# Zeli — Hacker News with AI Summaries in 30 Languages

> Zeli (https://zeli.app) mirrors the Hacker News front page in real time, translates every story title into 30 languages, and attaches an AI-generated summary plus a key quote to each story, so readers can decide what deserves a full read. It also digests HuggingFace daily AI papers. Free, no sign-up, installable as a PWA.

Key facts:
- The ranking mirrors news.ycombinator.com exactly and refreshes every 15 minutes.
- Every story has a permanent, citable page per language: https://zeli.app/{lang}/story/{id} — e.g. https://zeli.app/en/story/48808482. These pages contain the translated title, the original title, an AI summary, and a key quote, and never expire.
- Every day has a permanent archive of the full front page: https://zeli.app/{lang}/digest/{YYYY-MM-DD} — e.g. https://zeli.app/en/digest/2026-07-07. The archive index is at https://zeli.app/{lang}/digest.
- Supported language codes: en, zh, es, fr, de, ja, ko, ru, ar, hi, pt, it, nl, pl, sv, tr, vi, th, id, el, cs, da, fi, no, ro, hu, he, uk, bn, ms.
- Summaries are generated by AI from the full text of the linked article; Ask HN threads are summarized from their top answers. Zeli adds summaries and translations on top of Hacker News — discussions stay on news.ycombinator.com.

## Machine-readable endpoints (for agents)

Prefer these over fetching HTML pages — no rendering, no parsing, far fewer tokens:

- **Daily digest as markdown** (best for a daily briefing): https://zeli.app/{lang}/digest/latest.md — the current day's full front page with summaries in one plain-markdown document (~10 KB). Dated archives: https://zeli.app/{lang}/digest/{YYYY-MM-DD}.md (immutable once the UTC day ends; cache them forever).
- **Front page as JSON**: https://zeli.app/api/hn-content?type=top&locale={lang} — array of stories with fields `id, title, url, time, by, score, descendants, type, abstract, quote, image`. Also `type=hot24h` (past-24h top by points), `type=ask`, `type=show`. Existing fields will not be renamed or removed; new fields may be added.
- **RSS**: https://zeli.app/{lang}/rss.xml — ONE item per day containing the whole day's summaries (newsletter model, does not flood timelines).
- **Agent guide / skill file**: https://zeli.app/skill.md — how to use Zeli as an agent, with examples and etiquette. OpenClaw agents can install it from ClawHub: `openclaw skills install @mazzzystar/zeli-hacker-news`.

Etiquette: the digest updates hourly and the front page every 15 minutes — polling more often than that reads cache anyway. Everything above is served from an edge cache; you never need a headless browser for Zeli.
