/learn @ARCANGEL0/NekoCLIREADME
AI assistant for your terminal, able to view, edit or generate images; create short videos; generate and save code/scripts; run commands and answer or assist with any subject.
NEKO is a lightweight, fast, and utility AI assistant for your terminal, to be acessible anytime you need.
It supports multiple flags and modes with a tidy formatted and colourful output in your terminal window such as persistent chat history, code mode, shell mode, video generation, image edition and creation, web search, vision mode and an optional pentest agent (beta).
ᗢ Features
- Fast & Lightweight – Minimal dependencies, instant startup with a single binary.
- Multiple Modes – AI chat with GPT5 + Web search and real time content, shell commands and execution, code generation, images and video generation, images analysis and editing, pentest mode with interactive and autonomous execution.
- Formatted output – Easy visualization data on terminal, outputs are displayed in colorful colorama boxes.
- Persistent History – Keeps context of chat if used with persistence flags. Chat history is saved in
~/neko/chat.jsonand pentest history in~/neko/pentest.json - Free endpoint – All the AI logic is run with my own API endpoint, alternatively ollama can be used for offline mode, change base api of *:11434 by editing the OLLAMA_BASE_URL.

⑇ Examples
$ neko -s "list all files sorted by size" # generates a command and asks user if he wants to Run it.
$ neko -c "Python script to merge two CSV files" # generates a short text and full python code, and asks user to copy code or save as a file in local dir.
$ neko -w "Latest CVE for OpenSSL in the last 2 months" # searches web for all possible index and findings on user prompt (CVE searches)
$ neko -a "Help me in a pentest process, to enumerate this IP 10.10.x.x and get a webshell" # neko will provide suggestions and commands to be run and ask authorization to run them, after running he will self collect the logs, analyze and suggest next steps and repeat the cycle.
$ neko -f /home/user/kitty.jpg "can you tell me the color of this cat?"
$ neko -g "Please generate an image of Donald trump vs Joe Biden in a MMA Octagon ring, both fighting" # Image generation with Neko
$ neko -gv "A video of a orange cat walking slowly in a cyberpunk city" # Video generation with Neko, usually a short video of 6 to 8 seconds.
$ neko -e /home/user/selfie.jpg "Please change the background and remove the people on it" # Neko will modify the image with AI and obey the request to remove people on background
$ neko -i "Tell me about Rutherford atom model" # after output, you will have option to ask a new question i.e: ''What about Schrodinger model?'' and continue conversation in context.
$ neko -wsl "find me a command to curl this endpoint with auth header" # combined short flags are supported (-w -s -l)
$ neko -x "i need help to enumerate 192.168.0.10 for open ports" # neko will return a small and a list of commands to be run by user, and ask them to retrieve the logs by calling command again, as in example below
$ cat nmapOutput.txt | neko -x "i have run nmap and found these info, what do you suggest now?" # Continues conversation saved on chat.json, analyzes nmap output and proceeds to suggest next steps
$ neko -r # resets all chat history.
$ neko --version # Outputs v6.7 🐈
| Not much to say, I just needed an interactive AI to speed up my workflow in terminals, and assist at pentesting or
coding and hitting Alt + Tab consistently to navigate through documentations, chatGPT for assistance,
among other things can be quite annoying.
And most repo's that offer similar solutions always require an OpenAI key, which I, as an Engineer Grad. student,
cannot afford because by tides of destiny, I was born poor.
So I decided to make my own CLI assistant using my own server for Free GPT 5-1 with
reasoning and vision capabilities without costs, making me able to
do all i need inside a single tty shell. 🐈
