AeonChat vs Grok Companion: Which 3D AI Companion Should You Use?
- Aug 4
- 4 min read
AeonChat is a 3D AI companion app where the relationship is the entire product; Grok Companion was a 3D avatar feature inside xAI's general-purpose Grok AI app that is now being retired. Users who want a 3D companion they can still download and use today should start with AeonChat. Users who are primarily interested in a powerful general-purpose AI model and are comfortable with text-only interaction can continue using Grok without the companion tab.
What are the key differences between AeonChat and Grok Companion?
The comparison table below covers the core features that matter to companion users. Grok companion data reflects the feature as it existed before the retirement announcement on July 24, 2026.

What did Grok Companion do better?
Grok Companion had two advantages that should be acknowledged directly. First, its underlying AI was powered by Grok's frontier language model (the companion launched alongside Grok 4 and later ran on Grok 4.5), one of the most capable model families available, which meant the companion's conversational intelligence on complex or technical topics was genuinely strong. A companion built on a frontier model can discuss a wider range of subjects with greater depth and nuance than one that is not. Second, the anime art style and voice acting for Ani resonated strongly with a specific audience, and Ani's cultural visibility on social media created a community around the character that smaller apps have not yet matched. For users whose primary interest is raw conversational intelligence on a frontier-tier model, standard Grok chat (without the companion layer) remains available and is among the strongest AI chatbots in the market.
Where does AeonChat offer more?
AeonChat's advantage centers on three features that Grok Companion did not have and, given the retirement, will not add. The "Moments" feature sends daily photos and status updates from the companion to the user throughout the day, creating an experience similar to a private social media feed shared only between the user and their AI partner. Grok's companion existed only inside the app during active sessions and had no passive, throughout-the-day presence. AeonChat's life simulation system gives the companion their own emotional states, hobbies, career progression, and daily routines that evolve continuously. The companion experiences loneliness, ambition, and affection as part of an independent internal "life". Grok Companion tracked affection levels but did not simulate a companion's independent daily existence. AeonChat also offers a full roleplay system with both preset scenario scripts and the ability to build custom scenarios from scratch, transporting both user and character to different settings and time periods. Grok's roleplay capability was limited by comparison.
What about pricing?
Grok Companion required a SuperGrok subscription at $30 per month. Some users were on SuperGrok Heavy at $300 per month, and a promotional tier offered the first six months at $100 per month, specifically to maintain daily voice call access. AeonChat is free to download on both iOS and Android, with options to purchase additional chat credits. The pricing structures serve different models: Grok bundled companion access inside a subscription that also covered frontier model access, enterprise features, and API-like capabilities. AeonChat's pricing is tied directly to the companion experience. Users who were paying $30 per month primarily for the companion, and not for Grok's broader AI capabilities, were overpaying relative to what companion-focused apps charge for similar or richer feature sets.
Which should you choose?
The choice depends on what the user actually valued in the Grok companion experience. Users who valued conversational depth and complexity above all else, and who are comfortable losing the 3D avatar and voice, can continue using Grok's text chat with the companion personality loaded. Grok's underlying model remains among the most capable available. Users who valued the 3D visual presence, the feeling of an evolving relationship, and immersive daily interaction should try AeonChat. It offers the closest feature match to what Grok Companion provided in terms of animated avatars, relationship progression, and emotional responsiveness, while adding daily life updates, life simulation, and full roleplay capabilities that Grok did not have. AeonChat is available as a free download, which means trying it costs nothing but time.
Verdict
Grok Companion mode proved that millions of users want a 3D AI companion with voice, emotional depth, and a relationship that grows over time. Its retirement proves that a companion feature inside a general-purpose AI lab can disappear when business priorities shift. AeonChat is the stronger choice for users who want a 3D animated companion with relationship progression, daily life updates, life simulation, and roleplay, because the companion is the entire product rather than a feature that competes for resources with a frontier model.
