AI research tools compared
Perplexity is built for research: it answers with citations, which makes it quick for market scans and fact-finding, but it isn't a general tool for drafting or code, and it bills in US dollars with no GST invoice. Its free Pro offer through Airtel is closed to new users.
ChatGPT, Claude and Gemini all do research too, with web search and long-document analysis; Claude is particularly strong on long reports and contracts. All three bill in rupees, ChatGPT and Gemini from ₹399 a month and Claude from ₹2,399.
Our take
Use Perplexity's free tier for quick, cited lookups and a general assistant for deeper analysis of documents you upload. Always click through to the sources: AI research tools still misquote figures and dates, and Indian regulatory details change often.
