Ever picked up a bestselling Christian book only to discover — chapters in — that its theology doesn't quite line up with Scripture? TheoScope was built to solve that exact problem. It's an AI-powered tool that instantly scores any book on biblical faithfulness, theological depth, and doctrinal alignment, so you know what it teaches before it shapes your thinking.^1
Search by title or scan a barcode, and TheoScope returns a composite score (0–100) weighted toward biblical faithfulness, plus a full theological profile: where the book lands on the Progressive-to-Reformed spectrum, its doctrinal positions on Scripture, soteriology, ecclesiology, and eschatology, and audience fit ratings for adults, youth, and children separately.^1 It covers non-fiction, fiction (with content flags for language, violence, and mature themes), and even Bible translations — rating each for textual fidelity and evangelical trustworthiness.^1
Founded by Will Griffin, a pastor serving at Clayton Baptist Church in Clayton, Georgia, TheoScope grew out of a burden to get the right books into the right hands.^1 Griffin spent years wanting to vet every book his congregation read but never had enough hours to read them all. TheoScope gives pastors, parents, ministry leaders, and avid readers instant theological insight without requiring a seminary degree.^2
The scoring engine is AI-generated and supplemented by community ratings, creating a feedback loop that improves accuracy over time.^1 The app evaluates books across Christian traditions — Reformed, Arminian, Charismatic, Anglican, and more — scoring each on its own terms rather than flattening everything into a single lens.^2
