nidomi is a conversational AI Agent tool for website deployment, provided by Japan’s 株式会社ロケッタ/Rocketa, Inc. Its positioning is clear: helping website operators add an AI chatbot to their pages with a low barrier to entry. The official messaging emphasizes that it is “basically free.” After signing up, users can crawl their site content via a link, automatically create a trained AI Agent, and then deploy it by pasting the generated code into their website.
Based on the information on its pages, nidomi’s core value lies in automating the creation of a site assistant. After you enter a URL, the system crawls the website content and automatically generates a suitable prompt. It also supports registering knowledge sources, allowing the Agent to answer based on more accurate information. In addition, it offers web connectivity, enabling responses that use up-to-date information. On the model side, the free plan is marked as supporting OpenAI GPT-OSS. The upcoming Hobby plan will support GPT, Claude, and Gemini, but specific model versions, context length, call quotas, and rate limits have not been disclosed.
The clearest plan at present is the Free plan: ¥0/month, no time limit, no credit card required, including 1 AI Agent and use of OpenAI GPT-OSS. The Hobby plan is still listed as Coming, and is described as including all Free-plan features plus access to GPT/Claude/Gemini and the ability to hide the Powered by badge, but its price has not been announced. As a result, nidomi is well suited for free validation first, but less suitable for making a production procurement decision where cost, capacity, and SLA requirements are clearly defined.
Its main advantage is the very short onboarding path: sign up, automatically create an Agent, and paste the code—deployment can be completed in three steps. The free plan has no time limit and requires no credit card, making it friendly to personal webmasters and small to medium-sized websites. Knowledge sources and web connectivity can also improve practical usefulness. The main drawback is that the publicly available information is incomplete: key details such as message quotas, concurrency, data retention, privacy policy, admin permissions, conversation analytics, human handoff, and multilingual capabilities are not specified. Chinese-language support is also not clearly stated.
nidomi is suitable for Japanese or overseas website operators, personal projects, content sites, and corporate websites, for use cases such as FAQs, visitor inquiries, and Q&A over site content. Access conditions for users in China are unknown, and payment methods have not been disclosed. If used in mainland China, further testing is needed for network accessibility, embedded script loading speed, and the stability of the underlying model services. Comparable alternatives include Dify, Coze, Chatbase, Botpress, Tidio AI, and others.
