I tried Cursor and Grammarly for a week. One of them is going in the trash.

I want the one that disappears into a workflow instead of becoming a project. My call: reach for Cursor when edits your real codebase, and Grammarly when catches grammar and tone in real time everywhere. They cover different days, and pretending otherwise is how people end up paying for both and using neither.

What Cursor does best: edits your real codebase, not just snippets

What Grammarly does best: catches grammar and tone in real time everywhere its rephrase suggestions are genuinely useful

The catch on Cursor: indexing a big repo is heavy and slow And Grammarly? the useful features sit behind the paywall

One honest note: the integration that paid for itself is where Cursor and Grammarly both still need a human in the loop. I stopped expecting either to be fire-and-forget.
