Overview

End-to-end AI agent that ingests information, routes queries, and responds in multilingual Telegram chats.

The AI Agent ingests data from websites and Google Drive, creates embeddings, and stores them in a vector store for fast retrieval. A Supervisor AI routes user queries to domain-specific agents (News, Product, Academy) based on intent. It answers in the user's language via Telegram, translating as needed and updating knowledge as data changes.

Why you should use Multi-language Telegram RAG Chatbot

Automates multilingual customer interactions and centralizes knowledge via a Supervisor AI. Reduces manual data handling by consolidating ingestion, routing, and translation into a single AI agent.

Before
Data sits in multiple places (Drive, websites, documents) and isn’t easy to search.
Non-English queries require manual translation and slow responses.
Agents must be triaged and handed off to domain experts, causing delays.
Knowledge data becomes stale as documents are updated without automation.
Keeping data synchronized across systems is error-prone and repetitive.
After
A centralized, multilingual knowledge base that updates automatically.
Faster, accurate responses in the user’s language with domain-aware routing.
Automatic routing to News, Product, and Academy agents as needed.
Live data retrieved from the vector store and Postgres without manual pulls.
Consistent translations and tone across all languages and content.
Process

How it works

A simple three-step process from ingestion to chat.

Step 01

Data Ingestion & Processing

Ingests content from Google Drive and websites, cleans it with AI, and creates vector embeddings stored in a vector database.

Step 02

Data Deletion

Periodically checks a Google Sheet for records marked as deleted and removes the corresponding data from the vector store and Google Drive.

Step 03

Chat Interface & Logic

Receives Telegram messages, detects language, uses a Supervisor AI to route to News, Product, or Academy agents, retrieves data with RAG, and returns translated responses.


Example

Example workflow

A realistic scenario showing task, time, and outcome.

Scenario: A French-speaking user asks for the latest features of Product X in the Sales channel. Within 2 seconds, the bot translates the query to English, delegates to the Product AI Agent via the Supervisor, retrieves current product details from Postgres, and replies in French with a concise summary and relevant links.

FAQ

FAQ

Common questions and practical answers.

The Telegram interface supports multiple languages through built-in translation. The system detects the user’s language, translates to English for processing, routes to the appropriate domain agent, then translates the response back to the original language. You can customize language pairs per agent and prompts to maintain tone. Translation quality depends on the prompt and model choice, but the workflow ensures consistent language handling across agents.

Data ingested includes websites via web scraping, Google Drive documents, and Google Docs, PDFs, and Word files. The ingestion layer converts content into chunks, creates vector embeddings, and stores them in a vector database for fast retrieval. The system also monitors for updates and deletions to keep the knowledge base current.

The Supervisor AI analyzes the user query context and domain cues, then selects the most relevant domain agent (News, Product, Academy). It uses prompts that describe each agent’s responsibilities and access to data, ensuring routing aligns with user intent. If data is missing, it can proceed with partial retrieval and fallback responses.

Data privacy is handled through access controls, credentials management, and secure data storage. The vector store and databases can be hosted on your infrastructure with strict role-based access. All data transfers use encrypted channels, and you can audit who accessed what data and when.

Yes. You can create additional sub-agents and data sources by adding new workflow tools and prompts for the Supervisor. You will update prompts to include new capabilities, and wire new sub-workflows to handle them. This keeps the system extensible while preserving routing accuracy.

Set up test queries in multiple languages and domains to verify routing, retrieval quality, and translation. Validate results against a known data source and measure latency. Use versioned prompts and monitor data freshness to ensure ongoing accuracy.

You’ll need credentials for services such as OpenAI, Supabase, Google Drive/Sheets/Docs, a Telegram Bot, and a Postgres database. Configure these in your workflow credentials, and ensure permissions are scoped to the necessary data. Rotate credentials regularly and monitor access logs for unusual activity.
