Frequently Asked Questions
If you have a question that isn't here, open an issue on GitHub.
Do I need to pay anything?
Axon Terminal is free for non-commercial use. To use it you need a Claude Code subscription from Anthropic, which is paid. Axon Terminal does not charge you anything separately.
What operating systems does it support?
Currently only Windows 10 or later (64-bit). Linux and macOS versions are in development.
Can I use it offline?
No. Axon Terminal needs an internet connection to communicate with Anthropic servers. Without a connection, Claude cannot respond.
Are my conversations private?
Yes. Axon Terminal does not store or have access to your conversations. Everything goes directly between your machine and Anthropic servers. The app has anonymous telemetry, but it is disabled by default and only activates if you choose to in Settings. Secrets (API keys) are encrypted locally with AES-256-GCM and never transmitted.
What models can I use?
Sonnet 4.6 (fast and balanced for daily use), Opus 4.6 with 1M context (the most powerful, for complex tasks), and Haiku 4.5 (the cheapest, for simple tasks). You can switch models anytime with /model. You can also connect your own OpenRouter API key to use alternative models.
How do I change the voice?
In Settings > Voice. There are 8 neural voices in Spanish from different countries: Elvira and Alvaro (Spain), Dalia and Jorge (Mexico), Elena and Tomas (Argentina), Salome and Catalina (Colombia).
Can I create my own themes?
Yes. In Settings > Appearance there is a visual theme editor with 16 CSS color variables. You can create yours from scratch or modify an existing one. Themes can be exported as a file and imported into another installation.
What is worktree mode?
In worktree mode, Claude works on an isolated copy of your project instead of editing your files directly. When done, you see all changes in a diff and decide whether to apply or discard them. Useful when you don't want Claude touching your code until you've reviewed what it did.
Can I go back if Claude breaks something?
Yes. Press Esc twice to open the checkpoint dialog. Every turn in the conversation is a restore point. You can recover just the conversation, just the code, or both to any previous turn.
How do I report a bug?
Use the /bug command inside the app. It opens an issue directly on GitHub with session context included. You can also go to the GitHub repository manually.
Does it have a built-in terminal?
Yes. Since version 0.99.0, Axon Terminal includes a real terminal with PTY (PowerShell, CMD, or PowerShell Core). Open it with Ctrl+` without leaving the app. If the terminal crashes, it reconnects automatically.
What is Zen Mode?
Zen Mode hides the entire UI except the conversation, for when you need to focus. Activate it with Ctrl+Shift+Z. The UI reappears automatically when Claude needs your attention.
