# Find your way around a project
> Every part of a Studio app project: the chat and its @, # and / menus, the Script panel that edits video like a document, Media, Captions, Inspirations and Layers.
A project has three columns: the chat with your agent on the left, the preview in the middle, and panels on the
right. The timeline opens under the preview with **Show timeline**.
## The chat box: @, # and /
Three keys open menus right where you type.
**`@` adds something to your message.** The menu groups everything the agent can use: **Media** you added,
**Scenes & brand kit**, **Inspirations** (moments from real videos), **Captions** styles, **Voices**, other
**Projects**, **Tools**, or **Add files from your Mac**. Press **Tab** to jump between groups. Whatever you pick shows as a chip
above your words, so the agent knows exactly which file or style you mean.
**`#` picks a tool** for this request: **Storyboard**, **Brand kit**, **HeyGen Voice 1**, **Remove background**,
**HeyGen Video 1**, **Reference video** or **Create assets** (some accounts also see **Podcast edit** and **Computer
use**). Use it when
you want a specific job done the specific way ("#Remove background on the presenter, then put the title behind her").
The HeyGen ones bill your HeyGen plan when it covers them, otherwise the HeyGen API key in **Settings**.
**`/` runs a command or turns on a skill.** **/clear** starts a fresh chat (earlier messages stay above) and
in Claude Code, **/compact** shortens a long one. Below them are ready-made video formats (founder take, AI breakdown reel, cards
behind you, behind-head captions and more) and any skills you have installed: picking one turns it on for the project.
The chat header shows which agent, model and effort the next request uses (click to change), and **Skills** lists
what the agent can use: HyperFrames' own (always on), **Talking-head formats** and **Video workflows** that work only
when picked, and **Your skills** from Claude Code or Codex.
## Script: edit the video like a document
Open **Script** at the top of the right panel (on some accounts it opens from a clip's menu instead). Every word
spoken in your video appears as text. The audio is sent to HeyGen to transcribe it, so this needs your HeyGen sign-in
on a plan that includes it, or a HeyGen API key in **Settings**.
Select words (click the first, Shift-click the last), then choose **Cut** or press ⌫. The words stay in
the script, struck through, and the cut waits under **Pending video edits** above the chat box with anything else you
staged. Choose **Send 1 edit** (the count grows as you stage more) and the agent applies them all; the video gets shorter once it's done. To drop a
cut before sending, delete its row in **Pending video edits**. To bring back words already cut, select them, choose
**Restore**, and send that too.
With words selected, the bar offers:
* **Comment**: a note on those words for the agent.
* **Cut** (or **Restore** on cut words).
* **Fix words**: correct what the transcript heard. The audio stays the same.
* **Add**: a **Zoom in**, a **B-roll shot** or a **Title card** on those words.
* **Make clip** (podcast projects): cut the words into a vertical clip of their own.
* **Ask**: ask your agent about those words.
When the agent spots filler or repeated takes, the top of the script shows how many cuts it suggests and how much
shorter they'd make the video, with **Keep all** and **Cut all**. Click a suggested cut to see why, and keep or cut
just that one.
## Media, Captions, Inspirations, Layers
The row of icons at the top of the right panel, **All files**, **Captions**, **Inspirations**, **Layers** (and
**Reviews** where review is on), switches what the panel shows:
**Captions:** 91 caption styles. Click one to use it in the chat, then say where it goes.
**Inspirations:** moments from real videos (motion graphics, A-roll cuts, mobile ads, shaders), with ideas for whatever you selected.
**Layers:** every element in the video, top to bottom; pick one to select it in the preview.
**Media** lists the project's files by folder. Add one to the chat to talk about it ("use this as the background"),
and use the plus button to bring in files from your Mac.
## Framey
Framey, the small green character by the preview, shows what your agent is doing and tells you when a video is ready
or needs you. Change how it looks in **Settings** > **Framey**.
## The preview tools
Under the preview: **Select** to click any element (right-click it for **Ask Framey**, layer order, **Cut out object
here** on footage), **Draw** to circle what should change, and **Comment** to leave a note at a moment. Changes stack
up and go to the agent together; see [edit a video with the agent](https://hyperframes.heygen.com/studio-app/edit-with-the-agent.md).
