Ehsan's Verdict

The market frames this as Amazon CodeWhisperer vs Grammarly, but the real comparison is workflow philosophy. Amazon CodeWhisperer gives you a Swiss Army knife for code with 15+ integrations. Grammarly does fewer things for writing but does them at 2x the quality. Pre-PMF, go Grammarly for speed. Post-PMF with a dedicated ops person, Amazon CodeWhisperer pays for itself in 3 months.
