What is Code.org?
Code.org is building adaptive AI-powered learning infrastructure at a daily release cadence.
Code.org ships daily releases across its Lab2 platform, steadily expanding an AI Lab with trainable ML models (decision trees, KNN, configurable hyperparameters), an AI Tutor, and a Unified Backpack for cross-tool save and share. A parallel track is adding quiz and assessment authoring to levelbuilder. The platform also removed its Skill model and Skills dashboard this week, signaling a deliberate simplification of the teacher-facing assessment surface.
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
8.8EDTECH
Code.org is building adaptive AI-powered learning infrastructure at a daily release cadence.
◆ Current state
Code.org ships daily releases across its Lab2 platform, steadily expanding an AI Lab with trainable ML models (decision trees, KNN, configurable hyperparameters), an AI Tutor, and a Unified Backpack for cross-tool save and share. A parallel track is adding quiz and assessment authoring to levelbuilder. The platform also removed its Skill model and Skills dashboard this week, signaling a deliberate simplification of the teacher-facing assessment surface.
◆ Where it's heading
The converging threads — AI Lab's growing trainer suite, adaptive level scaffolding, and an AI Tutor reading structured quiz responses — point toward a platform where student-built models influence which content gets served next. Sprite Lab is being ported into Lab2 with full parity (sound, image, scene UI), and the Unified Backpack is becoming the persistence layer across all labs. Code.org is building the delivery infrastructure for adaptive, AI-native K-12 education.
◆ Prediction
The adaptive level scaffolding will be wired to student performance data within the next few releases, likely connecting quiz attempt outcomes to level selection logic. The AI Tutor's schema-response architecture suggests it will serve as the interface layer between ML model outputs and student-facing content adjustments.
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.
