Astrolabe - Semantic Search for Nextcloud

Find your content by meaning, not just keywords. Astrolabe brings AI-powered semantic search to your Nextcloud, helping you discover documents, notes, calendar events, and files through natural language.

Features

Semantic Search: Search across Notes, Files, Calendar, Deck, and more using natural language queries

Unified Search Integration: Results appear in Nextcloud's global search bar alongside traditional results

Background Indexing: Your content is automatically indexed for instant semantic search

Vector Visualization: Explore your content in an interactive 2D visualization showing semantic relationships

Hybrid Search: Combines semantic understanding with keyword matching for best results

How It Works

Astrolabe connects to a semantic search service that understands the meaning of your content. Instead of exact keyword matches, you can search for concepts - ask "meeting notes from last week" or "recipes with chicken" and find relevant documents even if they don't contain those exact words.

Getting Started

1. Install and enable the app

2. Grant background access to allow indexing of your content

3. Start searching with natural language in Nextcloud's search bar

See documentation for configuration details.
