Chatize is a browser-based assistant powered by ChatGPT that lets you chat with documents instead of manually scrolling through them. Upload a file or paste a link to quickly find key passages, extract data, and generate concise takeaways.
Supported formats
Chatize works with common document types and web content, including:
- Word (.docx)
- Excel (.xls)
- PowerPoint (.ppt)
- eBooks (.epub)
- Markdown (.md)
- Web pages via URL
How it works
After you add a document, you can ask questions in plain English—request an explanation of a section, a short summary, specific numbers, or a comparison between parts of the text. Chatize analyzes the content and responds in a chat format, helping you search and understand large files faster.
Free and no signup
The service is positioned as completely free and does not require registration or payment. It can be useful for one-off tasks as well as regular work with lengthy documents for students, researchers, and office teams.
