Features of LLMWhisperer

Layout Preservation: LLMWhisperer's layout-preserving mode retains the original structure of the document, including tables, paragraphs, multi-column layouts, etc., ensuring that the extracted data matches the original document.
Automatic Mode Switching: The tool can automatically recognize document types and switch between text mode and OCR mode. If the document is a scanned image or handwritten content, it automatically switches to OCR mode.
Form Element Recognition: LLMWhisperer can recognize checkboxes and radio buttons in PDF forms and present their values as raw text, making it easier for LLMs to understand.
Automatic Compression: When processing documents, LLMWhisperer can automatically compress unnecessary tokens, reducing processing time and cost while retaining key information.
Multilingual Support: LLMWhisperer supports over 300 languages and can process multilingual documents, including non-Latin scripts (such as Arabic, Chinese, Japanese, etc.).
Multiple Document Format Support: Supports PDF, images (JPEG, PNG, etc.), MS Office files (Word, Excel, PowerPoint), OpenDocument formats (ODT, ODP, ODS), and plain text files (TXT).

How to Use LLMWhisperer

API Integration: LLMWhisperer provides API interfaces that can be integrated into existing systems to enable automated document preprocessing.
Client Libraries: Users can install LLMWhisperer's client libraries (such as the Python llmwhisperer-client) to invoke its functionality.
Online Testing: LLMWhisperer offers an online Playground environment where users can upload documents for real-time testing without registering or installing any software.

Optimization Capabilities

Automatic Mode Switching: When processing documents, if the text mode extraction output is insufficient, it automatically switches to OCR mode.
Automatic Compression: Compresses markup that adds no value to the output while preserving layout, reducing LLM processing time and cost.
Preprocessing Control: Allows control over the preprocessing of scanned images, with parameters such as median filtering and Gaussian blur adjustable through the API.
