TrailSnap (行影集) | AI-Powered open-source photo album for travel & life memories.（AI赋能的开源相册工具，珍藏旅行与生活点滴）

What it solves

TrailSnap is an AI-powered photo album application designed to help users organize, record, and relive their travel experiences. It transforms raw photos into structured memories by automatically extracting travel-related data and providing intelligent organization tools.

How it works

The system uses AI models to analyze photo content, perform OCR on travel documents (like train tickets), and recognize faces and scenes. It indexes these photos into a database (using pgvector) to enable semantic search and automatic categorization. It also includes an AI Agent and CLI that allow users to interact with their photo library via natural language to generate travel diaries or perform tasks.

Who it’s for

Travelers and photography enthusiasts who want a self-hosted, private AI data center for their memories, avoiding reliance on third-party cloud services while gaining advanced organization features.

Highlights

  • Intelligent Organization: Features face recognition, scene classification (e.g., night views, pets, food), and smart search based on people, content, or time.
  • Travel-Specific Tools: Automatically recognizes train tickets and itineraries to extract travel information.
  • Geographic Visualization: Includes a footprint map to view photos by province, city, or district, and tracks visited 5A-level scenic spots.
  • AI Agent Integration: Supports natural language interaction to generate travel diaries and integrates with platforms like OpenClaw and Claude Code.
  • Memory Recovery: Generates annual reports with statistics on cities visited, distance traveled, and a timeline of memories.
