PinMy - Site Plans & PDF Markup

PinMy is a mobile-first visual collaboration app for construction and AECO field teams. It turns the phone already in a site worker's pocket into the fastest way to document what is actually happening on site — and into a defensible record of it afterwards.

The problem it solves is not a lack of software. It is that field data is still born in the wrong place. Observations start as paper sketches, camera-roll photos and voice messages scattered across a dozen WhatsApp groups, then get re-typed into reports, emails and spreadsheets hours later, usually by someone who was not there. What survives is unstructured, unsearchable and difficult to defend when a dispute begins. Meanwhile the office cannot see the site until days after the fact.

PinMy closes that gap at the moment of capture. 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, text or PDF right there. The same one-tap gesture works on every file type. Voice notes are transcribed automatically and become searchable, which matters when the person who needs the information was never on site.

Because uploaded IFC models are converted to a lightweight format optimised for mobile, 3D coordination stops being a desktop-only activity. A site engineer can walk the model where they are standing, on a phone or tablet, without a workstation or a BIM licence.

Issues move in and out of the wider stack through BCF 2.1 import and export. A defect pinned on site opens as a BCF issue in the desktop BIM tool or CDE, and the office response comes back the same way. PinMy is designed as an extension of an existing toolchain, not a replacement for it — we do not compete with Procore, Autodesk or Revit.

Everything captured exports as a PDF report in one tap: the full record, or filtered by open and closed status, by assignee, or by day. The evening spent assembling a report from photos and memory disappears.

Additional capabilities include OCR on site photos for pulling text from labels, panels and serial numbers; annotation on video at the exact frame and point; freehand sketching on plans and photos; threads, statuses, assignees and mentions attached to the pin rather than buried in a chat scroll; and a geolocated map of every project.

Adoption is the design constraint. Field teams have low tolerance for training and high tolerance for WhatsApp. PinMy is built so that anyone who can send a voice message is productive within minutes, with gloves on, in noise and in bad light. That is the reason it gets used after week one.

PinMy runs on iOS, iPadOS, Android, the web and as a Chrome extension, in 8+ languages, and is rated 4.8 stars on Google Play. It is free forever for individuals with no credit card required; Premium is €8.99 per month plus VAT, with two months free on annual billing; a Teams tier with custom storage, integrations, white-label, SSO and audit logs is available on request. Data is EU-hosted, GDPR-aligned and encrypted in transit and at rest. Customer content is never used for AI training and never sold.
