Checkd
BIM coordination that doesn't cost a fortune.
Multi-model clash detection with an AI agent built in.
BIM coordination is broken
The tools you need cost thousands per year, lock you into cloud platforms, and haven't meaningfully improved in over a decade.
Navisworks costs $2,835/yr*
Per seat. Enterprise coordination shouldn't require enterprise budgets.
Revizto locks you into the cloud
Your models, their servers, their pricing. Cloud hosting for large 3D models is expensive.
Revit's built-in check is a joke
Single-threaded, no persistence, can't share results. Fine for a demo, useless at scale.
No AI, no intelligence
Existing tools make you manually triage thousands of clashes. Clash detection hasn't evolved in a decade.

Everything you need to coordinate
Built from the ground up as a complete BIM coordination tool. Not a viewer with clash detection bolted on.
Multi-Model Loading
Load up to 50 IFC models simultaneously. Structural, MEP, architectural, all in one viewport with instant GPU rendering.
Clash Detection
AABB broad-phase collision testing across all model pairs. Create, run, and manage clash tests with element-level deduplication.
Issue Tracking
Create issues from clashes or manually. Full status workflow, linked viewpoints with camera state capture, and SQLite persistence.
Section Box
Oriented bounding box with 6 draggable faces and 3 rotation arcs. GPU shader-based per-fragment clipping for clean, real-time cuts.
Reports & Export
Generate Excel, CSV, and PDF reports with column pickers, grouping, clash screenshots, and summary statistics. Save presets for repeat reports.
BCF 2.1 Interoperability
Import and export issues in the open BCF standard. Works with Navisworks, Solibri, BIMcollab, and any BCF-compatible tool.
Category Visibility
Toggle entire IFC categories on and off. Show All / Hide All, element counts per category, and instant viewport updates.
Measurement Tool
Point-to-point distance measurement with vertex snapping and axis constraints. Multi-unit display in mm, cm, and meters.
Element Tinting
Color-code models, categories, or individual elements through the context menu. Visual clarity for complex multi-discipline coordination.
Coordination,
automated
Checkd has an AI agent built directly into the viewer. Connected via the Model Context Protocol (MCP), it has full read and write access to your models, clashes, and issues.
Ask it to triage 500 clashes, generate a coordination report, isolate all MEP vs. structural conflicts, or create issues from critical clashes, and it just does it.
Specialized tools give the AI deep access to the viewer. It can navigate, classify, search, report, and manage viewpoints. The same things you do manually, but in seconds.
From models to resolved issues
Four steps. No cloud subscription. No license keys.
Load your models
Drop in IFC files from any discipline. Checkd auto-converts them to optimized GLB geometry with full metadata extraction.
Supports IFC2x3 & IFC4Run clash tests
Select model pairs and run AABB broad-phase clash detection. Results are deduplicated to the element level. No duplicate noise.
Across all disciplinesTriage & resolve
Classify clashes as Critical, Minor, or False Positive. Create issues, capture viewpoints, and track resolution status through a full workflow.
Or let the AI do itReport & share
Generate Excel, CSV, or PDF reports with clash screenshots. Export BCF 2.1 files for interoperability with Navisworks, Solibri, and BIMcollab.
BCF 2.1 compatibleHow it stacks up
Checkd isn't trying to be Navisworks. It's trying to make Navisworks unnecessary.
