Frequently Asked Questions

Still have questions? Reach out on X.

How do I install X Remark?+

Click "Add to Chrome" and install it from the Chrome Web Store. Once installed, visit any X (Twitter) profile and you'll see the Remark panel appear on the page.

Are my notes visible to other people?+

No. Your notes are private and visible only to you. They are stored locally on your device by default, and only synced to our server if you choose to sign in with X to enable cloud sync.

What's the difference between Free, Pro, and Advanced?+

Free keeps everything local on your browser. Pro unlocks cloud sync with a one-time lifetime purchase, while Advanced is the premium lifetime tier for multi-device sync plus the higher-end features we ship later.

What browsers are supported?+

Currently Chrome and Chromium-based browsers like Edge, Brave, and Arc. Firefox support is on the roadmap.

What happens to my data if I stop using the extension?+

Your local data stays on your device unless you manually delete it. If you signed in for cloud sync, you can request full data deletion by contacting us.

How do I contact you?+

You can reach us on X or by email. Links are in the footer below.
