1. Grammarly

Grammarly is relied upon by more than 50,000 organizations and 40 million people globally. While it isn’t exclusively designed for medical use, its GrammarlyGO Medical module includes specialized medical dictionaries. These tools help healthcare professionals verify dosage information, check the accuracy of medical terminology, and maintain consistency in drug names.

Medical Terminology Accuracy

The standard version of Grammarly might flag correct medical terms as errors or overlook intricate technical mistakes. These issues can be addressed by upgrading to GrammarlyGO Medical. For organizations, the Enterprise tier offers custom style guides that enforce institutional standards, ensuring consistency in terminology. However, it’s worth noting that Grammarly doesn’t natively support the American Medical Association (AMA) style guide, making it more appropriate for drafting rather than finalizing medical documents.

Regulatory compliance is another key factor for healthcare professionals.

Regulatory Compliance Support

Grammarly complies with HIPAA Security, Privacy, and Breach Notification rules. However, handling Protected Health Information (PHI) is only allowed under the Enterprise plan, which requires a minimum of 100 seats and a signed Business Associate Agreement (BAA). To protect sensitive data, Grammarly encrypts information at rest using AES-256 and in transit via TLS 1.2 protocol. It also holds certifications like SOC 2 Type 2, ISO/IEC 27001:2022, and ISO/IEC 27701:2019.

In addition to compliance, Grammarly integrates with the tools healthcare professionals use daily.

Integration Options

Grammarly supports over 1 million apps and websites. It integrates seamlessly with Microsoft Word, Google Docs, Outlook, and Gmail through native add-ins. Browser extensions for Chrome, Firefox, Edge, and Safari enable real-time editing in web-based platforms, including research databases and Electronic Health Record (EHR) systems. For flexibility, Grammarly also offers desktop apps for Windows and Mac and mobile apps for iOS and Android, making it easy to use across various clinical and reporting software.

Jenna Kozel-King, VP of Corporate Marketing, shared that her team experienced a 50% reduction in writing and editing time after incorporating Grammarly into their workflow.

Pricing

Organizations using Grammarly have reported saving approximately $5,000 per employee annually. In 2025, Lauren Reed, a Content Strategist, noted that her organization saved $210,000 within nine months of adopting Grammarly’s tools.

Trinka prioritizes data security and compliance. It is HIPAA-compliant and offers Business Associate Agreements (BAAs). For added flexibility, it provides an offline desktop app and on-premise hosting options, ensuring data sovereignty and enabling real-time data deletion. The "Confidential Data Plan" guarantees that user data is not used for AI training.

In a notable case study, TNQ Technologies deployed Trinka’s API as part of an AI solution called "Language Central" for a leading international STM publisher. Between 2022 and 2023, this system evaluated over 20,000 articles, allowing editors to focus only on "high-intervention" pieces. This automation saved the publisher more than $500,000 annually by eliminating unnecessary copyediting tasks.

Integration Options

Trinka offers seamless integration across platforms. Its native Microsoft Word add-in provides real-time suggestions without disrupting the editing process. Browser extensions for Chrome, Firefox, and Edge enable support on web-based submission portals and research tools. For organizations, Trinka’s API can be embedded into proprietary software to automate language assessments. Additionally, the cloud-based editor accepts .doc, .docx, and .pdf uploads, allowing users to download edited documents with tracked changes for easy review.

Pricing

Trinka has earned a 4.8/5 rating on SoftwareSuggest, based on 17 user reviews.

Strengths and Weaknesses

Here’s a streamlined breakdown of the strengths and weaknesses of each tool for medical writing.

Grammarly stands out for its extensive integration capabilities. It works seamlessly with platforms like Google Docs, Word, Slack, and various CMS tools, making it a solid choice for teams juggling multiple apps. However, its style suggestions often miss the mark for medical contexts unless upgraded to GrammarlyGO Medical. On the bright side, it ensures PHI security with HIPAA-compliant measures and BAAs.

Trinka shines in regulatory and technical accuracy. For example, it can spot errors like "pregabolin" instead of "pregabalin". Its built-in AMA Manual of Style (11th Edition) checker and FDA template libraries make it a go-to for regulatory submissions. That said, its price – around $150/month – may be a hurdle, and its integration options are limited to MS Word and cloud-based editors.

At just $6/month for the Native plan, it provides cost-effective grammar and fluency improvements for day-to-day clinical writing. Its general-purpose design prioritizes clarity and readability but doesn’t include tools for regulatory compliance or medical-specific style guides.

Below is a comparison table summarizing the key differences among the tools:

This overview highlights the strengths of each tool, helping medical writers choose the one that aligns best with their specific needs and priorities.
