Pin voice, photo and video notes onto plans, site photos and 3D models — construction site reporting from your phone. PinMy is a mobile-first visual collaboration app for construction and AECO teams. Open a PDF plan, a site photo, a walkthrough video or a 3D IFC model, tap the exact spot where the issue is, and leave a voice note, photo, video or text right there. Voice notes are transcribed automatically and become searchable — so the person who wasn't on site can still find what was said, and exactly where. Everything captured on site exports as a PDF report in one tap: all of it, or filtered by status, assignee or day. Issues also move in and out of the BIM stack through BCF 2.1 import and export, so PinMy extends the tools the office already runs instead of replacing them. Uploaded IFC models are converted to a lightweight format that actually performs on a phone or tablet. PinMy replaces the chain most site teams still live with — camera roll, WhatsApp groups, paper markups and a spreadsheet typed up at night. Every note becomes a dated, located, attributed record: which defect, on which plan, at which point, said by whom. That matters on the day a dispute starts. No training, no desktop CAD, no BIM license. If someone can send a voice message, they can use PinMy. Free forever for individuals; Premium is €8.99/month + VAT. Available in 8+ languages on iOS, iPadOS, Android, the web and as a Chrome extension. EU-hosted, GDPR-aligned, encrypted in transit and at rest — your content is never used for AI training and never sold.
