A private catalogue for fountain pens & inks

Your fountain pen collection nest.

NibNest is a place to keep what you own, note what you've inked, and remember how it wrote. No streaks. No badges. No feed. Only a quiet ledger — your collection, attended to with the care it was purchased for.

The four parts

Pens, inks, rotation, history. Nothing else.

Each does one thing, and does it well.

The Cabinet

Every pen you own, catalogued like a case file — brand, model, nib, material, a little room for remarks.

The Apothecary

Inks arranged by color, brand, and bottle. A true swatch wall, without smearing your desk.

The Rotation

Which ink is in which pen, right now. The page you'll open most often.

The Log

Every pairing you've ever made, remembered as a soft ribbon of history you can filter and flip through.

The hero move

Rotation, at a glance.

Each pen in rotation gets a card — pen on the left, ink on the right, the ink's color along the bottom.

Six more things, kept in reserve.

Drafted, not yet bound. We'll add these with the same restraint.

An AI amanuensis

Add pens by forwarding a receipt. No prompts required.

Import & export

Take your ledger with you, in every direction.

003

A private showcase

Share one plate, or the whole cabinet — on your terms.

004

The marketplace

Pass a pen on, to someone who will keep writing with it.

005

Community notes

Reviews, without the shouting.

006

A quiet value ledger

What you paid; what it's worth — for those who wonder.

An invitation

Begin your ledger. Write the rest, slowly.

NibNest is free to try. No feed, no streaks, no notifications. A small window onto a private desk.
