A reading tracker for thinkers

See what threads through
every book you read.

Most reading apps care what you finished and how many stars it got. Readbinder cares what each book said— and what every other book on your shelf said about the same idea.

The angle

One concept. Every author on your shelf.

Tag a theme on any book. Open the concept's page and read, in one place, what each author had to say about it.

← Concepts
karma

The idea that intentional action shapes future experience — treated very differently across the traditions you’ve been reading.

The Complete Book of YogaSwami Vivekananda

Karma is the discipline of action without attachment to the fruit — not fatalism, but the practice of acting fully without being owned by the outcome.

The KybalionThree Initiates

Frames cause and effect as a hermetic principle — less ethical, more mechanical. "Nothing escapes the law."

AnimismErnesto Bozzano

Treats karmic continuity as evidence for survival — the same intentional self carrying forward across lives.

What's in v1

A small, honest set of features.

Track every book

Status, dates, genre tags, cover, and markdown notes. Nothing social. No streaks. No gamification.

C

Tag concepts across books

A per-book note on each concept. The concept's page shows every author's take side by side.
