Chat with your email history using Telegram, Mistral and Pgvector for RAG

Retrieval-Augmented Generation combines AI language models with database search to provide accurate answers from your email history. The system first searches your emails using vector similarity (Pgvector), then uses Mistral AI to generate natural language responses based on the found content.

This two-step process ensures answers are both relevant and coherent. Unlike traditional keyword search, RAG understands the meaning behind your questions and can synthesize information from multiple emails into a single response.

• Understands conceptual relationships between emails
• Generates human-like responses
• Improves accuracy over simple keyword matching

Traditional email search requires exact keyword matching and manual scanning of results. AI-powered search understands natural language queries and context, returning precise answers instantly. For example, asking 'What hotel did I book for Paris last summer?' would find the confirmation email even if you don't remember specific keywords.

In business contexts, this can save hours per week. A study by McKinsey found knowledge workers spend 19% of their time searching for information. This automation reduces that time to seconds while improving result accuracy.

• No need to remember exact phrases
• Understands dates and relative time
• Finds conceptually related content

The system excels at finding specific information buried in emails: travel details, purchase receipts, meeting notes, or academic records. It understands temporal queries ('last month'), comparative questions ('which option was cheaper'), and can summarize multiple related emails into a coherent answer.

For example, asking "Show me all software subscriptions renewing next month" would scan your emails for renewal notices and compile a list. Or "What was discussed in my last meeting with Acme Corp?" would find and summarize the relevant thread.

• Best for factual queries with clear answers
• Works well with date-based questions
• Can compare options from different emails

The workflow processes emails through secure API connections without storing raw data long-term. Pgvector stores only vector representations of content, not the actual emails. For maximum security, you can self-host the database and AI components rather than using cloud services.

Unlike commercial email assistants, this solution keeps your data under your control. The vector embeddings cannot be reverse-engineered to reveal original email content, providing an additional layer of privacy protection.

• No third-party access to email content
• Encrypted API connections
• Option for complete self-hosting

Yes, with additional configuration. The workflow can be extended to process common attachment types by extracting their text content. PDFs, Word docs, and spreadsheets can be indexed alongside email body text for comprehensive search capabilities.

This requires adding document processing steps to the workflow, such as OCR for scanned PDFs or text extraction from binary formats. The system can then treat attachment content the same way it processes email bodies for search and retrieval.

• Supports common document formats
• Requires additional processing steps
• Maintains same search quality for attachments

Telegram provides a familiar chat interface available across all devices, with built-in privacy controls. It allows conversational interactions with your email history from anywhere, without needing to open your email client. The bot can also send rich previews of found information.

The platform's robust API makes it ideal for automation workflows. You can create custom keyboards for common queries, set up alerts for important found information, and even share results with colleagues through Telegram's forwarding features.

• Available on mobile and desktop
• Supports rich media responses
• Enables conversational interactions
