DetailDetector

DetailDetector is a focused offline reasoning tool built around one cognitive move: noticing the missing detail that most changes what a short scenario means.

Each session gives you one intentionally incomplete scenario. You inspect the scenario, choose the omission that matters most, explain why it changes the judgment, compare the likely premature conclusion with the revised interpretation after the reveal, and save exactly one locked Critical Detail Card.<br><br>The app includes five distinct reasoning modes, bundled offline reasoning sets, a one-session-one-artifact workflow, locked Critical Detail Cards, revision lineage instead of direct editing, search and filtering, archive browsing, and local insights based on your own saved cards.

DetailDetector is fully local-only: no accounts, no ads, no tracking, no analytics, and no network features. It is not a trivia game, note app, journal, chat app, or prompt bank. It is a narrow omission-detection trainer designed to slow down premature judgment and make interpretation shifts visible.
