An honest comparison of X bookmark managers
We build MarkVault. Weigh everything below knowing that. To keep it useful anyway: every claim about another product comes from that product's own website, pricing page or FAQ, checked on 2026-08-20 and listed in Sources at the bottom. There is a section on what each of them does better than us, and a section on where we fall short. If something here is wrong or out of date, tell us and we will fix it — this page is only worth anything if it stays true.
The short answer
If you want the most mature product with the biggest user base, that is Twillot. If you want it on your iPhone today, that is XSaved. If you save from LinkedIn and TikTok as well as X, that is Dewey. If you want your bookmarks turned into a reading digest, that is Tweetsmash.
MarkVault is for one specific person: someone with years of X bookmarks, a lot of them in Chinese, who wants them as files on their own disk rather than in someone's product, and who would rather pay once than subscribe. If that is not you, one of the others is probably a better fit, and we would rather you find that out here than after paying us.

What each of them does better than us
Twillot
Three years of shipping, 10,000+ installs, and a Chinese-language community we have nothing comparable to. Auto-filling folders, media downloads, and a suite of free standalone tools. If you want a product with a track record, this is it.
XSaved
iOS and Mac in beta — we have no mobile story at all. Notes attached to bookmarks, passkey sign-in, opt-in sync across devices. Their own comparison page is the most honest piece of writing in this category and it set the standard for this one.
Dewey
Breadth we do not attempt: LinkedIn, Bluesky, TikTok, Threads and web bookmarks in one place, Notion sync, RSS output, public shareable collections.
Tweetsmash
A completely different job — turning saves into scheduled reading digests, with Notion and Zotero sync and an official-API import path. If you want to consume your bookmarks rather than archive them, we do not compete.
ContextBolt
An MCP endpoint that works today with Claude, Cursor and Codex, plus AI auto-tagging. We have neither yet.
Where MarkVault falls short — read this part too
- We have not launched. Target is late September 2026. Every product above is shipping today with real users. What you are reading is a promise, not a record.
- No users, no reviews, no track record. Buying at the founding price means betting on an unproven product from an unproven developer.
- Chrome only. No Firefox, no Safari, no mobile. XSaved already has iOS in beta.
- No integrations. No Notion, no Sheets, no Zotero, no RSS, no API.
- X only. If you also save on LinkedIn or Reddit, we do nothing for you.
- No MCP endpoint yet. ContextBolt has one shipping.
- Free-tier search is deliberately basic — exact substring and Latin words only. Tokenized Chinese search is the paid feature. That is a pricing decision and we would rather state it plainly than bury it.
- We depend on X's private interfaces, exactly like every product on this page. X changes them; when it does, archiving breaks until we ship a fix. Any tool claiming this risk does not exist is not being straight with you.
What none of them do
Show you the file. Every product here says your data is “in your browser” or “on your device.” None will show you a path you can open. Ours is JSONL in a folder you chose, and we put a screenshot of it on the home page.
Tokenize Chinese. Across all five sites there is not one mention of CJK segmentation or relevance ranking. Twillot has a fully translated Chinese interface, but its own in-app search help states that a space means or and that * stands for variable text — that is whitespace splitting with boolean substring matching, which does not work on a language that has no spaces.
Sell it once. The only lifetime options in this category are $225 and $198. The $29–39 band is empty.
