Why You're About to Pay for the Wrong AI Agent

Three different AI agents will now run your busywork while you do something else — answer email, book a reservation, fill a grocery cart, draft the report. One of them costs $100 a month. The other two cost $20. And the $100 one is the version most people are about to sign up for. That's usually the wrong move — not because it's bad, but because the right agent has almost nothing to do with the logo on it and everything to do with where your work actually happens.

TLDR: Google just put its 24/7 agent, Spark, behind a $100 plan, while ChatGPT and Claude hand you a comparable agent for $20. Here's what that extra $80 really buys, where each agent actually lives, and a 30-second way to tell which one fits you.

Here's the part nobody says out loud: all three companies have a $20 plan. ChatGPT includes its agent at $20. Claude includes Cowork at $20. Google's $20 tier doesn't include Spark at all — to get it, you jump to the $100 plan.

So what's the extra $80 for? Four things: Spark itself, 5x higher Gemini limits, 20 TB of storage, and YouTube Premium. Look again — half that list, the storage and an ad-free YouTube subscription, has nothing to do with AI. Unless you genuinely want those, you're paying about $80 a month to unlock one feature the others give you for $20.

The price gap doesn't buy a smarter agent. It buys where the thing runs — and that's the whole decision.

Two of the three run in the cloud, so your laptop can be shut. Only Spark is truly hands-off 24/7 — it watches your inbox and runs on a schedule with no prompt. Cowork is the one that needs your machine awake, because it works the apps on your actual desktop.

Could you build your own always-on agent? Sort of — you can rent a cloud computer and wire one up, but that's a technical project most people will never touch. What Google did with Spark is do all of that for you, already inside the Gmail and Docs you open every day. That convenience — not a magic power — is the $100. And Google isn't alone: Perplexity and Grok are circling the same space fast.

Before you upgrade, ask the cheaper question: not which agent is best — which one already lives where you work.
