Skip Assignly if you need deep LMS functionality, API access, or a mobile app for grading on the go — or if your grading scenarios demand nuanced human judgment in creative writing.
Free plan caps at 10 graded assignments per month, so you'll hit the ceiling quickly if you grade in bulk — upgrading to Pro at $12/mo is almost inevitable.
Assignly's $12/mo Pro is cheaper than most dedicated grading tools (e.g., Gradescope) and much cheaper than hiring help. The free tier is a genuine entry point for solo teachers, but the 10-assignment cap quickly pushes active teachers to pay.

About Assignly
Assignly is an AI-powered platform built to lighten the administrative load on K-12 teachers. Its core capability is automated grading, combined with AI-generated lesson plans aligned to curriculum standards and analytics that track student progress. Teachers can upload their own assignments or use built-in templates, and the AI handles scoring, feedback, and data tracking in one place. The platform serves individual teachers, grade-level teams, and whole schools, supporting multiple subjects and grade levels, so it flexes to different classroom workflows. Beyond saving time on grading, Assignly turns raw scores into actionable insights. It identifies learning gaps, suggests interventions, and monitors progress over time—so teachers see not just grades but what to do next. For collaboration, it syncs rosters and assignments automatically with Google Classroom and Canvas, cutting manual setup. Privacy is a clear priority: FERPA compliance and data encryption are baked in, which matters when student work is processed by AI. Assignly uses a freemium model, with a free tier allowing a limited number of graded assignments per month. Upgrading to the Pro tier unlocks unlimited grading and advanced analytics, while school-wide pricing is available through sales. The platform is designed for low friction—teachers can start grading and planning without a steep learning curve, making it a practical alternative to more complex ed-tech systems. For K-12 teachers who want to reclaim hours lost to grading and lesson prep, Assignly delivers a straightforward, secure solution. Its simplicity is its strength, though it may lack the depth needed for highly specialized grading scenarios.
Behind the Verdict
Assignly shines as a pragmatic tool for K-12 educators who want to reclaim hours spent on grading and lesson prep. Its AI grading is fast, and the standards-aligned lesson generator is genuinely useful for new teachers and veteran alike. The free tier is a smart entry point, letting you test the waters before committing to the $12/mo Pro plan. For a single teacher, that Pro price is a bargain compared to hiring a teaching assistant. Where it fits: classroom teachers in grades 1-12 who primarily assign structured essays and short answers. Grade-level teams can co-plan and share assignments, and schools can deploy it broadly to lighten workload. The Google Classroom and Canvas sync eliminates manual roster and assignment setup, which is a huge timesaver. Where it doesn't: if you teach creative writing and rely on nuanced, human feedback, Assignly's AI grading will feel superficial. Similarly, if you need deep LMS functionality, this isn't a replacement. There's no API, so power users can't script workflows. And without a mobile app, you're tied to your laptop during grading marathons. Privacy is a plus: FERPA compliance and encryption are explicit, which matters when student work goes through AI. But note the free tier caps at 10 assignments a month, so heavy users must upgrade quickly. Overall, Assignly is a practical, no-frills tool that delivers on its promise of speed and simplicity. It won't replace a human grader's judgment, but for the bulk of K-12 writing assignments, it's a time-saver worth the subscription.
