🤔 Perplexity AI Kya Hai?
Perplexity AI 2022 mein Aravind Srinivas (Indian-origin founder, ex-OpenAI researcher) ne start kiya tha — IIT Madras se grad. Aaj yeh fastest-growing 'answer engine' hai jo ChatGPT-style conversational interface ke saath Google-style real-time web search combine karta hai. Har answer ke saath sources/citations link karta hai (1, 2, 3, 4 hyperlinks), jo academic research, journalism, fact-checking ke liye crucial hai. Pricing — free tier mein 5 Pro searches/day + unlimited basic searches, Perplexity Pro $20/month (~₹1700) ya yearly ~₹17,000.
Kya unique hai? Char cheezein. Pehla — sources har answer mein clickable hain, yani aap verify kar sakte ho ki AI hallucinate nahi kar raha. Doosra — Pro plan mein aap choose karte ho konsa underlying model use kare — GPT-4, Claude, Gemini, Grok, Sonar (Perplexity ka own model). Teesra — 'Focus' modes hain — Web, Academic, YouTube, Reddit, Wolfram — taaki search narrow ho. Chautha — 'Spaces' feature jo aapke uploaded files (PDFs, docs) + web ek saath search karta hai. Aravind ke Indian roots ki vajah se Perplexity ka India focus strong hai — Airtel ne Perplexity Pro 1-year FREE deal nikala tha 2024-25 mein Indian users ke liye (60M+ users got it). Mobile apps iOS/Android dono pe excellent.
