In June, Filibot moved from imagination to implementation. The student team brought their ideas to life by designing, prototyping, and testing games like Space Trivia, while learning to balance fun with educational depth. Through trial, feedback, and iteration, June became a milestone in developing Filibot's playful, skill-based learning tools.
In May, the Filibot project took its very first steps as a student-led innovation in education. A diverse team of learners from across India came together with a shared dream: to build a playful, purposeful, and tech-powered learning platform for grassroots schools. Through brainstorming sessions, hands-on science activities, and the early development of their flagship game Space Trivia, the team laid the foundation for an ecosystem that blends learning with joy. Guided by mentors and united by vision, May was the month where curiosity met creation — and Filibot came to life.
In August the Alankrita student team moved design into action. First, students sketched new products. They designed small bags, earrings, pendants, and accessory sets. Each design followed the moodboard and regional palettes from July. The team also listed materials and estimated production time for every sketch. Next, the artisan prepared sample lists. The students prioritized […]
July 2025 — Alankrita opened an artisan hub in Halisahar, hired an artisan, onboarded two Filix students, and began aesthetics analytics, mapping regional colour palettes, motifs and photo styles.
In June the Alankrita student team moved from learning to doing. Four students — Ruthvik, Tanish, Gurnoor, and Pragya — created a moodboard, a short brand guide, SOPs, logo files, and two packaging concepts. These assets will make product photos, listings, and packaging look consistent and professional.
May was the first month of the Alankrita project. Four students — Ruthvik, Tanish, Gurnoor, and Pragya — joined the project to learn how the business works. The team spent May reviewing the brand’s data: product images, the sales register, and customer details. They also studied product-making steps and how orders are recorded to understand […]
