Screen recording in Adom Bridge

The desktop recorder HUD

Adom Bridge can record your screen to a video file (.webm). Recording is built so that it can never happen behind your back: whenever an AI records your desktop, a small recorder window (the HUD) is visible on screen the whole time.

What you see when an AI records

The recorder HUD is a small always-on-top window in the bottom-right corner of your screen. It shows:

  • the current recording status and a Start/Stop control
  • live Screen / Microphone source toggles
  • a reason line, right at the top

The reason is required. The AI must state why it is recording ("Recording the KiCad export demo you asked for", for example) before a recording can start, and that reason is displayed in the HUD for as long as the session is open. It is also saved in a small metadata file next to each clip, so you can check later why any recording was made.

Why the HUD exists

Two guarantees, by design:

  1. You can always tell recording is on. The HUD is visible and always on top for the entire session. There is no silent or hidden desktop recording mode.
  2. You can always tell who asked and why. The reason line comes from whoever started the recording. A recording request without a reason is rejected.

There is one more deliberate safeguard on the AI side: starting a desktop recording requires the AI to explicitly confirm that it wants the whole desktop and not just a browser tab. This prevents an AI from accidentally capturing everything on your screen when it only meant to record one page.

How to stop a recording

Click Stop in the HUD at any time. Your click is honored exactly like a stop request from the AI: the clip is finalized and the AI is expected to treat it as complete. Closing the recorder ends the whole session; the HUD also dismisses itself after 5 minutes of inactivity.

One HUD session can contain several short clips. The HUD stays open between clips so you keep seeing that a recording session is in progress.

Where your clips are saved and how long they are kept

  • Each clip is a single .webm video file on your machine. The AI can list them for you (with the reason each was recorded) or copy them wherever you ask.
  • Adom Bridge cleans up its recordings folder automatically so it never fills your disk: clips are kept for about 2 days, capped at 40 files and 3 GB total. Cleanup always removes the oldest files first, so a recording you just made (or one still in progress) is never touched.
  • If you want to keep a clip long-term, copy it out (or ask the AI to) soon after recording.

Desktop recording vs tab recording

Adom Bridge has two different recording features:

  • Desktop recording (this page): records everything on your monitor, with the visible HUD and the reason line described above.
  • Tab recording: records the contents of a single automated browser tab (a Puppeteer bridge feature, pup_record_start). It captures only that tab, needs no HUD (you already see the tab), and keeps recording even if the window is covered by other apps.

If an AI is recording a browser demo, it is usually using tab recording. If the HUD is on your screen, the whole desktop is being recorded, and the HUD tells you why.
