Perplexity rolled Personal Computer out to every Mac user this week, and I keep snagging on the name. The thing is a Linux VM running in Perplexity’s datacenter, streamed to a window on your laptop, and they decided that’s “personal.” Personal the way a hotel room is personal. Someone else owns the building, you brought a toothbrush, tomorrow it belongs to a different guest who probably watches different shows.

So I tried it. Boot it up, a desktop materialises, you ask it to book a flight or dig through an inbox, and the demo bits work fine. But it isn’t yours. No logins. No cookies. No extensions. No memory of the last seven years you’ve spent quietly turning the open web into a place where you, specifically, are signed in.

What you’re actually renting

The agent opens a fresh Chromium and walks face-first into the same wall every cloud browser hits. Google asks for a password. Notion asks too. Your bank wants 2FA on a device it has never seen before, sitting on an IP in Oregon while you live in Toronto, and now there’s a suspicious-activity email pinging your phone while the agent waits patiently in the cloud for you to finish proving you exist. The “personal” experience reduces, then, to whichever credentials you’re willing to type into a streamed session piped through somebody else’s hardware, and that whole session evaporates the second the task ends, so the dance starts over the next time you ask for anything.

This is not a bug they’ll patch. A datacenter VM cannot see your local Chrome profile any more than my laptop can see yours. There’s no shared state. There is no shared anything.

Hotel room

Strip out the part where your files sit on the drive in front of you and what’s left is a thin client with a marketing budget.

The gap a real browser agent doesn’t have

A browser agent that runs inside your actual tab is operating inside the session you spent months building up by being a person on the internet, the one where you opened Gmail this morning and stayed signed in, where you’re already in Notion and Linear and your CRM and your bank and the staging environment for whatever weird internal tool your company shipped in 2019 that nobody fully documented because the engineer who wrote it left in 2021. All that authenticated state lives in your local Chrome, scoped to your machine. So an extension agent reading the side panel acts on the page in front of it with the permissions you already granted yourself by being logged in. No OAuth scope screen. No retyping creds into a streamed VM. No “please sign in to continue” loop forty seconds into a workflow you wanted finished half an hour ago.

That’s the gap cloud browser agents can’t close, and the Perplexity Mac rollout is the loudest demonstration of it I’ve seen all year.

dassi runs as a Chrome side panel instead. Your tabs are the context. Boring sentence, true sentence.

The fresh-VM tax

Every cloud agent does the same opening number before getting to any actual work:

  • Sign in to Google
  • Sign in to whichever SaaS thing
  • Wait for the captcha
  • Approve the new-device email Google fired off because the IP looks suspicious
  • Solve a bot challenge clearly designed to stop bots
  • Watch the whole session vanish when the run ends

By the time the agent’s warm, you could’ve done the damn task yourself with two tabs and half a coffee.

So why ship this

Because cloud VMs ship faster than browser extensions. No Chrome Web Store review. No profile-sharing edge cases. No permissions UX to argue about with users who already aren’t sure they trust you. And what falls out the other end is a slick Twitter demo and an agent that doesn’t know your boss’s email address. There’s more on this in the post on why your AI agent can’t see that you’re logged in.

Faster shipping, fewer reviewers, worse product. Pick two.

What personal should probably mean

A personal computer isn’t one sitting in a building two states over with your name on a sticky note taped to the rack. It’s the one with your tabs open right now. Anyone shipping browser automation that ignores that is solving a different problem and pricing it like they solved yours.

If you want an agent that actually sees your logged-in tabs, dassi is a Chrome extension running in your real browser, using your real session. Same models. Same prompts. Different plumbing. Plumbing turns out to be the whole game.
