Pros & Cons from Real Users Pros As someone who already lives inside Google Workspace every day, Gemini Spark feels like the missing piece Google has been building toward. The integration with Gmail, Docs, Slides, and Calendar is incredibly smooth, and it actually feels useful instead of gimmicky. I love that Spark works in the background even after I close my laptop, which makes it feel more like a real digital assistant than a chatbot. Cons Since Spark is still rolling out, there are moments where it feels early-stage. I still review important drafts and automations before relying on them completely. For more sensitive tasks, I appreciate that it asks for approval first, but it also means some workflows are not fully hands-off yet.	Pros & Cons from Real Users Pros Hark is much closer to a real assistant than a normal chatbot. I can give it something that actually needs to get done, and it can use websites and apps on my behalf instead of just explaining the steps. The memory is a big part of why it feels useful. Hark can keep track of context across work and personal tasks, so things like scheduling, travel, reservations, shopping, and project follow-ups do not have to start from zero every time. Cons The main downside is trust. Hark can act on your behalf and securely manage logins to a lot of services, so I would still keep a close eye on anything involving money, sensitive accounts, or important external actions.
