It's Sunday night.
The lab reports are still there.
TYay drafts feedback and scores for lab reports and problem sets, then hands everything to you. You review each score and comment, fix what it got wrong, and approve before a single comment reaches a student. The pile shrinks. Your standards don't.
Upload your rubric. Watch it grade. Fix what it gets wrong.
Drop in the rubric you already use. TYay turns it into task-by-task grading criteria and grades a sample submission in front of you. Edit the scores and feedback until it grades exactly like you do. Keep the smart assignment forever.

Mark Kernion
40 years teaching chemistry ยท Barron's chemistry author
"I don't know how I did it for all these years without TYay. For my average of 30 homeschooled students per year, I save about 5 hours per week."

Jack Kernion, EdD
40 years teaching physics
"The time savings have been incredible, and the comment quality is much more robust than I would usually do on my own."
Yes, both Kernions. TYay's first 2 users were the founder's dad and uncle: a Barron's chemistry author and an EdD physics teacher with 80 years in the classroom between them.
You stay the grader
TYay drafts. You decide. Every time.
Build the assignment
Upload your materials. TYay builds a Google Docs template with grading criteria for each question, not one blanket rubric.
Students work in their own Doc
Each student gets an editable Google Doc copy. They can self-grade against your rubric before submitting, if you turn that on.
TYay drafts feedback and scores
It evaluates free response, data tables, labeled graphs, and calculations against your criteria, then sends everything to you. Students see none of it yet.
You review, adjust, approve
Fix scores, rewrite feedback, then approve. Only then does TYay place your comments in each student's Doc, anchored right next to the work.
Built for the work you actually grade
Generic AI tools were built for essays. They guess at your titration table and skip the graph. TYay wasn't, and doesn't.
Data tables, graphs, and calculations
Evaluates the stuff generic tools skip, against your criteria for each question
Test before you assign
Run a grade, review, edit-rubric loop on sample answers until it grades like you do. Then assign it.
Anchored comments
Approved feedback lands next to the mislabeled axis or the wrong unit, in the student's own Doc. Not a portal.
Handwritten work
Reads handwritten equations and diagrams in scanned or photographed work
Student self-assessment
Optionally have students grade themselves against your rubric first
Your Drive, your files
Templates and submissions live in your own Google Drive, under your account
Your students' work stays yours
Plain answers, not legalese
Your Drive, your ownership
Student documents and templates stay under your Google account. We don't warehouse them.
Minimal permissions
TYay only asks for access to the specific files you use
Not kept, not trained on
Student work is processed for grading, then it's gone. It's never used to train AI.
FERPA, with a DPA on request
Built to operate within FERPA: teacher-controlled storage, no unauthorized sharing, and a DPA for schools and districts
Built for science and math teachers
Chemistry, biology, physics, environmental science, algebra, calculus. If you grade lab reports or problem sets, TYay drafts the grading and you keep the final say.
