Intelligence, Built In
A C# IDE with embedded local model inference. AI that understands your code semantically, runs entirely on your machine, and needs no API keys.
Download HorizonToday's AI coding tools send your code to external servers for every suggestion.
They bolt a chat window onto an editor that treats your code as plain text.
They require API keys, network connections, and trust that your proprietary code stays private.
On-Device Intelligence
Horizon runs a purpose-trained language model directly on your machine. No cloud dependency. No API keys. No code ever leaves your device.
Type natural language commands in the terminal and Horizon translates them into IDE actions. Build the project. Fix the failing test. Refactor this method. The model understands what you mean because it was trained specifically for IDE operations, with constrained output grammars that ensure reliable, deterministic results.
