A reading companion for the lifelong curious

Read toward what you don't know yet.

BookSeeking reads your books for what they actually teach — the ideas, people, places and eras inside them — then points you to the ones that widen your world instead of repeating it.

Bring five books or five hundred. Every reader has a sky worth mapping.
Not more of the same

Most apps recommend what you've already got. We recommend what you're missing.

Recommendation engines match on genre, author, and what other people bought — so a reader of four war histories gets a fifth. BookSeeking looks underneath the cover at the concepts a book teaches, and surfaces the titles that fill the gaps next to what you already know.

It's the difference between predicting what you'll click and helping you grow.

The dim star is the gap we'd fill next

What we'd recommend next
Man's Search for Meaning
Viktor Frankl

You've absorbed how the Stoics steadied themselves against fate. Frankl carries that same question into a 20th-century psychology of suffering and purpose — familiar in spirit, new in ground.

Four ways into everything you've read

Your library, seen four ways.

The same reading, mapped as a constellation of ideas, traced across time and place, measured by what you've mastered, and matched to the writers who share your mind.

Every idea your reading has touched, charted as a constellation — with lines to the concepts each book could lead you toward next.

Why it's different

Built like a librarian, not a billboard.

It reads for outcomes, not genres

We analyse what a book actually teaches — its concepts, people, places and eras — instead of filing it under a shelf label.

Anchored to a real taxonomy

Every concept is pinned to the Universal Decimal Classification, the international library standard — so matches are rigorous, not vibes.

Tuned to how you read

Pacing, voice, density, mood — BookSeeking learns the texture you enjoy, not just the topics, using Saricks's appeal factors.

Built to widen, not narrow

We optimise for your growth, not your screen time. Recommendations aim just past what you know — the readable edge of new.

Grounded in research

A recommendation is a small act of teaching.

Our matching is shaped by decades of work on curiosity, optimal challenge, and how readers actually grow — from Loewenstein's information gaps to Krashen's i + 1 to Saricks's appeal factors.

1994
Loewenstein — curiosity is a gap between what you know and don't
1985
Krashen — we learn best from material just beyond our level (i + 1)
—
Saricks — satisfaction comes from how a book reads, not only its subject
For every kind of reader

You don't need a big shelf. You just need to have read something you loved.

Mysteries, memoirs, cookbooks, physics, poetry — every genre teaches something, and BookSeeking treats them all the same way: by what they leave you knowing. Start with one book. The map grows with you.

Find your next book by the light of the last.
