Reddit Summarizer - Summarize long Reddit threads with one click
by•
Some long reddit threads are a gold mine. But you need to dig deep in hundreds or thousands of comments to form the conclusion.
To simplify that I automated it all in form of chrome extension with customization to fit your own needs.
With one click it:
- fetches metadata (with all comments)
- cleans it
- sends it to selected AI
- gold, you are looking for
Supported pages:
- Threads
- Subreddits
- Search results

@martin_machava nice product, niche but useful
Product Hunt Wrapped 2025
Nice. Could save me in AITA rabbit holes on the bus. I usually skim 1–2k comments hunting for the update and the one smart reply. Do your summaries keep links to the key comments so I can jump back? Also curious how you handle token limits on huge threads.

@alexcloudstar I clear json metadata and keep only relevant fields for AI to process.
Summarization results can be seen in History section but History is visible only in that specific site. If you like the summary, you can save it and it will always be visible in Save section.
I wonder what are your reddit use-cases. You might be able to automate that by creating your own custom Mode so it's always just one click away.

@chi_hung_wong I was also doing something similar for X (tweeter) and it was also quite difficult. Facebook must be even harder level than that.
With Reddit I was really lucky, the implementation was much much easier than on X or Facebook thanks to open json endpoints to fetch metadata.

Saves me lots of time crawling through pile of trashy comments on reddit. I wish this would work for other forum type websites as well.
Reddit Summarizer
@marek_machava exactly, that was my point while building this extension. Most comments on reddit are low value and only few have what I'm looking for.
What other forums would you like to see similar tools on? If this one gets enough tractions and I see it helps people and they want it, I might expand to other areas/forums.
@martin_machava For example forums based on most common types like XenForo, phpBB, MyBB or WordPress. Som forums are shitty built like continuous loading when scrolling and cannot use classic search bar except built in search.

@german_merlo1Â I added Toolbar with quick action buttons to eliminate clicks to get the result. Extension Popup is still there with more functionality but most basic functions are accessible in Toolbar to save time. And it's looking pretty good, I have to say :D
very nice one! really like the idea and that particular comment asking you when those 'endless threads finally broke you' haha
just curious, what would you do if Reddit came to you and offered you to integrate the tool directly to the Reddit app and website etc?

@yellow_yetti glad I'm not the only one who find it useful. Hard question. Not sure, that would depend on the conditions. First of all, I'm trying to have my own product out there that solves real problems and hopefully some day I can escape 9-5 job. I didn't even think my product could be acquired someday, so not sure, but such an integration could "fix" reddit for all of us.
Does it work with specific subreddits, or is it more general? I'm curious about use cases for developer-focused communities.
Reddit Summarizer
@eddybenchek yes, it's like "copilot" while user is still steering the vehicle. So when you open subreddit, it's analyzing all posts you can see (actually more then you can see, it fetches 100 posts) based on your filter (New, Hot, Relevant,...). Same applies for Search Results.
Interesting idea. This could also be very relevant for other well-known sites. I suggest expanding the project)
Reddit Summarizer
@mykyta_semenov_Â for reddit it was particularly easy thanks to public json endpoints. Same concept for other sites sounds good, I will definitely consider it in the future but it will be another plugin with similar functionality :)
Looks good. Have been looking for such a solution, Few suggestions:
Add dark mode looks weird in dark mode
Clicking on a link in AI summary redirects to new tab instead of the same tab (Optional)
Reddit Summarizer
@kingcold I restrected myself from adding dark mode to MVP on purpose, but now when it's out, I'll do it in following days 🌚
"Referenced link click redirects to new tab" well, let me brainstorm little bit so I get it right.
Scroll down - To me, ideal case would be that if it's a link to a comment in same thread where you are, the page would scroll down to that comment. But it may happen that there's a reference to a comment that is not loaded in your UI because Reddit Summarizer sees more than you see, it sees all the comments, not just those visible to you.
Comment Redirect - that initiates page refresh and summary will be closed (still visible in extension popup but not in toolbar). But I think that's doable to implement so it stays there. You are right, I'll do it, might take some time though.
@martin_machava If its a lot of effort you can ignore it, as its not that big of a deal.
Thanks for working on dark mode!❤️
Reddit Summarizer
@kingcold I did it! Your suggestions are really great!
Dark mode is done. It sync on-the-fly with reddit theme. Works really great!
Comment redirect - if the referenced comment in summary is visible in UI, it scrolls down to it and also highlights that comment for a second and then highlight fades out.
If comment is not in loaded in UI, it will open the comment inside same tab, preserving the last summary.
New version was submitted to chrome store for review. When it's accepted, I'll publish it. Thanks for valuable feedback, Boy :)
I found it through Google, exactly what I was looking for ...great work man

@nikhil_agrawal happy to hear that 🩵 I struggle little bit with reach so it's good to know it can be found on Google but I should work on SEO.
There's an unannounced feature coining out soon soon that will allow users to blur out spam/low-value/AI-slop comments. If you read this, you are first one to know 🙂
Of course, if you see any any issues or got feature requests, just let me know and I will work on it

Thanks@nikhil_agrawal! Big update is coming, waiting for google to approve it. Stay tuned
