The Problem Every BIM Team Knows Too Well

Ask any architect or BIM manager where their time goes, and the answer is always the same: repetitive tasks. Sheet creation. Tagging. Dimensioning. Version management. Documentation that should take minutes but somehow consumes days.

Architects can spend over half of a project's timeline on detailed modeling and documentation, leaving less than half the project for actual design thinking. Meanwhile, every project closes and its hard-won knowledge is closed out, too. The details that worked, the standards that held up, the decisions that took hours to coordinate—all now buried in old models, or locked in folders no one can navigate.

This isn't a knowledge problem. It's an operationalization problem. Pirros built Mira to solve it.

What Is Mira? The AI Agent for Revit, Explained

Mira is Pirros's AI engine. Mira's most visible expression is a conversational AI agent that lives inside Revit. Built on frontier AI models and tested by real designers on real projects, this Revit agent goes beyond a standard API integration. It uses dynamic tools and purpose-built skills trained specifically on design production workflows.

The result: Mira outperforms the native Revit AI assistant on every benchmark test.

Rather than clicking through menus, writing scripts, or building Dynamo graphs, teams simply describe what they need. Mira interprets the request and executes it. This is what a true AI co-pilot for architects looks like in practice—not a chatbot bolted onto existing software, but an agent embedded in the workflow itself.

Why "Mira"? The Meaning Behind the Name

The name isn't arbitrary. In Latin, mira means "to see." In its reflective form, it means "to mirror."

The name was deliberately chosen: Mira sees the firm, not just the file. It mirrors the firm's collective intelligence—every detail, every family, every standard, every project decision—and makes that intelligence available to every designer on every future project, across discplines and offices.

Most AI tools for architecture and engineering give you access to generic knowledge. Mira gives you access to your knowledge. That's the difference.
‍

Five Mira Capabilities That Transform Revit Workflows:

1. Natural Language Control in Revit

Talk to Revit. Describe a task in plain language like place a wall assembly, tag elements across multiple views, set up sheets for a new design option—and Mira executes. This is BIM automation without the learning curve of scripting or visual programming. Teams who have never written a line of code can now automate complex Revit sequences.

This is what the AE industry has been waiting for: a Revit AI plugin that actually understands design intent, not just commands.

Available now for any Revit user. Start for free. Even if you're not a Pirros customer.

2. Detail & Family Health Scores

A standard library tells you what should be good. Mira's health scores tell you what actually is. Mira evaluates every family and detail in your library and across every project—analyzing file size, parameter count, geometry, annotation style, and custom criteria you define—then assigns a score and an explanation. You see the grade, you see the reason, and you know exactly what to fix to raise it.

No more guessing whether a detail from three years ago is still up to standard. Mira tells you.

Available now within Pirros.

3. Auto-Sync to Latest

Revit model content drifts out of sync with the master library. Families get updated in the library, but the version already placed in an active project stays frozen. Auto-Sync to Latest closes that gap automatically.

Point Mira at any Revit model connected to your Pirros workspace and it identifies every detail and family that has a newer version in the library, shows you what changed, and lets your team update with one click. Think of it as a "check for updates" button for your entire Revit model—one of the most powerful Revit productivity tools available today.

Available now within Pirros.

4. Multi-Version Intelligence

Migrating from one Revit version to another? Converting your full library the traditional way (opening each file, saving to the new version, re-uploading) is a massive project on its own. Multi-Version Intelligence eliminates that entirely.

Select a single item or batch, choose any Revit version as the target, and Mira runs the conversions in the cloud. Every detail in Pirros now carries multiple Revit year versions, all stored alongside the source. This is BIM automation at the library level: infrastructure work handled automatically so your team never has to touch it.

Available now within Pirros.

5. Sheet Builder

Your details are already in Pirros. Sheet Builder lets you drag, position, and configure them into a sheet layout before you ever open Revit. When you're ready, download it and Revit creates the sheet automatically with every detail exactly where you placed it.

Because the layout lives in Pirros, it's reusable. Build a standard wall section sheet once, use it on the next ten projects, version it, and share it across offices. Sheet setup transforms the repetitive manual work into a reusable asset. This is Revit workflow automation at the documentation phase, one of the most time-consuming stages of any project.

Available now within Pirros.

Mira as Infrastructure: A Brain That Sees the Whole Firm

The five capabilities above are powerful on their own. Together, they represent something bigger.

Pirros made a deliberate choice not to build one thing really well and call it done, such as a detail manager, a family library tool, a QA checker, etc. Any single one of those would be useful, and plenty of companies have built them. Instead, Pirros built the connective tissue between all of them.

Mira is that connective tissue. Firm-specific intelligence built from your actual work. Your details, your families, your standards, your project history—all running underneath every Pirros product and making them stronger together than any one could be alone.

The best AE firms don't just do great design work. They build systems that let them do great design work consistently across projects, across teams, across years. The knowledge earned on one project should compound over time, not disappear when the project closes or a senior person leaves.

Mira is the infrastructure for that compounding advantage.
‍

Who Mira, the AI Engine, Is Built For

Architects who are tired of spending more time on documentation than design. Mira handles the repetitive modeling and annotation so you can focus on design intent and client work.

BIM managers who need to enforce standards without becoming a bottleneck. Mira embeds QA/QC into the workflow, scores content against your firm's criteria, and keeps models in sync with the master library—automatically.

Engineers who move between Revit versions, manage large family libraries, and need their institutional knowledge to travel with the project, not disappear after closeout.

Design technologists who want the power of Dynamo-level automation without requiring every team member to learn visual programming. Natural language is the new interface.
‍

How Mira Compares to Other Revit AI Tools

There are other AI plugins for Revit on the market. What sets Mira apart is its foundation in firm-specific knowledge and production-tested design workflows.

Generic AI tools give you access to AI. Mira gives you access to your firm's AI—trained on your details, calibrated to your standards, embedded in the platform where your content already lives. It's not a standalone Revit add-in stitched onto existing software. It's an intelligence layer built into the ecosystem where teams already manage their work.

And unlike tools that require upfront library curation, manual tagging or rigid naming conventions, Mira's underlying platform—Pirros—uses AI and computer vision to automatically organize Revit content by geometry and composition. Your entire project history becomes searchable instantly, without migration or restructuring, and without the manual labor that makes most content management initiatives stall.

Thousands of leading design teams around the world have trusted Pirros to manage their details, families and standards across projects, team and offices since 2022. Now that same intelligence works inside Revit, and responds in plain English.

The Bottom Line: AI for Revit Has Arrived

The era of intelligent BIM automation is here—not as a future promise, but as working software you can open today.

Mira doesn't ask your team to change how they work. It asks Revit to do more of the work for them. Natural language control. Automated health scoring. One-click version sync. Cloud-based multi-version conversion. Reusable sheet layouts. Five capabilities, one AI engine, built specifically for the way architecture and engineering firms actually produce work.

If you're a BIM manager looking to streamline Revit workflows, an architect tired of repetitive documentation, or a design technologist searching for the best AI plugin for Revit in 2026 and beyond, Mira is worth a serious look.
