Social & communities
Threads come in with their replies, not just the first post — as text, not a screenshot of the first tweet. A saved thread is searchable next to the articles, videos, and notes it relates to, and readable by your own AI over MCP.

How do I save a thread?
Section titled “How do I save a thread?”From the Chrome extension (every site in the table):
- Open the post or thread in Chrome, signed in as usual.
- Open Sensefold from the Chrome toolbar and choose Capture this page. The first time you capture on a site, Chrome asks for access to that site.
- Review the preview — the extracted text, an AI summary, and suggested tags. The preview is free; no credits are spent until you save.
- Choose Save.
From a link — share the post from any app through the iOS share sheet, or paste its URL into the web app. Sensefold visits the link for you.
Which path should I use?
Section titled “Which path should I use?”- Chrome extension — a thread-aware extractor for X, Reddit, LinkedIn, Threads, Bluesky, and Hacker News, tuned for Mastodon too. It reads the page as you see it, signed in, and keeps the post plus the replies rendered on the page, in order. It is the only path for LinkedIn and for anything you can see only when signed in.
- Share a link — tuned for X and Reddit: an X link saves that one post, and a Reddit link saves the post with its comment thread. Threads, Bluesky, Hacker News, and Mastodon links are captured as readable pages through general capture. Sensefold visits the link as a signed-out visitor, so it sees what a signed-out visitor sees.
On your phone the link path is the only one; at a desktop, the extension gives the thread-aware result on every listed site.
What a save looks like
Section titled “What a save looks like”Each thread becomes one Markdown item with:
- The post and its replies, in order — for Hacker News, the story with its comments; for Mastodon, from any instance.
- Images, for X posts. Videos inside posts are not transcribed (see below).
- The original link, kept for attribution.
- A summary and tags, generated on save.
The full text is indexed, so search matches a phrase from a reply deep in the thread, not only the opening post.
Can I save a Twitter (X) thread?
Section titled “Can I save a Twitter (X) thread?”Yes, with the Chrome extension: open the thread and capture it, and the post comes in with the replies shown on the page. A shared X link saves only the one post it points to. Text and images are captured; videos inside posts are not transcribed yet.
Does it save Reddit comments?
Section titled “Does it save Reddit comments?”Yes. A Reddit save is the post with its comment thread, from the extension or from a shared link.
Why can’t I share a LinkedIn link?
Section titled “Why can’t I share a LinkedIn link?”LinkedIn posts are behind your login. Sensefold visits shared links as a signed-out visitor, so the link path cannot reach them — the table marks it N/A. Capture LinkedIn posts from your browser with the Chrome extension.
What is not supported yet
Section titled “What is not supported yet”- Instagram and Xiaohongshu (RED) — not supported on either path.
- Videos inside X posts are not transcribed; the post’s text and images are captured. Video transcripts are a YouTube feature.
If you rely on one of these, tell us: support@sensefold.app.
Troubleshooting
Section titled “Troubleshooting”- Replies are missing. The extension keeps the replies rendered on the page, so open or load the replies you want before you capture. Through the link path, Threads, Bluesky, Hacker News, and Mastodon get general capture, not the thread-aware one — use the extension for those.
- A shared link saved a login wall. The page needs you signed in. Capture it from your browser with the extension instead.
- The post is already in your library. Saving the same page again does not create a duplicate; the extension and the iOS app both tell you it is already saved.
After saving
Section titled “After saving”- Highlight and comment — turn the extension’s highlighter on for a site to highlight and quote-comment on saved threads; comments work on the web app and iOS too. See comments and highlights.
- Credits — saving is free; the summary and tags spend credits. With zero credits a shared link is kept as the URL alone, and the thread text is not fetched until you process it, so a post can change or disappear in the meantime.
- Your AI — connect Claude, ChatGPT, or any MCP client and it can search the threads you saved and cite each one by its library link. Start with Sensefold for agents.
- Export — every thread leaves with you in the Markdown ZIP export.
