- -Now community-managed and described as in maintenance mode, with the original team's active work continuing under the renamed AG2 project
Pi
- +Free to use with no hard message cap, across web, mobile, and popular messaging apps
- +Designed around empathetic, emotionally intelligent conversation, with a natural real-time voice mode
- +Runs on Inflection's own proprietary models rather than third-party APIs
- -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
