10 Practical, In‑Browser Comet AI Use Cases You Can Try Today

Calm, useful ways to tidy your day – no connectors, no background access, just the tabs you already have open.

Modern AI tools can be powerful without intruding. If your working day lives in the browser, Comet can sit quietly at your side and help with the fiddly bits – drafting, tidying, and sense‑making while you stay in control.

Why Comet?

Everything below works right in your browser tabs (Gmail/Outlook, Calendar, Squarespace, Sheets/Docs, LinkedIn, vendor sites). No plug-ins, no integrations.

Privacy, Really First

Comet is designed from the ground up to protect your information. Here’s how it’s different:

• In-browser only: Comet acts only on the sites you have open. It doesn’t run in the background, doesn’t scan your desktop, and never rummages through local files or cloud drives unless you explicitly ask.

• No integrations needed: There are no backdoor connectors or syncs. Comet simply uses what’s visible to you.

• Your data, your control: Browsing history and page content never leave your device unless you trigger an AI help request. Even then, only the minimum required data is securely processed - nothing is stored or sold.

• You can erase anything, anytime: Clear your history, cookies, or AI prompts with one click.

• Transparency and consent: If a workflow does need extra access (like helping draft a Gmail reply from your inbox), you choose to grant it; no silent permissions.

• Recommended safety habits:

  • Keep sensitive info (IDs, private data) out of your AI requests.

  • For group emails, always use BCC.

  • Review your Comet and Google/Microsoft permissions monthly - revoke anything you don’t use.

Incognito/private windows? All the same controls apply and most local storage is automatically off.

Comet is built for privacy-conscious users - but, as with any AI tool, it’s wise to keep a regular security routine for total peace of mind.​

Extending Privacy to Security: Spotting Hidden AI Risks

While browser-first AI, like Comet, gives you unmatched control and privacy by acting only on open tabs and requiring your explicit consent, there’s another emerging risk: prompt injection. This technique allows attackers to hide unwanted instructions in emails or calendar events, causing less-secure agents to leak or manipulate data without your knowledge. Comet’s layered approach, including live screening for hidden prompts and always seeking your confirmation, directly addresses this, keeping both your privacy and security in focus.
