# Edit with chat

> Change a Clipchat edit by asking for it: adjust cuts, reframe clips and retitle videos in conversation — the preview updates the moment the plan lands.

When Clipchat is running and signed in, the Runchat agent can work on your
open recording. Use the chat panel in the Clipchat viewer, or talk to it from
Runchat itself.

Your recording never leaves your computer. The agent asks Clipchat questions
and requests short pieces of footage to look at, and Clipchat answers from the
copy on your disk.

## What you can ask for

The agent can read your whole recording, including the transcript, what it
saw on screen, the current cut and any comments you have left. From there it
can:

* move a cut, tighten a section, or remove something entirely
* rewrite titles, subtitles and captions
* change the shape of a video, or add another one in a different shape
* watch a specific stretch of footage to answer a question about it
* re-make the videos once it has finished changing things

Ask for the outcome rather than the operation:

```text theme={null}
Cut the pause between 2:10 and 2:24.
The intro drags, trim it to about ten seconds.
Find where the deploy finishes and start the second short there.
Retitle the first short to something more direct.
Make a square version of the whole thing.
```

Because the agent can watch the footage, you can ask about things it has to
see to answer, such as when a result first appeared on screen or whether a
stretch is just dead air.

## Comments

Leave comments on the timeline in the viewer as you watch — typed, or spoken
while the video plays, so one watch-through produces your whole review — then
ask the agent to work through them. Comments are part of what it reads, so a
review can be a list of notes followed by a single instruction to apply them.
You can comment on a moment, or drag a comment's end handle to mark a range,
which is the natural way to say "cut this bit". Anything you fix by hand in
the viewer (see [Review & refine](/concepts/clipchat/review)) is recorded for
the agent too, so it builds on your changes instead of undoing them.

## Rendering

A change shows up in the viewer's live preview as soon as the agent delivers
it — nothing re-renders on its own. Make the mp4 when you're happy, with the
viewer's Render button or by asking the agent to render or publish. Only the
videos actually affected are made again: leaving the widescreen cut alone
while reworking one short means just that short gets remade.

<Note>
  The agent works on whichever recording is open in the viewer. Open a different
  one to point it somewhere else.
