Grammarly has rolled out a new document-based interface built on technology from Coda, the productivity startup it acquired last year.
The redesigned platform combines traditional writing tools with a suite of AI assistants aimed at both students and professionals.
The interface adopts a block-first design, allowing users to insert tables, columns, lists, headers, and rich text blocks to highlight or organize content. A sidebar hosts Grammarly’s AI assistant, which can summarize passages, answer questions, and provide writing suggestions in real time.
The company has also introduced specialized AI tools. “Reader Reactions” enables writers to simulate feedback from different reader personas. “Grader” offers evaluation against instructor guidelines and course materials, while “Citation Finder” helps generate references from public sources. A “Paraphraser” adjusts tone and style to suit different contexts.
To address growing concerns about academic integrity, Grammarly added agents capable of detecting plagiarism and AI-generated content. Luke Behnke, the company’s vice president of enterprise product, acknowledged that such detectors are “hit or miss” across the industry, but said Grammarly’s tool is tuned for higher accuracy. “The goal here is not enforcement,” he told TechCrunch. “It’s about giving students visibility into whether parts of their text could resemble AI output before submission.”
The new direction reflects Grammarly’s attempt to balance AI-driven assistance with safeguards against misuse. The company describes this as a “moral imperative” to prepare students to use AI responsibly while also ensuring transparency.
Grammarly has been on a rapid expansion path, acquiring the email client Superhuman last month and raising $1 billion in May from General Catalyst to fund acquisitions and strengthen sales and marketing. With its latest release, the company positions itself at the center of both AI-powered writing and AI-content detection — two forces increasingly shaping modern education and the workplace.
