Terms of use

Last updated 25 September 2026

Twentyfirst is a private, invite-only workspace for a small group of friends. It is provided free of charge, as a personal project, and not as a commercial service. By using it you agree to these terms.

Access

You can only join by invitation. Keep your sign-in links and connected accounts to yourself. Workspace owners and admins can invite and remove members; a removed member loses access right away.

Your content

What you create stays yours. Everything in the workspace is visible to its members, except your conversations with the agent, which are private to you. Don't upload anything you don't have the right to share, or anything illegal or harmful.

The agent

The agent can make mistakes. Check what it writes, suggests or does before you rely on it, especially in connected services such as your email or calendar. You are responsible for the actions you ask it to take and approve.

Connected services

When you connect a service, your use of it is also governed by that service's own terms. You can disconnect it at any time.

No guarantees

Twentyfirst is provided as is, without warranties. It may change, be unavailable, or be discontinued. Keep your own copies of anything important. To the extent the law allows, we are not liable for losses from using it.
