Unroll any X thread.
Save the whole chain.
ContextBolt walks the thread when you bookmark the head, captures every tweet, and lets you search the full chain by meaning. Free, no paywall, no thread-of-the-day limit.
The problem
Why this is harder than it should be
X bookmarks save a single tweet. ThreadReader and Unroll work but live behind paywalls and break when authors delete. Screenshots stop you searching. You bookmark a thread, the author edits it, and the thing you saved is no longer the thing that was there.
How ContextBolt does it
Three steps. All automatic.
Install for Chrome (one click)
Add the free ContextBolt extension. Works in Chrome, Brave, Arc, and Edge. No account, no paywall.
Bookmark the head tweet
ContextBolt walks the chain automatically. Replies, quote tweets, media. The whole thread is captured as a single entry, even if the author deletes it later.
Search the thread by meaning
Find threads by what they were about. 'That hiring rant from last month' surfaces the right thread, even if it was 12 tweets long and you cannot remember the words.
MCP integration
Searchable from inside your AI agent
Pro users get a personal MCP endpoint. One line of config and Claude, Cursor, or Windsurf can search your bookmarks during a conversation.

Why ContextBolt
Built for retrieval, not just storage
Whole thread, not just the head
Most tools save the tweet you clicked on. ContextBolt walks the full chain so a search hits content from tweet 7 of 12, not just the opener.
Survives deletion and edits
ContextBolt captures the thread the moment you bookmark it. If the author deletes or edits later, your saved version is the one that was actually there.
No paywall, no daily limit
ThreadReader caps free users. Unroll asks for a sub. ContextBolt's free tier covers up to 150 bookmarks including threads, with no per-day cap.

FAQ
Common questions
Does X let you bookmark an entire thread?
No. X's bookmark feature saves the single tweet you click the icon on. To capture the full thread, you either rely on the head tweet not getting deleted, use a thread unroller like ThreadReader, or use a bookmark manager that walks the chain automatically. ContextBolt does the third by default.
What is the best Twitter thread unroller in 2026?
For one-off reading, ThreadReader App is still the fastest tool to view a thread on a clean page. For a permanent searchable library, ContextBolt captures threads as part of your bookmark workflow with no paywall and AI-powered semantic search across the full chain.
How does ContextBolt save a Twitter thread as PDF?
The dashboard has a one-click export to PDF, Markdown, or JSON for any thread in your library. The PDF preserves the order, author, timestamps, and any media URLs from the original chain.
What happens if the author deletes the thread later?
Your saved version stays intact. ContextBolt captures the full thread to your library at bookmark time, so a deletion on X does not remove the content from your library. The original tweet URLs are preserved so you can see exactly what was deleted.
Is there a limit on how long a thread can be?
No practical limit. ContextBolt has captured threads of 50+ tweets without issue. The capture runs in a service worker so it does not slow the page you are reading on.
Will it work on quote tweets and replies, or only top-level threads?
It walks the reply chain on any thread you bookmark, including quote-tweet chains. If a tweet has multiple replies forming a chain, the chain is captured. Standalone replies that are not part of a thread are saved as individual bookmarks.
