An honest comparison
Zonlo vs Speak
Both apps care about actually speaking, which already puts them in rare company. They just start from opposite ends: Speak maximizes minutes spent talking with an AI partner; Zonlo prepares you for one specific real conversation.
What Speak is genuinely great at
Speak is one of the strongest speaking-focused apps around. It gives you high-volume conversation practice with an AI partner, its speech recognition is widely praised, and it gets you talking from the first minute instead of tapping through flashcards. If your goal is raw volume of speaking time with instant responses, Speak has earned its reputation.
Where Zonlo is different
Speak is built around an AI conversation partner: an always-available chatbot to talk with. That is powerful for volume, but it is still a performance in front of something that responds, and for people who freeze when speaking, that can feel like the very situation they are avoiding.
Zonlo has no chatbot and no persona. It is a private rehearsal space: you pick a real moment (ordering coffee, checking into a hotel), say your reply out loud, and get wins-first feedback: what worked, then one small tweak. The conversation continues through authored exchanges, so difficulty never drifts and nothing improvises at you. For Japanese, a morphological analyzer checks your politeness level alongside the grader. No streaks, never a red mark, and your audio never leaves your phone.
If you want both volume and calm, they can stack: Speak for open-ended talking time, Zonlo to rehearse the exact conversation you are nervous about.

Common questions
How is Zonlo different from Speak?
Speak is built around open-ended conversation with an AI partner and optimizes for volume of talking. Zonlo is a rehearsal space: you take part in short, authored conversations one reply at a time, with wins-first feedback and no chatbot persona, and optimizes for walking into a real conversation calm.
Is there a Speak alternative without an AI chatbot?
Zonlo is one. There is no AI persona to perform for: you rehearse your side of realistic scenarios out loud and get structured feedback on what you said, including how polite you sounded.
Does Zonlo handle Japanese politeness levels?
Yes. Japanese replies are checked for register (casual versus polite forms) with a morphological analyzer working alongside the grader, and the feedback tells you when your politeness level fits the scene.
Which app is better if speaking makes me anxious?
Zonlo was built for exactly that person. There is no AI partner watching you perform, no streaks, and never a red error mark; feedback opens with what you got right, and your audio never leaves your phone. Speak is excellent if what you want is maximum talking volume with instant AI responses.
