Value proposition

Wisora enables companies to easily create and operate AI bots that respond immediately to inquiries by ingesting web pages, PDFs, manuals, and Office documents — no coding or AI expertise required. It uses RAG (Retrieval-Augmented Generation) for accurate, context-aware responses and integrates with LINE (via L-Step), Slack, Microsoft Teams, and web widgets.

Wisora Starter (¥40,975/month, 1,000 requests/month, web/Slack), Wisora Pro (¥134,750/month, 5,000 requests/month, adds Teams/LINE/SSO), Wisora Enterprise (custom pricing, API integrations, advanced accuracy engine)

Unique value

Enterprise-grade AI chatbot service that can be set up in hours with zero coding, trained on company-specific documents, and deployed on Japan's dominant messaging platform LINE — all from a company (SORACOM) with deep IoT/enterprise credibility and KDDI backing.

Target customer

Japanese enterprises and SMBs needing AI-powered customer support automation, internal help desks, and marketing website Q&A — particularly those using LINE official accounts for customer communication

Industries served

Customer Support, Internal Help Desk, Marketing & Sales, E-commerce

Technology advantage

RAG-based architecture automatically builds search-augmented generation from uploaded documents; supports multi-language (Japanese docs auto-answer in English); LINE integration via L-Step; Google Drive folder ingestion; conversation log analysis for continuous improvement; built on SORACOM's enterprise IoT platform infrastructure with KDDI group backing

How they differentiate

Unlike generic AI chatbot platforms, Wisora is purpose-built for the Japanese market with native LINE integration (via L-Step), strong enterprise security (SSO, Box integration), and is backed by SORACOM/KDDI's existing enterprise relationships. The zero-code setup and 14-day free trial lower adoption barriers for Japanese SMBs.
