BidcoreAI vs CostX: Two Installed Estimating Programs

CostX is a long-established takeoff and cost-estimating package with 2D and 3D/BIM measurement. BidcoreAI is installed software too, built around the whole bid: tender documents, takeoff, estimate, subcontractor packages and the proposal, with AI that cites its sources.

BidcoreAI vs CostX: What It Is and Why It Matters

CostX, developed by Exactal and now sold under the RIB name according to current listings, supports 2D drawings and 3D/BIM models (Revit, Archicad, IFC and others), live-linked estimating workbooks, revision comparison and multi-user use. It is a strong choice when model-based takeoff is central to your work.

BidcoreAI works from PDF drawings. What it adds is everything around the measurement: reading and qualifying the tender, pricing from your own cost data, packaging scope for subcontractors, levelling their quotes and drafting the proposal, with AI that shows the page behind each finding.

Estimating	Assemblies, your cost database, CSI	Live-linked workbooks and reports
Bid packages, ITBs, levelling	Built in	Not a focus of its public material
Proposal drafting	Built in	No
AI	Reads documents and drawings, cites sources; your own agent with approval	Not AI-led
Where it runs	Your Windows computer or server	Installed software
Federal Go/No-Go; India CPWD / MoRTH	Yes	No

Choose BidcoreAI when

You bid from PDF drawing sets and want one flow to the proposal
You need subcontractor coverage and quote levelling
You want AI that cites sources, running locally

CostX may fit better when

Your takeoff comes from 3D/BIM models
You are a quantity surveying practice working mainly with measurement workbooks
Your team already runs CostX and BIM-based workflows

Compare them on one project

1. Use one tender. Take a real drawing set and its documents.
2. Measure in each. Compare how long takeoff takes and how easy corrections are.
3. Follow the bid through. Packages, quotes, proposal.
4. Count the re-entry. How often did you retype the same numbers?

BidcoreAI vs CostX: Your Questions Answered

For PDF-based takeoff and estimating, and for the bidding and proposal work around it, yes. CostX also measures 3D/BIM models, which BidcoreAI does not.

Yes. Both are installed software rather than cloud web applications.

No. It works from PDF drawings.

Yes: a federal Go/No-Go with SAM.gov data in the United States, and tender-document analysis on bidcore.in for India.
