I bookmark things on Instagram, TikTok, X and YouTube and they're scattered everywhere. Is there one app for all of them?

Each platform keeps its saves in its own tab, with its own search or none at all. Nemos sits outside them. From any post, tap Share, choose Nemos, and the link arrives with a preview next to everything else you saved.

The important limit is that Nemos only holds what you send to it. It has no connection that pulls in your Instagram Saved tab, your TikTok favorites or your X bookmarks, so old saves need to be shared across one at a time. Most people start with new saves and move only the old ones they still care about.

Once a link is in, you can add a note about why it mattered, drop it in a folder and attach a reminder. One search then covers those links plus screenshots, notes and voice transcripts.

When something else fits better: if you only use one platform and rarely look back, its built-in saved tab is fine. For a video file you can keep, Nemos is not the tool, because it stores the link and preview.
