As answered by people managing Smallpdf and StudyKitHub.online.

StudyKitHub.online's answer:
Our primary audience is college and university students (ages 18-26), high school students, teachers, and lifelong learners. Currently our top users are from Pakistan, USA, India, UK, Canada, and Australia searching for reading time calculators, GPA to CGPA conversion, and citation generators. They are students who need quick, private, free tools without creating accounts or uploading sensitive assignment data.
StudyKitHub.online's answer:
StudyKit Hub was launched on Oct 19, 2026 by a student who was frustrated with existing tools that required logins, showed too many ads, and uploaded private notes to servers. I needed a simple hub for my own study - a place to organize notes, calculate GPA, and manage Pomodoro sessions. I built 13 tools that I used daily and made them free for everyone. Started with 0 impressions, now getting 100+ impressions daily organically. The goal is to become the most private alternative to TinyWow for students.
