Grammarly has rolled out a fresh, document-based interface built on Coda, the productivity startup it acquired last year. This upgrade introduces an AI assistant alongside new tools for students and professionals, such as an AI grader, proofreader, and citation finder.
The interface uses a block-first design. You can add tables, columns, lists, headers, separators, or rich text blocks to highlight key points or insert tips and alerts. On the side, a new AI assistant is ready to summarize text, answer questions, and suggest edits in real time.

The update also brings several AI tools. Reader Reactions lets you select a reader persona and get tailored feedback. The grader evaluates work using the instructor’s guidelines and public course material. Citation Finder locates and generates citations from open sources. Paraphraser adjusts tone to match your style.
Grammarly has also added AI agents. These can check for plagiarism and flag AI-generated content. Luke Behnke, Grammarly’s VP of enterprise product, said the company has tuned its detector to be among the most accurate available. He stressed it’s meant to give students visibility into their work, not enforce rules. Teachers who want enforcement can use the authorship tool.

Together, these features aim to help students and professionals both use AI and understand its limits. Grammarly says it has a “moral imperative” to prepare users for the modern workplace by teaching responsible AI use.
Looking ahead, Grammarly plans to integrate more AI agents into its ecosystem. Its recent acquisition of Superhuman signals that direction. In May, the company also raised $1 billion from General Catalyst to drive acquisitions, sales, and marketing growth.
