Changelog

Added

• Swipe to react on touch devices. Swipe a post right for Like and Save, or left for Dislike and Report; a short swipe opens the buttons and a long swipe reacts in one motion.
• The Browse Most Discussed page ranks articles by how many other posts and discussion threads link to them. You can also add this as a feed.
• Articles that use mathematical notation render properly in the reader: equations written in LaTeX appear as typeset math instead of raw markup.

Changed

• Browse is reorganized into tabs: posts, interests, feeds, and people.
• Posts with vague or repeated titles read more clearly: when a feed gives every item the same title (for example, a project whose release notes are all labeled with the product name) or leaves out the real headline, Scour fills in a more descriptive title from the article's page, heading, or link.

Added

• Turn an article you liked into interests. Open any post and choose Add Interest: Scour reads the article, suggests a few topics, and you pick the ones to follow. See the interests docs.
• See which articles discuss a story: open any article to find the other articles that link to it, with sources you follow listed first.
• When articles in your feeds discuss a widely cited original story, the original itself can appear in your feed. Select a post to preview the top articles covering it, or open the coverage label to see every covering article on a dedicated page.
• Find all of your recommendations in one place. The new Recommendations page gathers the interests and feeds we suggest for you.

Changed

• Screen reader navigation got smoother: moving between pages announces the new page title and places your reading position at the start of the content, rating a post returns your focus to the button you pressed instead of dropping it, removing a filter chip states clearly what it removes, copying a link confirms it out loud, and decorative icons stay silent instead of announcing as unlabeled images. See Accessibility for everything Scour does for assistive technology.

Changed

• Scour works better with screen readers and keyboards. Every post in the feed is a labelled article whose actions (save, like, report, share, and the rest) are reachable with assistive technology; menus support arrow-key navigation; filter changes, search results, and newly loaded posts are announced as they happen; checking the humanity box announces the result and keeps your place; and form errors land your focus on the field that needs fixing. See Accessibility for the full picture.
• Posts from sites that repeat the same footer, subscribe pitch, or link list in every article get cleaner treatment: the repeated block is detected automatically and ignored when Scour matches posts to your interests, and hidden when you read the post. This fixes posts being tagged with the wrong interest because of words like RSS appearing in a site's footer rather than the article itself.
• Twitter/X threads shared through Thread Reader App show the thread's opening line as the title, instead of a generic "Thread by @username on Thread Reader App" label, so you can tell what each thread is about at a glance.
• To read an article's full text on Scour, you'll need to be logged in; logged-out visitors see a preview with the headline and summary.

Changed

• Signing up got faster and more reliable: your account is created right away even when interest generation runs slow (the interests appear on your feed moments later), correcting a taken username or email keeps the interests Scour already generated for you instead of regenerating them, and letting the humanity check expire while you write your description gives you a clear prompt to re-verify instead of a generic error.
• Adding feeds got more forgiving: pasting outline lines copied out of an OPML file works, URLs wrapped in quotes work, and addresses that differ slightly from a feed Scour already knows (http vs https, trailing slashes, www prefixes) match it directly instead of failing.
• Trying to add a site that does not offer feeds, like X (Twitter), Telegram, Facebook, or Instagram, gets a clear explanation instead of a generic error.
• Feed additions that failed are retried automatically, and if the address matches a feed Scour already knows under a slightly different form, you get subscribed to it automatically.

Added

• Posts in your feed show a small label next to the title indicating the kind of content, such as videos, podcasts, academic papers, recipes, and news articles.
• Keep reading past the end of your feed: when you reach the end of your recent posts, Scour continues with older posts from your subscribed feeds under an "Earlier from your feeds" divider. After that, an "Explore all of Scour" button matches your interests against every feed on Scour, not just the ones you subscribe to.
• User testimonials on the homepage.

Changed

• Returning to your feed after reading an article keeps your exact place: the feed stays as you left it, with the article you just read highlighted and its rating row opened for you. If you come back after more than half an hour away, the feed refreshes to the latest posts with that article pinned to the top so you can still rate it.

Changed

• Fixed a bug where returning to your feed after opening an article could leave you on a stale, out-of-date version of it, most noticeably in the installed app on iOS. Coming back to a feed that has gone stale refreshes it to the latest, while a quick glance away keeps your place.
• Fewer wrong-language posts: articles with Chinese, Japanese, or Korean titles are classified by their title's script, so they stop slipping into your feed labeled as a language you read when their body text happens to be mostly English (code samples, product names).
• Paywalled articles become readable when they open up: some sites (like LWN and The Consensus) publish articles for subscribers first, then release them free about a week later. When that happens, Scour refreshes the article with the full text and resurfaces it, so you get the complete piece once it is freely available.

Added

• Subscribe to long-form blogs published on the AT Protocol (standard.site). Paste a Bluesky handle, DID, or at:// publication link into the subscribe box and Scour pulls in their posts like any other feed.

Changed

• Cleaner article bodies: stray CSS that some sites leak into their page text is stripped out of post content, while code samples shown inside fenced code blocks are preserved.

Added

• Score breakdown on each post: hover over a post's title to see how its score splits between meaning-based and vocabulary-based matching, and which interest it matched closest with.
• "Show advanced" view on your own interests: see the terms and weighted topic facets Scour uses to score articles against each interest.

Changed

• Significantly improved interest matching: Scour now scores each post by both how closely its meaning matches one of your interests and how directly it talks about that interest in the topic's own vocabulary. Ambiguous interests like "Rust" or "Python" should pull in the right articles more reliably, and specific interests should find their exact subject matter more often. An interest's specificity tier (Broad, Normal, Specific) controls the balance between the two signals. See How Ranking Works for more.
• Title keyword bolding is driven by your closest matching interest for each post, instead of globally rare words, so it's easier to see at a glance why each post matched.

Added

• Language settings cover more languages, including Basque, Icelandic, Māori, Swahili, Welsh, and others.

Changed

• Improved language classification: posts Scour previously left as "undetermined" get a second pass through a more accurate detector, so your language filters catch more of the right posts.

Changed

• Your feed is paginated by default. If you prefer to keep scrolling, a new link at the bottom of the feed switches you to infinite scrolling in one click. You can always switch back from Settings.

Changed

• Saved items may reappear in your feed in lieu of interest or feed recommendations.

Added

• Filter posts by domain: you can click the domain under any post to see all posts Scour has indexed from that website.
• Personalized RSS feed links: logged in users who copy RSS links have the as and token parameters, which help Scour attribute your clicks. Clicks are used to improve your interest recommendations and slowly shift which sources and topics you see more or less of over time.

Added

• Expanded domain blocklists: fewer low-quality, AI-generated, and spam sources in your feed.

Changed

• Cleaner URLs: Scour strips 15 more publisher-specific tracking parameters, including retroactively on existing posts.
• Code blocks in post previews preserve their indentation.

Added

• Weekly email digests include a section with posts that come from feeds you don't subscribe to.

Changed

• Improved look and feel for the weekly email digests.
• Improved security by tightening Content Security Policy (CSP).
• Automatic feed discovery is faster when you click to show the feeds for a post

Added

• Browse popular interests by category: the popular interests page groups interests into categories like Food & Cooking, Arts & Design, Science & Nature, and more. Technology interests are further organized into subcategories (AI & ML, Languages & Tools, Systems & Infrastructure, etc).
• Clicking on a post's row shows a brief snippet from the post. This replaces the setting that enabled showing post summaries while browsing the feed. Clicking Read more takes you to the post preview on Scour.

Added

• Saved posts: you can save posts without reacting to them. You can use this to mark posts that you want to read later, without having them influence your feed.
• Click a post's row to show the action buttons (saving, reacting, flagging, showing feeds, etc). This replaces the previous inline buttons and ... menu.

Changed

• Improved the post preview, so you can more comfortably read posts on Scour. This also includes code syntax highlighting.
• Progressive Web App (PWA) prompt appears on desktop for Chrome and Chromium-based browsers.

Added

• Your feed adapts to your engagement: topic areas and websites you actively read and react to get more space in your feed, while those you skip or dislike get less. Your interests still control what topics appear, but your engagement shapes how much of each.
• Reactions have moved: instead of small buttons on every post, you can react from the ··· menu, or use the prompt that appears after you finish reading an article. This makes the feed cleaner and the reaction buttons easier to click on mobile.
• Wildcard domain blocking: enter *.example.com in your Excluded Domains list to block a domain and all its subdomains, or *.ai to block an entire TLD.

Changed

• Improved feed diversity: your feed better balances coverage across your interests, avoids showing the same story from multiple outlets, and mixes familiar and new sources more naturally.
• Feeds that have less than 25% of their content in a language you understand will no longer be recommended.

Added

• Post previews: enable "Show post previews" in Settings to see a short summary beneath each post title. Email digests include previews automatically.

Changed

• Imrpoved ranking quality and performance.

Changed

• Improved feed diversity: your feed better balances coverage across your interests, so a single dominant interest is less likely to crowd out the rest.

Added

• User profiles show clickable stats (interests, feeds, likes) below the feed title, linking to browsable pages for each. You can explore another user's interests, feeds, and likes from their profile.

Changed

• Articles with clickbait-style emoji prefixes (such as the siren, rocket, or fire emojis) are demoted in ranking.

Added

• Interest specificity tiers: each interest can be set to Broad, Normal, or Specific, controlling how strictly articles must match. Edit any interest to change its specificity.
• If an article did not appear in your feed and you think it should have, you can look into why on the Why didn't I see this? page.

Changed

• New signup experience: describe your interests in a paragraph and Scour extracts specific interests using AI.
• RSS users can sign up by importing an OPML file to get feeds and interests set up in one step.

Changed

• Performance improvements: loading your feed should take under 100 milliseconds, and many will be under 50 milliseconds.

Added

• Inferring interests from feeds: When you upload an OPML file, Scour analyzes your feed subscriptions to suggest interests you might want to add. You can also generate interest suggestions from your existing feeds via the "Suggest from my feeds" link on the Interests page.
• You can change your email address in Settings.

Added

• You can unsubscribe from email updates by clicking the unsubscribe link in the email.

Changed

• Improved relevance scoring: posts are ranked by how well they match your strongest interest, rather than averaging across all of your interests. If you have diverse interests, you should see better matches across the board.
• Removed the ML-based quality classifier, which was incorrectly filtering out legitimate content.
• Fixed a bug where posts from Bluesky would show up with the title as "Bluesky", rather than the post content.
• Feed ranking is faster.

Added

• Brand new homepage, including a live demo, a brief description of how it works, and links to the docs and platform-specific guides.

Changed

• Fixed a false "offline" warning that appeared on Kindle and other limited browsers even when connected to the internet.

Added

• Comprehensive docs describing how Scour works and how to use it, as well as guides for RSS users and readers of Hacker News, arXiv, Reddit, and Substack.

Changed

• Renamed the "Hot" time frame to "Fresh", because that mode balances relevance with recency, not popularity.

Changed

• Prevent duplicate posts from showing up in the feed.

Added

• Scour is an app (technically, a Progressive Web App). You can add it to your home screen on mobile by following the instructions in the popup.
• New logo!
• You can search your interests and feeds using the search icon on your Interests and Feeds pages.
• Listicle-style titles (for example, "The Top 10 ..." or "5 ways to ...") are penalized to reduce the prominence of these types of titles in your feed.

Changed

• RSS/Atom/JSON feeds exported from Scour include changelog updates and blog posts about Scour.

Changed

• Improved paywall detection for Ghost-powered newsletters.

Added

• Keyboard shortcuts! You can navigate Scour using your keyboard. Type ? to show the available shortcuts.

Added

• Feed autodiscovery: when you click Show Feeds for a post (in the More Options menu), Scour will automatically check the website the comes from to see if it has a feed. If Scour finds a new feed for that website, Scour will include it in the list of feeds. This makes it easier to subscribe for more content from that site.

Changed

• Keywords in post titles are bolded slightly to make the feed easier to scan.

Added
