Everything you should know before using Tervix
Clear answers about cost, privacy, compatibility and your local profile.
Is Tervix free to use?

Does Tervix upload my files or text to a server?
Compatible tools process files and text directly in your browser. Each tool explains its capabilities and any device or browser limitations before you use it.
