Kairos — Fellowship Builder for Nepali Churches

BishalSunuwar202 — Mon, 02 Mar 2026 10:24:46 +0000

This is a submission for the DEV Weekend Challenge: Community

The Community

Nepal has thousands of small Christian fellowship churches — most run entirely by volunteers with no technical background. Every Saturday, a church anchor (presenter) manually types out the week's presentation: song lyrics in Nepali, Bible verses, sermon details, announcements, and prayer points — usually in PowerPoint.

What I Built

Kairos — Fellowship Builder is an AI-powered church presentation builder designed specifically for Nepali Christian communities.

An anchor fills in a simple form:

Fellowship date
Anchor name and sermon leader
Song lyrics (fetched automatically from a Nepali Christian songs library)
Bible references
Announcements and prayer points

How I Built It

Tech stack:

Framework - Next.js 16 (App Router)
AI - Gemini 2.5 Flash Lite via Vercel AI SDK (@ai-sdk/google)
Database & Auth - Supabase (PostgreSQL + Google OAuth)
Styling - Tailwind CSS v4 + shadcn/ui
State - Zustand
Deployment - Vercel

How the AI works:

The form data is sent to a Next.js API route which calls Gemini 2.5 Flash Lite with a carefully engineered system prompt. The prompt instructs the AI to:

Output only valid JSON (no markdown)
Write all slide content in Nepali Devanagari
Transliterate English names into Devanagari
Convert the Gregorian fellowship date into Bikram Sambat calendar in Nepali
Generate a warm, faith-appropriate welcome message in Nepali
Split song lyrics into individual slides per section (Verse 1, Chorus, Bridge, etc.)
Follow a fixed slide order: welcome → host → opening prayer → lyrics → sermon → Bible → announcements → closing prayer
Why Gemini 2.5 Flash Lite:
It handles Nepali Devanagari script accurately, understands Bikram Sambat calendar conversion, and is fast enough for real-time generation of 10–15 slides.

The biggest challenge:
Getting the AI to reliably output parseable JSON while also handling Nepali script, calendar conversion, and name transliteration all in a single prompt. The solution was using generateText (not streaming) and stripping any markdown code fences from the response before parsing.

This was built to solve a real problem for a real community — and it's already being used.
