📦 chatpack

Feed your chat history to LLMs. Compress exports 13x with CSV format.

Platforms: Windows • macOS • Linux

The Problem

You want to ask Claude/ChatGPT about your conversations, but:

• Raw exports are 80% metadata noise
• JSON structure wastes tokens on brackets and keys
• Context windows are expensive

The Solution

┌─────────────────┐     ┌──────────┐     ┌─────────────────┐
│ Telegram JSON   │     │          │     │ Clean CSV       │
│ WhatsApp TXT    │ ──▶ │ chatpack │ ──▶│ Ready for LLM   │
│ Instagram JSON  │     │          │     │ 13x less tokens │
└─────────────────┘     └──────────┘     └─────────────────┘

Real Numbers

💡 Use CSV for maximum token savings. JSONL is good for RAG pipelines. JSON keeps full structure but wastes tokens.
