Phylogeny App — interactive phylogenetic tree viewer

Explore and annotate phylogenetic trees in Newick, NEXUS and phyloXML formats, or reopen a saved project. Search taxa, compare rectangular and circular layouts, and join CSV or TSV metadata.

Export figures as SVG, PNG or PDF, save tree data, or share an interactive chart with edit-later and embed links.

Start by opening a tree or choosing an example, check its taxa, add annotations, and save a project before exporting. Read the supported-format and workflow guide, including the original research references.

Enable JavaScript to use the interactive editor. The information pages remain readable without it.
