Yseop Copilot
Yseop Copilot automates regulatory and medical writing for life sciences, drafting submission-ready documents inside Microsoft Word and Veeva Vault. Every sentence stays linked to its source data, with built-in audit trails for FDA and EMA review.
What is Yseop Copilot?
Yseop Copilot is a regulatory writing platform for the life sciences industry, published by the French company Yseop. It generates the documents that pharmaceutical companies file with health authorities, and it is built around one constraint: the output has to survive regulatory review, audit and approval, not merely read well.
Document coverage follows the eCTD modules. On the clinical side it produces clinical study reports, clinical trial narratives, summary clinical safety and summary clinical efficacy documents, investigator's brochures, informed consent forms, statistical considerations plans and lay summaries. On the preclinical and CMC side it covers pharmacokinetics reports and the quality overall summary. Each document type is handled by a configurable automation pack.
The platform organises work in three stages. Draft creates fully formatted documents from structured and narrative sources, grounding every sentence in the source data from the outset. Author lets teams lock sections, reuse approved content, validate against source changes and push a single update across documents, templates and regions. Finalize adds quality control, audit trails and formatting, then assembles the dossier for eCTD delivery.
Technically, Yseop describes a composite or neuro-symbolic approach: deterministic symbolic AI combined with large language models, supported by GraphRAG and small language models. Retrieval is deterministic, with the logic fixed at configuration time, and open prompts are deliberately refused so that outputs stay repeatable. Static agents follow predefined workflows while dynamic agents select tools, execute actions and validate results at runtime.
Writers work through a Microsoft Word add-in with one-click draft generation; administrators configure reports in a no-code Studio. The platform connects to Veeva Vault, to SDTM and ADaM datasets and clinical data repositories, and to Tableau, Qlik and Power BI.
Yseop claims deployment across top-ten global pharmaceutical companies and use in more than three hundred clinical trials, with named references at Eli Lilly, GSK and Sanofi. The company reports around ninety employees across offices in Paris, Lyon and New York, and was named to TIME's Best Inventions of 2025 in the medical and healthcare category.

Pricing & Plans
Yseop publishes no price. There is no permanent free plan and no free trial, and the pricing page returns a genuine error rather than a grid. In its FAQ the company describes itself as a SaaS vendor whose pricing model consists of an annual licence plus set-up costs, calculated on the number of users. No amount, currency or tier is disclosed, so an entry price cannot be stated. Professional services for the initial implementation are provided by Yseop's Customer Success team as part of the engagement.
Data, GDPR & hosting
A consolidated view of how Yseop Copilot handles your data.
GDPR overview
GDPR implementation is documented in concrete terms. Yseop states compliance with the GDPR, names an independent Data Protection Officer declared to the supervisory authority, and gives a single address for exercising rights, with a three-month maximum response time. The policy lists purposes and legal bases for the platform, the website and HR or marketing activity, sets a minimum age of fifteen, enumerates retention periods, and states that personal data is hosted exclusively on servers within the European Union. The CNIL is named as competent authority, with address and telephone number. Two limits matter. The published Terms and Conditions cover only the marketing website and are governed by English law, and no data processing agreement or subcontractor list is published. The Certified compliant by Dipeeo seal is a compliance provider's mark, not a certification of Yseop.
Who owns the data?
Yseop's privacy policy covers both the website and the Yseop Copilot platform. Personal data is processed only by Yseop's own teams and by technical subcontractors the company says it vets beforehand, for the sole purpose of operating the service. Yseop states that data is never sold and never shared with commercial partners, and that any sharing with subcontractors takes place under contractual safeguards. Each client sits on a single-tenant architecture, and a stateless mode is available in which customer data is not stored permanently. No subcontractor list is published and no data processing agreement is offered or mentioned anywhere on the site, so ownership of generated content cannot be confirmed from public documents.
Reuse rights
The Terms and Conditions published on the site govern the yseop.com website only, not the Copilot platform, and they say nothing about what a customer may do with generated documents. They do state that anything a visitor transmits through the website is treated as non-confidential and non-proprietary, and that Yseop is then free to reproduce, publish or otherwise use it. Site content is copyrighted, and the Yseop name, logos and trademarks may not be reused without written permission. Because no platform contract is public, the reuse rights attached to documents produced by Yseop Copilot are not documented anywhere on the site and would have to be settled in the commercial agreement.
Data retention & training
Hosting summary
Yseop states that personal data processed by its services is hosted exclusively on servers located within the European Union, and that it tries to use only technical tools whose servers are also in the Union, applying appropriate safeguards where that is not possible. No individual country is named, so the jurisdiction is stated at regional level only. The company describes itself as cloud-first and recommends hosting on the Yseop cloud. Each client is given a single-tenant architecture, with an optional stateless mode in which customer data is not stored permanently. Stated security measures include password encryption, delegated identity through single sign-on, encryption of the user database at rest and in transit, HTTPS, regular penetration testing and access traceability. No list of subprocessors is published. One distinction is worth keeping: the marketing website itself is served from an Amazon EC2 address in Ashburn, Virginia, which says nothing about where platform data lives.
Things to keep in mind
Risks and trade-offs to weigh before adopting Yseop Copilot.
- Automation bias: a draft that reads as authoritative invites lighter review, precisely where regulatory accountability cannot be delegated
- Skill erosion: writers who stop composing first drafts may lose the reasoning that makes them good reviewers
- Yseop's own framing, that output is a first draft for humans to finalise, is easy to forget under submission deadline pressure
- The performance figures quoted on the site come from the vendor or from customers it cites, and are not independently verified
- No platform contract, data processing agreement or subcontractor list is published, so data-handling commitments rest on a privacy policy alone
- The website's Terms and Conditions cover only the marketing site and are governed by English law, an unusual fit for a French publisher
- Company-history claims should be read carefully: the Yseop brand dates from 2007 while the legal entity dates from 2000, and the site elsewhere advertises a decade of impact
Setup & Integrations
Technical difficulty
Setup is an accompanied project, not a signup. The customer supplies text samples, writing guidelines, templates and mock datasets; Yseop assigns a project manager and runs three phases, initialization, configuration, then validation and deployment, which the company says take a few weeks. Day-to-day use is much lighter: no technical skill is required, writers work from a Microsoft Word add-in and reports are configured in a no-code Studio.

Should you pick Yseop Copilot?
Yseop Copilot is a narrow tool, and that is its argument. It does not try to be a writing assistant for everyone; it produces the specific documents that pharmaceutical companies file with health authorities, and it subordinates fluency to traceability, repeatability and auditability. The refusal of open prompts, the sentence-to-source linking and the deterministic retrieval logic are all consistent with that choice, and they are the reason the product fits a GxP environment where a general-purpose model does not.
The evidence behind it is unusually concrete for this market: named customers at Eli Lilly, GSK and Sanofi with attributed quotes, external recognition from TIME and the BIG Innovation Awards in consecutive years, and a company that has existed as a legal entity since 2000, trading under the Yseop name since 2007.
What a buyer should weigh is everything the site does not publish. There is no price, no pricing page, no self-service access, no platform contract, no data processing agreement and no subcontractor list. The Terms and Conditions on the site cover the marketing website alone and are governed by English law, which sits oddly with a French publisher. No certification is claimed with a number and a certifying body. Parts of the FAQ still describe an earlier product generation, including a free trial that does not exist and customer names from a finance offering the company no longer leads with.
The result is a credible enterprise product for regulated pharmaceutical writing, available only through a sales conversation and a multi-week implementation. Teams that fit the profile will find little else built this specifically for them; everyone else should look elsewhere.
