry. Your IT and compliance team won't need to build a risk framework around ProWriter, we already built it for them.

Faster than any other tool your team has tried.

Industry pilots show AI-assisted regulatory writing cuts CSR drafting time by up to 40–87%. ProWriter customers report saving a median of 87% of time per section, with a draft that doesn't need to be rebuilt from scratch.

Case study · CAR-T / AML

87% less drafting and review time per CSR section.

A biopharma team developing CAR-T cell therapy for AML compared ProWriter with its in-house workflows, manual drafting and a generic AI tool, across five ICH E3 CSR sections. Each section was timed from reference gathering to hand-off for CMO sign-off, human review included.

One company, five CSR sections, March 2026; four participants (the client's CMO, senior and associate medical writers, plus a ProWriter medical writer, who drafted the ProWriter versions). The client's senior medical writer ran QA/QC and the CMO signed off every version. Not a controlled trial. Redaction time is excluded, and generic AI tool times are approximate, as reported by the client's team. Customer name withheld on request.

How it works

From reference library to submission-ready draft, in hours, not weeks.

Open a template.

Choose from 40+ templates shaped to ICH E3, FDA, journal standards and more. Each template carries its own section structure, voice instructions, and grounding rules.

Upload your library.

Drag in your study reports, protocols, prior submissions, SAPs, and literature. ProWriter organizes them into a searchable, citable reference library that's scoped to your project and never shared with other users.

Draft, review, lock, submit.

Generate sections grounded in your library. Review with your team using role-based access. Export to .docx or PDF. Every change logged in an immutable audit trail.

Built for regulatory science

Built for regulatory science.
Not adapted from a general-purpose AI.

ChatGPT, Copilot, and general AI assistants are not HIPAA-compliant by default, are not grounded in your reference library, do not understand ICH E3 structure, and cannot produce an audit trail. They are powerful tools, for tasks that don't go to an FDA reviewer.

ProWriter was built specifically for the documents that do.

Trust

Your data is protected. Always.

Three commitments, none of them aspirational, all of them audited.

Encryption

Industry-standard encryption.

Your data is encrypted at rest (AES-256) and in transit (TLS 1.3). We perform regular third-party security tests to ensure best industry standard encryption.

Training

No model training, ever.

We never use your inputs or outputs to train models. Your IP, methods, drafts, raw data stays yours. Contractually and architecturally.

Sharing

No data sharing.

AI chat records are deleted when you navigate away from a document. We don't sell, rent, or share user-uploaded data with third parties.

Pricing

Simple, transparent. Try before you commit.
