Horizon
Horizon is a Python-based AI-powered news aggregation tool that autonomously fetches, summarizes, and ranks news from multiple sources, delivering daily briefings in English and Chinese. It supports multiple LLM providers (Claude, GPT, Gemini, DeepSeek, Ollama) and integrates with notification platforms like Feishu and email.

What Horizon is
Built in Python using the uv package manager, Horizon aggregates RSS and web feeds, applies LLM-driven summarization and ranking via pluggable AI backends (including MCP support), and distributes formatted briefings through webhooks, email, and bot integrations. Architecture enables modular source addition and flexible LLM provider switching.

Best use cases
Implementation considerations
- Configure LLM provider credentials (API keys) and select primary backend; multiple providers require per-provider authentication and may incur costs.
- Define news sources by RSS/web URL; Horizon's ranking and summarization quality depends on source diversity and relevance curation by the operator.
- Schedule execution via cron or cloud scheduler; daily briefing cadence and time zone handling must align with intended audience.
- Validate notification integrations (Feishu bot tokens, email SMTP credentials) before production deployment to ensure delivery.
- Monitor LLM costs and token usage; summarizing many articles daily can accumulate significant API charges depending on provider and model selection.
When to avoid it — and what to weigh
- Real-time News Alerts Required — Horizon is designed for daily or scheduled briefings; it is not architected for sub-second real-time alerts or streaming breaking news updates.
- Proprietary News Licensing or Paywall Content — The tool aggregates public RSS and web sources. Scraping paywalled or licensed news content may violate terms of service or copyright; users must ensure compliance.
- Minimal LLM Budget or Latency Constraints — Summarizing and ranking articles daily incurs per-request LLM costs and processing time. High-volume deployments or cost-sensitive environments may face budget or SLA challenges.
- Mission-Critical Accuracy Guarantee — LLM-generated summaries can hallucinate, misinterpret, or omit nuance. Relying on Horizon for legal, financial, or life-critical decisions without human review carries risk.
License & commercial use
MIT License permits unrestricted use, modification, and distribution for commercial and private purposes, provided the license and copyright notice are retained.
MIT is a permissive OSI-approved license. Commercial use, modification, and redistribution are permitted. However, users are responsible for compliance with terms of service of underlying LLM providers (OpenAI, Anthropic, Google, etc.) and news source licensing; verify that summarizing and republishing news does not violate third-party agreements.

Stores LLM API credentials and notification tokens (email, Feishu); ensure these are managed via environment variables or secure vaults, never hardcoded. Web scraping and RSS fetching can be vectors for malicious payloads if sources are untrusted; validate and sanitize fetched content before summarization. No cryptographic signing or authentication for briefing delivery noted; consider adding integrity checks if briefings are redistributed.
Alternatives to consider
Feedly / Inoreader
Commercial SaaS RSS aggregators with built-in AI summaries, but require subscription and offer less customization of LLM backends or delivery channels.
OpenAI / Anthropic API + custom script
Lower-level, build-your-own approach; offers maximum control but requires more engineering effort and lacks pre-built integrations for sources, ranking, and multi-format delivery.
n8n / Zapier automations
Visual workflow platforms for aggregation and notification, but less specialized for news summarization and ranking; may be overkill for simple daily briefing needs.
