Wordcab has collaborated with Knowledgator and SCX.ai for the release of the new guardrails model family: Opir.ai
Docs/CLI/Installation

Installation

Four supported install paths. All yield the same binary and the same signed provenance.

Package availability

Wordcab SDKs, CLI tools, Helm charts, model weights, and deployment packages are delivered directly to each customer for self-hosted installation. They are not publicly published package-manager artifacts, so install commands in these docs are placeholders until your Wordcab team provides your private package source or offline bundle.

Homebrew (macOS / Linux)

bash
brew install wordcab/tap/wordcab
wordcab --version

npm (any platform with Node 18+)

bash
npm install -g @wordcab/cli
wordcab --version

Static binary

Download the release that matches your platform from github.com/wordcab/cli/releases. Binaries are Cosign-signed; the public key is published on the repo.

bash
# Linux x86_64 example
curl -L -o wordcab \\
  https://github.com/wordcab/cli/releases/latest/download/wordcab-linux-amd64
chmod +x wordcab
sudo mv wordcab /usr/local/bin/

# Verify signature
cosign verify-blob \\
  --key https://github.com/wordcab/cli/releases/latest/download/cosign.pub \\
  --signature wordcab.sig \\
  wordcab

Docker / CI image

bash
docker run --rm -it \\
  -e WORDCAB_API_KEY \\
  -v $PWD:/work \\
  ghcr.io/wordcab/cli:latest \\
  transcribe /work/call.wav --model qwen3-asr

Airgapped install

The signed binary, SHA sums, and Cosign signature are bundled with every Wordcab offline bundle. Extract and place on PATH; no internet connectivity is required.

bash
tar xzf wordcab-offline-v1.8.0.tar.gz
sudo install -m 0755 wordcab /usr/local/bin/wordcab
wordcab --version

Shell completion

bash
# bash
wordcab completion bash > /etc/bash_completion.d/wordcab

# zsh
wordcab completion zsh > "${fpath[1]}/_wordcab"

# fish
wordcab completion fish > ~/.config/fish/completions/wordcab.fish

Upgrade

bash

npm install -g @wordcab/cli@latest # npm
wordcab self-update                # static binary: replaces itself, verifying the signature
