How to choose between them
The trade-offs that follow from the figures above, rather than a single winner.
- Claude starts cheaper — $20 a month against $30 for Grammarly.
- At ten people the gap is $100 a month, in Claude's favour — the pricing models diverge as the team grows.
- They charge differently: Grammarly is seat based and Claude is flat rate. That, not the headline price, decides which is cheaper at your size.
- Their scores are within half a point of each other, so neither is the obvious choice on our scoring alone.
