Reversible AI work
Experiment without losing the path back.
Chat checkpoints preserve AI-touched file contents and diff state so you can move backward or forward through an agent session.
01File snapshots
02Backward restore
03Forward restore
More than undo
Restore the set of files changed by the AI rather than relying on a single editor buffer history.
Current boundary
Checkpoints focus on AI-touched files. They are not a replacement for Git, backups, or full environment snapshots.
AI coding, under your control
Build with your tools, models, and rules.
El-cro puts you in control of your models, keys, and data.
