PhengosLocal-first AI, on your terms

A bring-your-own-key AI workflow tool. Generate, organize, and verify model output — while your API keys stay in your OS credential store and your requests go straight to the provider.

Getting Started

🔑

Bring your own key

Use your own Anthropic, OpenAI, or Mistral keys. They're stored in your operating system's secure credential store — never in plain config, never sent anywhere but the provider.

Workflows & profiles

Separate "who the model is" from "what it's working on." Compose reusable roles and conventions into every run instead of re-writing prompts.

Learn the system

🗂️

Projects, sessions & history

Every run is saved per project with its prompt, response, and generated files — organized into sessions you can revisit and reuse.

How it's organized

🛡️

Tamper-evident runs

In the Full edition, each saved run carries an integrity record so you can verify it hasn't been altered after the fact.

Local models via Ollama
