SomedayX
X (Twitter) bookmark managers compared: SomedayX vs Dewey vs Tweetsmash vs Twillot
Short answer: for free, private search by meaning on a Mac, including text inside screenshots, use SomedayX; everything stays on your computer. If you save from many social networks or need Windows, Dewey covers 10 platforms. For AI digests and Notion exports, Tweetsmash. For a cheap browser-only archive that also stays local, Twillot. X's own bookmark search is fine if you remember exact words.

SomedayX
A free, open-source Mac menu-bar app (made by the author of this page). Double-tap Option, type what you remember, and it finds the post by meaning, including text inside screenshots and the full text of X Articles, across bookmarks and likes. Search runs on your Mac with Google's EmbeddingGemma model via llama.cpp, and Apple Vision for OCR; there's no account and no server.
Good for: people with thousands of saves who want to find things again, privately, for free. Not for: Windows or Linux users, other social networks, or anyone who doesn't want a short terminal install. It reads X through your own logged-in session, which is unofficial.
X's built-in bookmark search
Free on the web and iPhone: a search bar at the top of Bookmarks. It matches exact words in the post's text, so it misses posts you remember by topic, anything inside an image, and your likes. Folders need a paid X subscription.
Good for: quick lookups when you remember a distinctive word.
Dewey
A cloud bookmark manager with a Chrome extension and web dashboard that syncs saves from X and about ten other networks, with tags, folders, notes, AI tagging and exports. The free plan syncs manually; automatic sync needs Pro.
Good for: people who save across many platforms and want one organised library. Consider: your bookmarks live on Dewey's servers, and search is keyword-based.
Tweetsmash
An X-only bookmark tool with semantic search, an AI chat over your saves, digests, and exports to Notion, Google Sheets and Zotero, plus an API and MCP server. Its Chrome extension imports your full history.
Good for: people who want AI summaries and digests and push bookmarks into other tools. Consider: data is stored on Tweetsmash's service, and full-text search is a paid feature.
Twillot
A Chromium extension that archives your bookmarks and likes and indexes them inside your browser, with full-text search. AI is used to sort posts into folders.
Good for: a low-cost, local archive if you work on Windows or Linux. Consider: keyword search only; the free plan covers 100 saved items.

FAQ
Is there a free alternative to Dewey?
Yes. SomedayX is free and open source (MIT) and searches your X bookmarks and likes by meaning on your Mac. It covers X only, while Dewey covers about ten networks. Twillot's free plan covers up to 100 saved items.
Which X bookmark manager doesn't upload my data?
SomedayX keeps everything on your Mac, including the AI search model. Twillot keeps its archive in your browser. Dewey and Tweetsmash store your bookmarks on their servers.
Which tool can search text inside images I bookmarked?
SomedayX reads text in saved images with Apple's on-device OCR. None of the other tools here say they do.
What's the difference between semantic search and keyword search?
Keyword search finds posts containing the exact words you type. Semantic search finds posts about what you mean, so "pricing advice" also finds "we doubled our price and churn went down".
