Use case
Turn a Reddit thread into Markdown for ChatGPT
Convert a Reddit discussion into clean Markdown you can paste into ChatGPT or Claude — plus what to do when Reddit blocks the request.
Reddit threads are some of the most useful things to hand an AI: a real question, a dozen real answers, and the disagreements between them. They are also among the hardest pages to fetch automatically.
Reddit actively blocks automated readers. Sometimes a thread converts cleanly; often the request is refused before a single comment comes back. This page covers both outcomes, because pretending otherwise would waste your time.
Mixed results
old.reddit.com URLs convert most of the time. Standard www.reddit.com links are frequently refused, and there is no server-side fix for that — copying the thread and pasting it in is the reliable route for Reddit.
Step by step
- Copy the thread's URL from your browser's address bar.
- Try the old.reddit.com version first — replace www.reddit.com with old.reddit.com. The older interface serves its content as plain HTML and converts far more reliably.
- Paste it into the converter and press Convert.
- Switch the Links toggle off — Reddit comments are dense with links that add tokens without adding meaning.
- Copy the Markdown and paste it into your AI chat with a question like 'summarise the main disagreements in this thread'.
Worth knowing
- Long threads run to tens of thousands of tokens. Check the token count before pasting — it tells you whether the whole thing will fit.
- Add ?sort=top to the URL to bias toward the comments most people agreed with.
- If the conversion is blocked, copy the thread from your own tab and paste it in — you are already logged in there. That is the advantage a server never has.
Questions
- Why does old.reddit.com work better?
- The old interface renders comments in the HTML the server sends. The current one builds them in the browser afterwards, so a server-side fetch sees an empty shell even when it isn't blocked outright.
- Can I convert a whole subreddit?
- Not in one go — the converter handles one page at a time. Converting a subreddit's front page gives you the post titles, which is sometimes enough to decide what to read.
