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
Pricing signal: Free access is available. Perplexity Pro starts around $20/month, or about $17/month with annual billing. Max and Enterprise tiers are higher and vary by plan, seat count, and billing term.
Use cases: market research, competitor scan, source gathering, topic exploration
