About Serious Mode – Comment Filter & Summary for Reddit and YouTube
Tired of scrolling past puns, memes and "this" to find a real answer? Serious Mode quietly filters the noise out of Reddit and YouTube comments, so the useful replies rise to the top.
WHAT IT FILTERS
- Joke chains, puns and meme replies ("username checks out", "this is the way"…)
- Laughter-only and one-word replies ("lol", "this", "same", "F")
- Emoji-only, GIF-only and low-effort comments
- Works on new Reddit, old Reddit and YouTube, in 20 languages
YOU'RE IN CONTROL
- Three strictness levels: Relaxed, Balanced or Strict
- Collapse filtered comments (one click to show), hide whole threads, or remove them
- Optionally filter every comment under a word count you choose
- Never filter certain subreddits, and add your own "always filter" and "never filter" phrases
- Every filtered comment says why it was filtered
CLEANER PAGES
- Hide Reddit ads and promoted posts
- Auto-load more replies ahead of where you're reading, so the page doesn't jump
FAMILY-FRIENDLY LANGUAGE
- Swaps swear words for mild ones ("freaking", "jerk"), with a "Show original" link on each comment
- Leaves names and everyday words alone (Dick Van Dyke, cocktail, Scunthorpe)
- Swear jar: see how many words have been swapped
SMARTER WITH GEMINI NANO (CHROME'S BUILT-IN AI)
If your computer supports Chrome's on-device AI, Serious Mode can also:
- Summarise a thread or video's comments: the main point, key points and the comments worth reading in full. Show it as a floating card, a side panel or above the first comment.
- Pick natural replacements for swear words that fit each sentence, in any language
- Tidy clear spelling and grammar mistakes in comments, with a "Show original" link
- Double-check borderline comments before filtering them
These features are marked ✦ in settings and switch on once Gemini Nano has downloaded.
PRIVATE BY DESIGN
- Everything runs in your browser. No account, no tracking, no data sent anywhere.
- The AI features use Gemini Nano on your own device, not a server.
FREE
Serious Mode is free. If it saves you time, you can support it with a coffee from the settings.
