Features
Perplexity: Perplexity's web search and reasoning, built-in citation tracking and multimodal support make it production-ready for knowledge work without custom prompt engineering.
Cohere: Cohere's command-line and API let you fine-tune on domain data, control output format and integrate with your data pipeline—more plumbing, more control.
Pricing
Perplexity: Perplexity's consumer-friendly pricing and generous free tier make it attractive for individuals and small teams exploring AI—no per-API-call meters.
Cohere: Cohere charges per API call and per-token, scaling with usage but predictable for fixed-throughput workloads if you commit.
Ease of Use
Perplexity: Perplexity's chat interface requires zero technical setup—type a question, read the answer, inspect citations. Non-technical users ship value immediately.

Integrations
