01
Upload your material
Start with the materials you already use.
PDFs, worksheets, prompts you have used for years. Drop them in and connect a rubric — no new template to learn, no format to convert.
Assisted grading
Grading should feel human again.
AI drafts the work. Teachers shape the outcome.
MateFlow helps teachers reduce repetitive grading work while keeping human judgment at the center of every decision.
The workflow
One loop. Four steps. Teacher in the middle.
Each step has a clean handoff, and the teacher is the gate before anything reaches a student. Nothing auto-publishes.
02
AI creates the first draft
Save hours on repetitive work.
The first pass is done — scores, justifications, rubric matches — before you sit down to review. The model writes the boring sentences so you do not have to.
03
Teachers stay in control
AI assists. Teachers decide. Every final decision belongs to the teacher.
Edit any score, rewrite any comment, override the model. Nothing leaves your hands without your approval — and nothing is ever sent automatically.
04
Feedback becomes communication
Better feedback creates better learning.
What goes back to students is yours — phrased the way you would phrase it, framed the way you would frame it. The rubric travels with the comment.
What makes it different
Not another auto grader.
Most AI grading tools want to replace the assessment. MateFlow keeps the teacher between the model and the student — every time, by default.

Teacher review system
Built so the teacher is always the editor.
Six pieces of the review surface are already shipping. Each one exists to keep the AI draft from becoming the final word.
Draft label system
Every AI output is marked as a draft until a teacher signs it. No silent promotion to final.
Confidence score
The model flags its own uncertainty per criterion, so review time goes where it matters.
Item-by-item review
Walk the rubric one criterion at a time, with the source passage cited beside the score.
Manual override
Change a score, rewrite a sentence, replace the draft entirely. The override is the record.
Hold / regrade support
Send a submission back through the loop with new context, or pause it for a private conversation first.
Audit trail
Every edit, override, and approval is timestamped and attributable. The grade is yours, on the record.
Worksheet support
The page is the workspace.
Worksheets do not stop at a score. Drawing, highlighting, and typed annotation all travel with the feedback the student sees.
01 · PDF upload
Drop a scanned worksheet, a typed handout, or a stack of submissions. Bulk upload is supported.
02 · Page conversion
Pages are rendered for review and OCR runs in the background — text and layout, not just an image.
03 · Annotation workspace
Draw, highlight, and type directly on the page. The stylus-first surface is built for review at speed.
04 · Teacher review
Approve, edit, or send back. The annotated page travels with the rubric into the student feedback.
Privacy & security
Student work stays student work.
- No AI training on student submissions

In active beta
Some features and UI may change before public launch.
Technology should support teachers, not replace them. More time for students. Less time on repetitive work.
