# Current Limitations

> Current limitations for GC AI for Word

GC AI for Word includes web research and slide generation, along with tools for reviewing and editing the document open in Word. The following limitations still apply.

### File Format Support

* **Only `.docx` files are supported:** GC AI for Word requires Microsoft Word `.docx` format. Legacy `.doc` files are not supported and must be converted to `.docx` before use.
  * To convert `.doc` files to `.docx`, follow [Microsoft's conversion guide](https://support.microsoft.com/en-us/office/saving-doc-to-docx-or-dorm-0107099d-dc1e-4897-8851-f8c9f483f7cd).
* **PDF Conversion Issues:** PDFs that have been converted to `.docx` files may result in formatting issues or unexpected behavior due to the conversion process.

### General Usage

* As with any generative AI tool, double check outputs as hallucinations and errors can occur.
* Always verify legal accuracy and implications before sending client communications.
* Errors can occur while applying redlines and comments.
* Changing the formatting text can disrupt the output responses of the tool.

### Context Window

A [context window](/docs/chat/context-window) refers to the amount of text that the AI can analyze and consider at one time when processing your questions or requests.

* **Document Scope:** GC AI uses the open document as context, subject to the model's context window. For very large documents, use focused prompts or select the relevant text.
* **Complex Formatting:** While the add-in preserves most formatting, complex layouts, tables, and embedded objects may not be perfectly interpreted or replicated in the AI's suggestions and modifications.

### Feature Limitations

* **Open Documents:** GC AI works with one open Word document at a time. You can attach other files or select a project for more context.
* **Document Formatting:** You can format the document manually, but GC AI cannot reformat it in Word.
