Sesame launches its voice-companion iOS app (Maya, Miles, Simone, Charlie) in public preview
Sesame, the Oculus co-founders' conversational-voice startup behind the viral Maya/Miles demo and the open CSM-1B model, released a free public-preview iOS app on 2026-05-28 in 39 countries. It has four voice agents (Maya, Miles, Simone, Charlie), each with its own personality and memory. An Android preview is planned and smart glasses are targeted for 2027.
Key facts
- Four agents: Maya, Miles, Simone, Charlie; 39 countries; free at launch; possible waitlist
- Company raised a $250M Series B (Oct 2025, Sequoia and Spark)
- Open model: sesame/csm-1b (Apache-2.0, March 2025)
What happened
After a year of web demos and a closed beta, Sesame shipped its natural-sounding voice companions as a consumer iPhone app.
Why it matters
Sesame's early-2025 demo reset expectations for conversational voice realism. The app tests whether voice-first companions become a daily habit before Sesame's planned glasses hardware.
