A mAgIc agent/operator inside Revit.
Ask in plain language. AllAddin runs the Revit API for you - creating sheets, fixing views, chasing down rogue parameters, running quantity takeoffs. No macros, no scripting, no tab-switching to Claude or Codex.
- Talks to Revit directly. Native add-in, not a bolted-on MCP. Full access to the API and UI, executes against the live model.
- Learns tricks. Captures what you do once so the next user doesn't have to work it out again.
- Build your own tools. Turn any workflow into a reusable add-in - describe what it should do and AllAddin writes, tests, and installs it.
- Private and secure by default. Your model information never leaves your machine. Only the prompt and a structured abstraction go to the AI.
What it actually does
The concrete stuff. No jargon, no demo-ware, no screenshots of a model you'll never have.
Chat panel, inside Revit
A docked pane in every Revit session. Type what you want. Watch the model change. Never alt-tab to a browser again.
Dual-runtime execution
Writes Python (IronPython) or C# (Roslyn) from the same conversation, for the Revit version you're running. .NET 8 for Revit 2025–2026, .NET 10 for 2027+.
Error recovery built in
If the generated code fails, AllAddin reads the stack trace, diagnoses the issue, and retries. You see the result, not the attempts.
Captured tricks
Every solution that works gets stored. The corpus grows with every session, shared across users, version-aware. The longer it runs the sharper it gets.
Tool creator
Describe a reusable tool in one sentence. AllAddin writes it, asks you to confirm, then drops a ribbon button in your My Tools panel.
Multi-step workflows
Chain operations into reusable flows. "Tag all the doors, set fire ratings, publish the sheet" becomes one command.
Attachments & context
Drop a PDF of the brief, a specification image, or a vendor datasheet into the chat. The model reads them alongside your prompt.
Session history & export
Every conversation saved. Revisit from the sidebar. Export any session as a standalone HTML file for debugging or sharing.
Tool creator: describe it, get a ribbon button
The killer demo. One sentence becomes a real tool you can click again tomorrow.
Describe
"Create a tool that makes a cropped 3D view around my selected elements."
Confirm
AllAddin shows the plan and the generated code. You approve before anything ships.
Reload & run
A new button appears in your My Tools ribbon panel. Click it next time you need that view.
