Is there a Microsoft Copilot alternative that works in every app?
The short version: Opsis writes your next line wherever you type: Slack, Gmail, Outlook, Teams, Notion, Google Docs and AI chats like Claude and ChatGPT. Press Tab to keep it. It can also draft a whole reply from a few notes, using facts from your own work: what's on your screen, the apps you connect (Gmail, Calendar, Drive, Slack, Notion, GitHub, Linear, Outlook) and your history. It isn't tied to one vendor's apps, so the same Tab-to-keep flow works in Slack and Gmail as in Outlook and Teams.
Microsoft's Copilot features are built into Microsoft 365 apps and Windows, and what you get depends on your licence. That is useful if your whole day is in Word and Outlook. It is less useful if you answer clients in Slack and email in Gmail.
