Capsera

Capsera is a PWA that lets under-resourced innovators submit ideas privately, get instant AI feedback, and connect with mentors—all with low storage and soon offline access.

Inspiration

Millions of people have ideas but lack devices, storage, or stable internet. We wanted to give them a private, accessible way to share, refine, and elevate their ideas.

What it does

Capsera is a PWA where users create a private PIN account on a shared device, submit ideas via guided prompts, and get instant AI feedback + a rough score. Drafts are saved locally, and final submissions go to Supabase for review. Multilingual support (Arabic, French, Amharic, etc.) ensures inclusivity.

How we built it

  • Frontend: Vanilla JS + JavaScript + PWA setup
  • Backend: Supabase
  • APIs: OpenAI for feedback & scoring, Google Translate for language support

Challenges we ran into

  • Protecting environmental variables
  • Choosing the right tech stack
  • Managing PWA caching so updates show correctly

Accomplishments that we’re proud of

  • Successfully integrated environmental variables
  • Implemented founder and user feedback into the product
  • Built a working PWA that meets privacy and accessibility needs

What we learned

  • Sketching multiple designs helps teams innovate and identify missing features
  • Don’t get attached to any MVP; feedback will transform it
  • Prioritizing ideal customer needs over personal design preferences is crucial

What's next for Capsera

  • Make Capsera fully offline for low-bandwidth users
  • Gather beta tester feedback to improve or pivot the product
