Perplexity
Perplexity is the best AI tool for research — every answer comes with clickable citations, and the free tier is genuinely useful.
Perplexity's core strength is research: it searches the live web and returns an answer with clickable citations instead of an unsourced wall of text.
Answers are generally accurate and well-organized, with quality that tracks the reliability of the sources it finds for a given query.
The search-bar-style interface is instantly familiar and has essentially no learning curve.
The free tier is genuinely useful for daily research; Pro at $20/mo raises the daily cap on premium searches and unlocks model choice.
It's optimized for research and Q&A rather than long-form creative writing, and even Pro has a daily cap on premium searches.
