How to save highlights from X (Twitter) in one library
By Nico, Founder of Becoming · Published
Some of the best sentences you read in a year are posts on X: a founder compressing a decade into a line, a researcher explaining a paper in plain words, a writer saying the thing you had been circling. You bookmark it, and months later it is one row in a long private list you rarely open, far from the book highlights it belongs next to. To save highlights from X properly, the posts have to leave that list.
This guide covers what X gives you natively for saving posts, where those tools stop, and how to move bookmarks and likes into a highlight library. The second half describes Becoming’s X integration, which is our product, as its help center documents it.
What X offers natively
X gives you bookmarks, bookmark folders on X Premium, likes and a data archive. Each of them keeps posts inside X.
Bookmarks
X’s help center describes bookmarks as a way to save posts in a timeline for quick access at any time, and states that they are private: only you can see them, from your own account. You add one from the bookmark icon on the post and find them all under Bookmarks in the navigation menu.
For “I’ll read this tonight,” bookmarks are enough. For “I want to keep this idea,” they have three limits:
- One list. By default every bookmark lands in a single timeline. X’s help page describes no tags, notes or grouping by author.
- They stay inside X. A bookmark does not sit next to your Kindle highlights, your saved articles or anything else you read.
- Nothing brings them back. X’s help pages describe no review or resurfacing for bookmarks. You see one again when you scroll for it.
Bookmark folders (X Premium)
Folders fix the first limit. X’s help pages list bookmark folders among the X Premium features: from a post, you tap the bookmark icon and add it to a folder, or you create folders from the Bookmarks page. Every bookmark also stays in the All Bookmarks folder, and removing one from a folder doesn’t delete it from your account.
Folders are manual filing, one post at a time, behind a subscription. They leave the other two limits where they were.
Likes
Many people use likes as a lighter bookmark. They work for that, with the same ceiling: a list inside X, apart from everything else you read.
Your X data archive
X lets you request an archive of your account data. According to its help center, you ask for it from your account settings under “Download an archive of your data,” confirm your password, and receive an email when a .zip file is ready. The page lists contents such as your profile information, posts, direct messages, media and your lists of followers and following.
An archive is a backup, delivered once, as files. It is worth having, but it is not a place to search ideas, tag them or see them again, so it doesn’t answer this article’s question.
Copy and paste
The fallback everyone uses at some point: copy the text into a notes app with the link. It works for a handful of posts, not for hundreds of bookmarks, and it depends on filing each one by hand.
What a better setup looks like
Treating posts as highlights needs five properties:
- Bulk import. The backlog of bookmarks and likes comes across without handling each post.
- Organized by who said it. On X the author is the source, the way a book is the source of a Kindle highlight.
- Same library as everything else. A post about focus should turn up in the same search as the passage about focus you marked in a book.
- Resurfacing. Saved posts come back to you without you scrolling for them.
- No password sharing. Whatever reads your bookmarks should never hold your X credentials.
How to save highlights from X with Becoming
Becoming is a highlight manager: it imports highlights from Kindle, Readwise, Goodreads, Apple Books, Kobo, PDFs, web articles and YouTube into one searchable library, resurfaces a few in a Daily Review, and can turn them into four-week Themes with short daily Practices. X is one of its sources, and posts arrive grouped by author: each account you saved from becomes a source in your library, and each post a highlight on it.
Save a single post
No extension is needed. Becoming reads the post from its public address.
- From the X app: tap Share on a post and choose Becoming.
- In the Becoming app: open Integrations, then X (Twitter), and paste the post’s address under “Or save one post.”
- In the web app: open Integrations, then Save a link, and paste the address. The same field takes an article or an X post.
- On desktop, in Chrome: with the post open, click the Becoming extension’s toolbar icon. If you select text in the post first, that selection is saved as the highlight.
The post has to be public. One from a protected account can’t be read from a link.
Import your bookmarks and likes
Two routes: the app reads both lists in a single pass; the extension reads whichever page you are on.
In the Becoming app:
- Open Integrations, then X (Twitter), and choose Sync bookmarks and likes.
- Sign in to X on X’s own page, which opens in a window of its own. Becoming never sees your password, and the session stays in that window.
- Leave the screen open while it runs. It reads your bookmarks first, then your likes, saving as it scrolls and counting posts as they land.
You can stop early, keep everything already read, and run it again later to top up. If it only got through your bookmarks, it says so.
On desktop, with the Chrome extension:
- Install the Becoming Chrome extension and sign in to the Becoming web app.
- Signed in to X, open your bookmarks page or your own likes page.
- A Becoming pill sits in the bottom-right corner. Click it to open its panel and choose Import bookmarks to Becoming (or Import likes to Becoming).
- Leave the tab open while it scrolls. Stop ends the run early and keeps what was read.
The extension imports one timeline per run, so to bring in both you run it once on each page. It only works on your own likes.
The panel also has an opt-in Keep this in sync automatically checkbox. With it on, opening your bookmarks or likes page starts the import after a short countdown you can cancel, as long as more than a day has passed since that page’s last run. Nothing runs while your browser is closed; the visit is what starts it.
What Becoming can and can’t see
As the help center explains, X has no usable import API for bookmarks, so both routes read what is already on screen: the app in a window on x.com, the extension on the page you are looking at.
- Becoming never sees your X password.
- The extension only runs on your bookmarks and likes pages. It can’t post on your behalf or change anything about your account.
- Nothing reads in the background. The app needs its sync screen open, and the extension needs the tab open.
Details worth knowing
- They stay. Un-bookmarking or unliking a post on X doesn’t remove it from Becoming.
- No duplicates. Re-running a sync only adds what is new.
- Posts don’t spend AI credits. A post’s text is the highlight, so no model has to read it. That holds for bookmarks, likes and single posts.
- There is a daily cap on how many posts a sync brings in, higher on a paid plan than on the trial. Past it, the run still finishes: the newest posts land and the rest arrive on your next sync.
- Threads aren’t expanded. A saved post comes in on its own, without the conversation around it.
- Long posts arrive in full, as a single highlight.
- X may pause a fast read. If you see “X paused the import,” everything already read is kept. Wait a few minutes and run it again.
The full walkthrough is in the Becoming help center.
After the import
Once posts are highlights, they behave like the rest of your library: they show up in search, including search by meaning, next to passages from books and articles, and they come back in the Daily Review. On The Academy, they count among the highlights Becoming reads when it proposes a Theme, which is how a post you bookmarked in January can end up as a two-minute practice in June. The reasoning behind that step is in how to apply what you read.
The same library takes video: see how to save highlights from YouTube videos. If you are still choosing a highlight manager, the roundup of the best Readwise alternatives compares the live options, including which ones list X as a source.
Becoming’s X import is part of The Library, at $4.99 a month or $49.99 a year, with a 7-day free trial. See the pricing section.
