Plate ∗.for researchers

xmark for researchers.

Your X bookmarks are a literature review waiting to happen.

You save threads about your field on X. xmark turns the pile into a searchable corpus — semantic search by topic, chat with citations, export to Markdown for your notes app.

Questions that work

"What did I save in the last year about reinforcement learning from human feedback?"

— what happens: Returns the threads, grouped by angle, with citation links back to each tweet.

"Summarize the disagreements in the threads I saved about consciousness."

— what happens: Claude reads the relevant bookmarks and steelmans each side with citations.

"Find the post that introduced me to [author] — I think it was a quote tweet."

— what happens: Semantic + structural search picks up quoted-tweet context that keyword misses.

A workflow that works

  1. 01.Sync xmark once a week.
  2. 02.Ask topic questions when starting a new doc or memo.
  3. 03.Export results as Markdown into Obsidian / Notion / Logseq.
  4. 04.Cite the original tweets in your prose, not the xmark URL.

Researchers usually hit the sync limit first — xmark is unlimited at $5/month.
