Frequently asked questions

Yes. AllAddin generates per-room data sheets that export as Excel (xlsx, multi-sheet workbook with one tab per floor), PDF (one A3 landscape page per room), or Word (docx, editable for redline review). Send the file to your client, QS, or specifier. They edit in their preferred tool. When they send the edited xlsx back, the Import xlsx button on the Room Data Sheet widget in Dashboards (an optional module) reads it and writes the changes back onto the Room shared parameters automatically. The whole round-trip works without your reviewer ever opening Revit.

Yes. The Dashboards Room Data Sheet template exports a multi-sheet workbook (Cover sheet, master schedule, per-floor tabs) that mirrors the typical AEC Room Data Sheet format. Edited values come back into the model via the Import xlsx button on the same Room Data Sheet widget, in one undoable Transaction. Dashboards is an optional module. The exporter is openpyxl-based and runs server-side; the dashboard triggers a browser download.

AllAddin supports Autodesk Revit 2025, 2026, and 2027. The same installer covers all three versions; AllAddin auto-detects your installed Revit and registers itself accordingly.

The standard AllAddin installer covers Revit 2025, 2026 and 2027. Revit 2024 is not included.

Autodesk's Revit AI Assistant ships only with Revit 2027. AllAddin runs on Revit 2025, 2026, and 2027, is independent of Autodesk's account / Autodesk Platform Services (formerly Forge) plumbing, and exposes both an IronPython 3.4 and a C# / Roslyn execution path. AllAddin is made by MeliUX Ltd in the UK.

Dynamo is a visual programming tool; pyRevit is a Python scripting host. Both require you to write or wire up code yourself. AllAddin generates the code on demand from plain language, runs it inside a Revit transaction, and reports what changed. You don't need to know the Revit API to use it.

Copilot and Cursor are general-purpose code assistants that live in your editor. AllAddin is purpose-built for the Revit API: it knows the differences between Revit versions, lives inside Revit as a chat panel, and runs the code it writes against your active document - not in a separate IDE.

Both. AllAddin can generate IronPython 3.4 (run by AllAddin's own bundled engine) or C# (compiled with Roslyn at runtime). You pick the language per request, or let the agent choose based on the task.

Your .rvt model never leaves your machine. AllAddin sends the chat text plus a small extracted context (active view, selection summary, version) to the backend, which proxies to Anthropic's Claude API. Generated code returns to your Revit session and runs locally. If it fails or prints output, the code, its errors and that output may go back through the backend so AllAddin can fix the code or summarise the result. The backend does not keep these AI requests. Improvement sharing, on by default with an opt-out, keeps the prompt, the generated code and the outcome. See https://alladdin.dev/privacy.

A package manager for AllAddin. Curated tools (sheet builders, material lookups, parametric helpers, schedulers) install with one click and become first-class commands inside the chat panel. Browse the catalog at https://alladdin.dev/market.

Yes. Each extension is an .allax bundle - a zip with manifest, code, and assets. Marketplace copies are signed, and AllAddin checks the signature when it installs from the marketplace. You can build one privately for your team, or publish it to the public marketplace through the submission queue at https://alladdin.dev/market/publish.

AllAddin is in beta during 2026. Beta access is free for evaluation; production pricing will be announced before general availability.

AllAddin is in closed beta. Request access via the signup form on https://alladdin.dev/ - once approved, you'll receive an installer link by email and a sign-in token. Run the MSI on a Windows machine that has Revit 2025, 2026, or 2027 installed. The installer asks for your token, lets you choose which of the detected Revit versions to install for, and lists the optional modules for you to tick.

Yes. AllAddin runs in the active Revit document the same way any add-in does. It respects Revit's worksharing transactions. BIM 360 / Autodesk Construction Cloud-hosted models work as long as Revit can open them.

When the code fails with an error, AllAddin asks the model for a fix and runs it again, up to 3 attempts in total. Failures are tagged so the same mistake is avoided next time you ask a similar question. If the code runs but the result is not what you meant, say so in the chat and AllAddin adjusts it; Revit's Undo reverts the change.

Yes, if you want it. Switch on Plan-my-Prompt to see the step-by-step plan before any code runs; a preview-and-confirm step for model changes can also be enabled. By default AllAddin runs the code straight away and shows it in the chat panel with the result.

AllAddin is a product of MeliUX Ltd, a UK-registered company. MeliUX Ltd is run by Rene Pellicer Garcia, an Autodesk Expert Elite member with 25+ years in the AEC industry. Made with real passion, in Charlton, south east London. See https://alladdin.dev/terms for the full legal entity details.

No. AllAddin is a software product - an AI cooperator agent for Autodesk Revit - made by MeliUX Ltd in the UK. The name is a pun on "all" + "add-in" (Revit plugins are called add-ins). AllAddin is not affiliated with, sponsored by, or endorsed by The Walt Disney Company or any Aladdin film franchise. The canonical website is https://alladdin.dev.

Because the name is "all" + "add-in" - the two L's are load-bearing. AllAddin (two L's) is a Revit AI product made by MeliUX Ltd. Aladdin (one L) is the Disney character. Search results may confuse the two; the canonical site for the AllAddin product is https://alladdin.dev.

"All" + "add-in." Revit plugins are called add-ins; AllAddin behaves like the union of every add-in a Revit user might want, driven by an AI agent that lives inside Revit. Users of AllAddin are called "Allies" - the pun continues. AllAddin is made by MeliUX Ltd in Charlton, south east London.
