InnerZero isn't a one-size-fits-all app. You can change how it looks, how the AI talks, what tools it uses, and how voice works. Here's a quick tour of what's customisable.

Five themes

Go to Settings > General > Theme and pick one:

  • Dark Zero. The default. Gold accents, teal secondary, deep blue-black backgrounds. This matches the innerzero.com website design.
  • Light Zero. The light variant. Same colour palette but with white and grey backgrounds. Easy on the eyes in well-lit rooms.
  • Classic Carbon. Orange accents on dark grey. If you like the old-school terminal aesthetic.
  • Soft Pink. Pink accent tones for something different. Same dark background.
  • Dark Teal. Teal accent tones instead of gold. Clean and cool.

Themes apply instantly. No restart needed.

AI personality

By default, Zero responds in a neutral, helpful tone. You can change that.

Go to Settings > Personality and pick a preset:

  • Professional. Formal, precise, structured responses. Good for work.
  • Friendly. Warm, casual, uses more natural language.
  • Concise. Brief, direct, no fluff. Gets to the point fast.

You can also create custom personalities with your own instructions. "Always respond in British English." "Use technical language for coding questions." "Be enthusiastic about cooking topics." Write whatever you want and Zero adapts.

Personalities apply to both text and voice conversations. You can enable multiple personalities at once. They blend together naturally.

Tool preferences

InnerZero has 30+ built-in tools. Maybe you don't want the AI using some of them. Go to Settings > Tools and toggle individual tools on or off.

Disabled tools are completely hidden from the AI. It won't try to use them or suggest them. If you never use the dictionary, turn it off. If you don't want screen reading, disable it. You're in control.

A "Reset to Defaults" button brings everything back if you change your mind.

Voice customisation

The voice system has several adjustable settings in Settings > Voice:

TTS voice. Choose from 14 local voice options. Each has a different tone and character. Try a few and pick the one you like.

Speed. Adjust how fast Zero speaks. Some people prefer faster delivery, others like it slower.

Audio mode. Headset mode for low-latency when using headphones. Speaker mode with echo suppression when using external speakers and a separate mic.

Silence threshold. How long Zero waits after you stop talking before it processes your speech. Lower values make it more responsive. Higher values give you more time to pause between sentences.

Input/output devices. Pick which microphone and speaker to use if you have multiple audio devices.

Output folder

InnerZero saves files (notes, downloads, generated content) to an output folder. By default, this is in your Documents. You can change it in Settings > General > Output Location.

You can also create a desktop shortcut to your output folder for quick access.

Active project

If you're working on multiple things, you can create projects and scope your conversations. When a project is active, Zero focuses its memory and file output on that project.

Switch projects in Settings > General > Active Project or from the project manager page.

Response format

Choose between formatted (Markdown rendered as rich text with headers, lists, and code blocks) or plain text (simple text with line breaks). Settings > General > Response Format.

Most people prefer formatted. But if you're copying responses frequently, plain text can be cleaner.

The point

InnerZero adapts to you. Your visual preferences, your communication style, your workflow. Change whatever you want, keep whatever you like. It's your AI.
