Chat with the model you have open — change families, fix naming, match schedules, and put the building code to work, in plain language inside Revit.
Give 99 a task in plain language. It reads the model you have open, tells you what it's about to do, and does it — with every change reviewed and undoable.
Fix the tags and bring every room's color scheme in line across a whole level, from one instruction.
Rename thirty sheets and views to the project standard in one pass — and see the change list before it applies.
Swap every door of one family for the approved type — proposed first, applied as one undoable step.
One conversation connects your live Revit model and the building code — so a question turns into reviewed work without switching tools.
Explore the Revit add-in →Rooms, doors, walls, levels, and any parameter — read live from the open model
Hundreds of elements changed in a single reviewed, undoable transaction
Built and exported straight from the live model
Missing data, naming conventions, and firm standards caught before a set goes out
Answers with clause-level citations you can verify in place
A generic chatbot can only talk about your project from what you paste into it. 99 is wired into Revit's own API: it sees the actual elements, reads their actual parameters, and when you approve a change it makes that change in the model — then you keep working. The difference is between advice and work.
99 Studios is built by a designer-engineer who wanted the assistant to live where the model lives.
Design teams use 99 to swap scattered tools for one AI workspace. These are the questions we hear most.
99 is an AI workspace for building designers: it connects your live Revit model and the building code in one chat, so you can run edits, keep checks moving, and cite sources without switching tools.
Every code answer names the exact section it came from. Hover a citation and the clause text opens right there, so you verify the answer without reaching for the code book.
