What it does

Nate says Perplexity is less central to his personal day-to-day than it once was, but it remains useful when agents or automations need research. In his stack framing, this places Perplexity near Perplexity API: a research capability that becomes valuable when embedded in a concrete workflow rather than treated as another open-ended chat destination ^[src-053].
