Product / UX / UI & API

Grok

xAI's consumer chat product with a standalone app (grok.com) plus deep integration into X (Twitter), competing on real-time data access and a less-filtered tone. ~64M MAU by early 2026 and ~17.8% US chatbot share, third behind ChatGPT and Gemini, with the fastest single-year share gain of any consumer chatbot.

Grok consumer AI chat assistant by xAI, the app/UI surface (grok.com + X integration + mobile), live June 2026 (x.ai). Scored here as the chat-UI product, NOT the Grok 4.x model SKU (the model is scored in base_pretrained as Grok 4.20). Proprietary; human-in-the-loop assistant with image gen + X-grounded search.

Adoption

5 low confidence

5.0

App reported ~60-64M MAU and ~8-10M DAU early 2026, plus default availability to X Premium subscribers within X's ~350-400M MAU base. Clears >10M as a surface. Figures are aggregator-compiled (xAI does not publish a primary MAU page) and the X-embedded reach is hard to attribute cleanly, so low confidence on the exact number; reach band is robust.

Capability

4 high confidence

4.0

Capable general assistant UI with a unique real-time X-search edge; high feature breadth but single-provider-locked, so not the category frontier-definer. [verifier: Grok 4.1 features (real-time X-grounded search, multimodal, reasoning, free on grok.com/X/apps) confirmed via xAI's own release + X post; x.ai/news/grok-4-1 is live (403 to bot-fetch only). Capability evidence now primary.]
