It depends on your research volume. Pro unlocks multi-step reasoning and file uploads, but casual researchers may find the free tiers of Google Gemini or ChatGPT sufficient. Power researchers who need cited answers daily will get the most value.
Google Gemini’s free tier offers AI-powered search with Google’s index behind it. Microsoft Copilot also provides free web-grounded answers with source citations. Both are strong options for casual research without a subscription.
Perplexity links to real sources, but accuracy depends on source quality. It sometimes cites content farms or low-authority pages. Always click through to verify — cited doesn’t mean correct. Google Gemini and ChatGPT face similar challenges.
