AutoReview: AI that catches design issues before they slip through the cracks

AutoReview analyzes your 3D models and drawings, then adds markup and comments directly on the design, catching critical issues and helping you move faster with confidence.

AutoReview is your instant peer checker. Here’s what it can find:

AutoReview is your instant peer checker. Here’s what it can find in seconds:

Inconsistencies in Technical Data

Mismatched materials, duplicate dimensions, title block discrepancies.

Ambiguous or Incomplete Drawings

Missing views, vague notes, unclear part configurations.

Design Flaws in 3D Parts

Sharp inside corners, unsupported ribs, stress-prone geometry.

Non-Conformance to Standards

Missing tolerances, incorrect hole callouts, GD&T violations.

Conflicts with Lessons Learned

Repeat errors, common expert feedback, root causes of failures.

DFX Optimization

Thin walls, missing draft angles, complex parting lines in molded parts.

2D AutoReview: Expanded Agent Coverage

AutoReview for 2D drawings now runs a broader set of specialized agents, significantly expanding the range of technical feedback it can generate.

Previously, 2D AutoReview used a single generalist agent and primarily surfaced feedback on missing dimensions, material inconsistencies, and text typos. AutoReview now dynamically selects from a factory of specialized agents based on the content of the drawing being reviewed — covering GD&T, tolerancing, dimensioning, fasteners, view integrity, BOM consistency, and more.

Custom checklists and user input prompts work alongside the agent factory — they direct which agents are prioritized and what context they operate with. The active agents for each run are visible in the processing panel.

If you've run AutoReview on a drawing previously, you will likely see new findings on the same file. This reflects expanded coverage, not a change in the design. The agent factory will continue to expand over time.

This sounds amazing—but is it good enough for my team to use right now?

AutoReview is being used and evaluated by teams at F500 companies, with new capabilities being added regularly. Join the waitlist to stay up to date.

“AutoReview to me seems to be the big game changer for design intent.”

“Not only are you able to capture the feedback, but you're able to put that or push that forward to somebody and offer a suggestion.”

David Sellers
Senior Director of Engineering
Hoshizaki America

“It feels like we’re really on the forefront of what is coming next.”

“I can get an understanding of what my risks should be early – the first time we make it, it’s going to be better because of AutoReview.”

Scott Vanden Warsen
Design Engineer, Product Development Excellence
Molex

“We have a lot of design standards and tooling standards – and if an AI is looking at that and reviewing it for me, it’s going to be much quicker and more accurate.”

Timothy Field,
Sr. Manager Mechanical Design / CAD
BISSELL Homecare, Inc.

“We're pretty excited about [AutoReview] because it's able to track lessons learned... to harness that capital and that learning from different projects to improve future products.”

AutoReview uses specialized review agents to perform common checks

Drawing Review + Approval

Standards: GD&T accuracy, countersinks and counterbores, threading and tapping, surface finishes

Dimensional: process control and inspection, duplication and mismatch, feature control frames

Layout and setup: title block, revision tagging, orthographic and isometric views, section leaders

DFX Optimization

Molding: wall thickness, draft angles, undercuts, gate/runner placement

Machining: depth-to-diameter ratio, internal radii, complex geometry

Sheet metal: bend radii, hole placement, uniform thickness, sharp corners

See how it works

AutoReview uses your standards,checklists, and past feedback to give relevantguidance—aligned with how your team actuallyworks. AutoReview is ideal for workflows likedrawing reviews and approvals, surfacing lessonslearned and cross-functional collaboration.

Which markup is AI generated?

Why AutoReview?

Processes technical CAD data

AutoReview extracts and organizes the contents of your file before any review begins — geometry, dimensions, symbols, and metadata — so every check runs against real engineering context, not just a flat image.

Puts feedback in the design, not a document

AutoReview adds markups and comments directly to your 3D models and drawings with saved view states, so feedback is clear and actionable.

References your unique design guidelines

AutoReview references your organization's unique standards, guidelines, and review checklists. It reviews the way your team reviews, not just the way an LLM would.

Specialized agents, not a generic LLM

AutoReview uses specialized agents to find critical points of failure, producing more specific recommendations than general LLMs are capable of.

Fully integrated with CAD and PLM

With out-of-the-box integrations, you can share data directly from PLM to CoLab. AutoReview runs inside CoLab, so you can view CAD and people's comments right alongside AI-generated markups.

Enterprise-grade security, proven at scale

AutoReview runs inside CoLab’s secure infrastructure, which is already trusted by Fortune 500 manufacturers and vetted to standards like SOC 2 Type 2 and ISO 27001.

Frequently Asked Questions

How does AutoReview know what to look for—and will it work on our designs?

AutoReview analyzes your 3D models and drawings using geometry, metadata, title blocks, and part or assembly context. When you upload a design, it applies a set of built-in checks to help surface common issues such as dimensioning inconsistencies, missing details, and tolerance problems.

You can then refine how AutoReview evaluates designs by adding your own standards, guidelines, checklists, and lessons learned. Human feedback, discussion, and decisions captured during reviews provide additional context that helps guide future reviews and align results with how your team works.

Is it secure?

Yes. AutoReview runs inside CoLab’s secure infrastructure, which meets enterprise-grade standards including SOC 2 Type 2 and ISO 27001. It’s already trusted by engineering teams at Fortune 500 manufacturers. Your data stays private and is never used to train public models or shared with other customers.

Do I need to prep our data or train it before we can use it?

AutoReview can perform a set of common design checks out of the box when you upload a model or drawing, using geometry, metadata, and drawing structure to help surface issues.

You can then refine how AutoReview evaluates designs by adding your standards, guidelines, checklists, and lessons learned. Human feedback, discussions, and design decisions captured during reviews provide additional context that guides future reviews.

Will it work with our CAD or PLM system?

Yes. You can upload files directly or push them in from your existing CAD or PLM tools using CoLab’s integrations. No custom setup required.

Did you create AutoReview to replace engineers?

AutoReview isn’t about replacing engineers—it’s about scaling the knowledge and experience they already have. The goal is to free up experts from repetitive tasks so they can focus on the work that actually needs their judgment. It’s a mindset shift: instead of thinking “this tool is doing my job,” it’s “this tool helps me get through the tedious parts faster so I can focus on the real engineering work.” The teams that win will be the ones that combine smart people with smart tools, not the ones that use AI to cut headcount.

When will I get access?

AutoReview is already available to initial customer cohorts, with access continuing to roll out to additional teams each week. Reach out to us to discuss access.
