What’s new.

A dated, newest-first log of the tools, product improvements and infrastructure behind ThunderStudy AI, a seven-tool hub for study, exam preparation and everyday support.

Latest

Added

  • robots.txt and sitemap.xml for search engines, with AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended) allowed
  • llms.txt and llms-full.txt so AI assistants can understand the site
  • manifest.json and app icons (icons/icon-192.png, icons/icon-512.png) so the site can be installed as an app
  • sw.js service worker: caches the app shell, network-first for pages, cache-first for assets, and shows the offline page without a connection
  • offline.html, a “You are offline” page with a Retry button
  • about.html, faq.html and this changelog (new.html)
  • A clearer seven-tool AI hub: AI Chatbot Study, AI Mindmap, AI Flashcard, AI Mock Test Maker, AI Formula Sheet, Tiny AI Chat and Self Care AI
  • _headers (security headers and cache rules) and _redirects (clean URL redirects) for Cloudflare Pages
  • .well-known/security.txt, ads.txt and humans.txt
  • IndexNow support: a key file in the site root and indexnow-submit.sh to notify search engines of new URLs

Fixed

  • app.html header now shows the page links and the mobile menu, like the other pages

Improved

  • Header and footer navigation now link to About, FAQ and Changelog, and the footer shows the contact email
  • The About link in the header now opens the new about.html page
  • Every page now links the web app manifest and registers the service worker
  • About and changelog copy now describe the full seven-tool AI hub, while the CBT mock test remains the main exam-practice entry point

Removed

  • The background square in favicon.svg and the filled box behind the logo in every header and footer, so the logo sits on a transparent background
