Grammarly Announces the General Availability of Its Text Editor SDK

Advanced new functionality and flexible plan options from Grammarly for Developers deliver on growing global demand for comprehensive AI communication support

SAN FRANCISCO--()--Grammarly, the company powering effective communication for over 50,000 teams and over 30 million people daily, today announced the general availability of the Grammarly Text Editor SDK (software development kit). The first offering from Grammarly for Developers, the Text Editor SDK enables integration of Grammarly’s market-leading AI communication assistance into any web or desktop application. Developers are invited to begin building with the SDK for free today or contact sales to request access to paid plans with advanced functionality.

Grammarly for Developers allows builders to add real-time writing support into their applications with just a few lines of code—a process that previously required hundreds of hours building their own natural language processing models using machine learning. With newly added features and flexible plan options, the Grammarly Text Editor SDK offers the most comprehensive English-language AI communication assistance of any developer platform on the market.

“As the need for effective communication grows in more places and contexts, this release marks a major step forward in our mission to improve lives by improving communication,” said Rahul Roy-Chowdhury, Global Head of Product at Grammarly. “Opening up access to our Text Editor SDK empowers more people worldwide to communicate confidently wherever they write. Developers can bring the AI-powered communication assistance we’ve been innovating for over a decade into new digital spaces, delivering even greater impact for their end users and businesses.”

Expanding communication support with new functionality

The Grammarly Text Editor SDK has seen strong momentum and delivered deeper value to builders and users following its release in closed beta last year. Since then, the SDK received over 4,000 beta applications, checked 8+ billion words, and served 2.9+ million people. End users are realizing significant value from these implementations, giving the SDK a 4.5/5-star rating based on 34,000+ ratings in an in-product survey.

The SDK makes it easy to integrate Grammarly’s advanced writing suggestions—from leading spelling and grammar correctness to conciseness, word choice, and more—so end users feel confident in their communication. This release also includes features and functionality new to the SDK, including:

  • Tone detector: Analyzes the tone of messages to help users be confident that they come across the way they intend
  • Autocomplete: Offers complete phrases for users as they type, to make writing easier and faster
  • Analytics dashboard: Provides developers with insights and analytics into usage metrics, such as user ratings, number of words checked, and suggestion engagement, to understand and measure impact
  • Theming: Enables developers to customize the entire end-user experience, including matching the theme to their application interface

Grammarly for Developers offers an openly accessible, self-serve free plan, or developers can request access to two usage-based paid plans:

  • Free: Delivers unlimited grammar, punctuation, and spelling suggestions
  • Starter: Everything in Free plus the option to remove user prompts encouraging registration with their own Grammarly account
  • Plus: Everything in Starter plus Grammarly’s advanced features, including autocomplete, clarity-focused rewrites, and feedback on tone, engaging word choice, and inclusive language

Delivering business impact across use cases

Developers are improving outcomes across a range of use cases with the Text Editor SDK, from streamlining internal content creation to enhancing customer-facing communication. Applications especially seeing impact include online marketplaces with a high volume of user-generated content, internal content management systems (CMS) and document systems, customer support and communication platforms, AI copywriting tools, and email, chat, and social media management platforms.

Companies like G2, Front, GoFundMe, Upwork, and Hootsuite are seeing positive business results after integrating the SDK into their applications, from increased content quality to higher output, productivity, and time and cost savings.

G2, the world’s largest and most trusted software marketplace, has enhanced the quality of user reviews on its platform with the SDK. “With over 1.8 million peer reviews in our marketplace, we recognize the importance of the quality of those reviews to be a trusted resource for buyers who rely on authentic feedback from their peers,” said Rachel Bentley, Senior Director of Product Management at G2. “Many factors impact review quality, from length, relevance, and reviewer credibility to the way it’s written—and this is where Grammarly’s SDK plays a key role. Following a quick integration, our customers are seeing immediate improvement in the quality of reviews—with 50% of approved reviews per month including at least one Grammarly suggestion.”

Front, a leading customer communication hub with over 8,000 customers, integrated the SDK into its composer to support customers with more accurate and efficient communication. “Front’s mission is to enable better relationships at scale. We help businesses communicate efficiently and effectively with customers, especially in high-stakes communications where custom replies are the norm and being well-formatted is a requirement,” said Nate Abbott, Head of Product at Front. “Integrating Grammarly and its Text Editor SDK directly into Front provides Front users with enhanced behind-the-scenes automation that allows them to write the highest quality communication as fast as possible.”

GoFundMe, the most trusted online fundraising platform that supports individuals and their communities, is leveraging the Grammarly Text Editor SDK to empower fundraiser organizers to tell their stories with greater ease. “Creating a GoFundMe fundraiser can be deeply personal. We believe that help is powerful, but recognize that asking for it can be hard,” said Lili Strasser, Partnerships Manager at GoFundMe. “By integrating Grammarly’s suggestions, we’re giving our users additional support and confidence to write their fundraisers in the most compelling way and raise funds for causes they care about.”
