The honest starting point: Copilot doesn't do Slack
Copilot's home is Teams, Outlook, and Office files. There's no Slack-native Copilot — at best you'd bridge summaries across, which defeats the point of an assistant that's supposed to remove steps. If Slack is where decisions happen, your AI needs to read the thread, not a forwarded copy of it.
Side by side for a Slack-first company
| Microsoft 365 Copilot | Yasmine | |
|---|---|---|
| Native home | Teams + Office apps | Slack |
| Sees your team's context | Microsoft Graph (Outlook, OneDrive…) | The channel itself + 1,200+ tools |
| Output | Drafts inside Office apps | Finished tasks in the channel — drafts, reports, PRs |
| Memory | Session-based | Per channel, persistent |
| Model | OpenAI via Microsoft | Your keys: OpenAI, Gemini, or Claude — or your Claude account |
| Isolation | Shared cloud tenant model | Dedicated microVM per workspace |
| Pricing | Per seat, annual commitment | Per workspace plan, 7-day free trial, cancel anytime |
What 'works where you do' means in practice
Ask in #finance: "build the monthly expense summary" — Yasmine pulls from your connected tools and posts it in the thread.
Ask in #eng: "fix the broken link on the pricing page" — she opens the PR and waits for approval.
Ask in #marketing: "turn this thread into a launch brief" — the brief lands in the channel, not in a file you have to go find.
When Copilot is still the right pick
If your company genuinely lives in Teams and Office — Outlook mail, OneDrive files, Excel everywhere — Copilot's deep Office integration is hard to beat and you should use it. This isn't a knock: it's about where your work actually happens. Slack company? Get an AI that's native there. (Comparing more options? See Viktor vs Yasmine vs Claude Tag.)
