Grammarly has unveiled a redesigned document-based interface powered by Coda, the productivity startup it acquired last year, in a move that significantly expands its AI-driven offerings for students and professionals.
The new interface introduces a block-first design that allows users to insert tables, columns, lists, headers, and separators while also supporting rich text blocks for highlights, tips, and alerts. A sidebar now hosts an AI assistant capable of summarizing text, answering questions, and providing writing suggestions.
Beyond the revamped workspace, Grammarly has added several specialized AI tools. These include “Reader Reactions,” which simulates different audience personas to provide tailored feedback; “Grader,” which evaluates writing based on an instructor’s guidelines and publicly available course materials; “Citation Finder,” which helps generate proper references; and “Paraphraser,” which modifies tone and style according to user preferences.
The platform also introduces AI agents designed to detect plagiarism and AI-generated content. While acknowledging the limitations of current AI detection technology, Luke Behnke, Grammarly’s vice president of enterprise product, told TechCrunch the company has fine-tuned its system to be among the most accurate in the market. He added that the tool is not intended for enforcement but rather to give students insights into what portions of their text may appear AI-generated before submission.
“This is about providing a window to students into what could be AI-generated text in their writing before they submit,” Behnke explained, emphasizing that enforcement remains the role of educators using Grammarly’s authorship verification tools.
With this release, Grammarly finds itself balancing two seemingly opposing missions: helping students use AI to improve their writing while also offering safeguards to detect overreliance on automated tools. The company says it sees this as part of a “moral imperative” to prepare students for a future where AI literacy will be essential in the workplace.
The expansion comes at a time of aggressive growth for Grammarly. In May, the company raised $1 billion from General Catalyst to accelerate acquisitions and strengthen its sales and marketing push. Just last month, it also announced the acquisition of email client Superhuman, signaling its broader ambition to integrate AI agents across its suite of productivity tools.
