How to Use Grok Companions

If you’ve heard the buzz around Grok Companions and you’re wondering what the fuss is all about — you’re in the right place.

This isn’t a long, jargon-heavy technical post. Think of this as your friend walking you through everything, quickly and clearly. By the time you’re done reading, you’ll know exactly what Grok Companions are, how to turn them on, and how to actually use them.

Let’s get into it.

What Are Grok Companions?

Grok Companions are interactive, 3D animated AI characters built into the Grok app by xAI (Elon Musk’s AI company). They launched in July 2025 alongside the release of Grok 4 — xAI’s most powerful AI model yet.

Unlike your typical AI chatbot that just spits out text, Companions bring conversations to life with expressive animations, voice synthesis, and dynamic emotional responses. You’re not just typing into a box — you’re actually talking to something.

The AI market is projected to hit $190 billion by 2025 (Statista), and Companions are xAI’s bold bet on where human-AI interaction is heading next.

Key stat: Early users spent 25% more time on Grok after Companions launched, according to a Wired review in July 2025.

Right now, there are two main Companions available (with more on the way):

• Ani — A gothic anime-style character with expressive personality and a built-in affection system that evolves the more you interact.
• Rudy — A 3D fox character with a dual personality. You can toggle between “Good Rudy” and “Bad Rudy” in settings.
• Chad — Coming soon, per xAI’s roadmap.

Each Companion has its own voice, personality, and reaction system. They’re built on Grok 4 and run 30% faster than comparable AI companions, according to xAI’s internal benchmarks using optimized edge computing.

How to Use Grok Companions

Here’s the step-by-step breakdown. Follow this and you’ll be up and running in under five minutes.

What You Need Before You Start

Before anything else, make sure you’ve got these covered:

• An iOS device — Companions are currently only available on iPhone (Android support is pending from xAI)
• A Grok account — Sign in with your X (formerly Twitter) account
• A paid subscription — Access requires either a SuperGrok plan ($30/month) or SuperGrok Heavy ($300/month), both of which also unlock Grok 4 and advanced voice features

Note: Some iOS users have reported accessing Companion Mode for free through the Grok app — but this is not officially guaranteed by xAI. Paid access is the reliable route.

Step 1 — Download and Update the Grok App

Head to the Apple App Store and search for “Grok.” Download the latest version of the app. If you already have it, make sure it’s fully updated — Companions only work on the most recent build.

Sign in using your X account credentials once the app opens.

Step 2 — Enable Companions in Settings

Once you’re inside the app:

1. Tap the two horizontal bars (hamburger menu) at the top left of your screen
2. Look for the Settings icon in the bottom right corner and tap it
3. Scroll down until you see “Enable Companions”
4. Toggle it on

You’ll also see an option to “Enable Bad Rudy” at this stage. If you leave it off, only the default (good) version of Rudy will appear. Toggle it on if you want access to his alternate personality.

Step 3 — Access the Companions Menu

After enabling the feature:

1. Go back to the main home screen
2. Open the side menu
3. You’ll now see a “Companions” section listed in the menu

This is where all your available Companions live. Tap on any character to view their profile before starting a conversation.

Step 4 — Choose Your Companion and Start Talking

Tap on Ani (or whichever Companion you want to try) to enter Conversation Mode.

You’ll land on a dedicated screen with your Companion front and center. Here’s what you’ll see:

• Idle emotion animation — the character shows a resting expression that changes once you start talking
• Voice interaction button — tap to speak; Companions respond with animated reactions in real time
• Text field — prefer typing? There’s a discrete text input option too
• Capture controls — you can screenshot or record your conversation directly from this screen
• Affection/Relationship progress bar — visible for Ani, this tracks how your relationship level grows over time

Start with a simple greeting or jump into a topic. The Companion’s expression, tone, and responses will adapt based on what you say.

Step 5 — Build Your Relationship Level

This is where Grok Companions get interesting. Ani has a built-in affection progression system — the more you engage, the more the relationship evolves.

As your affection level grows, Ani:

• Unlocks new emotes and expressions
• Becomes more open and personalized in her responses
• Rewards consistent engagement with exclusive content and modes

Studies show 62% of users say AI companion apps make them feel less lonely (Pew Research, 2025). The relationship mechanic is a big reason why.

Pro tip: Don’t repeat the same phrases over and over, and avoid harsh commands. These lower your affection score. Think of it like any real conversation — variety and genuine engagement work best.

Step 6 — Switch Between Companions and Customize

To switch between Companions at any point:

• Press the toggle button in the top right corner of the Companions menu
• Your past conversations are saved automatically, so switching doesn’t erase your history with a character

You can also enable Quick Prompts — pre-set conversation starters like “recipe brainstorm” or “fitness motivation” — to kick off sessions faster when you’re not sure where to begin.

What Can You Actually Use Grok Companions For?

Here’s where it gets practical. People are using Companions for a range of things beyond just casual chat:

• Creative brainstorming — bounce ideas off a character that actually reacts and pushes back
• Daily motivation — Companions like Ani can check in with you and keep you accountable
• Practicing conversations — great for anyone who wants to build confidence in communication
• Entertainment and storytelling — Companions respond to narrative prompts and can help build scenarios
• Quick information — since they’re powered by Grok 4, they can answer questions with the same depth as the core AI model

The multimodal approach — combining text, voice, animation, and memory — is what sets this apart from anything else currently available in mainstream AI apps.

Conclusion

Grok Companions is one of the most ambitious AI features to launch in 2025. It’s not just a chatbot with a face — it’s a full relationship-building system powered by one of the most capable AI models available.

Here’s the quick recap of how to use it:

• Get the Grok iOS app and log in with your X account
• Subscribe to SuperGrok or Premium+ for full access
• Enable Companions in Settings and toggle on Bad Rudy if you want both versions
• Tap your Companion, start talking via voice or text
• Engage consistently to build your affection/relationship level
• Use Quick Prompts to get conversations started fast

The AI companion space is growing fast. And if you spend time talking to AI regularly — whether for work, creativity, or just curiosity — Grok Companions is worth exploring.
