Automated AI Response Bot with RAG System

Your organization's knowledge — manuals, contracts, product specs, internal wikis — made instantly searchable through a conversational AI. Instead of keyword search, your team asks questions in plain language and gets accurate, cited answers in seconds.

Built on a retrieval-augmented generation (RAG) pipeline: documents are chunked, embedded, and indexed. At query time, semantically relevant passages are retrieved and passed to the LLM, which synthesizes a grounded response with source references.

Multi-format ingestion PDF, Word, Excel, PowerPoint, HTML, plain text — all processed and indexed
Hybrid search Dense vector search + BM25 keyword matching + re-ranking for accuracy
Source citations Every answer links back to the exact document and section it came from
Bilingual support Japanese and English documents, queries, and responses — mixed-language friendly
Flexible interfaces Web chat UI, Slack bot, LINE bot, or embedded widget — your choice
Access control Role-based document visibility — staff see only what they're allowed to
10K+ Documents per deployment
< 3s Avg. response time
85% Query accuracy

Quick Wins

Smaller, focused engagements — typically 2–6 weeks to production. These map closely to common pain points in Japanese organizations.

01

LINE Bot + RAG

Connect a RAG knowledge base to LINE — Japan's dominant messaging platform. Employees or customers ask questions; the bot answers from your documents. No new app to install.

02

Meeting Minutes AI

Record a meeting → get structured minutes in minutes. Transcription, speaker separation, action-item extraction, and formatted output to Notion, Google Docs, or email. Japanese and English supported.

WhisperLLMNotion API
03

Excel Report Automation

Replace the monthly copy-paste ritual. An LLM agent reads source data, fills in templates, generates commentary, and emails the report. Works with existing Excel formats — no workflow changes needed.

Email Auto-Draft

Incoming emails are classified, summarized, and routed. For routine requests, a draft reply is generated and queued for one-click approval. Reduce response time from hours to minutes.

Document Q&A for Manuals

Upload product manuals, safety guides, or compliance documents. Staff ask questions in natural language instead of searching 200-page PDFs. Answers include page references. Ideal for manufacturing and operations teams.

06

Multilingual Customer FAQ Bot

A lightweight chatbot trained on your FAQ / support docs, deployed on your website or Slack. Handles JP/EN mixed queries. Routes unresolved cases to a human agent. Fast to set up, measurable deflection rate.

How We Work

01

Discovery

A 30–60 min call to understand your data sources, team workflows, and the specific problem you want to solve. No sales pitch — just diagnosis.

02

Prototype

A working proof of concept — usually in 1–2 weeks — so you can see the system with your actual documents before any large commitment.

03

Build & Deploy

Production-grade implementation with monitoring, access control, and documentation. Handed off to your team with full source code.

04

Iterate

Ongoing support and refinement based on real usage data. Retainer or per-project — structured around what works for you.

Have a problem in mind?

Even a rough idea is enough to start. Describe what's slow, manual, or broken — and we'll figure out together whether AI can help.
