Working product
Turn supported shop drawings and illustrated PDF guides into assembly concept videos. Help customers, partners and teams see what a product is made of, and how its components come together.
The AI interprets the documentation. A structured model defines the geometry and movement. You review the result against the source.

The company behind the first product
One model.
More ways to
understand.
Latch is building toward an assembly intelligence platform: a shared model of parts, relationships and sequence that can power videos, interactive instructions and connected workflows.
Assembly Animator is the starting point. The next chapters build on the information behind the animation.

The Latch roadmap
One assembly.
A whole toolkit.
Start with a video. Make the model easier to review. Then use that shared understanding to guide the build, connect teams and investigate problems earlier.
Assembly Animator
Bring the build to life.
Turn supported PDF drawings into reviewable 3D assembly videos. This is the first working product and the starting point for everything that follows.
- PDF → component model → MP4
- Standard hardware and labeled steps
- Grouped placements and video formats
Latch Lens
See it. Check it. Refine it.
A visual review workspace for comparing the model with the drawing, resolving uncertain details and refining the sequence before sharing it.
- Source references beside the model
- Visible assumptions and review flags
- Editable steps and expert corrections
Latch Nexus
Connect every part of the picture.
Build a reusable assembly graph that connects parts, fasteners and dependencies. Expand the foundation toward native CAD and bill-of-materials inputs.
- Part and fastener relationships
- Assembly constraints and dependencies
- Native CAD and BOM-linked inputs
Latch Trail
A clear path through every build.
Turn the assembly model into interactive instructions people can follow at their own pace, from a product page to the workshop floor.
- Step-by-step interactive 3D guides
- Inspect the model at each step
- QR-code access to instructions
Latch Relay
Get assembly knowledge where it belongs.
Connect reviewed assembly information with the systems teams already use for engineering, documentation and manufacturing.
- A customer-facing API
- Documentation and engineering integrations
- Assembly data in manufacturing workflows
Latch Sentinel
Spot the problems before the build.
Explore whether the assembly model can surface sequence conflicts, hard-to-reach fasteners and buildability issues earlier in the process.
- Sequence and constraint conflicts
- Fastener and tool-access research
- Buildability checks for expert review
Assembly Animator works today. The other tool names are working names for the roadmap; their features are not available yet. The sequence shows our direction, with no promised release dates. Sentinel remains exploratory, not engineering certification.

questions.
What is Latch?
Latch is building software that understands how physical products go together. Assembly Animator is our first product: it turns supported PDF drawings and assembly context into reviewable 3D assembly concept videos.
What can Assembly Animator do today?
It interprets supported PDF drawings, creates a structured component model, plans supported placements, and renders an MP4 with labeled assembly steps. The workflow keeps assumptions and source notes available for review and supports revisions.
Which files can I use?
The current drawing workflow accepts PDFs, including shop drawings and illustrated instruction guides. Each file can contain up to 20 pages and be up to 8 MB. Native CAD formats such as STEP, IGES and DWG, plus BOM-linked ingestion, are planned rather than available today.
Is this a generative video model?
The AI supplies a structured interpretation. Geometry and motion are then rendered from that model. Parts persist across frames, and the saved plan can be checked and revised. The interpretation still needs to be compared with the source drawing.
Are the demos real product outputs?
Yes. The pump and cabinet videos were rendered by the current engine from original synthetic drawing studies and reviewed assembly plans. They show sequential placements, connection-facing cameras and the completed assembly. They are not customer projects or proof of unattended extraction from unseen PDFs.
Does it verify that a product is safe to assemble?
No. Current checks can flag modeled solid overlaps and blocked straight placement paths. They do not establish source accuracy, physical fit, tool access, torque or structural performance. Broader assembly validation is a future research direction.
Can it run without a frontend?
Yes. The local CLI prepares a PDF, checks an analysis plan and renders a verified video. An assistant or operator supplies the analysis. This route does not require the application's API key; automatic analysis in the studio uses a configured provider.
Are interactive guides and the API available?
Not yet. Interactive 3D instructions, QR delivery, a customer API and manufacturing-system integrations are on the roadmap. This website showcases the current engine and the direction of the company; it does not accept customer drawings or payments.
It starts with
“show me how.”
