Show HN: HN Update – Hourly news broadcast of top HN stories

Original Article ↗ Hacker News Discussion ↗

An AI-generated “HN Update” service turns the top Hacker News posts into an hourly, radio-style audio brief, complete with background music and waveform visualization. Listeners praise it as a hands‑free way to keep up with tech news, especially if expanded into longer daily or morning summaries with archives, podcast/RSS distribution, personalization and better UI controls (speed, volume, story index, music toggle). Critics question its efficiency compared to skimming the site, note occasional hallucinated details, and worry that automated summaries lose the human tone and nuance that make comment threads valuable.

Overall reception

  • Many commenters find the hourly HN audio recap clever, useful, and entertaining; some compare it to NPR/BBC-style news.
  • Others say they wouldn’t use it regularly, preferring to skim HN directly; several describe it as more “entertainment” than an efficient way to keep up.

Desired formats & cadence

  • Strong preference for less frequent, longer briefings: daily, 2–4 times per day, or morning/afternoon/evening.
  • Multiple requests for archives (days or a week back) so people can catch up.
  • Several suggest publishing as a podcast via RSS for easier subscription and use in podcast apps and car systems.

Personalization & content selection

  • Requests to:
    • Include more than the top 5 posts; maybe top 10–20, or top/best from last 24 hours.
    • Filter or focus on most-upvoted, most-commented, or user-interest-based stories.
  • Ideas for personalization using embeddings or user history (favorites/upvotes, topic keywords), with notes about exploration vs exploitation tradeoffs.

Audio experience: voice, speed, music

  • Voice quality is generally praised; it uses OpenAI’s TTS. Some propose ElevenLabs as an alternative, but cost is a concern.
  • Many want adjustable playback speed (fine-grained steps like 1.2–1.25x, up to 3x). Some already listen comfortably at high speeds.
  • Background music is divisive:
    • Some like the “news-station” feel.
    • Many find it distracting or manipulative and want an option to disable it.
    • Suggestions include separate music track, ducking, or muting music when speed changes.

UX, features & distribution

  • Requests for:
    • Links to the covered stories under the player and highlighting current segment.
    • Story index and waveform segmentation per story.
    • Display of total and current time, number of stories, volume slider.
    • Transcript of each broadcast.
    • Mobile‑friendly design, PWA/app, and widgets for one-tap play.
    • Ability to filter out certain kinds of stories.

Accuracy, trust & AI behavior

  • At least one concrete hallucination is reported (misinterpreting a meta formatting comment as concern about C++), raising trust issues.
  • Suggestions to tighten prompts (e.g., emphasize using only provided text; treat comments as possibly meta or non-factual).
  • Some see this as part of a broader shift toward AI-transformed consumption of public content, with open questions about bias and reliability.

Implementation & cost notes

  • Uses HN API plus scraping; Wavesurfer for the waveform; OpenAI TTS for voice.
  • Some discuss handling JS-heavy pages and PDFs, and note that TTS can get expensive at scale.
