Meta AI
- +Free and built into apps billions of people already use (WhatsApp, Instagram, Facebook, Messenger)
- +Genuinely multimodal for a consumer assistant: chat, image generation, and voice in one place
- +Hands-free use on Ray-Ban Meta smart glasses, plus personalization from Meta profile activity
- -An assistant, not an agent: it responds and generates when asked rather than completing multi-step tasks
- -Personalization draws on Facebook and Instagram activity, which raises privacy considerations
Perplexity
- +Citation-grounded answers are verifiable, a real advantage over uncited chatbots
- +Model flexibility: not locked to one LLM, with a proprietary search-tuned Sonar family plus frontier models
- +Genuine breadth from quick answers to research, deliverables, and agentic browsing in one product
- -The agentic features are supervised, not autonomous, and hallucination risk persists despite citations
- -Tier proliferation with the best features gated behind paid or US-only access
