cosma 0.4.0

Search engine for your files!

Cosma

Search engine for your files!

[!CAUTION] This software is in early alpha! There will be lots of bugs. If you encounter any, please report them to the issue tracker.

How It Works

Choose which directories to index, and Cosma will process all files in those directories into a search-optimized index. It'll also watch for changes to keep the index updated.

After files are indexed, you can search for them with natural language! Cosma uses vector-powered search to find files quickly and easily.

Cosma can run 100% locally or in the cloud.

Get Started

Cosma has been tested on MacOS ARM and Windows. Linux support is coming soon!

Installing

Cosma can be downloaded from PyPI. We highly recommend you do this with uv.

uv tool install cosma

Upgrading

To upgrade to the latest version:

uv tool upgrade cosma --no-cache

Setup

Make sure you have Ollama installed.

Cosma has a backend to serve search queries, so it must be started first. This needs to always be running to watch for file changes and process files in the background.

cosma serve

Running

To start the terminal UI and start searching, run search.

[!IMPORTANT]
The backend must be running for this command to work (see above).

cosma search /path/to/directory/to/search

[!WARNING] This will begin processing all files in the directory specified, which will take some time if running locally.

CLI

Cosma includes a CLI with three output modes:

• default - Rich formatted output with colors and tables for interactive use
• --plain - Simple text output without colors, for piping and scripts
• --json - Structured JSON output for agents and programmatic access

cosma search "my query"               # Search indexed files
cosma index /path/to/dir              # Index a directory
cosma status                          # Check backend status
cosma watch add /path/to/dir          # Watch directory for changes
cosma files stats                     # Get file statistics

Run cosma --help for all commands.

MacOS App

We're also working on a Mac app! If this seems like a useful project, give us a star!
