Questions before you hand over your TBR.

Goodreads and StoryGraph help you record what you read. Read Between The Lines learns why books work—or do not work—for you, then uses those patterns to help you choose before you commit.

Reader DNA is a living picture of how you experience stories: what creates attachment, what breaks your trust, what kind of payoff satisfies you, and how those needs change over time. Every debrief makes it sharper.

Book Bestie is your reading companion inside Read Between The Lines—the one who remembers how books made you feel and uses those patterns to help you choose, screen and protect your reading time.

No. Popularity is not the same as compatibility. Book Bestie looks for the reading experience that fits you, even when the obvious or trending choice probably will not.

That is expected. Your Reader DNA remembers your lasting patterns; your current reading season helps Book Bestie understand what you need right now. Loving devastating fantasy does not mean you want devastation this week.

It’s what you’re craving right now—like feral obsession, cozy comfort or delicious devastation. You pick up to three when you sign up, and you can change them anytime on the “Current craving” card in My Reader DNA. Book Bestie also notices when your recent debriefs show your taste shifting. Your season steers screenings and picks toward what you need right now, while your lasting Reader DNA only changes when you approve it during Realignment.

Onboarding creates your starter DNA. Ratings, DNFs (books you did not finish), debriefs, changed opinions and unexpected favorites add context over time. Book Bestie looks for patterns without treating one reaction as a permanent rule.

Yes. Book Bestie explains what makes a book a promising fit for you, which parts connect with your Reader DNA, and anything that might affect your enjoyment. You get the reasons behind the recommendation, with spoilers tucked away.

Yes, and that’s only part of it. Your reading experience covers how a book will actually feel to read for you: what keeps you turning pages (romance, banter, twists, worldbuilding and more), how quickly the story rewards you, how the chapters move, and how much description and dialogue it has, matched against how you like to read and listen. Each screened book then gets a call (read it, listen to it, or either) with the reason.

Yes. Tidy My Shelf looks over your TBR and suggests books worth a second chance, books you’ve outgrown and reads that stalled, so your list shrinks to the right fits. It also checks for release news on books you’re waiting for. Nothing moves without your OK.

No. Screenings, picks and every conversation with Book Bestie keep endings, deaths and twists hidden. Spoiler details stay tucked away and only appear if you choose to open them.

Yes. Tell Book Bestie what you want to avoid or be warned about, and those boundaries are honored across screenings, picks and chats.

From sourced research, including publisher pages, retailers, audiobook listings and reader-review patterns. If a detail cannot be confirmed, it says unconfirmed rather than guessed.

Yes. Import your Goodreads or StoryGraph history or build your shelf inside the app, then ask Book Bestie to choose from your own TBR.

The standard membership is $12.99 a month with 30 research credits. Right now Read Between The Lines is in a small founding-reader beta, and joining needs an invitation. Founding readers get their first three months free, then $7.99 a month (instead of $12.99) for the rest of their first year. To ask for an invite, email [email protected]. See pricing.

It starts with a 7-day free trial that includes 5 research credits and importing up to 25 books. After that it’s $12.99 a month. Cancel anytime. Membership includes 30 research credits a month (screening a book Book Bestie hasn’t researched yet uses 1; finding a brand-new book off your shelf uses 2; books already researched, picks from your TBR and chats don’t use credits), and importing up to 250 current books from Goodreads or StoryGraph, with all your older reads saved to your reading history. Bigger libraries can add a one-time import of +100, +250 or +500 books. See pricing.
