Resume keeps one session alive. Grov gives you knowledge from all past sessions (yours + your team's), filtered to what's relevant right now. It's really built for teams using coding agents to build software together.

Example: My cofounder debugged the payment flow last week. When I touch payment code today, his reasoning is automatically injected into my session.

Alright sounds nice - I guess for teams it makes sense then but as a soll developer, claude resume currently works well:)
