Document Preview

The Challenge

Legal professionals work with a wide range of file types—Word, PDF, Excel, PowerPoint, and scanned documents. Switching between tools just to preview files wastes time, breaks focus, and risks version confusion. Worse, some file types require downloading or third-party viewers just to see what’s inside.

How to Unplex

Unplex offers a built-in Document Preview module across all supported file types. Every document uploaded to a project is automatically prepared for AI processing: parsed, indexed, and structured for Large Language Model (LLM) interaction. Once prepared, it can be previewed directly inside Unplex—no external tools needed.

Technical Implementation

• Multi-Format Support: Compatible with DOCX, PDF, XLSX, PPTX, TXT, Emails and more
• Pre-Processing Pipeline: Files are automatically cleaned, parsed, and indexed upon upload
• LLM-Ready Structuring: Documents are optimized for contextual understanding and referencing by Unplex’s AI
• Secure Preview Rendering: All previews are displayed securely in-browser with no file downloads required

Looking Ahead

We’re extending Document Preview with annotation tools, redline comparison, and in-line clause navigation - so you can review and mark up documents as naturally as reading them.
