Grammarly vs Perplexity: One Fixes Your Sentence, the Other Checks Your Fact

These get compared because both sit in your writing flow. They solve different halves and confusing them is how a clean sentence states something false.

Grammarly makes the sentence correct and pleasant. Perplexity makes the claim true, by showing you the source. A grammatically perfect sentence with an invented stat is worse than a clumsy true one.

My rule: Grammarly on the way out, Perplexity on the way in. I check a fact before it's polished, because a fluent lie is the hardest error to catch once it reads well.

Keep both. Grammarly for the words, Perplexity for the world. The mistake is using one as the other, which is how confident nonsense gets published and cited.
