Hadal
Available nowLocal AI companion
A programming companion that never leaves your hardware.
Hadal is a local programming companion named for the deepest zone of the ocean. It runs on your own hardware with no API keys and no per-token billing — and because nothing leaves the machine, nothing it reads can leak.

Two brains, one persona
A 7B model that answers at reading speed on a laptop CPU, and a 30B mixture-of-experts model on a desktop GPU for multi-file drafts and first-pass review. Same persona, same commands, switched with one flag.
It knows what it doesn't know
When a task exceeds its depth, Hadal files a structured escalation brief instead of bluffing. When it is unsure of an API, it emits a lookup request and the server fetches the official documentation before answering.
Built to pair with a stronger model
Hadal ships an MCP server, so a Claude Code session can delegate to it directly: draft, review, look up, or search the local knowledge base. Hadal handles the high-volume 80%; the expensive model concentrates on architecture and debugging.
Grounded in real documentation
The local index carries the full C# language reference — including every compiler-error page — plus .NET fundamentals and the diagnostics guides. Offline, lookups degrade gracefully to that local knowledge.
