Perplexity AI

Research

Best for: Market research, Competitor research, Fast answer gathering, Source-backed exploration
Strengths: Strong research workflow, Helpful for finding sources, Fast for discovery work
Tradeoffs: Less suited to polished creative output, Local compute needs qualifying hardware: Mac Hybrid Compute has a 24GB unified-memory minimum, while fully local Mac recommends at least 36GB; Portable Computer has separate NVIDIA requirements, Cloud, hybrid and local are different data paths; authorizing web, connector or frontier-model escalation can still send task data to external services
