About

Medical expertise, applied to everyday workflows

Dr. Prashant Patel is a physician with an MD in Pharmacology and more than nine years in the pharmaceutical industry across pharmacovigilance, regulatory affairs and medical affairs.

Much of this work depends on dense documents: clinical study reports, SmPCs, patient information leaflets and regulatory submissions. Available tools are often costly, generic, or require confidential material to be uploaded to external servers.

These tools address specific gaps encountered in practice. Each runs entirely in the browser, with no installation and no data leaving the user's device.

Philosophy

Why build this way

Three constraints shaped every decision.

01

Privacy by default

Regulatory and clinical documents are confidential. Tools that require uploading them create avoidable risk, so everything here is processed locally within the browser.

02

No installation

No software installation, licences or IT onboarding. Each tool is a single page that can be bookmarked and used immediately.

03

Built from practice

Features reflect real working requirements, such as column-aware comparison for multi-column SmPCs, and prioritisation shaped by how medical and regulatory deliverables are managed.
