## What it is
Tropy is an open-source desktop application for organizing, describing, and annotating research photos, built with Electron, Node.js, and SQLite. It lets researchers turn camera images into described source items with metadata templates, tags, lists, and export to JSON-LD, CSV, Zotero, and Omeka S.

## Use cases
- organize archival research photos
- describe and catalog research sources with metadata templates
- annotate and transcribe documents in photos
- export research items to Zotero or Omeka S
- import IIIF manifests into a research workflow
- tag and list research items across projects

## When to choose
- you are a researcher working with many photos taken in archives or libraries
- you need structured metadata, tags, and annotations on research images
- you want local SQLite storage with JSON-LD/CSV export and plugin extensibility

## When to avoid
- you need general-purpose photo editing or consumer photo library management
- you need cloud-based or multi-user collaborative photo management
- you only need lightweight image viewing without metadata workflows

## Facets
