// how it works

How it works

  1. Clarify your goal

    List the sources and topics you care about, and decide how stories should be scored and how long your daily briefing should be.

  2. Get the project

    Clone Thysrael/Horizon from GitHub (or use the install path in the run steps below) and skim its README for the parts relevant to your goal.

  3. Install and configure

    Clone or install the package, then configure your sources, scoring profiles and an LLM for summarisation.

  4. Run your first task

    Run one briefing generation, check the English and Chinese output, then tune thresholds and category caps before automating it daily.

// features

Why people love it

Many sources, one briefing

Follow RSS, Hacker News, Reddit, Telegram, X, GitHub, financial news and more in a single daily briefing.

Profile-based scoring

Define scoring rubrics with profiles, set individual thresholds, and merge repeated stories within each profile.

Per-story treatments

Choose summaries, context, solutions or takeaways per category, defined with Markdown prompts and JSON block definitions.

Background and discussion

Add web-researched background and community discussion where they help explain a story, beyond the headline.

Balanced briefings

Cap the briefing's total length and each category's share so one busy topic does not crowd out the rest.

Flexible delivery

Generate English and Chinese briefings as Markdown, publish to Pages, or deliver by email and webhook.

Questions, answered

Who maintains Horizon?

Thysrael, through the Thysrael/Horizon repository, with a demo site at horizon1123.top.

Is Horizon free to use?

Yes — the project is open source under the MIT license as recorded for this listing. You can use, modify and distribute it under the MIT terms.

Does Horizon need a paid API key?

Summarisation and scoring use an LLM you configure, so you typically supply your own API key and pay your provider; Horizon itself is free and MIT licensed.

How does Horizon compare to a plain RSS reader?

An RSS reader shows everything chronologically and leaves triage to you. Horizon scores stories against your rubrics, merges duplicates, adds researched context and writes a finished bilingual briefing — delivered by email, webhook or Pages.

How do I get started with Horizon?

Clone the repository (or use the documented installer), follow the install and configure steps on this page, and run the smallest real task first — run one briefing generation, check the English and Chinese output, then tune thresholds and category caps before automating it daily.
