Key takeaways for Teti: Private AI Assistant

Where is it heading?

The AI assistant market is consolidating around high-utility, low-friction tools, and Teti's growth depends on proving that privacy does not require sacrificing performance.

  • High trust in the privacy-first architecture drives strong sentiment, which creates a loyal base that is less sensitive to feature-parity gaps.
  • Technical instability in interactive features (voice, screen sharing) creates a friction point that prevents Teti from becoming a daily-use habit for power users.
