Tell Revit
what to build.
Describe the outcome in plain language. NexusAI inspects your model, writes and runs the Python, verifies the result, and corrects itself until the job is done.
- Model inspected
- Revit API searched
- Python executed
- Geometry verified
Frontier models from the leading providers. Pick the one that fits the task and budget.
State what you need, not how to code it.
Describe the outcome
One ribbon button opens NexusAI. Your version, views, levels and worksets flow in on their own.
It plans
The agent inspects your model and searches the Revit API for the right signatures, streaming its reasoning as it goes.
It executes
Python runs directly in your open model, inside scoped transactions and behind safety validation.
It verifies and iterates
NexusAI renders an annotated image of the change, measures it in Revit, and retries with targeted edits until the task is complete.
Finished Revit work, not advice.
Full agentic loop
One request triggers the whole workflow: inspect, search, execute, verify, retry. Every phase streams live so you always see what it is doing.
Revit 2021–2027, one installer
Seven years of Revit from a single install. API calls adapt to the version you have open.
Grounded in the real Revit API
Semantic search over the Revit SDK finds the correct signatures, parameters and overloads before any code runs.
Live Revit context
Knows your active document, version, units, phases, views, levels and worksets, so every automation is tailored to the open model.
Bring your project data
Drive automations from Excel, PDFs, Word documents, web APIs and images while the work is running.
Safe by default
Scripts are validated before they run and execute in scoped transactions. Stop a run at any time and your model stays protected.
It looks at what it built.
After a geometric change, NexusAI rebuilds the affected elements in 3D and renders an annotated image of the result. It judges shape and placement from the picture, and size, gaps and elevations from exact measurements taken in Revit.
- Built from the elements themselves, so it never depends on your views or view templates.
- Clashes, duplicates, near misses and open wall ends are measured and marked, with a close-up when a problem is small.
- Explore the same geometry yourself in the Visualizer: orbit, isolate, x-ray and drag a section cut.
A two-story house from a single prompt.
Watch reasoning, API search, script execution and verification stream in as NexusAI builds the model end to end.
Your model stays on your machine.
Execution happens in the Revit session on your workstation. The add-in opens a single outbound connection, so IT has nothing to expose.

Simple, transparent pricing.
Every plan includes the full agentic loop, every model, and Revit 2021–2027. Individual tiers differ only in monthly AI usage.
Individual
Every Individual plan starts with a 14-day free trial. Add a card at sign-up; nothing is charged until the trial ends, and you can cancel any time before then. The trial includes a starter AI allowance and a limited model selection. Every model unlocks when your plan starts. One trial per person, card, and computer.
