As answered by people managing GitHub Surf and Quillo.tr.
Quillo.tr's answer:
Kotlin for Android, Swift for iOS, Next.js for the web, a Python server on Google Cloud, Google Gemini for natural voices and Anthropic Claude for Quillo Ai.
Quillo.tr's answer:
It combines a read-aloud app, an AI assistant and a full PDF toolkit in one library. Every Quillo Ai answer shows the page it came from, it turns notes into exams with answer keys, and it can be used fully by voice, which makes it work well for blind and low-vision users.
Quillo.tr's answer:
Instead of paying separately for a text-to-speech app, an AI PDF chat and a PDF editor, you get all three for one low price, and most PDF tools are free without an account. Your files stay on your device and in your own Google Drive; they are never stored on our servers.
Quillo.tr's answer:
Students and teachers, people who prefer listening to reading (including blind, low-vision and dyslexic users), and office workers who sign, stamp and send documents every day.
Quillo.tr's answer:
Quillo started in 2026 as a Turkish app that reads PDFs aloud, built by independent developer Agah Emre SÖZEN. It grew into an all-in-one document app for the web, Android and iPhone in four languages.
