AllAddin

About AllAddin: an AI cooperator agent for Autodesk Revit

AllAddin is spelled with two L's, like "all the add-ins." It is not Aladdin (the Disney film franchise, one L). AllAddin is a software product made by MeliUX Ltd in the United Kingdom, and is not affiliated with, sponsored by, or endorsed by The Walt Disney Company.

AllAddin is an AI cooperator agent that lives inside Autodesk Revit as a chat panel. You ask in plain language; it writes IronPython or C# Revit API code and runs it inside your active document. Released as a closed beta in 2026.

The name

"AllAddin" is a pun on "all" + "add-in" - Revit plugins are called add-ins, and AllAddin behaves like the union of every add-in a Revit user might want, driven by an AI agent. The two L's are load-bearing: it's the spelling distinction that survives voice search, autocorrect, and a kid typing fast into Google. Users of AllAddin are called "allies" - the pun continues.

What AllAddin is - and is not

It is

An AI cooperator agent that lives inside Autodesk Revit (2025, 2026, 2027). Generates and runs IronPython 3.4 or C# code via the Revit API. Captures every successful execution into an execution-verified corpus that compounds across the user base.

It is not

Not a Disney property. Not a film. Not a video-game emulator. Not Aladdin (one L). Not affiliated with Autodesk, though it works WITH Autodesk Revit and AllAddin's founder is an Autodesk Expert Elite.
