Shortform vs Sumizeit vs getAbstract: Which Is Actually Worth It?

Posted on 5/13/2026, 2:29:11 PM

If you've spent any time looking for a book summary app, you've probably narrowed it down to a handful of names. Three come up most often: Shortform, Sumizeit, and getAbstract. They all promise the same basic thing — the key ideas from non-fiction books, in less time than reading the whole thing — but they go about it in very different ways, charge very different prices, and are built for very different readers.

We'll be upfront: we make Sumizeit, and we think it's the right choice for most people. But "most people" is not "everyone," and the honest answer to the comparison question depends on what you actually want. This post walks through what each app does well, where each one falls short, and which one you should pick based on how you actually read.

The Quick Version

Before we dig in, here's the short version of where each app lands:

Shortform is for serious self-learners who want long, in-depth book guides with commentary and exercises. It's the most thorough — and the most expensive in terms of your time per book.

getAbstract is for business professionals and enterprise teams. It's the oldest, the most polished, and the most expensive in dollars. Its library is enormous and skews heavily toward business and management.

Sumizeit is for everyone else — the busy reader who wants the core ideas of a book in fifteen minutes or less, on their phone, in audio or text, without paying enterprise-level prices.

Now the longer version.

Shortform: The Heavyweight

Shortform's pitch is that other book summary apps are too shallow. A typical Blinkist summary, the argument goes, gives you the headline ideas but strips away the nuance that makes the book worth reading in the first place. Shortform's solution is to write much longer summaries — often forty to a hundred pages of structured notes per book, complete with commentary, cross-references to related books, and exercises.

What's good about it. If you actually have the time, Shortform summaries are excellent. They preserve the author's argument with real fidelity, the editorial commentary is often sharp, and the cross-linking between books builds something close to a personal knowledge graph. For people who want to use book summaries as a replacement for reading, rather than a supplement to it, Shortform is the most serious option on the market.

What's not so good. The depth is a feature, but it's also the trap. A Shortform summary can take 45 to 90 minutes to get through, which is significant — and at that point, you're spending half the time it would take to read a real book. The interface is text-heavy and audio support is limited compared to competitors. The pricing reflects the depth: Shortform is one of the more expensive options in the category, typically running well over $20 per month on a monthly plan, with annual plans bringing it down somewhat. If you read primarily during commutes or workouts, Shortform is probably not the right fit.

Who Shortform is for. Serious self-learners with significant reading time who want a single book-replacement product, are comfortable reading on a screen, and don't mind paying premium prices for premium depth.

getAbstract: The Enterprise Veteran

getAbstract has been around since 1999, which makes it the elder statesman of the category. Its core product is the classic ten-page, ten-minute summary — short enough to read on a coffee break, long enough to capture the actual argument of a business book. The library is enormous: more than twenty-five thousand summaries spanning books, articles, videos, podcasts, and TED talks, available in multiple languages.

What's good about it. The library is the headline feature. If you want to summarize a relatively obscure business book or a niche professional title, getAbstract is likely to have it when other apps don't. The summaries themselves are well-edited and professionally written — there's a consistency of voice and quality that comes from twenty-plus years of doing the same thing. getAbstract is also the strongest option for enterprise use; many large corporations license it for their employees as part of internal learning programs, and the platform has features (team management, learning paths, analytics) built for that audience.

What's not so good. Two things stand out. The first is price: getAbstract's individual plan is one of the most expensive on the market, often running over $300 per year for a full subscription. The second is positioning. The library skews heavily toward business, management, and corporate self-development — useful if that's what you want, but limiting if you're looking for memoir, history, science, or general non-fiction. The mobile experience is functional but not as polished as newer competitors, and the brand voice tends toward corporate rather than conversational.

Who getAbstract is for. Business professionals whose employers pay for it, executives building a regular reading habit on a corporate development budget, and learners who specifically want a business-heavy library and don't mind paying premium prices.

Sumizeit: The Modern Alternative

Sumizeit was built around a specific observation: most people who want book summaries don't want forty pages of editorial commentary, and they don't want to pay enterprise prices for a corporate library. They want the ideas of a good book, fast, on their phone, in a format that fits into a commute or a lunch break — and at a price that doesn't make them think twice about subscribing.

So that's what we built.

What's good about it. Sumizeit summaries are designed to be read in about fifteen minutes or listened to in about the same. The library covers the books people actually want to read — bestsellers in self-help, business, productivity, psychology, and biography, with new titles added regularly. Every summary comes with high-quality audio, so you can listen on a commute, during a workout, or while making dinner. The mobile app is fast, clean, and designed for the way most people actually consume content: in fragments, between other things.

The pricing is the part most people notice. Sumizeit is significantly more affordable than both Shortform and getAbstract — at a fraction of getAbstract's annual price and well below Shortform's monthly cost. We made that choice deliberately. The point of a book summary app, in our view, is to remove the friction between you and the next idea worth thinking about. A subscription you have to justify every month is friction. We'd rather charge less and have you actually use it.

What's not so good. Honesty requires us to name the trade-offs. Sumizeit summaries are not forty pages long, which means if you specifically want exhaustive commentary or detailed exercises with each book, Shortform will go deeper than we do. Our library is curated rather than exhaustive — we focus on the books most readers actually want, which means if you're looking for a specific niche business title from 2008, getAbstract is more likely to have it. We're not built to replace reading every book; we're built to help you finish more of them, faster, and decide which ones are worth the deeper investment.

Who Sumizeit is for. Busy professionals, lifelong learners, students, founders, parents, and anyone else who wants more ideas in less time — without committing to forty-minute summaries or paying corporate-tier prices for the privilege.

Side-By-Side: How They Actually Compare

Here's how the three apps stack up across the dimensions most readers care about.

Summary length. Shortform is the longest by a wide margin — typically 30 to 100+ pages per book. getAbstract sits in the middle with its standard 10-page format. Sumizeit is the shortest of the three, with summaries designed for a 15-minute read.

Time per book. Shortform: 45–90 minutes. getAbstract: 10–15 minutes. Sumizeit: about 15 minutes, in either text or audio.

Audio. Sumizeit treats audio as a first-class feature — every summary is professionally narrated, designed for hands-free listening. getAbstract offers audio on many but not all summaries. Shortform has audio but it is generally less central to the product experience.

Library size. getAbstract is the largest by raw count (25,000+ titles, including articles and videos). Shortform's library is smaller but deeper per title. Sumizeit's library is curated — focused on the bestsellers and high-impact titles most readers actually want, rather than exhaustive coverage.

Library focus. getAbstract skews heavily business. Shortform skews self-improvement, psychology, and applied non-fiction. Sumizeit covers the broadest range across self-help, business, productivity, psychology, biography, and ideas.

Pricing. From least to most expensive: Sumizeit, then Shortform, then getAbstract. The price gap between Sumizeit and getAbstract in particular is substantial — often three to four times the annual cost.

Best for. Shortform: deep dives. getAbstract: enterprise and business specialists. Sumizeit: everyone who wants the core ideas, fast, on the go, at a fair price.

So Which One Should You Actually Pick?

The honest verdict depends on three questions about how you read.

If your goal is to replace reading entire books, and you have plenty of focused reading time: Shortform is the right choice. It is the only product in the category designed to substitute for the experience of working through a book in depth, and the editorial layer adds real value if you'll use it.

If your employer is paying, or you specifically need a business-heavy library with enterprise features: getAbstract is the obvious fit. It has been doing this longer than anyone else, the corporate tooling is mature, and the library breadth is unmatched within its niche.

If you're like most readers — you want the key ideas of good books, you want to read or listen during the in-between moments of a busy life, and you don't want to spend $300+ a year for the privilege — Sumizeit is the right choice. It's built for the way people actually consume content in 2026: on a phone, in short sessions, with audio for the hands-full moments, at a price that doesn't make you cancel after the third month.

Why Most Readers End Up at Sumizeit

The reason we built Sumizeit the way we did is that the original promise of book summary apps — "read more, in less time" — got distorted somewhere along the way. Shortform pushed the category toward longer, deeper summaries that take almost as long as reading the book. getAbstract pushed it toward enterprise pricing and corporate libraries. Both are legitimate products. Neither is what a busy person actually needs at the end of a long workday.

Sumizeit is what a busy person actually needs. Fifteen-minute summaries you can finish on a single commute. Audio so good you forget you're listening to a summary. A library that covers the books your friends are actually talking about. A price that pays for itself the first time you use it on a Tuesday morning instead of scrolling.

If you've been on the fence about which book summary app to try, the simplest advice we can offer is this: start with the cheapest, fastest, easiest option, and see whether the habit sticks. If you find yourself wanting deeper summaries six months in, you can always upgrade to Shortform later. If you find yourself wanting corporate features, getAbstract will still be there.

But most people, when they actually start using a summary app regularly, discover that the right amount of summary is less than they thought. The point isn't to read forty pages about a book. The point is to encounter one good idea, today, that you can carry into the rest of your week.

Try Sumizeit free and see whether the habit sticks. We think it will.
