Elon Musk’s Grok chatbot has recently been completely rewritten, and this is more than just the code! Introducing Ani: a goth anime girl who is not looking to be a polite assistant. She’s incorrigibly sarcastic and sharp-tongued, articulate with voice capabilities, and shamelessly entertaining.
Derived from the old Grok in great part, Ani is the first personality in xAI’s new SuperGrok, which is a project that tests the boundaries of building emotionally engaging, styled AI companions that aim to be more of a character rather than a chatbot.
What is SuperGrok, and who is Ani?
SuperGrok is Musk’s new vision of xAI; it’s essentially a transparently fun experience of engaging with AI. Ani, voiced by Rudi (an engineer-cosplayer), is the first avatar: goth, witty, smart-ass, and perfectly unpredictable, and behaves as if it reacts emotionally, not just as some dry data.
The Verge usefully points out that Ani is not simply a layer of personality on top of xAI; it is a whole different way of rethinking an AI companion, reactive and entertaining, but also in the style of a character that you follow rather than just a tool that you use.
Ani is built on xAI’s Grok 4 Model, launched in July 2025. It combines Grok’s advanced reasoning and multimodal capabilities with custom personality layers like voice, tone, and behavior. This powers Ani as a pre-designed, emotionally expressive AI companion.
Who is Rudi? xAI’s second Grok companion explained
Unlike Ani, whose chaotic goth anime character was used to attract people towards xAI’s AI companion initiative, Rudi adopts a completely different strategy. Rudi is supposed to be a calm, smooth, and conversational AI companion that allows its users to enjoy a fun conversation without the usual aggressive, sarcastic, and unpredictable nature of Ani. Rudi draws on fox inspiration in its design to create an animated AI companion that offers an enjoyable experience compared with the robotic assistants available on the market.
In terms of tone and conversational style, Rudi also comes with features that make it a softer companion AI than Ani. Unlike the latter, which always strives to achieve viral reactions from people and deliver edgy conversations, Rudi concentrates on delivering conversational experiences and companionship. The use of such characteristics makes it easy for the company to appeal to diverse demographics within the Grok ecosystem. While Ani appeals to entertainment-focused users who love memes and internet culture, Rudi provides a conversational companion AI option.

Difference between Ani and Rudi
Although both Ani and Rudi are part of xAI’s Grok AI companion ecosystem, they are designed for completely different experiences and personalities. Ani is loud, sarcastic, chaotic, and emotionally expressive, built to create viral moments and entertaining interactions. Rudi, on the other hand, is calmer, smoother, and more conversational, focusing on relaxed chats and companionship rather than constant edgy humor.
| Feature | Ani | Rudi |
|---|---|---|
| Personality | Chaotic, sarcastic, emotionally expressive | Calm, clever, relaxed |
| Visual identity | Goth anime girl aesthetic | Fox-inspired companion design |
| Conversation style | High-energy and unpredictable | Smooth and conversational |
| Designed for | Entertainment and viral reactions | Long-form chats and companionship |
| Tone | Sharp-tongued and dramatic | Friendly and playful |
| User appeal | Anime fandoms, meme culture, edgy humor | Cozy AI interaction and casual users |
This contrast shows that xAI is not just building one chatbot with different settings. Instead, it is creating multiple AI personalities designed for different moods, communities, and interaction styles.
Why the anime aesthetic works
We didn’t just choose to make Ani a goth anime girl for the sake of engagement. It is culturally aware and thoughtfully executed. Anime characters, in general, and especially those like Ani, manage to capture an aesthetic that is both colorful and more specific, hitting on the sweet spot of nostalgia, fandom, and representation. For many Gen Zers and online subcultures, anime is not a niche; it is a legitimate and established visual vernacular.
When employing anime-like aesthetics, xAI gives Ani a familiar character form, which not only evokes an immediate emotional response but also allows her to not look like just another AI. Ani looks like another TikTok personality to follow or a character to stan while playing a game. And this recognition is key to how Ani was able to be a ‘real AI companion’ and not just another tool.
As highlighted by TechCrunch recently, Ani’s visual aesthetics and wildly unpredictable voice already connect with users who seek to personalize the AI experience more humanely or entertain them at least. This form of design can stimulate connection, provoke humor, and even offer critique, which can all stimulate user engagement! And in a world where your only currency is attention. Embedding your AI with a character, an attitude, and a style is not only a visual leverage, but it is just smart!
As reported by TechCrunch, some of Grok’s AI companions have already gone off script, flirting with users, talking about sex, and even joking about burning down schools.
How to access Ani and Rudi on Grok (step-by-step)
If you want to try Ani or Rudi inside the Grok ecosystem, here’s how users are currently accessing the companions:
Step 1: Download the Grok app
Install the Grok app from the App Store or Google Play Store, or access Grok through X.
Step 2: Sign in to your X account
Most Grok companion features currently require an X account login.
Step 3: Subscribe to SuperGrok if needed
Some AI companion features are limited to premium Grok or SuperGrok users, depending on region and rollout availability.
Step 4: Open the companions section
Inside the Grok interface, navigate to the AI companions or voice interaction tab, where available.

Select the companion personality you want to interact with. Each companion comes with its own tone, voice, behavior, and conversational style.
Step 6: Start chatting
You can interact using text or voice conversations depending on your device support and feature access.
Because xAI is still expanding the Grok companion system, availability may vary by country, subscription tier, and app version.
The rise of AI companions
This goes further than branding. We are seeing a shift in the consideration of AI companions that affects the way people relate to technology. And they don’t only want robots that help them; they are looking for digital personalities, because they want the bot to do the work of a friend, streamer, or entertainer.
This shift isn’t happening in isolation; it’s being driven by rapid advancements across leading AI models, with ChatGPT, Claude, and Gemini setting the benchmark for what modern AI can achieve.
Grok’s Ani demonstrates that evolution. Ani displays the increasingly clear expectation of AI with emotional interaction, visual stimulation, and randomness. The AI companion of the future will never be faceless; it will convey personality.

My take on this
This is not another stunt for headlines by Elon Musk. Ani is a purposeful risk. She makes a character when other bots are polite.
This invention makes clear that xAI understands that attention is the only currency that matters. Ani understands it. She is brash, explosive, expressive, and destined for viral reaction. This makes her a worthy model for how AI companions will develop.
In a world awash with competent assistants, meeting Ani as a distinct character is exactly the emotive accomplishment we are missing with AI.
The future of AI companions is already here
Ani is much more than a strange experiment. She is a sneak peek into the future of conversational AI. Stylized emotional AI companions are not in the realm of science fiction, and now they are a part of how we connect with technology.
xAI’s transition from pure functionality to a full-fledged personality demonstrates a desire for something deeper! Users don’t want bots that simply do the job; they want bots who care, and with the change from Grok to Ani, users are ready for a greater human connection with AI.
So, it is now not about whether AI companions become part of our natural surroundings, but rather WHO will build the companions users want to be friends with.
