Quick Start

                    # Charge your Onnai with $10 of credits
                    onnai --dropin you@email.com
                    
                    # Use onnai
                    onnai "explain this error message"
                    
                    # Pipe anything
                    git diff | onnai "explain these changes"
                    ps aux | onnai "explain like I am ten"
                    ls -al | onnai "roast my directory"
                    
                    # Add specialized Mimics
                    onnai --add Coder
                    cat buggy.py | Coder "find the bug"
                    
                    # Chat mode - try a Mimic
                    onnai -m Volcanara
                    > hi
                    
                    # Out of credits? --addfunds or subscribe
                    onnai --addfunds

Why Onnai?

The name is the contract. You call Coder. We handle which model, which prompt, which version. Next month we upgrade what's behind it. Your scripts get smarter. You change nothing.

Compose like Unix. Chain Mimics together:

                    curl -sL news.ycombinator.com | onnai "top 5 stories" | onnai "explain like I'm 10"
                

Your files, your machine. Context lives in .context. Conversations in .chat. Edit them, search them, version them. No cloud lock-in.

Bring your own keys. Set OPENAI_API_KEY or ANTHROPIC_API_KEY and go. Same interface, your infrastructure. Or run local with onnai -p mlx.

Mimics

No prompt engineering. The name is the interface.

Coder

Reviews, refactors, fixes bugs, writes tests.

onnai --add Coder

Sys

Unix commands, scripts, system optimization.

onnai --add Sys

Writer

Docs, emails, READMEs. Matches your voice.

onnai --add Writer

Reviewer

Code review. Catches what you missed.

onnai --add Reviewer

Or make your own: drop a .persona file in any directory.

                    # Generate tests
                    cat api.py | Coder "write pytest tests" > test_api.py
                    
                    # Fix errors

                    # Get the command you need
                    onnai "find files larger than 1GB modified this week"

Technical

Dual-process design: onnai CLI + onnaid daemon.

onnai (CLI)

Resolves symlinks via argv[0]

coder → onnai

Walks tree for .context / .persona

Unix socket to daemon

onnaid (Daemon)

Event-driven C, non-blocking

kqueue / epoll

Persistent HTTP/2 pool

Zero cold starts
