AI Agents
Japanese AI agent platforms use large language models to understand natural language and carry out work on a user’s behalf. They take many shapes: secure chat assistants, API inference infrastructure, no-code app builders, and agents that handle inbound phone calls.
What ties them together is the shift from answering questions to doing the task: drafting documents, researching topics, transcribing audio, and running multi-step workflows that staff would otherwise do by hand.
Free Tier
A free usage tier lets you run small workloads at no cost, so a team can test the service and handle light real-world use before committing to a paid plan.
