Kenning's take
What it does
Pi is a free chatbot from Inflection AI built for open-ended conversation rather than work tasks. People use it to talk through a problem, prepare for a hard conversation, learn about a topic or brainstorm, by typing or by talking in voice mode.
- text chat and live voice mode
- talking through decisions and hard conversations
- learning a topic or practising a language
- brainstorming and recommendations
Who it suits. Suits people who want a patient chatbot to talk things over with, not one for coding or heavy research.
