What's New in Mira: Six Skills for the Revit Jobs You Do One Element at a Time
Our latest update to Mira makes it more powerful than ever. We've added six skills for documentation chores you'd otherwise do one element at a time.
Mira is your thinking partner inside Revit. You can ask it about your model, tell it what to change, or describe something you want built, using natural language, and Mira uses AI to do the work in Revit, while you stay in charge. It automates the work you repeat and builds the tools your team needs, and every task it learns makes the next one easier.
Our latest update to Mira makes it more powerful than ever. We've added six skills for documentation chores you'd otherwise do one element at a time: renumbering details, auditing annotation, editing text notes, setting parameters, centering room tags and flipping grid heads. Each one shows its plan first, asks before changing anything and undoes in one step.
We've also beefed up Mira's ability to plan multi-step jobs, read PDFs (not just Revit models), and keep long conversations going automatically. As always, Mira is free to download for Revit 2025 and later.
What's new in Mira
The latest version of Mira, the AI agent for Revit, builds on the earlier version we released in May 2026. If you already use Mira, you have it - here's what you'll find:
- Six new skills for documentation chores, written by Pirros and delivered from the cloud. Ask in plain words and Mira picks the right one, or choose it from the "/" menu.
- It plans multi-step jobs. Mira breaks a larger request into steps and works through them, instead of handling one request at a time.
- It reads PDFs. Give Mira a PDF and it moves around the pages the way it moves around a Revit view, pulling out the information you need.
- Long conversations keep going. Mira summarizes older parts of a long chat automatically, so there's no limit on length.
The six new skills
Each skill takes a job Revit makes you do one element at a time, and does it for you across a whole sheet, view or model in one pass.
Renumber Details on a Sheet
Late changes to a plan set will often leave a detail sheet numbered 1, 2, 5, 3, 7. Revit won't let two details on a sheet share a number, so fixing it by hand means shuffling temporary numbers.
With Mira, you simply type: "Renumber the details on this sheet." Mira draws each numbering convention on a diagram of your actual sheet before writing anything, and checks a few of your other detail sheets to suggest a match. It offers five conventions, including column-by-column order for structural sheets. Details marked SIM or N.T.S. are flagged, not overwritten.
Annotation Standards Audit
A detail from an old project or a consultant's drawing often arrives with its own line styles, text and hatches. Matching it to the rest of the plan set can be a tedious, manual process in Revit. Our guide to architectural details covers why borrowed details drift.
With Mira, just write: "Audit this view against our standards. Here's our template." Mira learns your template in the background, matches styles by their properties rather than their names, and brings judgment calls back as options with counts. It applies changes category by category, each one undoable, then summarizes what changed and what still needs a person. It never edits what a note says, and it reports a style your project doesn't have instead of inventing it.
Bulk Text-Note Edits
A product substitution can sit in notes across many views. Making the edits one-by-one in Revit can take hours.
Instead, you can tell Mira: "Replace 'Old Material Name' with 'New Material Name' in every text note." Mira searches every view, because each text note belongs to only one. It keeps each note's capitalization and asks the awkward questions first, such as whole word or part of a word. It can also merge and restyle notes, and it edits notes inside groups in place.
Bulk Set Parameters
Typing values into hundreds of elements takes a morning, and not a particularly pleasant one.
With Mira, you can instead write: "Update the door instance parameters from this table. Each row's Mark is the target." Mira converts units before writing, warns when a parameter sits on the type and would change every instance, and tells you how many elements it will touch before it writes. It fills parameters that already exist; it won't create new ones.
Flip Grid Heads
Grid bubbles often end up at the wrong end of the grid line, crowding the drawing or breaking your firm's convention, such as bubbles along the top and left. Revit sets which ends show a bubble separately in every view, so fixing it by hand means clicking each grid end, one grid and one view at a time. On a building with a plan for every level, those clicks add up fast.
With Mira, you can type: "Flip the grid heads on these grids, then do the same on the other floor plans." Mira shows a before-and-after for each grid and says which view it changed, since bubble visibility is set per view. Grids already showing both ends get a question first. Then it offers to repeat the arrangement on your other plan views.
How every skill works
Every skill follows the same four rules:
- Mira looks before it touches anything and shows you what it found.
- Nothing is written until you confirm.
- The whole batch can be undone with a single command.
- Mira checks every change afterward and names anything it skipped, with the reason.
It also knows what not to do. It won't invent a style, create a parameter, ungroup elements or guess at an ambiguous match. Those go back to you.
Why skills matter for a firm that uses AI
Asking a general AI to do the same job twice likely results in two different approaches, especially when different team members make the same request.
A skill fixes the method: the same checks, the same questions and the same report, whoever runs it. That consistency is what turns a clever result into one a project architect can sign off on. For where Mira fits among the AI tools firms use, see our guide to AI for architecture.
Teach Mira your firm's methods
You can also add your own custom skills to Mira. Just tell Mira what to remember - for example: "Write me a custom skill that tells you to follow our firm's view naming standard," and it drafts the skill for you to review and save. There's no coding or file editing. The help center walks through how to do it.
Get started in a few minutes
Download Mira with your email, open Revit on Windows, and sign in with the same email. Then open a view that needs one of these jobs and describe it in plain words, or type "/" to select an existing skill.
