Rubric Auto-Filler · Works with Canvas SpeedGrader
Your own comment on every rubric line. One click.
A Chrome extension for professors who grade with rubrics in Canvas SpeedGrader. Grade one student the way you always do, then click Set this as Default. From there, one click puts your comment on every criterion, a score on every line, and the student's first name at the top of the assignment comments. You change what that student needs, then submit it yourself.
Free while in beta. Once billing opens it's $24 a year, and you'll be asked, never charged automatically.

Both Canvas rubric types: Scale and Written Feedback
- AI inside
- No AI. It fills each rubric line with your own saved comment and score, or the top score, and it never submits a grade.
- What it can see
- It can see the SpeedGrader page that’s open. Nothing about your students comes to us or to anyone but your own Canvas.
- Where the data lives
- Your saved comments stay in your browser. The extension never contacts our site. It may ask your own Canvas for a student’s first name, who is in a group, or how the assignment is graded. Once billing opens, your license key (with a device label) is checked with Lemon Squeezy when you paste it and about once a day after.
One student, one click of Fill. Shown on a test page that copies the SpeedGrader layout, with a made-up student.
01
Set it once. Fill from then on.
The whole tool is 2 buttons on a small panel in the corner of SpeedGrader. Nothing is written to the page until you click the second one.
-
Step 1
Grade one student your way
Scores, your comment on each criterion, your standard comment in the Assignment Comments box. Then click Set this as Default. Each assignment keeps its own Default, so you set one for each new assignment.
-
Step 2
Click Fill on every student after that
With Fill with: Default (where it starts), every criterion gets the score and comment you saved, and your standard comment goes in the Assignment Comments box. With Fill with: Top Score, every criterion gets its top score and the comment boxes are left alone. Either way, the student's first name goes at the top of the assignment comments. Switch the name off if you'd rather not.
-
Step 3
Change what that student needs, and submit
Edit any line, same as you would have anyway. Then submit the way you always have. The tool never submits an assessment and never posts a grade.
Works in both kinds of Canvas rubric, Scale and Written Feedback, in the Traditional, Horizontal and Vertical views. On an assignment with no rubric, it saves and fills the grade and your assignment comment instead. Press Enter in the grade box to save the grade, the same as one you typed.
The next student, before
After 1 click
A test page that copies the SpeedGrader layout, so no real student work is on this site. The panel reads the same on your own Canvas.
02
The part of grading that isn't reading, cut by roughly a third to two-thirds.
Two timings, both from one professor's own assignments of 120 to 170 students. Which one is yours depends on where your comments come from today. They're estimates, and your own numbers will probably come out different.

about 2 mina student
- Roughly two-thirds of the rubric time
- About 4 to 7 hours back on one assignment
Timed by one professor on their own classes, on the Enhanced Rubrics feature in Canvas. The time it gives back is the rubric part, not the reading. Multiply that by however many rubric-graded assignments you set in a year.
03
It fills. You grade.
01
Never submits, never posts a grade
Submitting is the one click that's yours. The tool doesn't have a button for it.
02
Writes nothing until you click Fill
You can move between students all day, and the boxes stay exactly as Canvas left them.
03
Keeps your Default in your own browser
On your Canvas site, on the computer you're using. A different computer starts empty.
04
Sends us nothing from your grading
No account, no sign-in, no tracking and no usage reports. We never see your students, your comments or your scores. The privacy policy, in plain English.

One price, once a year.
$24
a year · paid once a year
Free while in beta. Right now it's grading real assignments, by invitation only. Once billing opens it's $24 a year, and you'll be asked, never charged automatically. Nobody holds a card for you. When billing opens the panel says so, and you decide.
Billing opens the day the Chrome Web Store listing goes public, and the Buy and Add to Chrome buttons appear here that day. A copy installed during the beta keeps filling free through December 31, 2026, the end of this semester. From January 1, 2027, Fill asks for a license key before it fills (everything else on the panel keeps working).
Want one email when billing opens?
hello@aibypeak.comPut “billing” in the subject, or let the link do it. One email when it opens, and nothing else. There's no mailing list.

Before you install.
What it needs
Google Chrome, and a Canvas site at an address ending in instructure.com, with the Enhanced Rubrics feature turned on. If your school hasn't switched to Enhanced Rubrics yet, the panel can't see the rubric, so it works as it does on an assignment with no rubric.
The panel
Sits at the bottom left of SpeedGrader. Drag it anywhere, or fold it to a title bar when you don't need it. No toolbar button and no settings page.
Your license key
Once billing opens, the receipt from your purchase carries a license key. Open any SpeedGrader page, paste the key into the box at the bottom of the panel, and press Save. Your browser remembers it from then on. The key gets checked with Lemon Squeezy, the company that sells the license, once when you paste it and about once a day after that. Nothing else from your grading leaves your browser. Manage or cancel any time at aibypeak.com/rubric-auto-filler/manage/.
If Fill ever stops
Canvas changes often, and now and then a change moves something the tool relies on. First, reload SpeedGrader, because a tab that was open when Chrome updated the extension keeps running the old copy. If Fill still stops, click Copy diagnostic and email the result to hello@aibypeak.com. It's a plain report of the page's shape, with no student names or comment text, and it's usually all we need.
Autofiller, auto-filler
Spell it either way. If a colleague said “rubric autofiller” and you searched for Canvas rubric autofill or SpeedGrader rubric comments, this is the one.
Who makes it
Peak is a small software company in Indiana. Rubric Auto-Filler grew out of one professor's grading load, and it stays small on purpose (one job, one click). Write to hello@aibypeak.com with any question about it. A person reads what you write and usually writes back within a day or two (and tells you if it'll take longer).
