Practical tools for offices and trades.

Paper Mason is a local-first paperwork cleanup app for small offices and home-office users. Drop in a batch of PDFs or scanned images and Paper Mason renames, sorts, and OCR-checks them on the device — no upload required. It is built for reviewable document hygiene: templates you start from, filenames you confirm before they are applied.

BidRivet is an HVACR-first estimate builder for trade techs who are also salespeople. It is built around a short, constrained flow — job type, equipment, add-ons, review warnings, send — backed by deterministic money math and explicit owner-controlled rules. The point is not to replace a full field-service suite; it is to keep the math correct in the field.
