What each one is
Horizon
Horizon is a self-hosted tool that gathers news from sources you configure and uses AI models to rank and summarize them into a daily briefing in English and Chinese. The README shows a ranked daily overview, per-story context and summaries, and notifications sent to Feishu. It is aimed at people who want a personalized news digest instead of browsing many sites.
nanobot
nanobot is an open-source personal AI assistant you run yourself. You can use it in a browser, a terminal, or chat apps like Telegram or Discord to work with files, remember preferences, and schedule tasks. It does not include a model; you connect it to a supported model provider or a local model server.
Best for

Strengths
Horizon
- Open source under the MIT license
- Produces briefings in both English and Chinese according to its description
- Includes a live demo and a configuration guide to get started
nanobot
- Self-hosted, and the README says you can inspect and extend the code
- Works across a browser UI, terminal, and many chat channels
- Supports OpenAI-compatible APIs and local models, so you can choose your provider
Not ideal for
Horizon
- People who want a ready-made news app with no setup, since the README centers on configuration and self-hosting
- Users unwilling to supply AI model access, because the summaries depend on LLM providers
- Anyone needing a verified news source, since output quality depends on configured sources and models
nanobot
- People who want a ready-made hosted service with no setup, since you must supply a model account or local model server
- Non-technical users who are uncomfortable with terminals or configuration, unless they follow the separate non-technical guide
- Teams needing a documented enterprise security model, since the README does not describe one in detail
Trade-offs
Horizon
- The README is truncated here, so detailed setup requirements are not fully visible
- Relies on third-party AI model providers whose costs and availability are outside the project's control
- Latest release is not listed, so version stability is unclear
nanobot
- Requires a model provider account or local model hardware, and costs depend on that choice
- The README is truncated and describes current source, which may differ from the stable release
- Setup involves Python and terminal steps for most users
