After you finish a book, how much of it actually stays with you? Koham offers a different path: talk to your books instead of merely reading them. Import a book. Start a conversation. Back and forth, unhurried, like a late-night walk or an intimate chat in a quiet study. Koham will not help you speed-read, nor will it help you memorize more. It does one thing: it lets you converse with your books through AI, so that in the exchange, you come to know yourself. When true understanding arrives, you never forget. What you seek, you already are. --- Core Experience • Talk to Books: Ask any book what truly matters to you. Every response is grounded in the text. • Realtime Voice: Like calling an old friend. Speak, listen, interrupt, or simply pause in silence. • Your Bookshelf: Import your personal collection. Every book feels like an old friend. • Calm Reading: A quiet EPUB reader. Customize fonts, themes, and brightness as you like. • Thought Continuity: It remembers past discussions so you can pick up next time. View, edit, or delete memories anytime. --- Please Note • Koham does not include books. Please import your own EPUB files. • AI conversations require configuring your own API key in Settings, with step-by-step guidance in the app.

Verdict
The clearest difference is monetization model: Koham at free with in-app purchases against OnePage's paid. OnePage's advantage is update cadence (every 3 days vs weekly) and ratings volume (6 vs 1). On price, rating, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Koham sells 1 one-off in-app purchase and OnePage sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Koham against 5.0 for OnePage. That said, the two scores are not equally well evidenced: OnePage has 6 ratings behind it against 1, so its average is the more settled of the two.
Koham ships an update weekly, OnePage every 3 days. The most recent releases landed on October 31, 2026 and November 6, 2026 respectively.
