> Emotionally intelligent personal AI for talking things through

## Key features

- **Voice mode:** Talk with Pi live by voice instead of typing your side of the conversation.
- **Learning and language practice:** Explains a new topic in conversation and can act as a partner for practicing a language.
- **Planning and brainstorming:** Helps turn something new into an action plan, generates ideas and suggests things such as what to watch next.
- **Adapts over time:** Inflection says Pi evolves and understands you better the more you talk with it.

## Good for

- Talking through decisions, worries or difficult conversations
- People who would rather speak with an assistant than type
- Casual learning and language practice at no cost

## Worth knowing

- 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.
