CoLab today announced CoLab 4.0, the company's biggest platform step-change of 2026, bundling new collaboration and design tools, a desktop application, redesigned navigation, AI capabilities, and enterprise integrations into one major release. Together, they represent CoLab's clearest statement yet on what AI in engineering should actually look like. CoLab's customers design some of the most complex products in the world: nuclear reactors, jet engines, and medical devices.
CoLab 4.0 introduces AutoReview 2.0 and Operator AI.
AutoReview 2.0 adds 3D manufacturability checks for machining, sheet metal, injection molding.
Operator is conversational AI interface for targeted analysis and design solutions.
Out-of-the-box integrations with PTC Creo and Siemens NX.
Captures design rationale with Canvas, Notebooks, and video support.
AutoReview applies organization's standards, checklists, and lessons learned.
Adam Keating, Co-founder and CEO of CoLab, stated: "Our customers design mission-critical products, where design decisions have real world consequences. They're excited about AI, but they must adopt it in a way that preserves human judgment when the stakes are high. That's why we're building AI for engineering that prioritizes the decision making experience for human subject matter experts, while accelerating decision velocity."
AutoReview 2.0, CoLab's proactive AI peer checker, delivers faster results and broader check coverage across dimensions, tolerancing, GD&T, and BOM consistency. It also introduces 3D manufacturability checks for machining, sheet metal, and injection molding. Operator, now in early access, is CoLab's conversational AI interface where engineers can perform targeted analysis, surface design solutions from past programs, and orchestrate design and review cycles.
Jeremy Andrews, Co-founder and CTO of CoLab, stated: "AutoReview acts as a first pass check on designs, applying your organization's standards, checklists, and lessons learned. Operator works from the same knowledge base, conversationally. This represents two modes of making your organization's expertise accessible in real time. AutoReview performs deep analysis, while Operator provides coverage that's quick and wide."
CoLab 4.0 extends the platform to capture more design rationale with collaborative whiteboarding via Canvas, rich text documents via Notebooks, and video support, including timestamped commenting. Design context captured via these new tools informs AI agents working alongside engineering teams. Operator extends beyond basic chat and search by tapping into specialized agents that understand engineering designs.
CoLab 4.0 includes out-of-the-box integrations with PTC Creo and Siemens NX, letting engineers push designs from their CAD session directly into CoLab. CoLab plans to announce additional key partnerships and integrations throughout Summer and Fall 2026.
About CoLab
CoLab builds AI-powered software for mechanical engineering and hardware development teams. Its EngineeringOS platform helps engineers make better, faster design decisions by connecting people, data, and AI in one collaborative workspace—capturing expert knowledge as a natural part of day-to-day work. With AI agents built into the platform, CoLab enables teams to apply that knowledge automatically to improve design quality and accelerate product development.
