Killedar: a fort guide that works where the signal dies
This is a submission for the Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass What I Built Try it: killedar.onrender.com · Code: github.com/abhijeetkaze/killedar Halfway up Rajgad the bars on your phone go one by one.

Killedar is an offline trek companion app designed to help trekkers navigate Maratha forts near Pune, such as Sinhagad, Rajgad, and Lohagad, when they lose signal on their journey. Created by Abhijeet Kaze, the app functions as a Progressive Web App (PWA) with three screens: Plan, Ask, and Listen.
On the Plan screen, users select a fort and trail, and enter the last bus back from the base village. Killedar then predicts the climb time based on the user's past hikes and works backward from the last bus to determine the ideal departure time from Pune. The Ask screen allows users to ask questions about the fort, such as whether there is water at a specific location or if a particular route is suitable for beginners.
The app answers these queries using Gemma, an on-device language model powered by WebLLM, which compiles models to WebGPU.
The Listen screen provides an audio narration of the fort's history, read aloud in either English or Marathi, allowing trekkers to engage with the fort's story even when their device's screen is inaccessible. To use Killedar offline, users must set it up once using their laptop or desktop computer before heading to the fort. Once set up, the app can function seamlessly with the airplane mode enabled, making it an ideal companion for trekkers who need reliable information while venturing through the Sahyadri forts.
