File formats

PST and MBOX: the most common email formats

Your emails may be stored in PST (Outlook) or MBOX (Thunderbird, Gmail) files. Both contain valuable information, but they need to be converted to Markdown (.md) for your AI to use them.

📥

PST (Outlook)

The Personal Storage Table (.pst) format is used by Microsoft Outlook to store emails, contacts, calendars, and other items. It is a proprietary format that can contain years of business communication.

The problem

Your PST and MBOX files are a treasure... buried

You have years of information buried in mailboxes inside PST and MBOX files. But these formats are not compatible with modern AI systems. You need to extract the text and convert it to Markdown so your AI can access that knowledge.

📬

Inaccessible data

PST and MBOX files are not directly readable by AI models. They need to be processed and converted.

🧹

Noise and duplicates

Emails contain signatures, HTML, threads, and duplicates that degrade your AI's accuracy.

🧠

AI without context

Your RAG, ChatGPT, or NotebookLM cannot access the valuable information in your PST and MBOX files.
