Computer Use
You're Spending a Full Workday Every Week Just on Grading. That Stops Now.

A 2025 Learnosity survey of 258 U.S. teachers found they spend an average of 9.9 hours per week on grading alone. That's more than a full extra workday, every single week, on top of actually teaching. And 62% of those teachers say grading is a major source of work-related stress. Nearly a third have considered leaving the profession entirely because of it. Think about that. Teachers, people who chose this career because they love helping students learn, are quitting because they can't escape the pile of papers on their desk. Meanwhile, the existing tools are a joke. Auto-graders only handle multiple choice. Rubric tools still require you to open every submission by hand. Dedicated AI graders are locked to one LMS and fall apart the moment your workflow doesn't match their template. None of them actually use a computer the way a human would. Coasty does. It's a computer use AI agent that sees your screen, navigates your actual tools, and handles the full grading workflow from opening submissions to entering scores to posting feedback, just like you would, only without the burnout.
How Coasty's Computer Use Agent Handles Education Workflows
Most 'automation' tools in education are glorified macros. They work if your assignments are multiple choice, your LMS is the one they support, and your rubric fits their rigid template. The second anything is different, you're back to doing it by hand. Coasty works differently because it's a true computer use agent. It literally sees your screen and operates your software the same way you do. Open Canvas, Blackboard, Google Classroom, or any other platform and Coasty navigates it visually, no API integration required, no IT department sign-off, no six-month implementation project. It opens each student submission, reads the content against your rubric, assigns scores, writes individualized feedback based on what that specific student actually wrote, enters the grade into your gradebook, and moves to the next one. For a class of 30 students with a written assignment, that's a task that takes a teacher 3 to 5 hours manually. Coasty handles it in the background while you do literally anything else. According to Gallup's 2025 research, teachers who use AI tools weekly save an average of 5.9 hours per week, which adds up to six full weeks per school year. Coasty pushes that ceiling higher because it handles the multi-step, cross-platform tasks that simpler AI tools can't touch. It's not answering a chat prompt. It's doing the actual computer work.
Why This Beats Every Other Option
- ●Works on any LMS without integration: Canvas, Blackboard, Moodle, Google Classroom, Schoology. If you can open it in a browser, Coasty's computer use agent can work in it. No API keys, no IT tickets, no waiting.
- ●Grades essays and open-ended responses, not just multiple choice. Coasty reads actual student writing, applies your rubric criteria, and writes feedback that references what the student said. Not a template. Not a score out of 10 with no explanation.
- ●Handles the full workflow end to end. Other tools grade but don't post. Or post but don't write feedback. Or write feedback but can't navigate your specific gradebook setup. Coasty does the whole thing, start to finish, because it operates your computer like a human would.
- ●82% on OSWorld, the gold-standard benchmark for computer use AI agents. That's not a marketing number. It's a verified score on a 369-task benchmark that tests real-world computer navigation. It means Coasty actually completes the tasks it starts.
Teachers spend 9.9 hours per week grading. That's 396 hours per school year. At the average U.S. teacher salary, that's roughly $9,000 worth of your time spent on a task a computer use agent can handle. Every year.
Real Results When You Automate This
When teachers hand grading off to a computer use agent, a few things happen fast. First, turnaround time collapses. Students who used to wait a week for feedback on an essay get it the next morning. Faster feedback is better feedback, and research consistently shows it improves learning outcomes. Second, consistency improves. Human graders get tired. The 28th paper in a stack gets less careful attention than the 3rd. A computer use agent applies your rubric identically to every submission, every time, at 2am as well as 2pm. Third, teachers get their evenings back. The Gallup data is clear: weekly AI users save nearly six hours per week. That's not a rounding error. That's the difference between a teacher who stays in the profession and one who burns out and leaves. One high school teacher using a computer use agent for a 120-student load reported cutting her weekly grading time from 12 hours to under 2. Another professor handling three sections of a writing-intensive course said he went from dreading assignment due dates to treating them as non-events. The work just gets done.
You didn't become a teacher to spend 400 hours a year entering scores into a gradebook. Coasty's computer use agent handles the grading stack so you can focus on the part that actually requires a human. No integration headaches, no LMS restrictions, no credit card required to start.
