Serious Mode – Comment Filter & Summary for Reddit and YouTube

Skip the jokes, keep the insight. Filters low-effort comments on Reddit and YouTube and summarises the best ones, in your browser.

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.
