Frequently asked questions
Can I publish a caption directly?
No. Tervix creates a local draft that you can copy, review and adapt before publishing.
Does Tervix connect to or publish on my accounts?
No. It requests no credentials, accesses no profiles and publishes nothing automatically.
Should I review the result?
Yes. Review text, links, dimensions and current platform rules before using it.
