Certara CoAuthor: The GenAI Writing Copilot That Cuts Regulatory Submission Timelines by 30%

Certara CoAuthor is a purpose-built generative AI platform for regulatory and medical writing that helps life-sciences teams draft, review, standardise, and manage complex submission documents. Within the Regulatory Automation – Document Review and Authoring category, it supports regulated writing workflows for documents such as clinical study reports, patient narratives, protocols, synopses, toxicology reports, and other clinical and regulatory content.

As a medical writing efficiency solution, CoAuthor combines a life-science-specialised GPT with structured content authoring, a permissions-governed content repository, and a library of more than 275 eCTD templates. It can help writers generate and refine source-grounded text and data summaries, reuse approved content consistently across study documents, automate formatting, hyperlinking, and metadata tasks, and collaborate through controlled review workflows in Microsoft Word. This reduces repetitive drafting and manual document-production work while leaving interpretation, scientific judgement, and final approval with qualified human reviewers.

Certara reports that CoAuthor can deliver up to 40% productivity improvement for drafting and QC of document sections, and that individual writers have reported a 2.25-fold efficiency gain when drafting content. The company also cites submission teams that reduced document-development timelines by more than 20% when using relevant CoAuthor capabilities. These figures are vendor-reported and should be interpreted in the context of the document type, source-data availability, implementation model, and required review process.

CoAuthor addresses the operational burden of maintaining consistent, high-volume submission content under tight timelines. Instead of relying solely on manual drafting, formatting, version reconciliation, and repeated reuse of the same approved information, teams can work from structured content, organisation-specific templates, and authorised source material. Its Microsoft Word integration, real-time collaboration, version control, traceability, and content-reuse features help writers spend less time on repetitive document-production tasks and more time contextualising data, developing key messages, and completing expert review.

By embedding AI directly into document workflows, Certara CoAuthor can shorten authoring cycles and lower the administrative burden on subject‑matter experts. Teams can reallocate time from formatting, cross-checking, and text assembly to higher-value analytical and strategic tasks, while maintaining a coherent narrative and structure across related documents. In practice, this can speed up documentation through internal review and governance, and help organisations use their medical writing and regulatory operations capacity more efficiently.
