XTOC: Navigate & Clip X Articles by AriesZhou

Long X/Twitter articles are easier to follow when their structure stays visible, and worth keeping when you find them. XTOC turns article headings into a table of contents you can open from the toolbar or pin beside the article, and keeps the posts, articles and passages you save in a local library.

Read
• Jump between article sections and follow your current section while scrolling
• Pin, move, resize and collapse the table of contents

Save
• Select a passage and click "save to xtoc" to keep it with its source and surrounding context
• Save the post or article you are reading from the toolbar button
• Import your X bookmarks from X's Bookmarks page in one click; XTOC only reads what the page loads and never changes your X bookmarks

Organize and export
• Library with two views: Clips and Bookmarks
• Search, filter by tag, add tags and notes, select and delete
• Export as Obsidian-style Markdown (one note per post or article, with properties, tags and quoted clips), or export clips as JSON

Optional AI (off by default)
• Suggest up to three tags and a short summary for a bookmark using your own provider API key
• Runs only when you click it. Only that bookmark's saved text and your existing tag names are sent, directly to the provider you choose; your notes are never sent. Nothing changes until you apply the suggestion
• The key is kept for the browser session, or, if you choose, encrypted on this device. It is never synced or exported

Privacy
Clips, bookmarks, tags, notes and settings are stored locally in your browser. XTOC has no account, no telemetry and no cloud storage. Exports are created only when you request them.

Works on x.com and twitter.com. The table of contents depends on headings being present in the article. Bookmark import saves the text X shows in the list, which may be a preview of a long post.
