Auto-Refresh a Reddit Thread for New AMA Comments
You're glued to a Reddit AMA, mashing F5 every 10 seconds, and still missing top-level comments because they appear while you're scrolling. The thread is moving fast, your thumb hurts, and that astronaut is answering questions you haven't even seen yet.
Following a live Reddit AMA, whether it's an actor, an astronaut, or a developer, is supposed to be exciting. Instead, it turns into a frantic cycle of scroll, pull-to-refresh, miss a comment, scroll again. The default Reddit experience wasn't built for live events with hundreds of new top-level comments per minute. You end up reading replies to questions you never saw, and by the time you find the actual new content, the upvote window is gone and the same question has been asked 14 times.
The core problem is simple: Reddit's sort-by-new doesn't auto-update the page. You have to manually reload, which resets your scroll position, breaks your reading flow, and makes you miss comments that were posted in the split second between your last refresh and the new page load. For a big AMA (like an r/IAmA or r/nba game thread), that split second is the difference between seeing a reply first and finding it buried.
The fix is a dedicated auto-refresh tool that reloads the page on a precise timer, keeps the sort set to New, and alerts you when the comment count jumps. Here's the exact workflow: open the thread, set Auto Refresh Ultra to refresh every 15 seconds, lock the Reddit sort dropdown to New, and enable a sound alert for when the comment count increases. You'll see new comments within 15 seconds of them being posted, you'll keep your scroll position (because you know the new stuff is at the top), and you'll get that first-reply upvote window before anyone else.
Step by step
- Open the Reddit thread you want to follow. Make sure you're on the full desktop site (old.reddit.com or new Reddit), not the mobile app, since Auto Refresh Ultra works in your browser.
- Set the Reddit sort to 'New' by clicking the sort dropdown at the top of the comments section and selecting New. This ensures that after each refresh, the newest top-level comments appear first.
- Click the Auto Refresh Ultra icon in your browser toolbar. If you don't see it, pin it from the extensions menu (the puzzle piece icon in Chrome/Edge).
- Set the refresh interval to 15 seconds. In the ARU popup, click the Interval field and type
15. Make sure the unit dropdown shows Seconds. - Enable the 'Sound alert on page change' toggle. Click the speaker icon or the checkbox labeled Sound alert when page changes in the ARU settings. This will play a chime when the page content updates (i.e., when new comments appear).
- Click the 'Start' button in the ARU popup. The extension will begin refreshing the tab every 15 seconds. You'll see a small counter in the ARU icon showing the time until the next refresh.
- Keep the interval reasonable. If Reddit slows down or shows extra verification, stop refreshing and restart later with a longer interval, such as 30 or 60 seconds. Follow Reddit's rules and avoid hammering the page.
- Optional: Set a 'Smart refresh' pause. If you're actively typing a comment or scrolling manually, click Smart refresh in ARU and set it to Pause when active on tab. This stops the refresh while you're interacting so you don't lose your place.
- Leave the tab open and let ARU do the work. When you hear the sound alert, glance at the tab, the new comments will be at the top. Upvote, reply, or just read.
- To stop, click the ARU icon and press Stop. The extension will remember your interval for next time.
Why this works better than manual refresh
Manual refresh (F5 or pull-to-refresh) has three fatal flaws. First, it's inconsistent, you never know exactly when to hit refresh, so you either do it too often (waste of time) or too late (miss comments). Second, it resets your scroll position to the top of the page, forcing you to scroll back down through comments you've already read. Third, it offers no alert, you have to stare at the screen waiting for something to change. Auto Refresh Ultra solves all three: it refreshes on a precise 15-second schedule, you never lose your scroll position because you know the new comments are always at the top (since you sorted by New), and the sound alert frees you to work on other tabs while ARU watches the thread for you.
Compared with manually hitting refresh, Auto Refresh Ultra keeps the schedule consistent and lets you focus on the thread. It works on Reddit pages you can open in desktop Chrome, and you can stop it as soon as the live moment is over.
Real scenario: Dan the dad who lost 90 minutes to Ticketmaster was following an r/nba live thread during Game 7 of the NBA Finals. He wanted to see reactions to every play within seconds, but his manual refreshes kept landing on the same old comments. After setting up Auto Refresh Ultra with a 10-second interval and the sound alert, he heard a chime every time a new hot take appeared. He caught the 'Steph Curry just hit a three from the logo' comment within 8 seconds of it being posted, upvoted it, and got 200 karma before the thread even hit 10,000 comments.
Frequently asked questions
Can I auto refresh a Reddit thread safely?
Use a reasonable interval and follow Reddit's rules. For live threads, start around 20 to 30 seconds and slow down if the page shows rate limits, verification, or login prompts. Stop refreshing when the event is over.
Does this work in the Reddit mobile app?
No. Chrome extensions run in desktop Chrome and compatible desktop browsers. Open the Reddit thread in a normal browser tab, set the thread to New, then start the refresh timer from the Auto Refresh Ultra toolbar icon.
Why does my sound alert not play when new comments appear?
Check that your browser allows sound from extensions and that your system volume is on. If the page changes but you hear nothing, use a longer interval and test the alert on a low-stakes page before relying on it during a live thread.
Can I auto refresh multiple Reddit threads at different intervals?
Yes. Open each thread in its own tab and set a separate interval for each tab. Keep the total request load reasonable. Three tabs at 30 seconds is already 360 refreshes per hour.
What interval should I use for an AMA or live sports thread?
Start with 20 to 30 seconds. If the thread is moving extremely fast, use 10 to 15 seconds for a short window, then slow it back down. The goal is to catch changes without overwhelming the page.
