Your systems

With a free account you can keep systems on Teskooano and open them on any device. You don’t need one to watch, explore or generate systems.

Sign in

Press Sign in at the top of the site, or the account button in the simulator, and sign in with GitHub. From GitHub, Teskooano keeps only your user ID, login, name, email address and avatar. Your profile shows your plan and links to everything below.

Keep a system

There are three ways to add a system to Your systems:

  • Copy a catalogue system. On any catalogue system’s page, press Copy to my systems. The copy is yours, and it remembers which version of the original it came from. Today you change it through an AI assistant over MCP; an editor in the simulator is coming. On Free you’ll be able to build and try systems in it, and saving or downloading them will need a paid plan.
  • Import a file. On Your systems, choose a system file (.json) and press Import. That can be a Download from this site, or a system made by an AI assistant over MCP.
  • Build one with an AI assistant. Connect Claude or another assistant to Teskooano’s MCP server and ask it to create, edit, analyse or simulate a system. What it saves shows up in Your systems.

Saved systems are private: only you can open them.

What you can do with a saved system

Each system on Your systems shows its version, how many bodies it has, when it changed, and where it was copied from. Its buttons:

  • Open opens it in the simulator. Back to all systems in the simulator brings you back here.
  • Download saves its file to your device.
  • Delete removes it and all its versions, after asking you to confirm.

Versions

Every change to a saved system keeps the version before it. Open Versions under a system to see each one, with its date and body count:

  • Download any version as a file.
  • Restore brings an earlier version back as a new latest version, so nothing is lost.

Catalogue systems have versions too, listed on their pages, as I correct and improve them.

Copies that follow their original

When the catalogue system you copied gets a new version, Your systems says so: The original is at version 5. Press Update to it to replace your copy with the new version. Your copy keeps its earlier versions, so you can restore your own changes if you want them back.

Your data

Data and Privacy shows everything Teskooano keeps about you. From there you can:

  • Get a copy: everything, including your saved systems, as one JSON file.
  • Delete your account: your account, sign-ins and saved systems, for good.

See the privacy notice for the details.

Limits

Each system can be up to 1 MB, and every account can save up to 100 systems today. The plans set how many systems, versions and how much storage each plan keeps, as those limits go live.
