Checked on September 20, 2026 from each product's public pages. Something wrong or outdated? Write to hello@teserra.app and we fix it.
if you work on Windows, or need the largest plugin ecosystem today.
if you want a free-form canvas and an iPhone companion right now.
if you want everything in the cloud, on every device, and a subscription does not bother you.
if your files must stay yours in plain folders, if you want AI that runs on your Mac, and if your agents should be able to read your library.
Point Teserra at your .library folder. Folders become collections, tags stay tags, notes and palettes come along. Your originals are copied into a plain folder you own, and Eagle keeps working meanwhile.
