Provided by miibo, Inc., miibo is a no-code platform that lets you build conversational AI apps without programming knowledge. Released in April 2023 in Japan, it works by creating an “agent” in the admin console, registering the knowledge that its answers draw on, and choosing where to publish it — that is all it takes to launch a chatbot. The company claims implementation in as little as a day, and the platform integrates with existing databases and communication tools such as LINE and Slack. It is used for practical business tasks: automating inquiry handling, internal helpdesks, sales support, and report-grading assistance.
Key Features
- Create agents with no code: Enter an agent name, persona settings, and response policy in the admin console, and you have a conversational AI. There is essentially no point where you must write code, so non-engineers can own the whole operation
- A knowledge base so it answers with your own information: Register internal rules, product information, FAQs, and similar material as knowledge, and the agent answers on that basis. Integration with existing databases is supported as well, which suits cases where you need “your company’s answer” rather than a general-purpose chat
- Connectors let you choose where it runs: A single agent can be connected to a LINE official account, Slack, an embed on your own site, and other channels. Users can talk to it from the tools they already use
- Centralized management of multiple agents: Build separate agents by department or purpose and manage them together. This makes it easy to develop internal-facing and customer-facing agents in parallel
- External integration via API: An API is published for developers, so conversational features can be embedded into your own apps and workflows. You can start with no code and extend into code when the need arises
- Multiple language models and Thinking Mode: The platform adds support for new language models over time, so you can pick one to fit the use case. In March 2026, a “Thinking Mode” was added, in which the AI reasons through steps before composing its answer

The pricing structure was revised in September 2025, so figures and free-tier details in older articles may not match the current ones.
Pricing is as of August 2026. Amounts, including how tax is presented, may change, so please check the official pricing page for the latest information.
Pros & Cons
✅ Pros
- You can launch a conversational AI purely through the admin console, so organizations without development resources can get started
- Developed and operated by a Japanese company, with documentation and support material available in Japanese
- Connects directly to channels already in use inside and outside the company, such as LINE and Slack
- You can test on the free Trial plan before moving to a paid one
- Supports a staged approach: start with no code, extend with the API
⚠️ Cons
- The conversation-credit model means plans need revisiting as usage grows, and costs can be hard to predict
- Credit consumption changes with the language model you choose, so model selection and cost must be considered together
- Getting the answers you want takes effort in curating knowledge and tuning settings — even with no code, building it is not the end of the job
- Once you go further into embedding advanced business workflows or a custom UI, you do end up needing API and development knowledge

Who Is It For
- Small and mid-sized businesses and sole proprietors that want AI to handle inquiries or an internal helpdesk but cannot spare development resources
- Staff already running a LINE official account or Slack who want to add AI responses there
- IT and communications staff who need a chatbot that answers based on their own rules and product information
- Organizations that value Japanese-language documentation and support and prefer a domestic service
- Development teams that want to validate with no code first, then embed it into their own systems via the API
Summary
miibo is a Japanese no-code platform that shifts building conversational AI from “an engineer’s job” toward “the responsible staff member’s job.” Its practical strength is the combination of a knowledge base and connectors, which delivers answers grounded in your own information through LINE or Slack. On the other hand, managing costs under the conversation-credit model and curating knowledge to raise answer quality remain work for the operating side. A reasonable approach is to start on the free Trial plan, check how far it can answer the inquiries you have in mind, and then pick a plan.
