Tropy

Explore your research photos

Built for today’s archival research

Take control of your research photos with Tropy, a tool that shortens the path from finding archival sources to writing about them. Spend more time using your research photos, and less time hunting for them.

Turn photos into items

Tropy thinks the way you do: like a researcher. Say goodbye to IMG_5261.JPG and IMG_5262.JPG, and say hello to your sources.

Describe your sources

Tropy helps you contextualize artifacts and their photos by capturing your own subject expertise. A friendly editing interface allows customized templates that fit your research like a glove.

Organize your research

Tropy understands that every researcher is different and that every project has its own demands. Break free from the logic of the physical archive and use tags and lists to organize your research items according to your needs.
