xi (apiproai.com) can download videos from public Facebook Groups — just copy the video link and paste it into xi like any other Facebook video.
There are many ways to save Facebook Group videos — screen recording, browser extensions, third-party apps — but most come with trade-offs. Screen recordings lose quality and capture notifications and UI elements. Third-party apps often demand your Facebook login (a real account-theft risk), show aggressive ads, or quietly upload your contacts. Browser extensions can read everything you browse.
xi avoids all of that:
On iPhone (Safari): open xi at apiproai.com, paste the link and tap Download. When the file is ready, tap the download icon in Safari's address bar, open the file, then tap the Share button and choose Save Video (or Save Image) to move it into your Photos library.
On Android (Chrome): the process is even simpler — after tapping Download on xi, the file saves straight to your Downloads folder and appears in your gallery app automatically.
On desktop: paste the link into xi, click Download, and the file lands in your browser's download folder. From there you can rename it, move it, or import it into any video editor.
"No media found" or empty result: the most common cause is a private or deleted post. Copy a fresh link directly from the Facebook app (Share → Copy Link) rather than from a screenshot or a third-party site, and try again.
Download starts but never finishes: switch to a stable Wi-Fi connection and avoid VPNs that throttle traffic. Very long videos can take a minute or two to prepare — give it time before retrying.
Button doesn't respond on iPhone: make sure you're using Safari (not the in-app browser of another app). If the page seems stuck, pull down to refresh and paste the link again.
File won't play: MP4 and MP3 from xi play in every modern player. If your gallery app can't open it, try VLC — it's free and handles everything.
No — private group videos are only served to members, and downloaders can't authenticate as you.
The post may have been deleted, or the video's own privacy is stricter than the group's.
For public groups, no — the video link alone is enough.
No — xi fetches the file server-side; there's no download notification.
