You want to record a quick walkthrough of a tab, and the tool you reach for makes you sign in, sit through an OS share dialog, then uploads the result to a cloud you didn't ask for. The popular cloud recorders are built around an account and a server: you log in, the recording lands in their storage by default. SuperchargeCapture works the other way. You record straight from the browser, the file stays on your machine, and there's no account to create.

## Record a Tab With No OS Picker

There are three sources: This tab, Window, and Screen. The first one is the reason to switch. Choosing **This tab** uses Chrome's `tabCapture` API to record the active tab directly. No operating-system screen-share dialog, no scrolling through a list of windows to find the right one, no extra click before you can start. Window and Screen capture are there when you need them, but for the most common job, recording something happening in the browser, you go from "I want to record this" to recording in a single click.

That zero-picker path is friction every recorder built on `getDisplayMedia` forces on you, every time. Removing it sounds small until you've recorded twenty clips in a day.

## Audio You Can Trust Before You Hit Record

Bad audio ruins a recording, and you usually discover it after you've already finished talking. SuperchargeCapture puts the answer in front of you first:

- **Microphone** toggle with a device picker, so you choose the right input
- A **live level meter** that moves as you speak — visual proof the mic is actually capturing
- **System audio** toggle, captured independently, for recording what the tab itself is playing
- A **countdown** of off, 3, or 5 seconds, so you're ready when recording starts

The level meter is the quiet hero here. The classic silent mic-fail, where you record a perfect demo only to find there's no sound, can't happen when you watch your voice register before you begin.

## Crash-Safe by Design

Many recorders buffer the whole video in memory and write the file only when you press stop. If the tab crashes, the browser runs out of memory, or you close the wrong window, the entire recording is gone. SuperchargeCapture writes to the browser's Origin Private File System in one-second chunks the whole time it's recording. Kill the tab mid-take, suffer a crash, or lose power, then reopen the extension and the footage is recovered from the chunks already on disk. A recorder that only holds the file in memory loses everything in the same situation.

## How It Compares

| | SuperchargeCapture | Typical cloud recorder |
|---|---|---|
| Tab recording | Direct, no OS picker | OS share dialog every time |
| Account required | No | Usually yes |
| Time cap | None | Often capped on free tier |
| Watermark | None | Common on free tier |
| Where footage lives | Your device | Their cloud |
| Mic level meter | Live, before recording | Rare |
| Crash recovery | Chunked local recovery | Usually total loss |

## Privacy

Recording is local by default — nothing leaves your device. The extension doesn't inject anything into pages until you start a capture, has no always-on content script, and runs zero telemetry. The only way a recording goes anywhere is the optional Share to Drive button, which uploads to your own Google Drive, only when you click it, and never through any SuperchargeBrowser server.
