for very important little things.

Small tools for the things that won’t stay put — what you own, what you’re missing, and what you meant to write down before you forgot it.

Chainsaw Man, volumes 1 to 24

A working shelf. Choose a volume to put it on the shelf or take it off. Nothing is saved and nothing is sent anywhere.

Four still missing.

What this is

Kepu is one person making small, careful apps for problems they actually have. Not a studio, not a startup — just the tools that should already exist and somehow don’t.

The name is Thai: เก็บอยู่keeping.

Not kept, past tense, finished. Still keeping. Which is what a collection actually is: never done, always one volume short.

เก็บอยู่

Keeping

01 — Manga Shelf

Your manga collection shouldn’t require a very good memory. Kepu keeps your series, volumes and missing books in one place, so you can check what you have before accidentally buying volume 17 again.

Know what you own. Know what to buy next.

One real shelf, still going.

The Kepu collection view, a grid of manga covers including Haikyu!!, Honey Lemon Soda and Jujutsu Kaisen, each labelled with the next volume to buy.

Collection

Everything on the shelf.

Keep track of volumes, languages, publishers, owners and purchase details — without turning your collection into a spreadsheet-shaped hobby.

A Chainsaw Man series page in Kepu, showing volumes 1 to 20 marked as owned, volume 21 as next to buy, and 22 to 24 still missing.

Series

Every volume, accounted for.

Tap a volume to mark it bought. Add where you found it, when you bought it, and which edition it is. Thai titles sort correctly, which is harder than it sounds.

The Kepu shopping list, showing series with their missing volumes marked as dotted chips and the next volume to buy outlined in orange.

Shopping

Know what comes next.

See what’s missing, what’s next, and what you’ve been meaning to pick up — all in one list. So the next trip to the bookshop is slightly less confusing.

Questions, problems, little things?

If Manga Shelf is misbehaving, or you have a question, or you just want to point something out — there are two addresses. One person reads both, so an answer might take a day or two.

And then

There will be others.

Same idea, different little things. Nothing worth announcing yet — but the shelf was never going to be the only one.
