How to Save a Reddit Thread as Markdown

You found the thread. Four hundred replies, an argument in the middle of it, and somewhere in there the answer to the thing you were actually looking up. You want to ask a model about it rather than read all of it, which means getting the thread out of the browser first.

Selecting the page and pressing copy is the obvious move, and it is the one that quietly loses the thing that makes a thread a thread.

What copy and paste loses

A discussion is not a document. Its meaning lives in the shape: who said what, in reply to whom, and how much the room agreed. Copy the rendered page and you get the words with the shape stripped out.

  Depends on the workload

On the left, a reply reads as one more paragraph. On the right it still reads as a reply to the thing above it, and the model can follow who is answering whom. Same words, very different odds the answer you get back is about the right disagreement.

Half the thread is not on the page

There is a second problem, and it is the one that catches people out. Reddit does not render the whole thread. It renders the part it thinks you want and hides the rest behind "more replies" links, which you then click one at a time.

We measured this on one thread on 2026-08-19: 25 comments were on the page when it finished loading, out of 41 in the thread. Select-all could not have taken the other 16 because they were never there to select.

So a copy of the page is not a copy of the thread. It is a copy of the visible top of the thread, and nothing on screen tells you which one you are holding.

Save the whole thing instead

FileConcat Clipper is a browser side panel that reads the thread properly and hands it to you as Markdown.

1. 1

   Open the panel on the thread

   Click the toolbar icon. The panel reports what it can see, which on a Reddit thread is Clip this post. It re-reads the page whenever you navigate, so it never describes the page you came from.

2. 2

   Turn on Expand more comments if you want the deep replies

   It clicks the thread's own "more replies" links three rounds deep. On that same 41-comment thread it reached 38. It is off by default because it is slower, and the switch is in the panel's settings.

3. 3

   Clip it, then send it

   The clipping lands in the panel's cart with every author, score and level of nesting kept. Send pushes it into an open fileconcat.com tab, opening one if there is none.

One thread, or the whole subreddit

A subreddit's front page is a listing, so the panel puts a tap target on every row it has loaded. Tap the posts you want and each one is opened and read on its own, which turns a session of scrolling into a set of files rather than one flattened page of headlines.

There is one honest limit worth knowing. A post clipped from a listing carries its full body but not its comments, because Reddit renders those on the client and fetching the page never sees them. That clipping says so in place of its comment section rather than reading as a thread that nobody replied to, and it will never overwrite a fuller clipping of the same post you already took from the thread itself.

Why Markdown, and why a bundle

Markdown is the format a model reads without being taught anything: headings are headings, indentation is nesting, and there is no markup budget spent on layout.

The send does not replace what is already in your bundle, it extends it, and files with the same name replace each other. So a repository and the thread arguing about it can sit in the same bundle in either order, and re-sending a corrected clipping fixes it in place instead of duplicating it. When you are done, the bundler gives you one document with a live token count, so you know it fits before you paste it anywhere.

Nothing is uploaded to us on the way. The clipping is made in your browser, held in your browser's own storage between the clip and the send, and handed to the tab you already have open.
