Reviewer scorecard
“The Workflows feature is interesting but for developers, a simple API call to Claude or GPT-4 is more flexible.”
“For developers, the code comment corrections are annoying and the VS Code extension adds latency. I disabled it for coding but keep it for emails and docs.”
“Generic AI output that needs heavy editing. Claude or ChatGPT with a good prompt produces better results.”
“Grammarly lives in my browser and catches mistakes before anyone else sees them. The tone detection feature has saved me from sending passive-aggressive emails more times than I'd like to admit.”
“Another AI wrapper struggling to differentiate as base models get better. The moat is evaporating.”
“In the age of ChatGPT, Grammarly's value is in-context editing, not generation. It fixes your writing in place — emails, docs, code comments. Different tool, different job.”
