Desktop software is a program you install and run directly on your computer's operating system (Windows, macOS, or Linux), rather than inside a browser tab. You should choose it over a browser extension or web app when your task needs deeper system access, steadier performance, or offline capability — for example, real-time meeting transcription that captures audio from multiple apps. Browser extensions are lighter and install in seconds, but they live inside one browser and inherit its limits.

What "desktop software" actually means

A desktop app is installed on the machine and runs as its own process. It can:

• Read and write local files without a download/upload round trip
• Access system-level resources like the microphone, speakers, camera, and other running apps
• Keep working when the browser is closed or the network drops (depending on the app)
• Persist settings and data locally

This is different from a web app, which runs in a browser tab and depends on a live connection and browser permissions, and from a browser extension, which is a small add-on that modifies or extends one browser's behavior.

Desktop app vs. browser extension vs. web app

The practical takeaway: extensions and web apps are convenient and low-commitment; desktop apps trade a heavier install for capability and stability.

When a desktop app is the better choice

Pick desktop software when the task depends on one or more of these:

• Capturing audio from multiple sources at once — a meeting where you're on a call and taking notes. A desktop notetaker can tap system audio and the mic; a browser extension generally can't reach outside its tab.
• Real-time transcription and live summaries — Otter's Meeting Agent is described as supporting real-time transcription, live chat, automated summaries, insights, and action items. That kind of continuous processing benefits from a local process rather than a single browser tab.
• Long or resource-heavy sessions — recording and transcribing for an hour is more stable outside a tab you might accidentally close.
• Working across apps — if your workflow spans a video call app, a document, and a notes tool, a desktop app can sit across all of them.

Choose a browser extension instead when you only need to enhance one website (for example, adding a button to a specific web tool), want zero install friction, and don't need system-level access.

How to choose and install a desktop app safely

1. Confirm the task fits a desktop app. If you only need to tweak one website, an extension is lighter. If you need system audio, local files, or offline use, go desktop.
2. Check system requirements. Match the OS (Windows/macOS/Linux) and version. Download only from the vendor's official site — for Otter, that's otter.ai.
3. Review permissions before granting. A meeting/transcription app will ask for microphone (and possibly screen or system audio) access. Grant only what the task needs.
4. Install and sign in. Follow the vendor's installer. If the app requires an account, expect a login step.
5. Verify it works. Run a short test — record 30 seconds and confirm transcription or capture appears as expected.
6. Check update and pricing terms. Otter lists a pricing page at otter.ai/pricing; check it for current plan limits rather than assuming a free tier.

Troubleshooting common desktop software problems

• Install fails — confirm OS version meets requirements, free up disk space, and re-download from the official source (a corrupted installer is a common cause).
• App crashes on launch — update to the latest version, restart the machine, and check whether a security tool is blocking it.
• No audio captured — re-check microphone/system-audio permissions in OS settings, not just in the app.
• Sync or login issues — verify your network and credentials; if the app stores data locally, confirm it isn't blocked by a firewall.
• Extension works but desktop doesn't (or vice versa) — they use different permission models; a feature available in one may not exist in the other.

If your goal is AI meeting transcription with live summaries and action items, a desktop app is usually the more capable choice; if you just need a small tweak inside one website, a browser extension is the faster path.
