If you're anything like me, your Amazon Kindle is less of a library and more of a digital graveyard. It's a place where good ideas, brilliant quotes, and profound insights go to die. You read a book, you highlight a passage that feels like a lightning bolt to the brain, and you think, "I'll definitely remember this."
And then… you don't. It vanishes into the ether, buried under a dozen other books and a thousand other highlights. It becomes digital dust. Every now and then, I get that nagging feeling—you know the one—"I know I read something brilliant about cognitive biases, but where was it?" I’d spend 20 minutes aimlessly flipping through my Kindle library, getting frustrated, and giving up. My intellectual breadcrumbs were scattered with no way to follow them home.
I’ve tried everything. Manually typing notes, using Amazon’s clunky online reader… nothing stuck. So when I stumbled upon a tool called Unearthed, my ears perked up. Another tool? Sure. But this one promised something different. It promised to be an archaeologist for my forgotten knowledge. And honestly, I was intrigued.
So, What Exactly Is Unearthed?
In simple terms, Unearthed is a bridge. It’s a bridge between the ideas you capture on your Kindle and the place you actually use those ideas—your second brain, your digital garden, your note-taking app of choice. It automatically syncs all your Kindle highlights and notes over to apps like Notion, Obsidian, Supernotes, and Capacities. But its not just a copy-paste machine.
Here's the kicker: it uses AI to analyze what you've read. It resurfaces old quotes as daily reflections, asks you thought-provoking questions about them, and even tries to spot your intellectual blind spots based on your reading patterns. It’s like having a little research assistant who knows you really, really well. Oh, and its open-source, which in a world of data-hungry tech giants, is a huge breath of fresh air for me.
The Features That Actually Matter (My Take)
I've tested a lot of tools in the productivity and PKM (Personal Knowledge Management) space, and most are bloated with features I'll never touch. Unearthed keeps it refreshingly focused. Here’s what stood out to me.
Automatic Kindle Sync (Without Giving Up Your Password)
This was the first thing that sold me. Unlike some other services, Unearthed doesn't ask for your Amazon login credentials. My security-conscious brain did a little happy dance. Instead, it uses a lightweight browser extension to do the sync. It’s a small, one-time setup that feels way more secure. Once it's running, it just works in the background, pulling in new highlights as you make them. Effortless.
The AI Magic: More Than Just a Clipboard
This is where things get fun. The daily reflections are a fantastic way to start the day. You get an email or a new note in your app with a highlight from your past. It’s a wonderful moment of serendipity. I’ll get a quote from a book I read three years ago and it’ll be exactly what I needed to hear that day. Spooky, but cool.
The premium version takes this even further. It can generate summaries, find common themes across your reading, and even let you “chat” with a book. Imagine asking a book, "What were your three main arguments against stoicism?" and getting a coherent answer based on your own highlights. We're living in the future, people. It also has a 'blind spot detection' feature that points out areas you might be neglecting in your reading. A bit humbling, but incredibly useful for anyone trying to get a more rounded perspective.
Integrations That Just Work
A tool like this lives or dies by its integrations. Unearthed nails it by connecting with the big players in the note-taking world. I'm a huge Obsidian user, and the way it syncs my notes, complete with book titles and authors, is just perfect. It seamlessly flows into my existing workflow. For all you Notion wizards out there, the Notion sync is a premium feature, but from what I’ve seen, it's a deep integration that many will find worth the price of admission.

Let's Talk Turkey: The Unearthed Pricing
Okay, the all-important question: how much does it cost? This is one of the best parts. Unearthed has one of the most generous free tiers I’ve ever seen. Seriously.
Here’s a quick breakdown I've pulled together:
| Plan | Price | Key Features |
|---|---|---|
| Free | $0 | Automatic Kindle Import, Daily Reflections, sync with Obsidian, Supernotes & Capacities. No character limits. It’s a powerhouse for free. |
| Premium | $5 / month | Everything in Free, PLUS: Notion Sync, AI Chat with Books, Book Summaries, Blind Spot Detection, Book Recommendations, Interactive Map, Manual Imports, and much more. |
My take? If you use Obsidian, Supernotes, or Capacities, the free plan is a no-brainer. You get the core functionality without paying a dime. If you are a die-hard Notion user or you’re really excited by the advanced AI analysis and book-chat features, the $5/month premium plan is an absolute steal. That's less than a fancy coffee for a tool that could genuinely change how you interact with everything you read.
The Good, The Bad, and The AI
No tool is perfect, right? So let's get into the nitty-gritty. I love the serendipity of rediscovering old notes and the fact that it's open-source gives me peace of mind. The automatic sync is the hero feature that solves the core problem beautifully. It just... works.
On the flip side, you have to be realistic about the AI. It's very, very good, but it's not a sentient being. Sometimes a daily reflection might feel a little random, or an AI-generated question might miss the point of your highlight. That’s okay. It’s a starting point for your own thinking, not a replacement for it. And yes, the fact that you need a browser extension might be a minor hurdle for some, but I see it as a positive for security.
Is Unearthed Right For You?
If you're a voracious reader, a student, a writer, or anyone who's bought into the 'second brain' philosophy, I think you'll find a ton of value here. It’s for people who feel that pang of regret when they forget a great idea. It’s for the knowledge hoarders who want to turn their hoard into an actual, usable treasure map.
Who isn't it for? If you only read a couple of books a year and rarely highlight, this is probably overkill. If you don't use a dedicated note-taking app, you won't get the full benefit. But if you're on the fence, the free version costs you nothing to try. Why not give it a shot?

It uses a secure browser extension that you install in your web browser. This extension can access the highlights when you visit the Amazon cloud reader website, without ever needing your private login details.

What about privacy?
The developers state it's built with transparency in mind. The fact that it's open-source means the code can be inspected by anyone, which provides a level of trust you don't get with closed-source, proprietary apps.
A Shovel for Your Digital Treasure Chest
At the end of the day, Unearthed solves a problem that has plagued me for years. It's turned my Kindle from a 'read-and-forget' device into an active part of my learning process. It’s a simple, elegant solution that acts as the shovel for the treasure chest of ideas I’d already buried.
It encourages a deeper, more continuous engagement with the books we read, long after we’ve turned the final page. And in a world of endless information, finding ways to truly absorb and connect with what we learn is more important than ever. For me, Unearthed isn’t just another app; it’s a new way of reading.
