Grammarly's new AI agents can predict your paper's grade

Grammarly is turning its attention to the ultimate student anxiety: guessing what grade a professor will hand out.

The writing assistant company just announced the launch of nine specialized AI agents inside docs, its AI-native writing surface. The new lineup is rolling out immediately to Grammarly Free and Pro users at no extra cost, with Enterprise and Education tiers getting access later this year.

An AI that grades your paper before your professor does

The headline feature here is an AI grader agent. Students can upload course details and publicly available info about their instructor, and the agent will return customized writing advice alongside a predicted grade for the paper in its current form.

Jenny Maxwell, Head of Grammarly for Education, framed the move as teaching students how to collaborate with AI rather than letting it bypass actual learning.

Other student-focused tools include a reader reactions agent to anticipate audience questions, a proofreader for inline tweaks, and a paraphrase agent to shift style and tone. A citation finder automatically pulls in properly formatted sources to back up claims, while an expert review agent provides subject-specific feedback.

Playing both sides of the classroom

While seven of the agents cater directly to writers, Grammarly is also pitching tools to educators tasked with grading them.

The company rolled out a plagiarism checker agent that scans databases, academic papers, and published web content, alongside an AI detector agent that scores how likely a piece was generated by machine. Both detection agents are reserved for Grammarly Pro users at launch.

Why it matters

For students, getting an instant read on where an essay falls before the deadline is undeniably useful. If you regularly stress over rubric requirements or struggle to hunt down valid citations, this is worth testing out inside Grammarly docs right away.

Yet Grammarly is setting up an interesting tension by trying to serve both students and educators at the same time. On one screen, an agent helps craft arguments, rewires tone, and mimics teacher preferences; on the other screen, an agent scans for artificial text and flags similarities. It is essentially arming students with better generation tools while selling teachers the radar to catch them.

We think the predicted grade feature will be a massive hit with anxious students, but leaning on an instructor's public persona to forecast grades feels a bit gimmicky. Moreover, commercial AI detectors are notoriously prone to false positives. Leaning into automated grading and detection risks turning essay writing into an algorithmic arms race between pupils and professors.
