Perplexity

Perplexity answers questions with cited sources rather than a single unattributed response, which makes it useful for trend forecasting, competitor scans, and fact-checking claims before they go into a brand deck or press release. Fashion researchers use it to quickly pull together a snapshot of what's being written about a color trend, fabric innovation, or competitor launch, then follow the citations for deeper reading. Its focused search mode narrows results to recent sources, helpful for fast-moving trend cycles. It's not a writing or generation tool — most teams use it upstream of ChatGPT or Claude, feeding synthesized research into the actual copy or strategy work.
