In-Depth Review: Pirros
What It Is
A platform that ingests a firm's Revit models and makes the details, families, standards, and model groups inside them searchable by what is drawn, plus Mira, a natural-language agent that runs multi-step work inside Revit, and a quality system that reviews a project set against firm standards, specs, and code.
Who It's For
Architecture and engineering firms with years of past projects nobody can search, and BIM managers who maintain content libraries that go stale the moment the person maintaining them moves on.
Why It Matters
Every content library before this one depended on someone tagging things correctly and keeping it up. Pirros indexes what is actually drawn, using computer vision to read geometry and annotation, so a detail is findable by the condition it shows rather than by whatever it was named in 2019. That removes the curation work that kills most firm libraries in their second year.
Problem Solved
A firm has drawn the same wall base condition two hundred times and cannot find any of them, so someone draws it again. Pirros ingests whole models rather than asking a person to add and tag content, then lets anyone search by the condition. Mira takes the repetitive Revit work around that, running sheet setup, bulk parameter edits, renumbering, and tagging from a plain sentence, and a prompt that works can be saved as a named skill the rest of the firm reuses. The quality system reads a project set against the firm's own standards and flags what departs from them, citing the sheet and the standard on each finding.
Audience Fit
Primary Users:
- BIM Manager
- Architect
- Engineer
- Designer
Ideal Fit:
- Firms with a large Revit back catalogue and no way to search it
- Practices whose content library depends on one person to stay alive
- Teams doing repetitive Revit production work worth automating
- Firms needing SOC 2 Type II from a vendor holding their drawings
Key Differentiator
Finds content by what is drawn, with no tagging or naming conventions
Workflow Fit
Project Phases Covered:
- DD
- CD
- Construction Docs
Where It Plugs In:
Sits beside Revit. Content is pulled from models automatically or through Autodesk Platform Services, and staff search and place from a panel inside Revit. Mira installs separately and works on the active model.
User Experience
Speed: Search runs against an index built from the models rather than the files, so results do not depend on how anything was named
Interface: A web app plus a dockable pane inside Revit. Mira adds a chat that proposes a plan, executes, then captures an after-screenshot to show what it did
Learning Curve: Gentle to search. The work is in the initial ingestion and in deciding which firm standards the quality system should enforce
Collaboration: Shared workspaces including guest access for joint ventures and consultants, with SSO and SCIM provisioning through Azure AD
Integrations: Two Revit plugins in parallel covering Revit 2020 through 2027, a separate Mira installer for Revit 2025 to 2027 on Windows, Autodesk Platform Services ingestion, and an ACC and BIM 360 app
Bonus Insight
Mira's limits are sharper than the marketing suggests, and they are geographic as well as technical. It needs Windows and Revit 2025 or later, so Revit 2024 and earlier are out, and sign-in works only in the United States, Canada, the United Kingdom, Mexico, Australia and New Zealand, and Italy. That excludes most of Europe and all of Asia, which matters for any firm with international offices. Mira also has no admin role or firm-level permission model yet, so a firm cannot centrally govern who uses it or how, which is the first question IT will ask. Two plugin generations run side by side and the newer dockable pane is enabled firm by firm, so confirm which one you get. Worth crediting: the company states on its own platform page that the real-time co-editing shown in an illustration has not shipped, and labels another illustration as invented for the page, which is rarer than it should be. The security posture is unusually strong for a 44-person company, with a real SOC 2 Type II rather than a badge, a named auditor process, and an explicit no-training commitment. The strongest evidence that the search actually works is that Lake Flato ran a year-long parallel trial against Autodesk Content Catalog, AVAIL, and Hive before choosing it, though that case study is published by Pirros. The 400-plus firm count and the 30 hours saved per project are the company's own figures. ENR independently reported 300 customers and 15,000 users in December 2025.
