Build an App to Connect Ideas Across Books (2026)

If you’ve been searching for an app to connect ideas across books, you’ve probably noticed the generic reading apps don’t quite fit how you read. The good news: you can build your own quote organizer in Auto in a few minutes—tailored to your library, your themes, your way of thinking.

Why build it instead of downloading one

There are plenty of “best reading apps for book lovers” roundups out there, and some are genuinely good. If you just want a highlight vault, one of those might work fine.

But most people looking for an app for book lovers to organize notes eventually hit the same wall: the app organizes things its way, not yours. People even rebuild this manually—there are whole guides on using Notion for connecting book notes, which works but takes real setup and upkeep.

Auto skips that. You describe what you want, snap a photo of a page, and it builds you a personal mini-app (a “Frame”) around it. No code, no templates to wrangle, no settling.

Building your quote organizer in Auto

1. Open Auto and describe the Frame. Tell it you want a reading journal that turns a photo of a quote into an organized, searchable entry.
2. Set how it should categorize. Ask it to auto-tag each quote by genre and theme so your library sorts itself.
3. Ask for connections. This is the part generic apps miss—request that it link related ideas across different quotes and different books.
4. Snap and go. Photograph a page, and your Frame reads the quote, files it, and starts surfacing echoes between books.

Because you built it, you can tweak it anytime—add a “favorite passages” view, tag by author, or track which book each idea came from.

How someone built theirs

One Auto user wanted exactly this. They started by asking Auto to create a reading journal that automatically categorizes quotes from a photo by genre and theme, so they could track every book they read in one place.

Then they added the part that actually mattered to them: the ability to link ideas between different quotes—even across different books. That single instruction turned a plain highlight list into something closer to a personal web of thoughts, where a line from a novel might connect to an argument in a nonfiction title read months earlier.

You don’t have to copy their version. That’s the point—yours can emphasize whatever you care about most.

Proof people already build these

This isn’t hypothetical. Real Frames like Marginalia already exist, built by people who wanted their reading notes to talk to each other instead of sitting in silos. Yours would be its own Frame, shaped around your library.

FAQ

Do I need to know how to code? No. You describe what you want in plain language and snap photos. Auto builds the Frame.

Can it really connect ideas across different books? Yes—that’s a core request you can make when building it, so quotes from separate books surface as linked ideas.

How is this different from a note-taking app? A note app stores what you type. Your Auto Frame is built for your exact reading workflow: photo in, categorized and cross-linked quotes out.

How long does it take to build? Usually a few minutes—describe it, snap a page, and adjust from there.
