About Treecampus

The free english speaking course app from Treecampus was built specifically for learners who need to practice beyond classroom hours, on their own schedule, often without reliable internet access. The app works offline for core lessons and pairs that flexibility with an AI tutor named Treeacher, available around the clock for instant pronunciation and grammar feedback. Content spans more than 200 videos and text-based lessons, structured across a 90-day curriculum that moves from basic vocabulary to full conversational fluency. Every module is offered bilingually in Hindi and Bengali alongside English, ensuring learners aren't excluded simply because they haven't mastered English yet. Since its founding in 2013, this Kolkata-based, Section 8 registered non-profit has grown to more than 150,000 app installs, serving learners across 230+ cities and 20+ countries.
