About the author
Kenji tests the generative side of these apps: image output, voice calls, speech quality, response speed, and the controls that shape results. He looks for clean prompt handling, stable media generation, useful settings, and output that matches the character instead of drifting; he scores tools lower when voice sounds flat, media queues drag, or controls are too shallow to be reliable.
What I mark a tool down for
I mark a tool down when media features read like add-ons instead of working parts of the experience. If voice sounds stiff, images ignore prompts, video options are thin, or controls are too blunt, the score drops even when the chat is pass
How Kenji tests
How do you judge voice features?
I listen for pacing, clarity, interruption handling, and whether the voice matches the app's intended tone. A voice feature should feel usable for real conversation, not like a demo checkbox.
Can a strong image tool offset weaker chat?
Only up to a point. Good media features help, but this category still lives or dies on conversation quality and control. If the chat core is weak, media cannot carry the whole score.
What matters most in output control?
I want settings that do something predictable. If a tool offers style or generation controls, those options should change the result in a way you can actually feel and repeat.
