Vocafy
A vocabulary trainer I built because Quizlet's learn mode kept getting it wrong.
- Role
- Solo: full-stack
- Period
- Since March 2023

Overview
Quizlet's learn mode marked answers wrong that weren't, and never made me rewrite the words I had actually got wrong.
So I built my own platform that fixes both. I developed, refined and tested Vocafy with friends over two and a half years.
Several friends use it regularly to study for exams, and I used it myself for two years to prepare for vocabulary tests.
What I do
- Designed the learning flow and the interface from scratch
- Node.js backend and MySQL database
- The landing page at vocafy.ch and the web app at app.vocafy.ch
- Hosting and running both on my own server

Tech
Full-stack without a framework
Plain HTML, CSS and JavaScript on the front, Node.js and MySQL behind it, all written by me.
Product
Solving my own problem
Built because the existing tool failed me, then used for two years of my own vocabulary tests.
Testing with real users
Refined over two and a half years with friends who studied for real exams with it.
Building something? Let's talk.
A project, a venture to build together, or a role to talk through. I read every message myself.
