Zsh Copilot
Zsh Copilot turns plain English into a shell command in your Zsh prompt with one Ctrl+Z press.
A minimal, honest plugin that does one thing: English in, command out, on your keypress. If your shell is already Zsh with zsh-autosuggestions, the install is a clone plus one line, and there is no subscription to justify. Pass if you use Bash or fish, or if you want completions running continuously rather than on a trigger.

Skip Zsh Copilot if you use Bash, fish or PowerShell, or if you want inline suggestions that appear as you type rather than waiting for a Ctrl+Z trigger.
Your own OpenAI or Anthropic bill is the real cost — the plugin is free but every Ctrl+Z suggestion is billed by whichever provider you point it at.
For a solo developer or sysadmin who already pays for an OpenAI or Anthropic key, Zsh Copilot adds no second bill and no per-seat charge — your cost is whatever that provider charges for the calls you trigger. Teams that need invoicing, admin controls or per-seat provisioning are looking at a different class of product than a single auditable Shell plugin.

What is Zsh Copilot?
Zsh Copilot — Zsh Copilot turns plain English into a shell command in your Zsh prompt with one Ctrl+Z press. Best for Zsh users who want a shell command drafted from English on a single keypress, Developers already running Oh My Zsh with zsh-autosuggestions installed, Sysadmins working inside SSH sessions who need command help without a GUI. Free to use.
Zsh Copilot is a small, MIT-licensed Zsh plugin that converts a plain-language description typed at your prompt into a ready-to-edit shell command. You write what you want in English, press Ctrl+Z, and the suggestion lands in your buffer. It is built for developers, sysadmins and Zsh power users who want a command suggestion on demand instead of a chat pane, a persistent CLI assistant or another subscription. The two installation paths are short. Oh My Zsh users clone the repo into $ZSH_CUSTOM/plugins/zsh-copilot and add it to the plugins array; everyone else clones to ~/.config/zsh-copilot and appends one source line for zsh-copilot.plugin.zsh to .zshrc. Three dependencies cover it: zsh-autosuggestions, jq and curl. Configuration lives entirely in environment variables. You supply an OpenAI key via OPENAI_API_KEY, which is the default provider, or an Anthropic key via ANTHROPIC_API_KEY. ZSH_COPILOT_AI_PROVIDER switches between openai and anthropic, ZSH_COPILOT_KEY rebinds the trigger from its ^z default, ZSH_COPILOT_SEND_CONTEXT (default true) decides whether shell context travels to the model, and ZSH_COPILOT_DEBUG toggles logging. Running zsh-copilot prints every option beside its current value. The codebase is 100% Shell and hosted on Gitea with a GitHub mirror, so you can read every line of what leaves your machine before you run it. Its closest comparison point is heavier CLI assistants that suggest continuously or bill monthly; this one stays quiet until invoked and charges you nothing beyond your own API usage. The catch is scope: Zsh only, no Bash or fish.

Behind the verdict
The design premise here is subtraction. Most AI terminal tools want to live inside your shell permanently, watching what you type. Zsh Copilot does the opposite: it wakes on Ctrl+Z, asks OpenAI or Anthropic for a command, drops it in your buffer, and goes back to sleep. The README essentially dares you to prefer it that way, and for a lot of people that is the right call. We would reach for it when you know roughly what you need but not the exact flags. Something like a find with the right predicates, a tar with the right exclusions, or a grep pipeline you would otherwise build by trial. One keypress and you have a draft to edit. In an SSH session with no GUI, that is a meaningful shortcut. Where it bites is the setup you own. You need an API key from OpenAI or Anthropic, and you pay that provider directly for usage. There is no admin console, no seat management, no usage dashboard. If your team expects centralized billing and controls, this is the wrong shape of tool. It also depends on zsh-autosuggestions, jq and curl already being in place. The honest limits: Zsh only. Bash, fish and PowerShell users are out of scope. The trigger is on-demand, not continuous, so anyone who wants suggestions streaming as they type will find it too quiet. And the project is small, with a migration in progress to the maintainer's own Git server, so expect the Gitea page to be the fresher of the two mirrors. The judgment call: pick it if you already live in Zsh and want a low-ceremony command generator with no subscription. Pass if you need cross-shell support, team billing, or always-on completions. In that last case a full CLI coding assistant is the closer fit.
Limitations
- Zsh Copilot requires an API key for either OpenAI or Anthropic to function, with inference billed by that provider on your own account.
- Suggestions are generated only when you press the trigger key (default Ctrl+Z), not as continuous inline completion.
- Shell context is sent to the model by default and must be disabled with ZSH_COPILOT_SEND_CONTEXT=false.
- It is a Zsh plugin requiring zsh-autosuggestions, jq and curl, and Oh My Zsh users must add it to their plugins array.

GeneratedReal-world workflow fit
Concrete scenarios for the personas Zsh Copilot actually fits — and what changes day-one when you adopt it.
You are on a remote box with no GUI and cannot remember the flag order for finding recently modified files. You type the intent in English at the prompt and press Ctrl+Z.
Outcome: A ready-to-edit command lands at your prompt without leaving the terminal or opening a browser.
You already run zsh-autosuggestions and have an OPENAI_API_KEY exported. You clone into $ZSH_CUSTOM/plugins/zsh-copilot, add zsh-copilot to your plugins array, and run zsh-copilot to confirm the options.
Outcome: Ctrl+Z generates commands on demand; your existing autosuggestions keep working alongside it.
You want to know exactly what leaves the machine and prefer Anthropic. You set ZSH_COPILOT_AI_PROVIDER="anthropic", export ANTHROPIC_API_KEY, and decide whether to keep ZSH_COPILOT_SEND_CONTEXT at true.
Outcome: Generation runs against your chosen provider, and you can read the 100% Shell source to verify the request path.
Use cases
- Generate a command to find all files modified in the last 7 days
- Ask for a one-liner to kill whatever process is holding a specific port
- Recall tar compression syntax without leaving the terminal
- Build a command that batch-renames files by pattern
- Construct a command inside an SSH session with no GUI available
- Switch the provider to Anthropic with one environment variable and keep the same Ctrl+Z workflow
Setup time & first value
How long it actually takes to get something useful out of Zsh Copilot — broken out by persona, not the marketing-page minute.
Oh My Zsh users: a git clone into $ZSH_CUSTOM/plugins plus one line in the plugins array, then export a provider API key — roughly ten minutes including dependency checks. Manual install: clone to ~/.config/zsh-copilot and append one source line to .zshrc. Run zsh-copilot to verify every option and its current value.
Switching to or from Zsh Copilot
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a browser chat window: stop alt-tabbing — press Ctrl+Z at the prompt and keep the generated command where you will run it.
- →From a continuous CLI assistant: install zsh-copilot alongside zsh-autosuggestions and keep completion continuous while generation stays on demand.
- →From OpenAI to Anthropic: set ZSH_COPILOT_AI_PROVIDER="anthropic" and export ANTHROPIC_API_KEY; the trigger and config surface stay the same.
- ↗To Bash or fish: unusable as-is — the plugin is Zsh-only, so you would need a different tool for those shells.
- ↗To a managed team product: if you need per-seat billing and admin controls, move to a platform that provisions keys centrally.
