Architecture Story & Chat Polish

  • What changed:
  • Published the JainKosh architecture story as a PM-led technical case study explaining how the RAG pipeline, canonical guardrails, and answer quality system work under the hood.
  • Replaced the AI model powering chat across all surfaces — web widget, iOS, and Android — with DeepSeek V4 Flash, delivering faster responses at lower cost.
  • Fixed a visible chat quality issue: the AI was occasionally exposing its internal planning text ("We need to answer…", "Final check") in user-facing responses. This is now stripped before display.

Alert Quality & Scanner Tuning

  • What changed:
  • Cleaned up the alerting system to reduce noise. A stale browser-signature scanner was generating false-positive page-display alerts for pages that rendered correctly. Scanner filtering and priority guidelines were updated.
  • AI credit-monitoring guardrails (shipped Aug 11) continued to protect against provider-budget exhaustion by capping token usage per request.

Home Redesign, Global Search & Beta Release 60/33

  • What changed:
  • Redesigned the Home experience on iOS and Android: a content-first hub with doors into Video Lectures, Granths (scriptures), Kavya Kosh (poetry), and Study Notes — all loading natively in-app.
  • Global search launched across iOS and Android. Users can search JainKosh content from any screen.
  • First-run experience redesigned with a branded splash, onboarding flow, and clearer navigation.
  • Video Lectures got their own Home door, replacing the previous "Videos & Lectures" card.

  • Shipped internal beta builds iOS 60 (0.1.0) and Android 33 (0.4.1) to TestFlight and Play Internal Testing.
  • Our Books tab promoted to bottom navigation on both platforms, with corrected WhatsApp contact info.

Mobile Redesign (Builds 50–57) & QA Pass

  • What changed:
  • Complete visual redesign of the iOS and Android apps: faithful adaptation of Vikas Ji's 3a design direction with dawn-gradient headers, Noto Serif Devanagari typography, exact Material Symbols icons, and sandstone/orange palette.
  • Tab restructure: Calendar promoted to a dedicated tab; Learn moved into the More menu; Our Books promoted to bottom-nav.
  • Dark mode enabled on iOS with adaptive card surfaces.
  • Per-section language chip that remembers your preference (Hindi/Hinglish/English) per page.
  • In-app web views for Our Books availability — no more kicking users out to Safari.
  • Home Today strip now opens today's calendar detail directly (not the Ask tab or generic Calendar).
  • AI announcement overlays removed from the web chatbot — cleaner chat experience.
  • iOS Kavya Kosh and Study Notes added to Home with reader-mode support and dark-appearance fixes.
  • Android QA repairs: calendar highlighting, Ask composer behaviour, and Home→Ask handoff fixed.

Supabase Security & Product Direction

  • What changed:
  • Supabase data hardened: server-only RLS policies applied to prevent accidental client-side exposure of internal data.
  • Product direction documented based on Vikas Ji's detailed feedback: canonical mobile information architecture specified with Granths, Notes, Videos, Kaavya, Games, Classes, and Dictionary as core offering doors.

Home Tab, Dictionary & Audio (Builds 21–26)

  • What changed:
  • "Today" tab became "Home" — the central hub for the app experience.
  • Native Jain Dictionary launched on iOS and Android with Hindi-letter browsing and suggested terms.
  • Native audio lectures actually play now — fixed iOS audio session and Android media player.
  • Jain calendar moved into the More menu; dedicated Calendar tab dropped.
  • Global search groundwork laid (search endpoint and UI ready).

Answer Quality Breakthrough & Source Reference Fix

  • What changed:
  • Answer quality hit 100% (120/120) on the live evaluation benchmark — the RAG pipeline now consistently produces grounded, accurate, Digambar-aligned answers with proper source citations.
  • Wrong source references fixed: the chatbot was occasionally citing navigation pages or unrelated documents as evidence. New relevance gating, citation allowlisting, and ranked lexical retrieval solved this. Post-fix regrade showed a 7.1% strict wrong-reference rate.
  • Canonical answer guardrails strengthened: typo-tolerant matching (for voice input), roman-transliteration parity, and two-sided comparison handling.
  • OKF (Open Knowledge Framework) concepts classified and integrated — boundary Jain concepts now get properly routed answers instead of generic web results.
  • CI routing-eval gate added: every PR now runs the sect-conflict evaluation to catch regressions before merge.
  • Scheduled live-quality monitor runs daily to catch provider or pipeline degradation early.

Cloudflare Cutover & Third-Party APK Review

  • What changed:
  • Cloudflare protection attempted for jainkosh.org but rolled back: Bluehost proxy caching conflicts caused 409 reload challenges. Root cause identified and documented for future attempt.
  • Third-party APK review published: visual analysis of a reference Jain app to inform JainKosh mobile design direction.
  • Site-check panic button added for rapid health diagnosis when jainkosh.org has issues.

Answer Review Dashboard & Stability

  • What changed:
  • Answer review dashboard launched — volunteers (led by Vikas Ji) can now review chatbot answers, flag incorrect ones, and help improve quality. Passwordless by design for easy access.
  • Analytics dashboard password gate removed — now accessible to stakeholders directly.
  • 409 stability incident resolved: Bluehost proxy caching was causing reload loops for jainkosh.org visitors. Botnet UA rotation was exhausting server resources. Fixed with `.cpanel/proxy_conf` cache tuning and botnet filtering.
  • Site health observability expanded with fallback telemetry paths.

Native iOS & Android Apps, RAG Pipeline, Calendar

  • What changed:
  • Native iOS app built from scratch in Swift/SwiftUI: onboarding, AI Ask tab, Jain calendar, saved answers, voice input (behind feature flag), and JainKosh orange design palette.
  • Native Android app built in Kotlin/Jetpack Compose: full parity with iOS including calendar, Ask AI, learning resources, video guides, daily reflection, and push notifications.
  • RAG (Retrieval-Augmented Generation) pipeline went live: JainKosh AI now retrieves from a verified corpus of Jain scripture pages and PDFs instead of relying on general knowledge. Includes OCR for scanned PDFs, Digambar-centric retrieval weighting, and source citation requirements.
  • Jain Calendar launched on both platforms with Gregorian-to-tithi mapping using verified Digambar dates. Includes daily guidance (Dos & Don'ts) and food/fasting cues.
  • Web Push notifications completed: daily "आज का जैन चिंतन" push at 7 AM IST, with opt-in prompt, analytics funnel, and unsubscribe flow.

Web Chatbot Launch & Analytics

  • What changed:
  • AI chatbot widget launched on jainkosh.org via MediaWiki integration: users can ask Jain philosophy questions in Hindi, Hinglish, or English and get AI-powered answers with source citations.
  • Embedded widget polished with streaming responses, mobile-responsive layout, language switching, markdown rendering, and dark mode.
  • Answer quality guardrails: canonical Digambar grounding for sensitive topics (tirthankar marital status, sect-specific questions), fabricated-link prevention, and scope controls.
  • Chat history persists locally so conversations survive page reloads.
  • Follow-up question pills suggest next questions based on context.
  • Video recommendation integration: chatbot suggests exact JainKosh YouTube playlist links instead of generic channel URLs.
  • Feedback system: users can report issues or rate answers, feeding into the answer review pipeline.
  • Analytics dashboard launched with QA-aware filtering, question tracking, push notification funnel, site health monitoring, and IST-default timezone. Stakeholder reports separated from internal testing data.
  • Web Push notifications proof-of-concept shipped with daily Jain wisdom pushes, opt-in flow, and unsubscribe support.
  • Vikas Ji voice mode added for natural Hindi conversation style.

Project Origins

  • What happened before public release:
  • April 2026: Vikas Jain and Mohit began coordinating JainKosh hosting on Bluehost India. Domain jainkosh.org was already active as a MediaWiki-based Jain encyclopedia.
  • June 2, 2026: First recorded development commit — chatbot API switched to OpenRouter with Gemma-based models.
  • June 14, 2026: Mohitjain14 account set up on jainkosh.org; Vikas Ji marked it as a "good user" for MediaWiki access. Chatbot widget integration planning began.
  • June 15, 2026: JainKosh GitHub monorepo created with web app, embeddable widget, and PRD roadmap.
