ESL vocab building and confidence boosting website.
LingoSpark is a growing collection of interactive ESL tools designed to make learning English fun, fast, and engaging. I build small, practical apps for teachers and learners—vocab games, writing challenges, team activities, and creative practice tools that turn everyday lessons into something students actually enjoy.
What I am really proud of is the Writing Suite, the feature that allows students to practice their writing skills and expand their glossaries individually and at their own pace. It can also be used by teachers as support for their writing classes.
More new activities coming soon!
If you like the project, want to test the AI features or support further development, your coffee helps me keep improving the platform, implementing new ideas and making English learning more appealing, natural and meaningful for everyone.
