Perplexity AI is what you get when you cross Google with ChatGPT and make it cite its sources. A service that has grown from a startup to a $9B valuation in two years and become the main competitor to Google Search in the research-first user segment. Let’s break down why you should use it.

How Perplexity Differs from ChatGPT and Google
A regular AI chat gives you an answer — and you have no idea where the information came from. Perplexity accompanies EVERY claim with a link to a source. This is a fundamentally different level of trust.
Google Search → a list of links, figure it out yourself
ChatGPT → an answer without sources, guess: truth or hallucination
Perplexity → an answer with inline citations, clickable links, and related questions
Perplexity doesn’t replace ChatGPT for creative tasks (write a poem, brainstorm a name), but for research tasks — it’s the best tool on the market.
Key Features
1. Pro Search (Deep Research)
The flagship feature. Instead of a single search query, Perplexity Pro Search performs multi-step research:
- Breaks down the question into sub-questions
- Searches each independently
- Compares and cross-references sources
- Produces a structured answer with sections and sources
Example: “Compare Cloudflare, Fastly, and KeyCDN pricing for a startup with 1TB traffic” → Perplexity visits the websites, collects prices, calculates total cost, shows a table.
2. Collections
Group conversations by project. Useful for:
- Competitive analysis (all competitor conversations in one collection)
- Academic research (thesis = one collection)
- Negotiation preparation (all partner information in one place)
3. File Upload
Upload a PDF, CSV, or image — Perplexity analyzes the content and answers questions about it. Useful for long documents, reports, and contracts.

Perplexity Affiliate Program
