Read the full Grammarly review

Grammarly is the writing assistant most professionals already have installed. Beyond grammar, its tone detection, rewrite suggestions and generative features help you sound clearer and more consistent across email, docs and browser writing. It is not a replacement for a chatbot, but it is the safety net that catches what a chatbot writes on your behalf.

Read the full Perplexity review

Perplexity is the AI you use when you would normally open five browser tabs. It combines large language models with live web search to return a written answer that cites its sources inline — so you can verify claims quickly instead of trusting a black box. Pro Search plans queries into multiple steps for deeper questions, Spaces keep research organized across a topic, and Focus modes narrow searches to academic papers, YouTube or Reddit. It is not a replacement for a general-purpose chatbot, but for time-sensitive research it is the fastest tool in the category.
