- +Designed around empathetic, emotionally intelligent conversation, with a natural real-time voice mode

- -Assistant-only: replies in chat and takes no actions, with no tools, automation, or autonomous browsing
- -Inflection's focus and most of its founding team shifted to Microsoft and an enterprise pivot in 2024, leaving the consumer product's long-term roadmap uncertain
