Voice AI lab Sesame opened the iOS preview of its mobile app on May 27, 2026, shipping with four named voice agents and an incognito mode for ephemeral conversations. The app moves Sesame's Maya and Miles demos out of the browser research preview and into a phone-resident assistant with real-time search, image cards, and contact-aware memory.
Try it: Four agents, one phone, in 10 minutes
Request access at sesame.com/mobile-preview and install the preview build through TestFlight when the invite arrives. Open the app, pick one of the four agents (Maya is the most expressive, Miles is the lighter-weight alternative), and start a session. Try a multi-turn conversation with a search query embedded ("find me three sushi places nearby and pull up their menus"). The agent returns voice plus real-time search cards with images inline. To run a session without history, flip on incognito mode in settings; the conversation evaporates when you close it.
Why it matters
Sesame's web demo of Maya and Miles went viral earlier in the year for sounding less like a synthesized voice and more like a person. The iOS app is the first time that voice quality lands in a daily-use form factor with multimodal output (search cards, images) bolted on. It positions Sesame as the closest realistic challenger to ChatGPT's Advanced Voice Mode and Anthropic's recently expanded Claude Voice Mode, both of which are voice-first but text-heavy in their visual surface. Sesame is building toward intelligent eyewear in 2027, and the phone app is the bridge product that proves the voice agent layer works in everyday contexts.
Key details
The preview ships with four personal voice agents. The two flagship voices are Maya, Sesame's most advanced speech model, and Miles, a less-trained alternative for users who want a different tone. The other two agents are unnamed in the leak but referenced in the build. Search cards render inside the conversation surface with images, so an agent answering "what's playing nearby" can return real-time results with poster art rather than reading URLs out loud. Incognito mode discards the session after close. Sesame describes the company mission as "personal agents for curious people" and frames the iOS preview as a stepping stone toward ambient intelligence delivered through smart eyewear in 2027.
What to do next
If you work in voice UX, audio production, or conversational design, request the iOS preview now; the build will surface design choices the public Maya web demo did not. For creators who already use ChatGPT Advanced Voice or Claude Voice Mode for ideation, test Sesame on the same workflow and compare on naturalness, interruption handling, and how cleanly the agent integrates inline search.
