Built for everything a collection needs.

Themed containers for anything you keep – one for your digital art, one for your baseball cards, one for the fair wishlist, organized however you think.

One horizontal scroll – a row of pieces in an order you chose, with a beginning and an end.

A single work: image, video, text, or quote – each with its own page, record, and note.

Every room draws on a single library – the same photograph can hang in two rooms making two different points, and neither is a copy.

Seven design schemes – from Modernist to Ink to Vibe – that reskin a room's type, color, and shape while staying HOP.

Titles, captions, and notes edit in place – no admin panel, no separate CMS.

Reorder pieces on a wall and walls in a room by dragging – the four-inch adjustment, without the ladder.

Record yourself walking someone through a piece – your voice, on the wall, where a wall label would be.

Arrow keys move piece to piece and wall to wall – they stop feeling like keys after about a day.

Everything dims except the work.

Nothing above the artwork – zoom holds, and you can step through the wall without leaving the piece.

Every piece has an address – send someone to the exact work, opened in context on its wall.

Loading gaps, layout shifts, and the small seams where attention leaks – hunted down deliberately, half-second by half-second.

Drag a folder of folders onto HOP and each subfolder hangs itself as a wall.

Paste an iCloud shared-album link and the album walks in, dates and cameras intact.

Ethereum, Tezos, and Solana wallets come in with their chain records intact – mints, transfers, the whole ledger biography.

After any batch upload, a single table for titling, dating, and describing everything at once – with copy-down and paste-from-spreadsheet.

HEIC from your iPhone, paste-from-clipboard, oversized scans – handled without asking you to convert anything.

Imports have no piece caps – jobs run with live progress, can be stopped, and resume where they left off.

Every piece gets an Accession number on arrival automatically, in a format you can customize or strip of our name entirely... along with a SHA-256 hash of the file itself.

Export any piece's record as a one-page certificate modeled on what a registrar keeps – with a QR code back to the work.

Where it came from, when, and through whom – free text or a structured chain, including on-chain history for NFTs.

Estimated value, acquisition price, source, and date – visible only to you unless you decide otherwise.

Condition notes, edition numbers, signatures, location – the registrar's fields, on your own holdings.

Show visitors the title, year, and medium; keep the price and the provenance to yourself – field by field, per piece.

Define the fields your collection actually needs, and decide per piece who sees them.

Any room becomes a printable catalog – cover, table of contents, one piece per page with its record.

Send a room to one person or publish it to everyone – what they see opens like a catalog, never a feed.

A room can require a password, or stay open for a week and then close – the way shows do.

A third tier past public and private, for the rooms you'd only walk someone through if you meant it – and when you let someone in, they're told they were let in.

Rooms, walls, pieces, artists, and collectors – full-text, across everything public and everything yours.

Follow the collectors you want to keep up with – publicly, privately, or into the Inner Circle when invited.

Save a room, a wall, or a single piece for later – private, no counts, with a note about why you kept it.

You decide whether your profile and each room appear in search at all – direct links keep working either way.

How many people came, at a glance.

Who visited, from where, for how long, which walls held them – first-party, never sold, never for advertising.

Your own visits don't inflate your numbers.
