Specset vs BuildSync: which AI submittal review checks your full package?

Specset (formerly Specbook AI) reviews the whole submittal, shop drawings and product data, against the governing spec section and the drawings, and returns the marked-up package with a cover sheet and your stamp (submittal review). BuildSync publishes product-by-product checks of product data submittals, plus package generation for subcontractors, and says shop drawing review is outside its scope ¹⁹. Pick Specset when packages include shop drawings or must come back stamped in the approval workflow; pick BuildSync for product data checks and subcontractor package building.
