There is an app called FocusReader which does exactly above using user provided chatgpt Api key. I dont want to use api rather authentication in browser since api costs. If app is foss its better. If no such app exist. I may learn app development and integrate this feature in Flym. If anyone has any alternative in mind, please suggest or if you have android app development experience, suggest after looking at the code at github how can i go about the development myself.
