Build an AI CLI Assistant in 15 Lines of Python

Pipe anything to AI from your terminal. Answer questions, summarize logs, explain errors — without leaving the command line.

Ever wished you could ask AI a question without opening a browser?

$ ai "How do I find large files in Linux?"
→ du -ah / | sort -rh | head -20

Here's how to build it in 15 lines.

The Script

#!/usr/bin/env python3
import sys, os
from openai import OpenAI

client = OpenAI(
    api_key=os.getenv("AIBRIDGE_KEY"),
    base_url="https://aibridge-api.com/v1"
)

prompt = " ".join(sys.argv[1:]) or sys.stdin.read()

response = client.chat.completions.create(
    model="deepseek-v4-flash",
    messages=[{"role": "user", "content": prompt}],
    stream=True
)

for chunk in response:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="")

Usage

#Ask questions
$ ai "explain this error: SyntaxError: invalid syntax"

#Summarize logs
$ cat error.log | ai "summarize these errors"

#Generate code
$ ai "write a bash script to backup my home directory"

#Explain code
$ cat app.py | ai "what does this file do?"
