v0.41July 2, 2026· A more powerful grading model
Improved
Upgraded models on Student Pro and Student Max
The models behind Student Pro and Student Max moved up a generation — Address and Oration now reason more deeply on every grade, for sharper predictions and feedback that reads even more like your teacher. Same plans, same price, and the Free plan keeps the same fast model it's always had.
v0.40June 27, 2026· Refer friends, group drafts, faster pages
New
Refer a friend, get a free upload
Grab your personal invite link from the refer-a-friend popup or your profile page — every friend who signs up earns you a bonus upload on top of your weekly plan, saved until you use it. Invited friends can join straight from your link without needing a beta code.
New
See your drafts grouped into one essay
When you submit several drafts of the same essay, we now spot them and offer to group them into one card with a version history, so you can follow a piece from your first draft to your latest at a glance. Each draft keeps its own grade and feedback, nothing is merged or deleted, and you can ungroup anytime. We also tidied up the revision timeline so it reads the same on every draft, and the score changes between drafts now line up with your rubric breakdown.
Improved
Snappier page-to-page navigation
Moving between your dashboard, growth, accuracy, and other pages now feels near-instant — a tap shows a clean loading preview right away instead of leaving the old page stuck while the next one loads.

v0.35June 19, 2026· Fairer growth tracking and clearer plans
