Mosaic

简体中文 | English

"Reintegrate the scattered fragments of oneself"

A digital second brain that combines note-taking with emotional visualization, helping you record thoughts, track moods, and integrate the scattered fragments of daily life.

Origin

I realized that even though I have memorable moments every day, they gradually fade away over time. So I wanted to develop an app to organize my scattered life fragments, allowing me to recall the scenes and moods of those moments later. That's how Mosaic was born.

Getting Started

1. For data security, you first need to deploy your own Mosaic backend service on your own server to manage your private data
   1. mkdir mosaic-server
   2. cd mosaic-server
   3. Create a .env file in this folder, refer to .env.example for content, and modify the configuration items as needed (remember to change the username and password)
   4. Also create a docker-compose.yml file in this folder, simply copy docker-compose.yml
   5. Go back to the mosaic-server folder and run docker-compose up -d to start
   6. Note: If you encounter permission issues with file uploads, run chown -R 1000:1000 ~/mosaic-server/storage ~/mosaic-server/logs to fix directory permissions
   7. Afterwards, you can configure reverse proxy to your own domain
2. Download the client from releases and connect to your own server
