The upsell you did not ask for
The easiest way to get bundled AI at work is to pay for the office suite that carries it. Microsoft 365 Copilot and the Gemini features in Google Workspace both sit behind a paid seat, added to every account you run. If your team lives in Word, Excel, and Outlook all day, that can make sense.
Plenty of small businesses do not. They run a lean stack: Zoho-tier mail, a spreadsheet here, a few browser tabs there. Upgrading every seat of a full office suite just to unlock an AI assistant is a big bill for a feature you could get on its own.
Copilot is $28 per person each month, and that sits on top of the suite seat you are already paying for. Across twenty people, a year of it looks like this next to the same team on credits.

You do not have to upgrade the whole suite
AI does not have to be a rider on a productivity subscription. Drephos is a standalone workspace for the models themselves: Claude, GPT, Gemini, and others in one place, reached through the browser, no suite migration required.
You keep the mail and tools you already have. You just add the AI, and only the AI.
One wallet, every model, caps you control
Drephos is one prepaid wallet the whole team shares. You top up in USD packs, add people with a single join link that you can lock to your company email domain, and set a monthly cap per member so nobody runs away with the balance. A per-member usage view shows who spent what. Credits are valid a full year, refreshed on every top-up, and free models work with a zero balance, so you can try it before you pay.
No per-seat suite upgrade, no new email platform, no lock-in.
When the bundled AI is worth it
To be fair: if your team is already all-in on Microsoft 365 or Google Workspace and works inside those apps constantly, the built-in assistant is right there in the document you are editing, and that tight integration is worth something. Drephos is the better fit when you are on a leaner stack, when you do not want to upgrade every seat of a suite, or when you would rather pay for AI usage than a standing per-person fee.
