The rotation problem
Uncap, squint at the feed, write a mystery line on scrap paper. Was it Kon-peki? Tsuki-yo? You genuinely cannot tell, and the bottle's long back on the shelf.
Everyone tries the dedicated logbook next to the inking station. Everyone stops by week three. The system that requires discipline is the system that fails.
The one you forgot was inked — three months ago. Now it's a restoration project instead of a writer, and it was the good pen.
Forty pens across three cases. If you had to list them tomorrow — for insurance, for a sale, for your own sanity — could you? With nib sizes and what you paid?
"I usually have a dozen inked pens in rotation, so it's hard for me to remember." — Paul-in-SF, Fountain Pen Network, "How do you keep track of ink in pens?"
"I get even less enjoyment when the disorganization gets to a point where it prevents me from actually using what I have." — The Gentleman Stationer, on why this actually matters
Where does the record live?
A modest collection is worth more than the laptop it's cataloged on. Every way collectors keep that record has the same flaw — it isn't really theirs, or it doesn't really happen.
Three entries, kept for you
Pen, ink, date — logged in seconds. The rotation view shows everything inked right now, so "what's in this one?" is never a mystery line on scrap paper again.
rotation view · fill history per pen · ink library
Nib size, grind, who ground it, material, filler, what you paid, what it's worth. The service history of your collection — the record a grail pen deserves.
nib grinds & tuning · values · photos
It knows what's been inked how long. The good pen gets flushed before it turns into a crime scene — not restored after.
time-inked tracking · cleaning history
Owners pin their real builds — nib grinds, materials, current inks — to a public board. Browse free, cheers the good ones, drop any build into your demo. Your grail could be pinned up there too.
Built like you'd want it built
It opens in your browser and runs entirely on your device. Your collection — with its values — never touches anyone's server.
Full CSV and JSON export any time. If you ever need to prove what you own, it's one click, not one weekend.
Your name greets you on the dashboard. It's your study, not a web service you're borrowing.
No renewal will ever ask you to keep access to your own pens. That's the whole philosophy.
