The camera icon allows you to use Optical Character Recognition (OCR) to upload text directly into the chat.
By tapping the icon, you can take a photo of any text you'd like to discuss. The app will then automatically convert the photographed text into editable text, which will appear in the chat window for further interaction.
For example, you could take a picture of the ingredients on a nutrition label, and ask Chatster to explain what each one is!
