Copilot Pro vs AIWITH.CHAT: $20 for Office Integration or $9.9 for Five Models?
Microsoft Copilot Pro built its pitch around the apps most people already have open all day: Word, Excel, PowerPoint, Outlook. AIWITH.CHAT starts from a different question — not which office suite it plugs into, but which model actually gets a given task right. They overlap enough on price and audience that anyone deciding between "AI subscription" options should compare them directly.

Copilot Pro: the AI that lives inside your documents
If your work already happens in Word and Excel, Copilot Pro's advantage is real: draft a doc, get suggestions inline, ask it to summarize a spreadsheet without ever leaving the app. That convenience is the whole product — pay $20/month and it's an assistant with editing access to what you're already writing, not a separate tool to switch into. What you don't get is a choice of model: it's OpenAI's models, full stop, whether or not that's the best model for the task in front of you.
AIWITH.CHAT: pick the model, not the app
AIWITH.CHAT doesn't touch your Office files — it's a chat window, not a plugin. What it trades that integration for is model choice at less than half the price: $9.9/month for GPT-5.6, Claude Fable 5, Gemini 3.1 Pro, DeepSeek V4 and Kimi K3, all in the same conversation. Ask GPT for a first draft, switch to Claude to tighten the reasoning, pull in Gemini for a document too long for the others to hold in context — no extra subscription, no re-pasting the conversation into a new tab.
Which one actually fits
- You live in Word/Excel/Outlook and want AI assistance baked into those apps → Copilot Pro is built for exactly that; AIWITH.CHAT won't touch your files.
- You want a chat interface where you're not locked into one vendor's model, and you're not trying to save $20/month on an Office subscription you already have → AIWITH.CHAT gets you five models for less than half of Copilot Pro's price.
The two aren't really substitutes for the same job — one is an in-app assistant, the other is a model-agnostic chat subscription. But they're both a recurring AI line item on the same budget, so it's worth being clear about which one you're actually paying for: the integration, or the choice of model.
