PinMy is a mobile first construction field documentation and collaboration platform designed for architects, site supervisors, BIM coordinators, foremen, project managers, surveyors, facilities managers and other field teams.
The platform addresses a common problem on construction sites: important information being scattered across WhatsApp messages, emails, photographs and handwritten notes. With PinMy, users can place a pin directly on the relevant location of a PDF plan, site photograph, map, walkthrough video or 3D IFC model and attach the information to that exact location.
A pin can contain a voice note, photograph, video, text comment or other supporting material. Voice notes are automatically converted into searchable text using AI transcription. Premium users can also use AI powered OCR to extract printed information such as serial numbers, equipment labels and text from photographs.
PinMy also supports assignments, status tracking, freehand sketching, PDF reporting and BCF workflows for BIM teams. It is available on iPhone, iPad, Android, web browsers and through a Chrome extension.
Rather than attempting to replace large construction management platforms, PinMy focuses strongly on capturing information at the moment something is observed on site.
Features
Voice Notes on Plans
Users can place a pin at a specific location on a plan and record a voice note explaining an issue, observation or instruction. This is useful when typing detailed information on a construction site would be inconvenient.
AI Voice Transcription
Voice comments are automatically converted into searchable and editable text. PinMy currently supports voice transcription in more than 20 languages.
Pins on PDF Plans
Construction drawings and PDF plans can become interactive working documents. Users can place pins exactly where defects, changes or other observations occur.
Photo Annotation
Site photographs can be uploaded or captured through the application. Teams can pin comments and supporting information directly to specific areas of an image.
Video Annotation
Premium users can upload walkthrough videos and place comments at specific moments. This can help teams document issues discovered while moving through a construction site.
3D IFC Model Support
PinMy supports IFC files. The platform converts an uploaded IFC into a lightweight 3D model that can be opened on a mobile device.
Users can then place pins directly on the 3D building model and attach voice, text, photographs, videos or documents.
BCF Import and Export
BIM teams can exchange issues using BCF 2.1 files. This allows information to move between PinMy and BIM applications such as Revit, Navisworks and Solibri. BCF functionality is currently presented as a beta feature.
AI OCR
Premium users can use optical character recognition powered by AI to extract printed text from site photographs.
This can be useful for capturing serial numbers, equipment labels, nameplates and printed information without manually typing every detail.
Freehand Sketching
Users can draw directly over plans and photographs. They can circle defects, highlight areas requiring attention or sketch proposed changes.
Photos Inside Pins
Site workers can photograph a problem while working within a pin, keeping the visual evidence connected to the exact location and discussion.
Tasks and Assignments
Pins and observations can be turned into actionable work. Team members can be assigned tasks and follow them through different stages of completion.
Kanban Workflow
PinMy provides a Kanban style workflow for following assigned work from To Do through In Progress to Done.
Comments and Replies
Team members can discuss an observation within the pin itself. Replies remain connected to the original location rather than disappearing inside unrelated messaging conversations.
PDF Reports
PinMy can create PDF reports containing pins, comments, timestamps and relevant context. Item Reports can be generated directly from individual files without requiring tasks to be assigned first.
Reporting functionality is currently in beta.
Interactive Project Map
Projects can be geolocated on an interactive map, helping users access information from different sites.
Guest Mode
Contractors and clients can access shared material through a browser without necessarily installing the application or creating an account.
Chrome Extension
The PinMy Chrome extension allows users to capture screenshots and send them directly into PinMy for annotation and collaboration.
Cross Platform Access
PinMy works on iOS, Android and modern web browsers, allowing field workers and office teams to work with the same project information from different devices.
How It Works
First, users create a PinMy account and upload a construction plan, PDF, photograph or supported 3D IFC model.
On site, the user opens the relevant file and taps the exact location where an issue or observation has been identified.
A voice note, text comment, photograph, video or other supporting information can then be attached to the pin.
If a voice comment is recorded, PinMy automatically transcribes the speech into searchable text.
Users can also sketch directly on plans or photographs to visually highlight defects, installation problems or required modifications.
The relevant contractor or team member can be tagged so they receive the observation with its location and context intact.
Assignments can be followed through the Kanban workflow when task tracking is required.
As work progresses, team members can add comments and update the status.
When documentation is required, users can generate PDF reports containing the recorded information.
BIM teams can also work with IFC models and exchange issues through BCF workflows.
Use Cases
Site Supervisors: Supervisors can document defects, inspections and quality issues while walking through a construction site.
Architects: Architects can annotate plans, photographs and models during site inspections and design reviews.
BIM Coordinators: BIM teams can bring IFC models to the field, place observations directly on the model and exchange issues through BCF.
Construction Foremen: Foremen can keep field instructions and discussions attached to the relevant location instead of relying heavily on separate WhatsApp conversations.
Snagging Teams: Defects can be photographed, pinned, assigned and tracked until they are resolved.
Project Managers: Managers can remotely review field observations and monitor work recorded by site teams.
Property Surveyors: Surveyors can photograph observations, pin them to relevant locations and prepare PDF reports.
Telecom Teams: Installation issues can be documented on site photographs, maps and plans, while OCR can help capture equipment labels and serial numbers.
Facilities Managers: Maintenance problems can be marked directly on floor plans or photographs and documented without creating a complicated workflow first.
Contractors: Contractors can receive clearly located issues and respond within the same visual context.

Strengths
PinMy’s main strength is its visual approach to field documentation. Information is connected directly to the location where an issue exists rather than stored as an unrelated message or photograph.
Voice first documentation is particularly useful on construction sites where typing lengthy descriptions on a phone may be impractical.
Automatic multilingual transcription turns those spoken observations into searchable written records.
Support for PDFs, photographs, videos and 3D IFC models allows teams to use a similar annotation workflow across several common construction file types.
Its BCF functionality is useful for BIM teams that need field information to move between mobile workflows and professional BIM applications.
Another advantage is the permanent free plan, which allows small teams and individual professionals to test the core workflow without providing payment information.
Drawbacks
PinMy is specialized for construction, architecture, engineering, property and field operations, so it is less relevant to general business users.
Several useful capabilities, including video annotation and OCR, require the Premium plan.
The Free plan has relatively small file and storage limits, which may become restrictive for projects containing many drawings and photographs.
Some reporting and BCF capabilities are currently marked as beta features.
PinMy’s own documentation notes current report limitations. Reports work on individual files rather than entire folders, and features such as custom report templates, client logos, electronic signatures, priorities and due date columns are not currently available in the described reporting workflow.
AI generated voice transcriptions and OCR results may also contain errors. Important engineering, safety, legal and compliance information should always be verified by qualified professionals.
Comparison with Other Platforms
Compared with general messaging applications such as WhatsApp, PinMy provides much stronger context for construction communication because observations remain attached to exact locations on plans, photographs and models.
Compared with general purpose note taking applications, PinMy is specifically designed around field documentation and construction workflows.
Compared with larger construction platforms such as PlanRadar, Autodesk Construction Cloud, BIM 360 or Procore, PinMy describes itself as a mobile first field authoring layer rather than a direct replacement for every enterprise construction management function.
This approach can make it useful alongside an existing Common Data Environment. Field teams can capture structured information through PinMy before that information moves into a larger project management or BIM system.
For smaller and mid sized teams, its combination of visual pins, voice transcription, tasks and reporting may also cover many everyday site documentation requirements without the complexity of a larger enterprise platform.
Customer Reviews and Testimonials
PinMy features several user testimonials on its official website.
Sebastian, an Architect and BIM Consultant from Canada, highlights the ability to annotate plans, share feedback and maintain collaboration across devices while supporting paperless workflows.
Other testimonials displayed by PinMy come from professionals in different countries and construction related roles, reflecting the platform’s focus on practical field collaboration.
These testimonials are published by PinMy itself, so organizations evaluating the platform should also test the Free plan and consider independent user feedback before adopting it for larger projects.
Conclusion
PinMy is a practical field documentation platform for construction and AECO professionals who want to keep site observations connected to the exact place where they happen.
Its combination of visual pins, AI voice transcription, photographs, videos, freehand sketches, tasks, PDF reports, IFC models and BCF workflows provides a more structured alternative to storing important construction information across messaging applications, notebooks and disconnected photographs.
Site supervisors, architects, BIM coordinators, snagging teams, surveyors and project managers are likely to gain the most value from the platform. The permanent Free plan also makes it easy for an individual or small team to test the workflow before moving to Premium or discussing a larger Teams deployment.
