Mappa
Annotate construction plans in the browser
The problem
Mappa is a browser-based job mapping tool built for annotating construction plans and documents. Upload PDFs or images, highlight areas on plans, attach sectioned notes to specific regions, and export your mapping work as CSV or PDF. All project data is stored locally in your browser — nothing leaves your machine unless you export it.
How it works
Real tasks and outcomes — not a generic feature list.
- 1
Upload your plans
Drop in PDFs or images from your project folder. Mappa opens them in the browser — no plugins or desktop installs required.
- 2
Highlight and annotate
Draw highlights around areas of interest, attach sectioned notes to specific regions, and build a clear record of what was found where.
- 3
Export your mapping work
Download your annotations as CSV for further analysis or as PDF to share with the team, client or site records.
Key features
Browser-based
Open plans in any modern browser. No installation, no plugins.
Sectioned notes
Attach notes to specific highlighted regions so context never gets separated from location.
Local storage
Project data stays in your browser. You control when and what gets exported.
CSV and PDF export
Share annotated work in the format your workflow needs.
Who it is for
Site managers, estimators and project teams who need to mark up plans, record observations and share annotated documents without desktop CAD software.
- Mark up plans without installing specialist software
- Keep notes attached to the exact area they refer to
- Export annotated work for site records or client updates
