Grok
xAI
Best for: AI Assistant for people who want a checked, free option.
Grok is xAI's assistant, usable at grok.com and inside the X app. Its distinguishing feature is live access to X posts — questions about anything happening now get answers grounded in what people are posting this minute, not a stale training cutoff.
The free tier at grok.com includes web and X search, voice mode, and connectors with daily usage caps. SuperGrok ($30/month) adds the newest Grok 4.7 model, multi-agent reasoning, image and video generation, and higher limits; a Plus tier ($100/month) brings priority access.
It fits people who want an assistant with a pulse on social media — journalists, traders, and anyone following fast-moving events — plus developers watching xAI's model releases.
To begin, open grok.com and ask about something that happened today; the real-time sourcing is the part no other free assistant matches this directly.
The honest limits. Free usage caps are soft and unspecified — heavy sessions will hit them without warning. X posts are a noisy source; verify anything that matters. Model quality claims come from xAI's own benchmarks. Not used first-hand; confirm at x.ai/grok and x.ai/pricing.
