I don’t know of anything like a text file component, but you could use a command_line sensor to read a file, and a shell_command to write. Use templating to process what to read and write.

yes you can using a custom component at least this is possible.

CON_CONTEXT_PATH = '/config/custom_components/your_service/'
    with open(CON_CONTEXT_PATH + "file.txt", "a") as file:
                file.write("\n"+message + "\n"+response_text) #output to file
