Install the NexusAI Revit add-in and run full agentic automation — inspect your model, search the Revit API, execute Python, review enriched execution results, and iterate until the job is done. One installer for Revit 2021 through 2027.
A valid NexusAI subscription is required to activate the add-in. Individual plans are set up directly inside the Revit add-in. Enterprise plans are created at the NexusAI web portal, then accessed through the add-in.
Individual tiers ($20–$100/month) are set up in Revit. Enterprise uses the web portal.

Choose your tier in the Revit add-in when you sign up. No web portal required.
Create your company account on the web, then deploy the add-in to your team.

Double-click the downloaded file. If Windows SmartScreen appears, click More info → Run anyway. The installer handles all dependencies automatically.
Open Revit and find the NexusAI ribbon tab. Click the NexusAI button to open the AI assistant.
Individual plans (from $20/month): Follow the Revit add-in prompts to choose your tier, create your account, and activate your subscription.
Enterprise plan: Create your company account and purchase seats at app.getnexusai.net first. Once your enterprise account is set up, open the add-in in Revit and sign in with your enterprise credentials.
Autonomous multi-step workflow: collect model data, search the Revit API, execute Python automation, return enriched execution results, evaluate outcomes, and retry with code edits until the task succeeds.
Single installer supports seven years of Revit. NexusAI adapts API calls to your installed version automatically — from legacy 2021 projects to the latest 2027 release.
Semantic SDK search built into the agentic toolchain finds correct method signatures, parameters, and overloads before complex automations run.
After model-changing scripts, NexusAI returns structured change reports — element categories, types, levels, hosts, worksets, and MEP connectivity — so the agentic loop can verify outcomes from data and iterate with targeted code edits when needed.
Watch AI reasoning, API lookups, script execution, and enriched result evaluation stream in real time through a transparent workflow panel.
Claude Opus 4.8, Claude Sonnet 4.6, GPT-5.5, GPT-5.4, GPT-5.3 Codex, Gemini 3.1 Pro, and six more — each with native tool use across the full agentic loop.
Python runs directly in Revit with scoped transactions, up to 5-minute tool timeouts for complex tasks, and cooperative stop at any time.
Process Excel, PDFs, Word documents, web APIs, and images inside the agentic loop for data-driven automations.
Silent background update checks. When a new version is ready, an “Update Available” button appears in the Revit ribbon — close Revit and it installs itself.
New Python packages delivered alongside add-in updates — works on physical machines, persistent VMs, and non-persistent VDI environments.
Download NexusAI and let the agentic loop inspect, execute, verify, and iterate inside Revit 2021–2027.
