AI spatial-audio companion that helps blind and low-vision users explore indoor spaces
Directional sound cues are positioned around the listener so the location of nearby objects and obstacles is conveyed through hearing rather than sight.
Ask spoken questions about your surroundings and receive AI-generated descriptions, such as what items are placed on a table or counter.
Depth sensing plus AI helps identify and locate objects and explore paths around indoor obstacles, with the caveat that this remains an experimental capability.
Control the app and ask questions hands-free by speaking to Siri, so the phone does not need to be handled during use.
An AI speaking coach that turns daily voice practice into measurable progress
Practice interviews, salary talks, and other high-stakes conversations with an AI character that responds, pushes back, and scores how you handled the exchange.
Tongue twisters and articulation drills scored instantly for speed and clarity, with leaderboards that turn routine practice into something you return to.
Match pitch curves in real time to develop melody and presence, because intonation is a big part of sounding confident.
Guided breathing patterns help you settle nerves before a meeting, a stage appearance, or a call, rated helpful by the large majority of users.
