Mirage vs SWAPP
SWAPP and Mirage work on opposite sides of the same drawing set. SWAPP, according to its site, automates documentation and modeling for architecture firms inside Revit and ArchiCAD: it produces the construction document set. Mirage produces no drawings at all. It reads the set once it is issued, for the contractor who has to price it, check it and build from it. If you are an architect looking for a SWAPP alternative, Mirage is not one.

Short answer
An architecture firm that wants AI to draft its construction document sets should compare SWAPP with other documentation tools that run inside Revit and ArchiCAD; Mirage authors nothing. A contractor that receives those sets and needs a takeoff, a clash check, a revision comparison or a spec review from them is where Mirage fits, whichever tool drew them.
Executive Summary
SWAPP describes itself as AI architectural documentation and BIM automation. Its agentic assistant, Frank, works inside Revit and ArchiCAD. The platform produces complete construction document sets (dimensions, tags, views, sheets) to the firm's own standards, models from schematic design through construction documents, and validates every output against the firm's QA rules before delivery. Its site speaks to project architects, BIM and design technology leaders and firm leadership, and has a section for contractors and owners about design intelligence that carries into the field.
Mirage Metrics builds and operates AI agents for contractors' document work. Its engineers deploy agents that read the issued drawings (PDF and DWG sheets, scanned or vector, and IFC where a model exists) and return a takeoff, the clashes and inconsistencies across disciplines, the changes between two revisions, or the spec clauses that conflict with the drawings, each result traced to its sheet.
The overlap is small. Both products have to understand drawings and models: SWAPP uses that to write the set, Mirage to read a set somebody else wrote. A design firm can use SWAPP and its general contractor can use Mirage on the same project without either tool touching the other.
Key Takeaways
- SWAPP drafts construction document sets and models for architecture firms, inside Revit and ArchiCAD. Mirage authors nothing.
- Mirage reads the issued set for the contractor: takeoff, clash detection, revision comparison, spec review.
- The overlap is drawing understanding, used to write the set on one side and to check it on the other.
- A design firm on SWAPP and a contractor on Mirage can work on the same project with nothing to integrate.

Key Differences
Writing the set, and reading it
SWAPP's output is the drawing set itself: sheets, views, dimensions and tags, produced in the architect's model. Mirage's output is information taken from a set that already exists: quantities, clashes, revision changes, spec conflicts. One is a design production tool, the other a reading tool for the people downstream of design.
The architect's standards, or the contractor's checks
SWAPP learns a design firm's annotation rules, graphic standards and QA logic, and enforces them on every project. Mirage is built around what a contractor checks before pricing or building: whether the quantities add up, whether the disciplines agree, what changed since the last issue, what the spec says that the drawing does not.
Inside the authoring tool, or on what was issued
SWAPP works in the live Revit or ArchiCAD model of the firm that owns it. The contractor rarely has that model: it receives PDFs, sometimes DWG, sometimes an IFC. Mirage works on those files as they arrive, scanned or vector, without the native model and without a license for the tool that drew them.
Advantages and Limitations

- Every quantity and every flag traced to its sheet, detail or clause
- Built and operated with your team by engineers, around the checks it already makes
- Covers contractor workflows: takeoff, clash detection, revision comparison, spec review, bid leveling
Limitations
- Authors no drawings, models or construction document sets
- Not a Revit or ArchiCAD add-in
- Each workflow is a deployment, 4 to 6 weeks to the first one in production
- Does not check drawings against building codes, and publishes no security certification
SWAPP
Advantages
- Produces construction document sets inside Revit and ArchiCAD
- Modeling from schematic design through construction documents
- Enforces the firm's own standards and QA rules on every output
- Credit-based usage with a free start, and ISO/IEC 27001:2022 certification, according to its site
Limitations
- Built for the firm that authors the model, in Revit or ArchiCAD
- Not presented as a takeoff, estimating or bid leveling product
- No credit prices published on its pricing page
Real-World Use Cases
An architecture firm behind on CD production
Sheets, views, dimensions and tags to produce to the firm's standards, in Revit or ArchiCAD. That is SWAPP's case, or another documentation tool's. Mirage has nothing to offer here.
A contractor pricing a bid set
The set arrives as PDFs, some scanned. Mirage produces the takeoff from the whole set, each quantity traced to its sheet and detail, exported to Excel or your estimating system. The estimator reviews instead of measuring.
A revision lands mid-bid
Mirage compares the two issues and lists every change with its sheet, its location and the quantity difference, so the team prices the change before it reprices the job.
Both sides of one project
The design firm drafts with SWAPP; the general contractor checks and prices the issued set with Mirage. Nothing has to be integrated: the set is the hand-off, as it always was.
Mirage Workflows
Takeoff & Estimating
Quantities from PDF, DWG and IFC drawings, each traced to its sheet, detail and spec reference, exported to Excel or your estimating system.
See the pageClash detection
Clashes across structure, architecture and MEP, references and specs, flagged on the sheets before they become RFIs.
See the pageDrawing revision comparison
Every change between two revisions flagged with its sheet, its location and the quantity difference.
See the pageSpecification review
Spec clauses cross-referenced against the drawings and checked again on every revision.
See the pageBid leveling
Subcontractor bids read as they arrive, every line matched to your scope, exclusions and price gaps flagged before award.
See the pageHow to Choose
Start with who you are on the project. If your firm draws the set, you are comparing documentation and modeling tools that run inside Revit or ArchiCAD, and SWAPP belongs on that list. Mirage does not.
If your firm receives the set, the question is what you do with it by hand today: measuring quantities, hunting for clashes between disciplines, finding what changed between issues, reading the spec against the drawings. Those are the steps Mirage takes, one workflow at a time, on whatever set the designer issued.
If you are both, as a design-build firm or an EPC contractor can be, the two tools do not compete: one produces the documents, the other checks and measures them on the construction side.
Where SWAPP and Mirage overlap
Only in understanding drawings and models. SWAPP's site describes coordination intelligence that flags clash-prone elements before the model reaches the BIM coordinator, inside the design firm's model. Mirage flags clashes and inconsistencies on the sheets that were actually issued, including the ones that never made it into a model, for the contractor. The first prevents problems while drawing; the second finds what is left once the set is out.
Where Mirage fits on US and UK projects
Whoever drew the set, the contractor's documents around it follow different rules on each side of the Atlantic, and Mirage's construction workflows are built on those rules.
- US, specifications. Specs and submittals organized by CSI MasterFormat division, each item traced to its source. See CSI MasterFormat extraction.
- US, pay applications. AIA G702/G703 built from the schedule of values and reported progress, every line traced. See pay applications.
- UK, quantity surveying. Quantities taken from the drawings into an NRM2-structured bill of quantities, each line traced to its source drawing. See NRM quantity surveying.
- What Mirage does not do. It does not check drawings against building codes and does not verify the engineering itself; the designers keep that judgement.

FAQ
Not for an architecture firm. SWAPP drafts construction document sets and models inside Revit and ArchiCAD; Mirage produces no drawings or models. Mirage is an alternative to the manual work a contractor does on the issued set: measuring quantities, checking for clashes, comparing revisions and reading the spec against the drawings.
Tools that draft documentation inside the authoring software, to the firm's standards, which is the category SWAPP's own site describes. This page does not rank them. For the stage before documentation, Snaptrude presents itself as browser BIM for feasibility, massing, program and schematic design, with export to Revit when documentation begins.
Mirage reads issued sets as PDF or DWG sheets, scanned or vector, and IFC where a model exists, whatever tool produced them. No integration with SWAPP is claimed or needed: the issued set is the hand-off.
No. Mirage reads drawings and documents that already exist and returns quantities, clashes, revision changes and spec conflicts, each traced to its sheet. It authors no sheets, no views and no model.
Its site, read on 3 November 2026, presents documentation, modeling and QA for architecture firms, not takeoff or estimating. Ask SWAPP directly if that matters to you.
SWAPP's pricing page describes a credit-based system where you pay for what you use, a free start for Frank and enterprise plans for multi-office firms, with no amounts published. Mirage starts with a proof of concept on your own documents one week after the first meeting, then a fixed-price pilot: from $10,000 to launch, then an annual subscription from $1,000 a month, priced by volume.
