Show HN: AI-CLI – tiny C terminal assistant powered by local LLM

A developer released AI-CLI, a tiny C terminal assistant that connects user requests to a local LLM and executes returned shell commands directly. The tool supports multiple platforms and LLM engines, allowing users to accept, edit, or reject actions before execution. The authors warn that the tool can cause damage if used carelessly.

command line assistant smoothly connecting your requests with LLM of your choice and executing directly returned actions, all in a single C file Free yourself from writing all those complex actions in command line shell, instead ai assistant will do it for you based on your requests. Your choices are: accept actions by just pressing Enter with opportunity to edit assistan's answer first or reject actions by pressing Ctrl+C . If for example, you want to know who did run jobs on a particular Slurm node, you may ask: $ ./ai who was running jobs on a slurm node 39 between 1 and 2 hours ago user847 uset20499 The action assitant returned might look like: sacct --format="JobID,JobName,User,NodeList,Start,End,State" --allusers --starttime=$ date -d "-2 hours" "+%Y-%m-%dT%H:%M:%S" --endtime=$ date -d "-1 hours" "+%Y-%m-%dT%H:%M:%S" --allocations --node=39 | tail -n +3 | awk '{print $3}' | sort | uniq Other examples: $ ./ai replace Solar with solar in every python file in this folder Done $ ./ai modify permissions of this folder so no other user can read anything here Done $ ./ai find all occurances of subword "perform" in words.txt and print their line numbers 1881 10046 10047 40358 $ ./ai math log of 4096 8.317766166719343 $ ./ai show me last 3 lines in each c file in current folder buffer free &original ; return exit code; } $ ./ai what is IP address of somewebsite xxx.xx.xx.xxx Be careful, because this tool executes actions returned by LLM directly in your shell. Authors are not responsible for any damage this program can cause. If you are not familiar with shell commands, do not use this assistant. sh run.build ai.sh or directly gcc ai.c -o ai This will copy ai into your ~/.local/bin and man page into ~/.local/share/man/man1/ sh run.build ai.sh You can build and run this tool on literally any platform, fully supported: - Linux - macOS - Android - FreeBSD - iOS - OpenBSD - NetBSD - QNX Neutrino - Windows MSYS2 or Cygwin - WebOS - Haiku - SerenityOS - DragonFly BSD - illumos - Solaris - AIX - HP-UX - Tru64 UNIX - IRIX - UnixWare - SCO OpenServer - Redox OS - VxWorks - RTEMS - INTEGRITY Most LLM engines are fully supported: | Engine | /v1/chat/completions | |---|---| | llama.cpp | Yes | | vLLM | Yes | | TensorRT-LLM | Yes | | Ollama | Yes | | LM Studio | Yes | | SGLang | Yes | | Text Generation Inference TGI | Yes | | Aphrodite Engine | Yes | | LocalAI | Yes | | Xinference | Yes | | FastChat | Yes | | MLC LLM | Yes | | KoboldCpp | Partial | You need an LLM engine running locally or remotely. Example how you may run llama.cpp with Gemma-4 model: llama-server --host 0.0.0.0 \ --model unsloth/gemma-4-12B-it-qat-UD-Q4 K XL.gguf \ --temp 1.0 \ --top-p 0.95 \ --top-k 64 \ --port 8001 \ --chat-template-kwargs '{"enable thinking":false}' Remember to disable thinking mode - answers model provides will be direct shell actions. bash $ export AI URL="http://127.0.0.1:8001" $ ./ai which file in this folder is to build ai tool ./run.build ai.sh You can accept answer by pressing Enter and actions will be executed in shell or you can press Ctrl+C to reject entire actions. You can edit returned answer just like in any editor - use arrow keys to navigate. To execute actions place cursor to the end of the entire answer and press Enter or reject at any time by pressing Ctrl+C. You can enable assistant's memory with --memory flag, in this case it will update AI MEMORY.md in the current directory. This helps solving more complex tasks, assistant will remember all previous actions including rejected. $ ./ai --memory what operating system do I have MINGW64 NT-11.0-12345 $ ./ai --memory but it says MINGW...bla bla, I dont know such OS You are running Windows, but you are using the MINGW64 environment a common way to run Linux-like tools on Windows .
