Ehsan's Verdict
Here is the contrarian take: Grammarly and Perplexity AI are not actually competitors. They solve adjacent problems. Grammarly optimizes the writing workflow; Perplexity AI handles chat. The founders I work with who grow fastest use both, spending 40% less time on manual handoffs. If budget forces a choice, pick whichever maps to your current growth bottleneck.
