28 shippedThe set screen: four ways to read one set
Pick any set and rank every card in it four ways at once: the PSA 10 premium, the laggards, gem rate against price, and how far each card sits from its own peak. It answers the question people actually ask, which is not "what is this card worth" but "what in this set is cheap right now".
OpenAsk Cynthia about a whole set
Name a set in a question and Cynthia now builds the set screen before she answers, instead of asking you to name specific cards. She cites the ranked cards and links the screen she read.
OpenThe screener, rebuilt as a terminal
Four pills carry the filters people use every day and a disclosure holds the other ten, every figure now takes a ceiling as well as a floor, six named screens open with live counts, and the grid is never empty when you arrive. On a phone each row is a labelled quote card, so nothing scrolls sideways any more.
OpenThe binder scanner catches the top row
A nine-pocket page that came back as six now comes back as nine: a row of cards that sit slightly out of line is still a row, and an empty pocket in an otherwise even grid is told apart from a card the scanner missed.
OpenSingle card scans are a second or two quicker
The same scan, one to two seconds faster, and a little more accurate on the hard cases. Two lookalike pairs that used to swap places are now kept apart.
Open174 of 185 research notes recomputed from scratch
Every published figure in the archive was rebuilt from the data rather than trusted, and each of the eleven that could not be rebuilt is labelled with the reason. A number on this site should survive being checked.
OpenFifteen studies on the arguments collectors actually have
Vintage against modern, which sets hold up, which grading myths survive contact with the tape. Fifteen new pieces, each one independently recomputed before it was allowed to stay live.
OpenBinder scanning, rebuilt: a page in seconds, not minutes
Photograph a binder page and get every pocket named and priced. A page that took forty seconds to over two minutes now takes four to twelve, and a pocket the scanner is unsure about says so instead of guessing.
OpenThe landing page quotes like a terminal
Two live tapes run under the header: sets one way on top, the Pokemon Index and twenty two blue chip species the other way beneath, each with its artwork and its real move. The showcase below is a full quote panel with the recorded price series, the graded ladder and the grading maths.
OpenTwo scanning desks: single card, and binder
Scanning a single card is free. Binder and bulk scanning is its own tab for members, and on a desktop the scanner opens on a drop zone rather than a webcam square.
OpenAn intake desk for shops
Set your margin, floor and rounding, scan a stack, and every row comes back with an offer you can pass on, override by hand or annotate. Export a CSV or print the sheet, and a closed tab does not lose the session.
OpenEvery card page says what we actually recorded
Each page now opens with that card's own market price, its PSA 10 median and the number of sales behind it, as of the date we recorded them, rather than a stock promise. A new /about page explains in plain words what the platform measures and how.
OpenA set name resolves to the set you asked for
Typing a set name used to be able to land you on a different set that shared a word with it. The rule was rewritten and measured across all 777 set names in the catalog.
OpenThirty reference studies on how this market works
Grading economics, set lifecycles, liquidity, catalog structure, returns and risk, and sealed economics. Thirty pieces built on our own recorded tape, every one independently recomputed before publication.
OpenCynthia cites our own research
Ask her a question the archive already answers and she quotes the study and links it, instead of reasoning from scratch. Our recorded data is the only reason to ask her rather than a general chatbot.
OpenThree free days of Pro
Pro opened with a free trial: three days, a notice before the card is ever charged, and nothing taken if you cancel inside the window. The membership page always carries the terms in force today.
OpenA support desk and a public status page
Write to a person at /support and get a ticket you can follow. /status publishes seven components with ninety days of history, so you can see for yourself whether the thing you are waiting on is us.
OpenCynthia is a proper chat app on a phone
The transcript scrolls, the composer stays put, answers arrive at the top rather than showing you their tail, and you can read what you typed. Ask Cynthia now sits at the top of the home page.
OpenPrice targets, drawn on the card's own chart
Every card in the book carries a disclosed model target projected onto its price history. The direction is visible to everyone and the magnitude is a member figure.
Far more sets have a page of their own
Three quarters of the set catalog had nothing to land on when you searched for it. Those pages resolve now, and the search panel opens on screen on a phone rather than off the side of it.
OpenThe site speaks four languages
English, Spanish, Chinese and Thai, chosen from the menu beside the theme switch and remembered on your device. Research notes are machine translated with a badge saying so, and figures and card names never change.
Open a pack, and keep score
The pack simulator opens a real booster from any supported set using that set's researched pull rates and card order, prices every pull at the printing you actually got, and keeps a running paid against pulled ledger on your device. Entertainment and odds education, not cards you own.
OpenThe Grading Desk, every Tuesday
Nobody publishes PSA population history, so we snapshot it daily and the deltas are ours. Each week: which cards the registry is absorbing fastest, what is hardest to gem against its own era, and what a PSA 10 is worth over raw.
OpenA watchlist for the cards you are waiting on
Put a price on a card you are waiting for and the engine watches it for you every morning. A target disarms the moment it is crossed, so one move is one message and not a week of them.
Quant metrics on card, set and artist pages
Drawdown, volatility, momentum and the rest, computed only from series we recorded ourselves. If we have not recorded enough to say something, the page says nothing rather than filling the gap.
"Nobody has graded this card" is now an answer
Graded coverage now runs over the whole catalog rather than only the cards that happened to carry a price, and a card with no PSA sales on record says so in words instead of showing a dash. An absence we have checked is an answer; an absence we never looked at is not.
Pull rates on set pages
Where a published study exists, the set page shows what a pack actually yields, sourced verbatim. Where none exists, it says so instead of rolling a number.
OpenThe card screener
An empty grid you drive: filter roughly forty five thousand priced cards on price, PSA 10 median, population, gem rate and move, and every screen you build is a URL you can send to someone.

12 shippedDaily Buys
A conviction list published every day with buy, sell and hold ratings and a disclosed target on each. The engine has to clear its own costs before it calls anything a buy.
OpenOne hundred hand written card house views
A written view on a hundred individual cards, each one taken through an author, an insider read and an accuracy pass before it was published.
OpenMarket Reports for members
A dossier per card and per set: the recorded price series, the graded ladder, the grading maths and a written house view. Built for the cards and sets people ask about most, and refreshed on a rotation.
OpenA public track record
Every scored call is dated and kept, win or lose, at /reports/track-record. A research desk that only shows you its good weeks is not worth reading.
OpenA light theme
Warm paper by day, night sky by dark, chosen from the account menu or from the time of day the first time you arrive. Every page and chart was retuned for both.
Cynthia answers while she is still thinking
Answers stream in rather than landing all at once, with the first words in a couple of seconds instead of five to twelve.
OpenMoonstone Pro
Nine ninety nine a month: 300 Cynthia questions a day instead of the free desk's 25, binder scanning, and 200 API card scans a month. The free desks stay free, and every member figure we have built since is included.
OpenScan a whole binder page at once
Photograph a page of nine and get every pocket named and priced, instead of scanning card by card.
OpenCynthia, the research assistant
Ask a question in plain words and get an answer built from our own recorded prices, graded sales and population data, with the cards it names linked and the tables drawn. Send her a photo of a card and she reads it.
OpenImport your collection from a link
Paste a Collectr share link and the whole collection comes across, valued at our recorded prices rather than retyped card by card.
OpenThe Scan API
The same scanner behind a key, for shops and developers who want it inside their own tools. A free sandbox tier to try it on, and a dashboard showing exactly what you have used.
Openmoonstone opens
A card scanner, a research engine and a page for every card we track, on one site. Everything above is what happened after.
