## Summarizer.org

Summarizer.org is one of the flagship tools in a larger family of free AI writing utilities — the same site also offers a paraphraser, paragraph rewriter, AI detector, humanizer, grammar checker, essay tools and dozens more generators. The summarizer itself is the core product and it is aimed at students, researchers, writers and professionals who need the gist of a long document fast.

The workflow is deliberately simple: paste your text into the box, or use the "Add URL" option to pull in a published article, or upload a TXT, DOCX or image file. A slider controls how much of the original content the summary retains, and you can toggle between a flowing paragraph, bullet points or a custom format. For longer or higher-stakes jobs an "Advanced AI" mode and an instructions field let you steer the output, and summaries can be downloaded as a .docx file or copied straight to the clipboard.

It advertises multi-language summarization, so you do not need to translate source text first, and it presents itself as privacy-conscious with data not shared with third parties. A limited history and an Android app are also part of the offering. As with any AI summarizer, very technical or ambiguous source material may need a manual pass, so it is best treated as a fast first draft of the key points rather than a final reference.

**Pricing & Plans:** Freemium. The summarizer is free for up to around 1,200 words per task without an account, and includes key features like URL summarization, length control and .docx download. A paid Premium tier (roughly $7 billed monthly, or about $5.6/month billed yearly) unlocks unlimited use, accessible history and higher limits. Note that other tools on the same site follow the same free-plus-premium pattern, so always check the current plan page.

- **Multiple input types:** Summarize by pasting text, adding a published article URL, or uploading a TXT, DOCX or image file — no manual transcription required.
- **Paragraph, bullet points or custom:** Choose bullet points for a quick scannable overview, a traditional paragraph summary, or a custom format tailored to your needs.
- **Adjustable summary length:** A slider lets you keep a longer, more detailed summary or compress hard to a short 50% version, so output matches your word budget.
- **Multilingual summarization:** Generate summaries in many major languages including Spanish, Portuguese, French and German without translating the source text first.
- **Export and copy:** Download the finished summary as a .docx file or copy it to the clipboard for use in your own document.

**Strengths:** No sign-up required for basic summaries; Handles text, URLs, documents and images in one place; Adjustable length and both paragraph and bullet-point output; Multi-language support without pre-translation

**Limitations:** Free tier caps input at roughly 1,200 words per task; No-account history is not saved, so you lose past summaries; Summary quality on highly technical or nuanced content can miss subtleties; The site is ad-supported, which can feel cluttered

## 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
