Shellf vs Goodreads

This is the category I care about most, and the reason Shellf exists. Goodreads has more reading data than any app on earth — 150 million users’ worth of ratings, reviews, and reading history. And they consistently waste it.

Goodreads’ recommendations run on collaborative filtering: ‘readers who liked X also liked Y.’ That sounds reasonable until you realise it just surfaces popular books. If you’ve read 200 books in a genre, you don’t need to be told about the genre’s bestsellers — you’ve already read them. You need the books you haven’t found yet, the ones that match something specific about your taste that genre labels can’t capture.

Shellf’s recommendation engine uses embeddings — essentially mapping every book into a high-dimensional taste space — combined with LLM reasoning. It doesn’t just know you like fantasy; it learns that you gravitate toward unreliable narrators, slow-burn character development, and morally grey protagonists. The more books you rate, the sharper it gets. I’ve found that readers with 30+ rated books start getting suggestions that genuinely surprise them, with explanations for why they might connect.

I’ll be honest: if you have fewer than 15 rated books, Goodreads’ popularity-based approach might actually surface more useful results simply because it has a larger pool to draw from. Shellf’s AI needs data to work with. But once you’ve built a meaningful library, the quality gap becomes obvious.

This isn’t even close, and I won’t pretend otherwise. Goodreads has 150 million users, millions of reviews, reading groups, author Q&As, and the Reading Challenge that drives engagement every January. If community discussion is a core part of your reading life, Goodreads is the only real option on this list.

Shellf has no social features — deliberately. I’m not building a social network; I’m building a personal discovery tool. No public profiles, no followers, no social feed. That’s not a limitation we’re ashamed of; it’s a design decision. But I understand it’s a dealbreaker for readers who want to discuss books with friends, follow reviewers, or participate in group reads.

That said, Goodreads’ community has real problems. Review bombing has become frequent — books accumulate one-star ratings from people who haven’t read them, often as harassment campaigns against authors. Moderation is notoriously weak. Amazon removed direct messaging between members, which broke group moderation workflows. I see on Reddit that many long-time users feel the community peaked years ago and is now coasting on network effects rather than genuine quality.

The honest answer: if you want social reading, use Goodreads (or Fable for structured book clubs, or StoryGraph for a smaller but less toxic community). If you want a private space focused on your own taste and discovery, that’s what Shellf is built for.

Goodreads gives you the basics: books read this year, pages read, your annual reading challenge progress, and some simple genre breakdowns. It’s functional. It’s also exactly what it looked like in 2014.

Shellf takes a different approach to stats. Beyond the standard metrics (books read, pages read, monthly trends), you get genre breakdowns, fiction vs non-fiction splits, and a taste fingerprint that shows what themes and qualities you gravitate toward. Shellf Plus adds AI-generated reader insights — connections between your favourites, patterns in what resonates with you, and analysis of how your taste has evolved over time.

I’d like to think Shellf’s reading stats are up there with the market leader on stats (StoryGraph). But compared to Goodreads specifically, Shellf gives you meaningfully more insight into your reading patterns. The difference is that Goodreads tells you what you read; Shellf tries to tell you what your reading reveals about you.

Goodreads’ interface feels like 2011 because it largely is. Amazon acquired the platform in 2013 and meaningful design investment stopped. They refreshed the logo in mid-2025 — their first visual update in 20 years — but the core experience is unchanged. Dense text layouts, no dark mode on iOS or desktop, cluttered navigation, and an Android app that users consistently describe as buggy and outdated.

Shellf was designed dark-first with a bookshelf visual metaphor. The aesthetic is deliberately premium and literary — think dark wood and warm lighting rather than bright white cards. Your library appears as a visual bookshelf, not a flat list. Custom shelves use tag-based rules (any/all matching). Half-star ratings let you distinguish between a 3.5 and a 4. Notes support voice dictation. DNF tracking includes reasons, so you can remember why you dropped something.

This is obviously subjective territory. Some readers prefer Goodreads’ information density — you can see more data on a single screen. And Goodreads’ web app gives you a desktop experience that Shellf simply doesn’t offer yet. But in terms of modern mobile design, Shellf is what I wish Goodreads had evolved into.

Goodreads is completely free. Every feature, no paywall, no premium tier. That’s a genuine advantage and I won’t downplay it. Amazon subsidises Goodreads because it drives book purchases on their platform — your reading data is the product.

Shellf has a generous free plan: unlimited book tracking, full library organisation, reading stats, and 100 AI recommendation credits (enough for months of discovery). No time limit, no credit card required. Shellf Plus at $18/year unlocks 2,000 AI recommendation credits, advanced reader insights, and a few nice priority features.

To be honest though, my hope with Shellf is that I can eliminate the Plus plan at some point and make it completely free. Running software is super cheap now. The main reason I have a Plus plan at all is for 2 main reasons: it’s a safeguard from people over-consuming AI credits, and at $18 a year it helps with maintenance costs. The intention is to make sufficient income from people just buying books they discover through the app to cover the costs of running the business.

At $18/year, Shellf Plus is the cheapest premium tier of any book tracking app. I’ve tried to make the price a ‘no brainer’. It’s 64% less than StoryGraph Plus ($49.99/year) and 74% less than Fable Premium ($69.99/year). But free will always beat cheap for users who don’t need AI recommendations.

The honest question is: do you read enough to benefit from AI recommendations and AI insights? If you’re a casual reader — less than 10 books a year, mostly popular stuff — Shellf might be unnecessary and Goodreads does everything you need.

This is the angle that doesn’t get discussed enough. Goodreads is Amazon. Your reading data — what you read, what you rate, what you browse, how long you spend on each page — feeds into Amazon’s broader data ecosystem. Goodreads reviews appear on Amazon product pages. Kindle purchases sync to your Goodreads account. The whole pipeline from ‘discover a book’ to ‘buy it in one tap’ is Amazon’s acquisition funnel, and your data is the fuel.

For many readers, that’s fine. The Kindle-Goodreads integration is genuinely convenient, and if you already live in Amazon’s ecosystem, the data sharing is a feature, not a bug.

For others, it’s a dealbreaker. Shellf is independently owned. No corporate parent, no data sharing with retailers, no advertising, no tracking pixels. Your reading data is used for one thing: making your recommendations better. That’s it. I built Shellf as the tool I wanted for my wife — not as a data pipeline for someone else’s business.

If you’re considering the switch, the good news is it’s painless. Shellf supports direct Goodreads import via OAuth — sign in with your Goodreads credentials, and your books, ratings, shelves, and reading dates transfer automatically. No CSV wrangling required.

If you prefer not to connect your Goodreads account, you can also export a CSV from Goodreads and import it into Shellf manually. Either way, most users complete the process in under two minutes.

One thing I’d recommend: you don’t have to choose. Many readers keep their Goodreads account for the community and reviews while using Shellf for discovery and personal tracking. There’s no rule that says you can only use one app. Use Goodreads for what it’s best at (community reviews, book clubs, Kindle integration) and Shellf for what it’s best at (AI recommendations, modern UX, privacy).
