Gemini
Best for structured reading paths and nonfiction curricula. Organizes books into genuine learning progressions and accurately describes what each title covers and what it lacks.
結果元: Gemini 2.0 Flash · テスト済み Feb 15, 2026ChatGPT
Strongest for practical reading logistics — page counts, audiobook lengths, and time-based recommendations. Handles emotional reading needs like comfort reads and mood matching well.
結果元: GPT-4o · テスト済み Feb 15, 2026Claude
Deepest literary taste analysis and most sophisticated discussion questions. Identifies subtle patterns in reading preferences and recommends books for their craft, not just their topic.
結果元: Claude 3.5 Sonnet · テスト済み Feb 15, 2026Grok
Strong on sci-fi, non-fiction, and unconventional book picks with genuinely opinionated reviews. Willing to call out overhyped bestsellers, but less comprehensive on literary fiction and academic recommendations than Claude.
結果元: Grok 2 · テスト済み Feb 15, 2026Tell the AI what you abandoned, not just what you loved. DNF (did-not-finish) books are gold for AI recommendations. They reveal your dealbreakers — slow pacing, unreliable narrators, or dense prose — more clearly than your favorites do.
Specify the format you'll actually use. A dense 600-page history book might be perfect on Kindle but terrible as an audiobook. Tell AI your format so it recommends books that work in how you'll actually consume them.
Ask for one book, not ten. Long recommendation lists create decision paralysis. Ask AI for THE single best book for you right now, with a clear reason why. You can always come back for more.
