Coeto Inc. (Headquarters: Tokyo, CEO: Kenji Minato), operator of the voice live streaming app 'Wacha', has launched 'Wai', a new feature where a 'Personal AI' trained on each streamer's voice, speaking style, and personality engages in 1-on-1 conversations with fans. By maintaining touchpoints between fans and streamers even when there is no live broadcast, it monetizes the 'blank space of disposable time' in the streaming industry and creates a new fan experience.
[Highlights of this release]
- 'Personal AI' trained on the streamer's own voice, speaking style, and personality chats 1-on-1 with fans 24/7.
- Maintains fan touchpoints even when not streaming. Can also be used as a traffic driver during live broadcasts.
- Zero additional operational burden for streamers; automatic learning and generation from past streaming data.
- Future plans include asynchronous monetization for streamers outside of live streaming hours via Wai.
Development Background: Live streaming enters an era of competing for 'quantity of touchpoints'
Fan needs have evolved from 'watching a few hours of streaming a day' to 'wanting to connect with their favorite streamer 24/7'. However, streamers have only one body and limited time, creating a structural gap where they cannot meet the fans' enthusiasm to 'talk more'.
Wacha has built a community where the distance between streamers and fans is close, centered on voice live streaming. 'Wai' is an initiative to extend this community value to 24 hours using generative AI, representing an industry-leading challenge that views the 'total amount of touchpoints' in the live streaming domain as a new axis of competition.
What is 'Wai'?
'Wai' is a new feature where an AI trained on the streamer's voice, speaking style, personality, catchphrases, worldview, and conversation logs chats 1-on-1 with fans 24/7. Fans can enjoy chatting with their 'favorite' Wai at any time from the chat screen within the app.
Conversations support both text and voice, providing an experience that is continuous with the streamer's activities, such as notifications for the start of a live stream and recalling episodes mentioned during streams.
Realizing an experience as if talking to the person themselves
Three features of the new 'Wai' function
✦ Feature 1: 1-on-1 conversation with the streamer's own voice and personality
The AI learns from past streaming data. It reproduces voice quality, catchphrases, and worldview, supporting both text and voice conversation formats. Fans can enjoy chatting at their preferred time—late at night, early morning, or during commutes—with the feeling of 'talking to the person themselves'.
It is possible to maintain touchpoints between fans and streamers even during times when there is no live streaming.
*Inappropriate remarks are automatically blocked by multi-layer filtering. It is clearly stated that it is an AI, designed not to damage the streamer's brand.
✦ Feature 2: 'Strongest traffic driver' to live streaming
When a streamer starts a live broadcast, a banner saying 'Currently LIVE / Watch Stream' is automatically displayed at the top of the Wai screen. Scheduled stream times are also announced in advance, completing the flow to viewing with the conversation with Wai as the entrance.
*Realizes a new fan acquisition flow where new visitors who are hesitant to join a live stream first experience the 'favorite' via Wai and then join the actual live stream.
✦ Feature 3: Zero additional operational burden for streamers
Collection of learning data, learning, public availability checks, and operational maintenance are all carried out by Wacha. Streamers can start using it just by replying 'OK to publish'. Both initial and monthly costs are free, and it can be stopped at any time.
*Learning data is strictly managed within Wacha and is not shared externally. Data deletion is also supported upon stopping.
Quality and Safety Initiatives
'Wai' adopts the following operational design to absolutely avoid damaging the streamer's brand:
- Automatic blocking of inappropriate remarks by multi-layer filtering
- Clearly stating that it is an AI within the conversation text
- Strict management of learning data without external sharing / Support for stopping use and data deletion at any time
- Established a system capable of responding to operational issues within 24 hours
Future Roadmap
Phase 1 (Initial release): Text chat, voice chat, automatic creation of Wai, live streaming notification linkage
Phase 2: Enhancement of emotional expression, improvement of response accuracy through real-time learning of past streams
Phase 3: Planned monetization outside of streaming hours and provision of fan-exclusive modes
About Wacha
'Wacha' is a voice live streaming app that emphasizes 'comfort' with a low barrier between streamers and listeners and a bidirectional nature. You can stream easily without showing your face, and up to 8 people can talk simultaneously with the hands-up function. Through the gifting function and a unique 'contribution reward' system (patent pending), it provides a mechanism to earn revenue just by participating in the stream.
