Structure by design.

$CHEMA is a desktop app for Windows and macOS. It designs a folder architecture for a drive or folder, shows every change it proposes, and moves things only after you approve the exact plan.

Status: in private testing. $CHEMA is not available to download yet.

Built around four rules

• LOCAL ONLYNo network, no account, no telemetry.
• NOTHING LEAVES THIS COMPUTERIt reads names, sizes and dates, never file contents.
• NEVER DELETEIt is designed never to delete your files.
• NEVER OVERWRITEIt is designed to stop rather than replace anything that already exists.

These are design goals. We are checking them on real computers and real drives in testing before anything is released.

How a run works

1. Select a target. Any folder or drive. A read-only scan changes nothing.
2. Design a Blueprint. Name folders, drag them into order; numbering follows position.
3. Preview. Every change is listed as current path to proposed path. Conflicts wait for your decision.
4. Apply. Runs exactly the plan you reviewed, and is recorded in the Ledger.
5. Undo. The latest run can be reversed.

What comes next

Private testing first, then signed installers for Windows and macOS, then a public release. Nothing is promised before it has been tested.
