signal-track信号追踪

What it does

signal-track is an AI-native information tracking system and a CLI tool for continuous, topic-based intelligence monitoring. signal-track is not a traditional news reader and not a general recommendation feed. The system is built around long-running topics: users define persistent tracking tasks, and the platform continuously monitors information sources, detects meaningful updates, filters noise, and surfaces high-value signals. In other words, it converts one-time information queries into persistent tracking tasks.

• * Track ongoing topics (e.g. "OpenAI releases", "NVIDIA earnings", "China policy changes")
• Aggregate updates from multiple information sources
• Deduplicate and structure incoming information
• Provide summarized updates and timelines
• Support deep-dive analysis on specific events

When to use

Use signal-track when:

• * You need continuous monitoring of a topic over time
• You want to avoid missing important updates
• You are tracking fast-moving domains (AI, finance, policy, etc.)
• You need structured, decision-relevant information instead of raw news

Do NOT use signal-track for:

• * General browsing or entertainment content
• Pure one-off trivia or random browsing (unless the user explicitly asks for one-off news/article search or browsing)

Core concepts

• * Topic: A long-running information tracking task that can be expressed through a natural language description, structured keywords, and entity references.
• NewsCard: The atomic information unit delivered to users(or agents).

• * Source: Any information producer the system monitors.

• * Feed: A stream of news cards associated with a topic or a user's followed topics, ordered recency.

Key capabilities

• * Create and manage topics
• Subscribe/unsubscribe to topics
• Retrieve topic details by id
• Search within tracked signals
• Fetch full article content
• Trigger deep analysis on selected items

Example use cases

• * Track a company (e.g. Tesla, Apple) for investment decisions
• Monitor AI model releases and benchmark progress
• Follow policy or regulatory changes in a region
• Track competitors or specific products
• Provide simplified explanations of complex information (easy-to-understand summaries)
