Worth knowing
Microsoft Copilot
- The free version is subject to available capacity and limits, and the pricing page does not give the numbers.
- Researcher and Analyst are not available on Microsoft 365 Personal or Family; they need Premium at $19.99 a month or Pro.
- On Microsoft 365 Family, AI features are available only to the subscription owner and cannot be shared with other members.
- According to Wikipedia, Microsoft said in August 2026 it would merge the consumer and Microsoft 365 Copilot apps and remove Mico, Deep Research and group chats.
Pi
- The app listings describe conversation only, with no mention of file analysis, image generation or coding tools.
- The App Store listing shows English as the app's only language.
- The App Store gives the app an 18+ age rating.
- The listings cover iPhone, iPad and Android; no desktop app is listed, so on a computer Pi is used in a browser.
