## When to use it

Use Review demonstrations when it is exposed or the Mac has retained captures. This is review of existing simulation evidence, not permission to begin capture, physical teaching or training.

## Physical recordings are a separate path

This screen reviews **simulation recordings** and their retained numerical evidence. It does not list, review or export recordings from a physical arm. Use [physical setup and control](/guide/setup/physical-robot) for the hardware procedure, and read [tools and data formats](/guide/setup/robotics-tools-and-data) for supported export formats and current physical recording limits. Reading either guide does not start capture or grant permission to move an arm.

## Steps

1. Connect to the owning Mac and open Review demonstrations. Choose a retained capture and inspect its recorded samples, missing channels and outcome.
2. Add a label or retain annotation if useful, then choose Save review on Mac. These annotations are separate from the original outcome.
3. If dataset selection is exposed, select an inclusive sample range and its training, validation or test split. Add it to the selection.
4. Back in Demonstrations, review the complete selection and recorded cadence. Acknowledge data permission and choose Save selection on Mac.

## What to expect

The Mac retains your review or exact private dataset selection for its existing exporter. Selection does not convert data, upload it or train a model. Historical review can remain available after new dataset selection is disabled.

## If something goes wrong

- This guide works offline, but demonstration evidence is fetched from its Mac. Reconnect to inspect or save a review.
- Missing observations or actions remain missing. Do not label a phone trace as useful training data merely because it can be inspected.
- If captures changed, required channels are missing or splits are incompatible, read the Mac’s blocker and revise the selection. Cadence must match actual observations. Saving does not invent or resample missing data.

## Reuse outside Roboty

A saved selection, a standard dataset and a shared experiment package are different things. Read [robotics tools and your data](/guide/setup/robotics-tools-and-data#what-can-travel-between-tools) for supported LeRobot formats, additional Roboty evidence and current physical recording limits. File compatibility does not establish training value, grant source rights or validate another arm.
