Genspark makes a fair point about AI browsers. Its download page promises "On-Device Free AI" that runs models locally. That is the right direction. But the same page says the on-device AI "is available exclusively in the Genspark browser". To get it, you move your browsing to Genspark.
Off Grid AI Desktop (OGAD) brings the local model to you instead. It works in the Chrome you already use, through an extension, with a model running on your own computer. And it does far more than browse: it remembers your work, takes your meeting notes, and runs on your phone.

Checked 30 October 2026 against Genspark's browser download page. We could not load a current Genspark price, so this article does not compare cost. Off Grid AI Pro is $79.99 once, a limited-time lifetime price down from $119.
Local, and in the browser you already use
Switching browsers has a real cost. Your logins, saved sessions, extensions and habits live in Chrome. OGAD leaves them there. The extension pairs with the desktop app, and the model runs in OGAD.
- Install the Off Grid AI extension in Chrome and keep OGAD running.
- In the extension, open Settings > Desktop and choose Pair with desktop. Check that the six words match, then approve in OGAD.
- Ask about the page you have open. Plain chat gets read-only tools, so it reads and answers.
- Turn on Agent for a task that needs clicks across pages. It uses the sessions you already have.
- When the task wants to send, create or delete something, OGAD shows the action. You approve it or reject it.
You also choose the model. OGAD shows which models fit your computer, and it can use compatible GGUF files you already have. See how to summarise web pages with local AI in your browser.
The browser is one part of Pro
Genspark is a browser. Off Grid AI Pro is your whole working day, on your own hardware:
- Memory. Your screens, meetings, mail and documents become one local memory you can search and ask.
- Meetings without a bot. Calls are recorded, transcribed and summarised on your computer.
- Actions you approve. It drafts replies and issues through Gmail, Linear, Jira and Notion. Nothing goes out without your yes.
- God, your chief of staff. A morning brief, meeting prep with notes from last time, and the to-dos people owe you.
- Reflect, Vault, Clipboard and Sync. Where your day went, passwords encrypted on your disk, every copy searchable, and your phone and computer in sync, device to device.
All of it is in the same $79.99, on up to 5 devices. Browser chat stays free.
When Genspark is the better pick
Genspark ships a whole browser with an ad blocker, a large MCP Store and a shopping helper that compares deals and reviews. If you want a new browser and free on-device chat out of the box, it is a reasonable pick. It also runs on Intel Macs. OGAD's Mac app needs Apple silicon.
Check one thing first. Genspark's page does not say whether Super Agent and Autopilot run on your device too. If your pages hold client, legal or deal details, ask before you hand them to an agent. With OGAD, you pick a local model and the whole task stays on your machine. Its extension is on Chrome today; Edge, Brave, Arc and Firefox have a waitlist.
Switch in ten minutes
- Download OGAD for Mac, Windows or Linux.
- In Models, download a text model that can use tools. The app shows which fit your computer.
- Add the Off Grid AI extension to Chrome and pair it with the desktop.
- Ask a question about the page you have open.
- Get Pro when you want browser tasks, memory, meetings and the Vault.
