## Allow screen recording

macOS asks once, the first time you record. Turn Bingsu on in System Settings, Privacy & Security, Screen & System Audio Recording, then reopen Bingsu.

The camera and the microphone are separate questions. macOS asks for each only when you first use it. Bingsu never turns either on by itself.

## Record your screen

1. Click the Bingsu icon in the menu bar, or press ⌥⇧⌘R from anywhere.
2. Pick what to record: a screen, a window, an app or an area.
3. Press Record. Press Stop and Save when you are done.

Every file is checked after it is saved: its length, its picture, its sound tracks, silence, and whether a window closed. A problem shows as a warning on the recording.

Files go to `~/Movies/Bingsu`. Change the folder in Settings.

## Pick a window, an app or an area

- **A window** keeps recording when other windows cover it, and takes only that app's sound.
- **An app** records all of its windows.
- **An area** records a fixed part of a screen. Drag to draw it.
- **A screen** records everything on that display.

A minimized window sends no picture. The recording repeats its last frame until you bring the window back.

A minimized window sends no picture. The recording repeats its last frame until you bring the window back.

## Sound and microphones

A window or app recording takes that app's sound and nothing else. A screen recording takes the Mac's sound.

Add any number of microphones. Each shows a live level, gets its own track in the file, and goes into one mixed track that every player plays. If a microphone is unplugged, its track stays silent until you plug it back in, and the recording goes on.

## Your camera and call guests

Choose a camera in the panel's Camera row. It sits over your recording as a bubble, and it is also saved as its own video track.

- Drag the bubble anywhere. Drag its corner to resize it.
- Make it a circle, a rounded square or wide, and mirror it from its toolbar.
- Right-click it to turn the camera off or hide it.

In Zoom, Meet, Teams, FaceTime, Slack, Discord, Webex or WhatsApp, Bingsu finds the people in the call window and adds each as a bubble, up to five faces. It can follow whoever speaks, or one person. Each guest's voice comes from the call app on its own track. Finding faces runs on your Mac; nothing about a face leaves it or is kept.

## Pause, stop and the lock screen

- Pause and resume leave no gap in the file.
- Give a recording a length and it stops on the exact second.
- When the screen locks, Bingsu pauses and goes on when you sign back in. Change this in Settings.
- If the Mac crashes, Bingsu writes files in two-second pieces and recovers the half-written file the next time it opens.

## Trim, cut and crop

Open a recording in the editor.

1. Drag the handles to trim the start and the end.
2. To cut a part out, mark it with I and O, then press X. ⌘Z undoes.
3. Crop to 16:9, 9:16, 1:1 or 4:3.
4. Save a copy as HEVC, H.264, ProRes, a GIF or sound only.

The original is never changed. Each edit saves a new file next to it, named "(edited)", "(1080p)" and so on.

## Zoom and backgrounds

Focus and Frame are added when you save a copy, never baked into the original.

- **Focus** zooms in smoothly where you click and type and smooths the pointer. Every zoom shows on the timeline, where you can move, change or remove it.
- **Frame** puts a window or area on a background, with padding, rounded corners and a shadow.

## Transcript, captions and chapters

Bingsu writes a transcript with times, using Apple's on-device speech model. Nothing is uploaded and nothing costs credits. On a Mac with Apple Intelligence it also writes a title, a short summary and chapters.

- Show captions on a share page, or burn them into a copy of the video.
- Cut the video by deleting words in the transcript.
- Every language your Mac supports works. macOS downloads a language's model the first time it is used.

Turn this off in Settings, General, "Understand recordings".

## Share a page

Bingsu turns a recording into a folder that is a whole website: a player, the title, chapters, the transcript and captions. You publish it where you already host sites. We never see the page, its link or its viewers.

| Host | Publish the folder with |
| --- | --- |
| Cloudflare Pages | `npx wrangler pages deploy <folder> --project-name <name>` |
| Vercel | `npx vercel deploy <folder> --prod --yes` |
| Netlify | `npx netlify-cli deploy --dir <folder> --prod` |
| GitHub Pages | `npx gh-pages --add -d <folder> -e <name>` |
| ChatGPT Sites | Ask Codex in the ChatGPT app to publish the folder |

Preview the page on your Mac before you publish. The page offers no download of the video unless you turn it on. Anyone with the address can watch it, so keep the address to the people it is for.

## Connect an AI agent

Copy the connect prompt from [bingsustudio.com/agents](https://bingsustudio.com/agents/#connect) into your agent app: ChatGPT for Mac, Claude, Codex, Cursor, Grok Build and others. It adds Bingsu as a local MCP server, checks that it works and tells you what it can do. The same page lists the steps for each app by hand.

The first time an agent asks to record, Bingsu asks you in its own window. Settings, Agents lists every agent you allowed, with Revoke.

## Ask an agent to record

Ask in your own words. For example:

- "Record this window while you run the tests, with sound off. When you are done, stop, check the file and tell me where it is."
- "Record the Settings window for 20 seconds, then make a share page from it and give me the folder."
- "Record my browser for 30 seconds at 60 fps, then save a GIF copy under 10 MB."

An agent checks the picture first with `bingsu_screenshot`, records with `bingsu_start`, and trusts a file only when its check says `ok`. Its recording shows in your menu bar with its name, and you can stop it at any time.

## What an agent can do

| Tool | What it does |
| --- | --- |
| `bingsu_sources` | Lists displays, windows, apps, microphones and cameras, with ids |
| `bingsu_screenshot` | The exact picture a recording of a source would show |
| `bingsu_start` | Records a source; with `seconds` and `wait`, returns the saved, checked file |
| `bingsu_wait`, `bingsu_stop`, `bingsu_pause` | Waits for, stops or pauses the agent's own recording |
| `bingsu_status` | What is recording, room for more, free disk space |
| `bingsu_recordings`, `bingsu_verify` | Recent recordings and their checks; checks a file again |
| `bingsu_export` | A trimmed, cut, cropped or converted copy; never overwrites |
| `bingsu_understand` | Transcript, title, summary and chapters, made on the Mac |
| `bingsu_share_page` | A website folder for a recording, ready to publish |
| `bingsu_mark`, `bingsu_script`, `bingsu_presenter` | Named steps, a narration script, and a voice or presenter clip |

Every error has a stable `error` code, a `message` and a `fix`.

## Let several agents record at once

- Each agent records, stops and pauses only its own recordings. You see all of them in the menu bar and can stop any.
- An agent's window and app recordings take that app's sound without playing it on your speakers.
- Agents drive browsers with their own tools, never your pointer or keyboard.
- Bingsu never lowers quality to fit one more recording. When the encoders are full, an agent hears `busy` before it starts, or waits in line with `queue: true`.
- An agent that needs a whole screen can make its own virtual display with `bingsu display add`.

## Camera and microphones for agents

Agents can't use the camera or microphones until you turn on "Can use the camera and microphones" in Settings, Agents. It is off at first. Without it, an agent that asks for one gets `devices_off`, and a recording never turns one on by itself.

## Use the command line

The `bingsu` command does what the MCP tools do, with the same JSON answers.

```sh
bingsu record "Safari" --for 30s --json
bingsu edit <id> --start 3.5 --end 1:20 --format gif --max-mb 10
bingsu share-page <id> --title "Design review, new onboarding"
```

Exit code 3 means the file was saved but its check found a problem. Set `BINGSU_SESSION` to a value unique to your script, so its recordings stay its own.

## Updates

Bingsu checks for updates once a day by downloading a small file that lists the latest version. The request tells the server your version and nothing else. Each update is signed, and Bingsu installs only an update whose signature matches. Turn the check off in Settings. With Homebrew, run `brew upgrade`.

## Privacy

Recordings, transcripts and settings stay on your Mac. There is no account, no analytics, no crash reporting and no telemetry. An agent you connect sees what Bingsu returns to it, such as file paths, screenshots and transcripts, and its app may send that to its own servers under its own terms. Read the [privacy policy](https://bingsustudio.com/privacy/).
