Frequently Asked Questions
Find answers to the most common questions about Companion.
How do I install Companion?
Companion is currently in beta. Anyone can download and try it immediately. Visit our download page, install the application, and start automating your workflows right away. Note: Windows may show a security warning during installation since we don't have an EV certificate yet - this is normal and safe to proceed.
Is Companion compatible with my operating system?
Companion works on Windows 10, Windows 11, and macOS (Apple Silicon and Intel). Linux support isn't available yet.
Does Companion require an internet connection?
Yes, Companion requires an internet connection to function. While it runs on your local machine and controls your applications directly, it uses online AI models for processing and decision-making.
Is my data secure?
Yes. Companion runs on your local machine with full control over what data is shared. Your API keys are encrypted with AES-256 on disk and only sent per-request over encrypted connections — never stored or logged on our servers. Your files, emails, and personal information stay on your machine unless you explicitly choose to share specific data for a task.
What applications does Companion integrate with?
Companion integrates with 100+ applications including Google Workspace, Microsoft Office, Slack, Notion, and many more via MCP. You can find the full list of integrations in our documentation.
How much does Companion cost?
Companion is completely free — no subscriptions, no tiers, no credits to buy. You bring your own OpenRouter API key and pay OpenRouter directly for AI model usage, typically $2-15 per million tokens depending on the model you choose. Visit our pricing section on the main page for details.
Can I switch AI models at any time?
Yes. Companion ships with 11+ curated models from Anthropic, OpenAI, Google, xAI, and open-source providers, plus any custom OpenRouter model ID. Switch models mid-conversation whenever you want — there's no plan to upgrade or downgrade, just your OpenRouter key and usage.
How do I update Companion to the latest version?
Companion automatically updates to the latest version when you launch the application. Updates are required to ensure you have the latest features and security improvements.
