Crucix — Personal Intelligence Agent for Multi-Source Monitoring

Introduction

Crucix is an open-source personal intelligence agent that continuously monitors multiple data sources and alerts you when something relevant changes. It aggregates signals from news feeds, social media, GitHub repositories, financial data, and custom APIs, then uses AI to filter noise and surface only the information that matches your interests.

What Crucix Does

• Monitors dozens of data sources including RSS, Twitter, Reddit, GitHub, and APIs
• Uses LLM-based filtering to separate signal from noise based on your interests
• Sends notifications via email, Slack, Discord, or webhooks when relevant events occur
• Maintains a searchable timeline of all monitored events with source attribution
• Runs scheduled intelligence reports summarizing trends across your watched topics

Architecture Overview

Crucix runs a Node.js server with a scheduler that periodically fetches data from configured sources. Each new item passes through a pipeline of filters: keyword matching, deduplication, and an optional LLM classifier that scores relevance against your defined interest profiles. Items above the relevance threshold are stored in a SQLite database and dispatched through configured notification channels.

Self-Hosting & Configuration

• Clone and run with Node.js 20+ or deploy with Docker
• Add data sources through the web UI or by editing the YAML config file
• Define interest profiles with keywords, topics, and example queries
• Configure notification channels (email, Slack, Discord, ntfy, webhooks)
• Set monitoring frequency per source from real-time to daily digests

Key Features

• AI-powered relevance filtering that learns from your feedback
• Unified timeline aggregating all sources with full-text search
• Scheduled digest reports with trend analysis and summaries
• Privacy-focused design with all data stored locally
• Extensible source system for adding custom data providers

FAQ

Q: Does it require an LLM API key? A: The AI filtering is optional. Keyword-based filtering works without any LLM. Adding an API key enables smarter relevance scoring.

Q: How many sources can it monitor? A: There is no hard limit. Practical limits depend on API rate limits and your server resources.

Q: Can I export my data? A: Yes. All data is stored in SQLite and can be exported as JSON or CSV.

Q: Does it support monitoring private repositories or APIs? A: Yes. Configure authentication tokens for any source that requires them.
