1. Import trees

CompPhy's data is organized in projects in which you can import up to two collections of trees in Newick format. Collections can contain a large number of trees. Trees can have branch lengths and supports.

2. Invite collaborators

You can create public or private projects and invite people to join them. Each project is stored online and can be accessed from anywhere with any device having Internet facility.

3. Work on the project

CompPhy implements various tools to help you display and compare trees: coloring, rerooting, (automatic) swapping, restricting to common taxa, computing supertrees, etc.
