Sign in with X, one click, read-only, no password. Every new account gets a 14-day Pro trial with every AI feature, no card required.

Connect X

Sign in with your X account (read-only). It can never post, follow, or message on your behalf, and your X password is never involved.

Add the extension

Install the free Marksave browser extension, that's how your bookmarks come in. No X API, no per-bookmark cost.

A free browser extension reads your own X bookmarks and sends them here. No X password, no API cost, and re-importing is always safe, duplicates are skipped.

One-time backlog

Click Import in the library to get your token, install the extension and paste it in, then open your X bookmarks and hit Auto-scroll. It walks your whole backlog and syncs everything here, sorted.

Ongoing

After that, every new tweet you bookmark on X syncs automatically the moment you save it, nothing to do.

1. 1Library → Import → copy your token
2. 2Install the Marksave extension, paste the token
3. 3Open x.com/i/bookmarks and click Auto-scroll
4. 4New bookmarks then sync automatically as you save them

Every save in one fast, visual place. Media-rich saves show their image or video; text saves render as clean cards.

Library & Categories

Switch between the full masonry library and a deck of category covers.

Filters

Narrow by media type (photos, videos, text), by category, and by sub-topic.

Density

Use the density slider to set how many columns the grid shows.

Watch later

Queue videos and long threads to come back to.

Live updates

Newly imported saves appear at the top as they arrive.

marksave.app/library

Four ways back to a save, because you rarely remember the exact words.

Keyword search

Find saves by their text, author, category, or sub-topic.

Search by meaningPro

Toggle semantic search to find a save by what it meant, not the words it used.

Ask your libraryPro

Tap Ask (or press ⌘J) and ask a question, get a direct answer with the saves it's based on. Counting and “list all” questions are answered exhaustively.

FocusPro

Tell Marksave what you're working on and it resurfaces the saves that move it forward.

This weekPro

An auto-curated weekly brief of themes, buried gems, and time-capsule resurfacing. Verified email accounts can also receive it by email.

marksave.app/library

marksave.app/this-week

Marksave does the filing, but you're always in control. Manual choices are never overwritten by the AI.

Auto-categorizationPro

AI files each save into a category and a short sub-topic automatically.

Manual folders

Create your own categories and move saves into them by hand.

Recategorize

Change a save's category from its menu, or select several and bulk-move or delete them.

Re-run categorizationPro

From Settings → Organization, re-sort anything still uncategorized.

marksave.app/library

Turn any category into a private, unguessable link.

Share a category

Visitors browse a read-only view; every card links back to the original tweet on X. Revoke the link any time. Marksave points to X content, it doesn't rehost it.

Shape the whole product around what you actually do.

Your profile

Your data stays yours, read-only access, encrypted tokens, and a one-click way out.

MaintenancePro

Generate thread summaries or rebuild the search index from Settings → Organization.

Account

Export

Download everything as JSON at any time.

Delete

Remove your account, all saves, and any X tokens in one click. This can't be undone.
