The short version: No, bookmarks on X are private. Nobody can see your bookmarked posts, not your followers, not the person who wrote the post, not even someone who has your password and logs into your account from a different device (well, they could, if they're literally inside your account). What you do with a bookmark afterwards, though, can absolutely give you away.
What X says about bookmarks
X has kept the bookmarks feature deliberately quiet since it launched in 2018. There's no public bookmarks list, no API endpoint that exposes someone else's saved posts, and no setting you can toggle to "share" your bookmarks with followers. When you tap the bookmark icon under a post, that post gets added to a folder only you can open, found under your profile icon, then Bookmarks. That's it. There's no notification sent to the original poster, no icon that changes publicly, nothing in their analytics that flags it.
Compare that to likes, which used to show up in a public "Likes" tab on every profile (X quietly removed that public tab for most accounts a few years back, which tells you something about how much weight the platform now puts on privacy around user behaviour). Bookmarks never had that public tab in the first place. They were built as a private "save for later" tool from day one, closer to a Pinterest board only you can see than a public endorsement.
The one thing that can expose a bookmark
Here's where I want to be blunt, because most explainers stop at "bookmarks are private" and leave it there, which is technically true and practically incomplete. Bookmarking is invisible. What you do next is not.
- If you bookmark a post and then quote it, reply to it, or retweet it later, that action is public even though the original bookmark wasn't.
- If you're logged into X on a shared laptop or a work computer and someone else opens the browser with your session still active, they can open your Bookmarks folder directly. No hacking required, just a login you forgot to close.
- If you use a third party browser extension or a scheduling tool connected to your X account that reads your saved posts for content curation, that extension has access to your bookmarks list even though the public doesn't.
So the honest version isn't "bookmarks are 100% invisible forever." It's "bookmarks are invisible to everyone except whoever is physically inside your logged in account, and your own future behaviour with that saved post."
A worked example
Say you run a small marketing agency and you're scrolling X during your lunch break. You see a competitor's post about a pricing model you think is clever, and a prospect's post complaining about a supplier, and a post from a journalist asking for case studies for a feature. You bookmark all three, planning to come back to them that evening.
Nobody involved in any of those three posts gets a notification. The competitor has no idea you're studying their pricing. The prospect doesn't know you've flagged their complaint as a possible opening line for an outreach message. The journalist doesn't know you've saved their callout. That evening you open Bookmarks, reply to the journalist's post with a short pitch, and quietly delete your own reply an hour later because you reworded it. The reply itself was public and anyone who saw it in the moment saw it. The bookmark that got you there never was.
That's the realistic use case most people have for bookmarks: a private staging area for research, outreach ideas, or posts you want to reference in your own content later, with the actual visibility risk sitting entirely in what you post afterwards, not in the saving itself.
Why people assume bookmarks are public anyway
Three reasons this myth keeps circulating:
- People confuse bookmarks with likes, which used to be semi-public on X's old "Likes" tab, and some long-time users still remember that era.
- People confuse X bookmarks with Instagram "Saved" collections, which can be made into public collections if you choose to, unlike X's version.
- Screenshots circulate claiming to show "who bookmarked your post," almost always fake, built in a basic photo editor, because X has never shipped that feature and has no plans to, as far as any official changelog shows.
If you ever see a tool, browser extension, or Chrome plugin claiming to reveal who bookmarked a specific post, treat it as a scam or at minimum as something that's reading public engagement signals (replies, quote tweets, profile visits if you've got that data from somewhere) and repackaging them as "bookmark data." There is no legitimate way to pull that information, because X's own backend doesn't expose it through any public API.
How many posts you can bookmark
One practical detail worth knowing: X caps bookmarks at roughly 800 posts per folder, and Premium subscribers get the ability to organise bookmarks into separate folders rather than one long scrolling list. If you're using bookmarks as a genuine research tool, say for tracking competitor messaging or building a swipe file of post formats that get strong engagement, hitting that cap sneaks up faster than you'd think if you're saving ten or more posts a day. Folders are the fix, and they're private the same way the main list is.

What this means for your own strategy
If you're building an audience on X and trying to understand what works, bookmarks are a far better private research tool than most people use them for. Instead of just liking posts you admire (which, depending on your settings, might surface in places you don't expect, and which disappears into a feed you'll never find again), bookmark the ones with a hook, structure, or call to action worth studying, and build folders by type: "hooks that worked," "thread structures," "replies that got picked up." None of it is visible to anyone, so there's no reason not to be ruthless about saving anything useful, including posts from accounts you'd never publicly engage with.
It's also worth remembering that your own posts' bookmark count is visible to you in the engagement numbers under each post, even though the identities of who bookmarked them aren't. If you want to understand which of your posts people are quietly saving for later (a strong signal of genuine value, arguably stronger than a like, because someone bookmarking your post intends to act on it), that number sits in the same place as your other metrics. I've written more on where to find and how to read those figures in this breakdown of where X analytics moved and how to read them, and a deeper look at what to track in your X analytics if bookmarks are just one metric among several you're trying to make sense of.
A bookmark count that's consistently higher than your retweet count on a given post is worth paying attention to. It usually means the post is useful rather than entertaining, which, if you're trying to build authority rather than just reach, is the better signal to chase. If you want more of that reaction specifically, it overlaps heavily with what makes people retweet in the first place, which I cover in more detail in this piece on getting more retweets on X.
A note on privacy habits worth building anyway
Even though bookmarks themselves are safe, the broader lesson is to treat your X account the way you'd treat an email inbox, not a public stage. Log out of shared devices. Check which third party apps have access to your account under Settings, then Security and Account Access, then Connected Apps, and remove anything you don't recognise or no longer use. If you've ever changed your display name or your username to rebrand your account, it's worth doing that same account audit at the same time, since that's usually when people are already in their settings menu anyway and it takes two extra minutes. And if you're curious about adjacent "who can see what" questions, the same logic applies to post views, which I've covered separately in this guide to seeing who viewed your posts on X, another feature people assume is more exposed than it is.
If you're managing an X account for a business and you want someone to sit down with your settings, your analytics, and your content strategy rather than guessing at what a platform update changed this month, that's the kind of hands-on audit an AI consultant for small business can do in a single session.
Frequently asked questions
Can someone see my bookmarks if we follow each other?
No. Following someone, being followed back, or even being close friends on the platform makes no difference. Bookmarks are tied to your account's private settings, not your follower relationships, so mutual followers have exactly the same zero access as a complete stranger.
Does the person whose post I bookmark get notified?
No, X sends no notification when a post is bookmarked, unlike replies, quote tweets, and retweets, which are all visible public actions. The only number that changes is the bookmark count on the post itself, visible to everyone as a total figure but never attached to a name.
Can I tell who bookmarked my own tweet?
No. X shows you the total count of bookmarks on your own posts in your analytics, but it does not show you the identities of the accounts that bookmarked it, not even to the original poster. That data simply isn't exposed anywhere in the platform's interface or API.
Is there a limit to how many posts I can bookmark?
Yes, X caps bookmarks at around 800 posts per list, and Premium subscribers can split bookmarks into multiple folders to organise around that limit, which is worth setting up early if you're using bookmarks as a working research tool rather than an occasional save button.
