# tl;dr HN

> Daily AI-generated summaries of top Hacker News stories (200+ points). Each
> story gets a 2-3 sentence tl;dr of the article plus 3-5 key perspectives
> distilled from the top comments, each tagged with a sentiment that is
> relative to the article's argument (does the commenter agree with the
> author?), not the underlying topic.

The front page at https://tldrhn.io shows the latest day, refreshed once a
day around 10:00 UTC. Every day is also kept in a permanent archive, and
every story has a stable permalink. Summaries are generated by Claude from
the Hacker News API and the linked articles. There are no accounts, no
tracking walls, and no paywall.

## Data

- [JSON feed](https://tldrhn.io/api/summaries): the latest day's stories with
  rank, title, article URL, HN discussion URL, permalink, points, author,
  comment count, tl;dr, and discussion perspectives with sentiment.
  CORS-enabled, no auth required.
- [Markdown feed](https://tldrhn.io/summaries.md): the same data as plain
  Markdown, convenient for LLM consumption.

## Archive

- Day pages: https://tldrhn.io/day/YYYY-MM-DD preserves each day's front page
  exactly as it appeared (e.g. /day/2026-06-10).
- Story permalinks: https://tldrhn.io/day/YYYY-MM-DD/<id>-<slug> is the
  permanent page for one story, under the day it first reached the front
  page. <id> is the Hacker News item id.
- [Archive index](https://tldrhn.io/archive): list of all archived days.
- [Sitemap](https://tldrhn.io/sitemap.xml): every day page and story
  permalink, kept current automatically.
