Install cs.AI from Terminal in 60 seconds

csai is the Terminal CLI for cs.AI (chopsticksAI) — a full-screen agent in your shell, plus one-shot commands for scripts. You do not paste an OpenRouter or OpenAI key; live chat uses chopstickshq.com with the same free allowance as the Mac app and web agent.

One-line install

Requires Python 3.9+ (macOS and most Linux distros):

curl -fsSL https://chopstickshq.com/chopsticks-ai/install-csai-cli.sh | bash

Then run:

csai

Quick commands

csai ask "explain Swift actors in one paragraph"
csai ask "summarize this log line" --json
csai ask "hello" -q                    # reply text only
csai usage
csai update

Inside the interactive UI

/keys add <key> — unlock higher tiers (same as macOS/web)
/search on|off — toggle auto web search in chat
/login — chopstickshq.com account for synced allowance
/tier chopcode — set effort tier

Who this is for

Developers who want agent-style chat from SSH, a lightweight alternative to heavy IDE agents, or JSON output for shell scripts and CI notes. Not a local LLM — answers come from chopstickshq.com.
