For each event it aggregates reporting from a wide range of publishers and produces a short AI-written summary, then lets you drill into the individual articles that formed it. The result is a feed that reads more like a briefing than a link dump. The product covers a broad set of verticals — technology, politics, sports, entertainment, science, crime, economics, international relations and gaming — and lets you follow specific topics, teams, companies and people so the home feed reflects your interests. A newer feature called Radar lets you search what a large library of podcasts (advertised as 165,000+ shows) has said about any topic, company or person, treating spoken-word commentary as a searchable news source alongside written reporting. Particle is funded and operated by Mina Labs, Inc., with a founding team that includes former Twitter product and engineering staff. It is free to use and supported by advertising, analytics and cookie-based personalization, with the option to decline non-essential cookies. **Pricing & Plans:** Free to use. Particle is supported by advertising and personalized recommendations rather than a paid subscription, and visitors can decline non-essential tracking cookies. - **AI multi-source story summaries:** Each story is condensed into a short summary built from many publishers' reporting, so you can grasp the essentials quickly and still see the underlying articles. - **Personalized topic feed:** Follow channels such as technology, politics, sports, science, economics and gaming, plus narrower entities and events, to shape what appears in your feed. - **Radar podcast search:** Query a large index of podcasts to see what shows are saying about a given topic, company or person, alongside the written coverage. - **Article-count context:** Stories display how many articles back each summary, giving a rough signal of how widely an event is being covered. - **Cross-platform access:** Read through the web app and mobile apps, with newsletter delivery available for those who prefer email. **Strengths:** Summaries draw on many sources rather than a single outlet; Broad topic coverage spanning hard news, tech, sports and entertainment; Podcast search adds a source type most news apps ignore; Free to use with an option to decline non-essential cookies **Limitations:** AI summaries are a starting point and can miss nuance in complex stories; Ad-supported model means tracking cookies and personalized advertising; Depth ultimately depends on opening the original articles [Profile (Markdown)](https://openaitools.app/tool/particle.md) ## Zeli Zeli solves the oldest problem with Hacker News: the front page is a list of headlines, and deciding which of the thirty stories deserves your attention means opening all of them. Zeli mirrors that front page, attaches an AI-written summary and a representative key quote to each story, and translates everything into seven languages. The ranking tracks news.ycombinator.com and refreshes every fifteen minutes, so the feed stays current without you checking the orange site directly. The structure is built around permanent, citable pages. Every story gets a URL keyed to its Hacker News item id — zeli.app/story/{id} in English, or zeli.app/{lang}/story/{id} for the other languages — carrying the translated title, the original title, a summary, a key quote and translated highlights from the discussion. Every day also gets a permanent archive of the complete front page, so a digest can be retrieved after that day has scrolled away. Alongside the news feed, Zeli digests HuggingFace's daily AI papers with translated titles and summaries, which makes it useful for keeping up with research as well as with developer chatter. Content languages are English, Chinese, Japanese, Korean, German, Spanish and Russian, with English served at the root and no language prefix. There is no account, no API key and no cost; an RSS feed bundles one item per day instead of flooding your reader, and the site can be installed as a PWA. For programmatic use, Zeli also publishes plain-markdown daily digests, JSON endpoints and an RSS feed aimed at feeds and AI agents. It requires no JavaScript and is served from an edge cache, so it is unusually light to read. **Pricing & Plans:** Free. No account, no API key and no payment; the full site, the RSS feed and the machine-readable digests are all available at no cost. - **AI summaries on every Hacker News story:** Each story carries a short summary generated from the linked article plus a standout key quote, so you can judge relevance before clicking through. - **Seven-language translation:** The whole feed — titles, summaries and top comment highlights — is available in English, Chinese, Japanese, Korean, German, Spanish and Russian. - **Daily front-page archive:** Every day gets a permanent page containing every story that hit the front page, retrievable long after the feed has moved on. - **HuggingFace AI paper digests:** Daily AI papers are surfaced with translated titles and AI summaries, making Zeli a research reader as well as a news reader. - **Machine-readable outputs:** One-item-per-day RSS feeds, plain-markdown digests, JSON endpoints and a sitemap make Zeli easy to pipe into readers or AI agents. **Strengths:** Turns the Hacker News front page into a fast, scannable daily brief; Seven languages with genuinely translated titles, summaries and comment highlights; Permanent, citable story and daily archive pages that never expire; Free, no signup, no API key, installable as a PWA **Limitations:** Summaries are machine-generated and are not fact-checked by a human; Real summaries exist only in seven languages — other locales fall back to English; It covers Hacker News and HuggingFace papers only, not your own reading list or arbitrary URLs; Keys off Hacker News ranking, so niche topics that never hit the front page are not included [Profile (Markdown)](https://openaitools.app/tool/zeli.md) ## Frequently Asked Questions ### How do Particle and Zeli compare in monthly traffic?
