Perplexity
Perplexity
Fast lookups with sources to verify; less suited to drafting long documents.
An AI search engine that answers directly with cited sources you can verify; well suited to quick market research.
Overview
Perplexity is an AI-powered search engine: you ask a question, Perplexity searches the web in real time and replies with a synthesized answer, along with citations and links to the sources so you can check them yourself.
Instead of opening dozens of Google tabs, a business owner can ask directly about competitors, price trends, new regulations or suppliers and get a concise, sourced answer. Perplexity offers regular search plus Pro Search and Research modes for questions that need more depth, and paid plans let you pick AI models from OpenAI or Anthropic.
Perplexity also has Spaces for gathering documents and searches by topic, features for creating files and apps (spreadsheets, dashboards, slides), and Enterprise plans that commit to not using your data for training.

Real-world example
A water-filter distributor in Can Tho is preparing to expand into air purifiers. The sales manager uses Perplexity to ask about consumer trends, brands already on the market and relevant import regulations, then opens each cited source to verify and saves everything in a shared Space for the board to review before the meeting.
Tips & notes
Always open the cited sources
A synthesized answer can misinterpret; the original source is the reliable basis.
Ask follow-up questions
Continue in the same conversation to go deeper rather than starting over.
Prefer authoritative sources
Ask Perplexity to prioritize government sites and reputable news when looking up regulations.
Use Research for big decisions
For important topics, use deep research mode rather than quick search.
