The core product showcased on the Hidoba Research website is the robot Captcha, alongside a new project called Callable. Captcha is a conversational AI robot that supports 10+ languages, customizable personalities and voices, natural speech flow, gaze and facial tracking, remote telepresence control, and a choice of standing or seated posture. Callable is positioned as a way to create an AI digital clone “with your knowledge” that “sounds like you.”
Based on the disclosed tech stack, Captcha’s LLM is custom and Mistral 7B-derived; its ASR is custom and Whisper-derived; its endpointing system is developed in-house and patent-pending; and its TTS is also custom. The hardware runs on Jetson Orin AGX, and the website emphasizes that everything is running locally. This is valuable for use cases that require low on-site latency, resilience under unstable network conditions, or edge deployment. Publicly listed use cases include educational speaking exams, debate moderation, AI education talks, trade show interactions, TV programs, and brand events.
The website does not provide specific pricing, free quotas, or trial information. It only mentions an Edge License, hourly API Calls, an Enterprise API subscription, and a voice API. There are clear signs of API and integration commercialization, but there is no documentation, SDK, rate-limit information, authentication method, or SLA details, making it difficult to assess the cost and effort of developer integration.
The main strength is its clearly differentiated product format: it is not just a web-based chatbot, but a combination of voice, visual expression, physical robotics, and remote telepresence. Local on-device operation may also deliver better response speed and on-site reliability. The downside is limited disclosure: Chinese language support is not specified, and while 10+ languages are claimed, the product appears to be mainly English-oriented. Details on privacy policy, data retention, enterprise compliance, and model performance metrics are also lacking. Claims such as “fastest conversational AI” and “natural speech flow” still need quantitative benchmarking to back them up.
It is better suited to enterprise customers in trade shows and events, educational institutions, brand marketing, robot demonstrations, remote telepresence, and scenarios requiring a voice API. Ordinary individual users who simply need a chatbot or digital human video tool may find the barrier to entry relatively high. The website does not state access conditions from China, so network connectivity and payment methods are unknown. For deployment in China, local alternatives such as iFlytek voice/virtual human solutions and Baidu AI Cloud XiLing may be worth comparing; international alternatives include ElevenLabs, D-ID, HeyGen, and OpenAI Realtime API.
