PersonalAI

A lightweight Windows desktop app for chatting with LLM providers via a floating system-tray UI.

Getting started

1. Download the latest release from https://github.com/vasantbala/PersonalAI/releases
2. Extract the zip to a folder of your choice
3. Set your API key(s) as environment variables (see below)
4. Edit appsettings.json to configure your providers
5. Run PersonalAI.exe

Configuration

appsettings.json supports multiple providers. Set ApiKey to a literal value or reference an environment variable using ${VAR_NAME} syntax.

        "ApiType": "openai",

Releasing

Create and push a version tag to trigger a GitHub Release with a self-contained win-x64 executable:

git tag v1.0.0
git push origin v1.0.0

The release workflow builds, publishes a single-file exe, and uploads it to GitHub Releases automatically.
