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.
What is TAO Testing?
TAO Testing ships rapid v56.x patches driven by NYSED client work, security remediation, and localization fixes.
TAO Testing is in a high-frequency patch release cycle across v56.12.x and v56.13.x, shipping multiple releases per week. The content is predominantly maintenance: feature flag cleanup (removing FEATURE_FLAG_RESOURCE_COMMENTS_ENABLED per NYSED specifications), critical security vulnerability remediation in the build toolchain, Crowdin localization sync corrections, and minor UI alignment fixes. The one functional addition is TaskOrchestrator email notification support in v56.13.0, indicating active development of asynchronous assessment workflow automation. NYSED-prefixed tickets throughout the releases signal active delivery work for the New York State Education Department.

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.
TAO Testing
5.0EDTECH
TAO Testing ships rapid v56.x patches driven by NYSED client work, security remediation, and localization fixes.
◆ Current state
TAO Testing is in a high-frequency patch release cycle across v56.12.x and v56.13.x, shipping multiple releases per week. The content is predominantly maintenance: feature flag cleanup (removing FEATURE_FLAG_RESOURCE_COMMENTS_ENABLED per NYSED specifications), critical security vulnerability remediation in the build toolchain, Crowdin localization sync corrections, and minor UI alignment fixes. The one functional addition is TaskOrchestrator email notification support in v56.13.0, indicating active development of asynchronous assessment workflow automation. NYSED-prefixed tickets throughout the releases signal active delivery work for the New York State Education Department.
◆ Where it's heading
The NYSED-prefixed tickets driving most releases indicate TAO is in a client-specific delivery phase where a large, high-stakes contract is setting the near-term agenda. Feature flag removals (FEATURE_FLAG_RESOURCE_COMMENTS_ENABLED going from add to remove across the v56.9–v56.13 range) suggest a feature has shipped and is being stabilized. The TaskOrchestrator email notification work hints at a broader asynchronous assessment orchestration capability being built out incrementally.
◆ Prediction
The NYSED delivery work will continue to drive short-term releases. TaskOrchestrator email notifications are likely the first visible piece of a larger orchestration layer — expect follow-on releases adding more notification types or triggering conditions as the capability matures.
