The spec database for the built world.

Every construction project runs on specifications — load ratings, dimensions, wind resistance, install requirements, warranty terms. That data exists, but it's scattered across hundreds of manufacturer websites, PDF catalogs, and spec sheets that are slow to find and hard to compare.

Jaspecs consolidates that data into a single, searchable database. Search by product name, SKU, or manufacturer and get the technical spec page in seconds — no PDFs, no paywalls, no account required.

We currently index 1,000,000+ SKUs across 200+ brands and 2,000+ product lines, covering roofing, windows, doors, HVAC, structural components, and more.

Jaspecs is a companion product to Jaspector — a construction knowledge platform that helps homeowners navigate permits, contractor licensing, contracts, and project disputes across 24,000+ jurisdictions.

Where Jaspector helps you understand the process of building — who to hire, what permits you need, how to protect yourself — Jaspecs gives you the raw technical data on the materials themselves. Together they cover the full arc of a construction project: the paperwork and the products.

AI search engines — Google, Microsoft Copilot, Claude, Perplexity — are increasingly the first place people go when they need a product specification. The problem is that most spec data is locked inside PDFs and behind manufacturer login walls, invisible to these systems.

Jaspecs makes that data accessible and structured so that when someone asks an AI assistant "what is the R-value of Owens Corning EcoTouch R-38?" — the answer comes from a reliable, citable source.
