Why ClassLens?
Grade 150 papers in the time it used to take to grade 40, and walk into class knowing exactly what your students need.
Grading Has Always Been Outsourced
Teaching assistants. Peer grading. Scantrons in 1972. Bubble sheets. Google Forms quizzes. Teachers have always looked for ways to handle the volume, because 150 papers a week was never sustainable by hand.
ClassLens is the natural next step in that progression. The difference is that now the tool gives feedback, not just a score. Every student gets personalized comments tied to your rubric, and you stay in control of what reaches them.
The same workflow scales to district adoption, where every teacher gets the same toolset across departments and grade levels.
What ClassLens Does for You
Less time grading. More time teaching. Better data on what your students actually need.

150 students at 10 minutes each is 25 hours. With ClassLens, review AI-drafted grades in 2-3 minutes each for roughly 7 hours total. That is 18 hours back for lesson planning and one-on-one support.
After every grading job, see class-wide strengths and growth areas at a glance. Walk into class knowing exactly where to focus your instruction.
Paper 1 gets the same attention as paper 150. No fatigue drift. No grading inconsistency. Every submission evaluated against the same rubric with the same rigor.
Every student gets detailed comments addressing them by name, referencing their actual work, connected to rubric criteria. Not generic boilerplate.
Every grade is saved as a draft. Nothing reaches students without teacher approval. The AI is the assistant; the teacher is the authority.
No prompt writing, no copy-paste workarounds, no technical configuration. A simple interface built for teachers, not engineers. If you can use Google Classroom, you can use ClassLens.
Not for Everything
ClassLens grades the file types teachers actually assign — typed essays, handwritten work (photographed or scanned), lab writeups with data tables and diagrams, CAD drawings exported as images, student-drawn graphs and sketches, PDFs, slides, spreadsheets, and multi-file submissions.
It does not replace hands-on assessment. Shop class projects, music performances, PE skill evaluations, lab technique observations, audio recordings, and video submissions. Those require human presence or capabilities that are not ready yet.
ClassLens handles the stack of grading on your desk so you have more time and energy for exactly those moments.
