With the help of AI and ChatGPT-4, this app allows users to ask questions about PDFs or paper documents; it will only respond based on the document’s content. It contains Admob ads as well as in-app subscriptions to monetize the app. Users are asked to subscribe or watch ads whenever they run out of credits. Also, users need to subscribe if they want to upload PDFs that are larger than 20 pages. It’s very helpful for students and people whose work depends on PDFs. Check Demo from Here

The app is built in Kotlin, and it only uses the latest technologies, such as Jetpack Compose for the UI, which makes it very easy to add or update UI elements in the future.
