- Daily 'three things to know' digest recapping each team's storyline
- Cross-league stat tracking so fans can compare NPB stars to MLB players
Trending searches for 'ジャイアンツtv' and Tigers coverage like Motoyama's breakout show Japanese baseball fans are hungry for richer, on-demand storytelling beyond the broadcast.
Giants and Tigers are NPB's two biggest brands with massive fandom; Giants TV is a real search term and both teams publish extensive digital content, but a lot of basic broadcast/alert demand is already served by official channels.ライブ | Giants Tv ↗読売ジャイアンツ（巨人軍）公式サイト ↗
Tight: the Hanshin Tigers official app already provides 試合速報, push alerts, news, digital tickets and fan club features, and Giants TV covers streaming + push. An AI narrative layer is genuine differentiation but only narrows an already crowded official-tooling space.阪神タイガース 公式アプリ 機能紹介｜ホーム｜阪神タイガース公式サイト ↗阪神タイガース公式アプリ - Google Play のアプリ ↗
Japanese baseball fans do pay — Giants TV subscriptions, Tigers fan club memberships, and DAZN NPB access are established — but stacking a third paywall on top of free official push alerts is a hard sell, especially for a text-summary product.ライブ | Giants Tv ↗阪神タイガース 公式アプリ 機能紹介｜ホーム｜阪神タイガース公式サイト ↗
NPB is a century-old institution with deeply loyal regional fandoms (Giants in Kanto, Tigers in Kansai); demand for both teams' coverage is structural and seasonal, not a fad.読売ジャイアンツ（巨人軍）公式サイト ↗阪神タイガース 公式アプリ 機能紹介｜ホーム｜阪神タイガース公式サイト ↗
LLM-based plain-language summarization is technically straightforward, but real-time play-by-play requires licensed data feeds (NPB/team rights), Japanese-language QA, and reliable low-latency push infrastructure — non-trivial outside an official partnership.一軍放送予定 | 読売ジャイアンツ（巨人軍）公式サイト ↗
