Pelles Core

Every sheet read. Every change caught.

Pelles Core is four ready-to-run AI apps for trade contractors: answers from your drawings and specs, every change between revisions, deliverables in your own templates, and agents that do the follow-up. Ready the day you log in.

Agents do the follow‑up. You make the call.

Ready-made agents connected to Procore, Autodesk, Trimble and your inbox. They run on a schedule or when an email lands, and draft the follow-up for your team to review.

What is Pelles Core?

Pelles Core is a suite of four ready-to-run AI applications for construction: DoubleCheck (instant Q&A across project documents), Compare (automated revision diffs across sheet sets), Reports (proposals, pre-bid RFIs, BOMs, and change orders produced from your project data in your own templates), and Agents (AI agents that know your company standards and project history and work in the background). Each app is built on thousands of real construction projects and runs from day one — no model training or setup required.

What is the difference between Pelles DoubleCheck and Pelles Reports?

DoubleCheck is for ad-hoc questions — ask about any drawing, spec, contract, schedule, or addendum and get a cited answer in seconds. Reports produces finished deliverables — proposals, pre-bid RFIs, BOMs, and change orders — from your project data, in the templates you already use. Use DoubleCheck to find an answer; use Reports when the output is a document you send.

How is Pelles Core different from generic AI tools like ChatGPT?

Pelles Core is built specifically for construction document types and workflows. It reads drawings, specs, addenda, RFIs, and submittals as first-class document types and understands how they cross-reference. It cites the exact page and paragraph for every output. And customer project data is never used to train models or improve answers for other customers — a contractual guarantee generic AI tools don't provide.

Does Pelles Core integrate with Procore, Autodesk Construction Cloud, Trimble, or Microsoft Teams?

Yes. Pelles Core layers on top of your existing document storage and project management platforms — Procore, Autodesk Construction Cloud, Trimble, SharePoint, Google Drive, and Microsoft Teams. There is no rip-and-replace migration; Pelles indexes the project documents where they already live.

What types of construction companies use Pelles Core?

Pelles Core is built for trade contractors — MEP subcontractors, specialty contractors, and self-perform GCs — who process high-volume bid packages and need to extract scope, compare revisions, and generate deliverables quickly. The typical user is an estimator, project manager, or operations lead processing more than 10 bids per month.

How do I get started with Pelles Core?

Book a free demo at pelles.ai/contact. The demo runs on your actual project documents — not a generic scenario — so you can see how DoubleCheck answers questions about your real specs and how Reports turns them into the deliverables your team already sends. Most teams are running production work within a few weeks of the demo.

See Pelles Core on your own drawings.

Bring a bid set. In 30 minutes we’ll run DoubleCheck and a contradictions report on a real project from your trade.
