+- 🍭**Custom-build document understanding engine.** Our deep learning engine is made according to the needs of analyzing and searching various type of documents in different domain.
   - For documents from different domain for different purpose, the engine applys different analyzing and search strategy.
   - Easily intervene and manipulate the data proccessing procedure when things goes beyond expectation.
   - Multi-media document understanding is supported using OCR and multi-modal LLM. 
-- **State-of-the-art table structure and layout recognition.** Precisely extract and understand the document including table content. See [README.](./deepdoc/README.md)
+- 🍭**State-of-the-art table structure and layout recognition.** Precisely extract and understand the document including table content. See [README.](./deepdoc/README.md)
   - For PDF files, layout and table structures including row, column and span of them are recognized.
   - Put the table accrossing the pages together.
   - Reconstruct the table structure components into html table.  
 - **Querying database dumped data are supported.** After uploading tables from any database, you can search any data records just by asking.
-  - Instead of using SQL to query a database, every one cat get the wanted data just by asking using natrual language.
-  - The record number uploaded is not limited.
-  - Some extra description of column headers should be provided.  
+  - You can now query a database using natural language instead of using SQL.
+  - The record number uploaded is not limited. 
 - **Reasoned and well-founded answers.** The cited document part in LLM's answer is provided and pointed out in the original document.
-  - The answers are based on retrieved result for which we apply vector-keyword hybrids search and rerank.
