The honest brief
Grok
Only major assistant with live access to the X firehose, plus a deliberately less-filtered voice.
- Real-time X/Twitter data
- Witty, direct persona
- Strong math/reasoning gains in recent versions
- Image generation built in
- Weaker at coding than rivals
- Smaller app/API ecosystem
- Concerns over bias and tone
- Limited voice mode
Perplexity
Pairs a consumer cited-answer engine with the Sonar API, so the same retrieval layer powers both.
- Inline citations on synthesized answers
- Cited search API for your own apps
- Pro lets you pick a model per query
- Strong on fresh, fact-based queries
- Citations can misattribute or be wrong
- Weak on niche topics with thin sources
- Best features gated behind Pro
