About this app

A bookshelf management app for people who use books as tools for work and study.

Researchers, graduate students, those aiming for certifications, writers, editors—
For those who repeatedly buy, use, and discard books for work and learning.

Existing apps are either "reading record SNS" or "manual input management tools."
Passim is different. A practical, work-focused bookshelf management app for people who use books as tools.

━━━━━━━━━━━━━━━━━━━

◆ Register in 3 seconds

Simply scan the barcode to automatically retrieve book information.

Take a picture of your bookshelf with your smartphone, and the AI ​​will read the spines and register them all at once.

No more manual input required.

◆ Organize by project

Thesis writing, certification studies, new business research, serial projects—

Link books to each project to keep track of what you've read and how far you've progressed.

You can also leave reference notes (e.g., "p.142-155 Chapter 3 is the core").

◆ Know Where It Is

Home, Lab, Parents' House, Warehouse, Currently on Loan.

Record the current location of your books to eliminate the "Where did I put that book?" problem.

Track missing books with the "Searching" status.

◆ Keep a Record of Letting Go

Sell, Donate, Dispose of, Transfer. Passsim records the history of books you've let go of.

Manage listings on flea market apps like Mercari, Rakuma, and Yahoo! Auctions.

It can even answer the question, "Did I own this book before?"

Automatic tag generation and one-line summaries. AI handles the tedious task of classification.

With the Pro plan, you can search across your collection with fuzzy searches, such as "Easy-to-Read Mysteries."
