The Challenge
Getting real conversation practice with a human tutor meant waiting hours or days for a slot, then paying $50 to $100 an hour once you got one. Most learners never moved past reading and vocabulary drills, because live practice was expensive, hard to schedule, and intimidating. One wrong word in front of a real person was enough to make someone stop practicing altogether.
Existing apps made it worse: scripted dialogue, one-size-fits-all lessons, and no adaptation to how fast a learner actually needed to go.
The Solution
New York App Devs built Senthora AI as a mobile app where a real-time voice AI tutor stands in for a scheduled human one, available any time a learner wants to practice.
The voice pipeline runs on LiveKit, real-time audio infrastructure that keeps the AI's voice level steady and stops the AI and learner from talking over each other. A subscription unlocks unlimited practice after a 7-day trial.
