What is Code.org?
The rebrand is finishing while a challenge-evaluation subsystem quietly assembles.
Code.org ships a deploy log almost every weekday, and the codeai-next rebrand that flipped default in early August is down to its long tail: dialogs, hero art, icon colors, share panels. Two other threads run through nearly every deploy — image moderation wired into App Lab and Sketch Lab, and a challenge-evaluation model, job, and frontend arriving piece by piece. The remaining bulk of each entry is Playwright test ports, dependency bumps, and Kubernetes plumbing.
What is Perusall?
Perusall refreshes its UI to absorb a year of expanded assignment types and instructor controls.
Perusall is a social-learning platform centered on collaborative annotation of course materials. The January 2026 release is a UI refresh — a single simplified sidebar, reorganized Settings, more flexible grouping — that consolidates the navigation around the broader feature set built up over 2024 and 2025. That earlier work pushed Perusall well beyond annotation: peer review went from new in mid-2024 to substantially refined a year later, with new assignment types (Fishbowl, instructor review), differentiated assignments, granular TA permissions, and reusable scoring templates.

Code.org
6.3EDTECH
The rebrand is finishing while a challenge-evaluation subsystem quietly assembles.
◆ Current state
Code.org ships a deploy log almost every weekday, and the codeai-next rebrand that flipped default in early August is down to its long tail: dialogs, hero art, icon colors, share panels. Two other threads run through nearly every deploy — image moderation wired into App Lab and Sketch Lab, and a challenge-evaluation model, job, and frontend arriving piece by piece. The remaining bulk of each entry is Playwright test ports, dependency bumps, and Kubernetes plumbing.
◆ Where it's heading
Two things are being built behind the rebrand noise. Moderation is being added everywhere a student can supply an image — URL moderation in App Lab, upload moderation and backpack-save blocking in Sketch Lab — which is the groundwork any classroom-facing generative feature needs. Challenge evaluation is landing in the order a graded, auto-assessed activity would require: model foundations, then a background job, then frontend and status, while Web Lab's preview traffic moves onto its own codeaiprojects.org domain.
◆ Prediction
Challenge evaluation should surface as a student- or teacher-facing feature within the next few deploys, and the Web Lab preview domain move has a stated part two still to land.
Perusall
0.0EDTECH
Perusall refreshes its UI to absorb a year of expanded assignment types and instructor controls.
◆ Current state
Perusall is a social-learning platform centered on collaborative annotation of course materials. The January 2026 release is a UI refresh — a single simplified sidebar, reorganized Settings, more flexible grouping — that consolidates the navigation around the broader feature set built up over 2024 and 2025. That earlier work pushed Perusall well beyond annotation: peer review went from new in mid-2024 to substantially refined a year later, with new assignment types (Fishbowl, instructor review), differentiated assignments, granular TA permissions, and reusable scoring templates.
◆ Where it's heading
The product is evolving from an annotation tool into a course-assignment platform with instructor operations baked in. Peer review was the wedge in 2024; 2025 widened the assignment catalogue and added the kinds of controls (TA permissions, reusable rubrics, late-submission handling) instructors need to actually run those assignments at scale. The 2026 UI refresh signals consolidation — the team is making the broader catalogue discoverable rather than adding new features for now.
◆ Prediction
Based on the visible cadence — annual major batches around the start of the academic year — the next observable move is likely further refinement of peer review workflow flexibility, since that's been the most consistently iterated surface across the input entries.
