What this
is.
Reaction Press turns one line of text into a reaction character — a cut-out on a flat green screen, numbered out of ten thousand, signed so anyone can check it. Not a subscription, not a stock library, not a chat window.
The short version
You type what the character is doing. The site compiles that into a production prompt, renders it, keys it, and gives you a numbered edition with a certificate. One piece costs US$1.99. Ten thousand will ever exist.
The thing being sold is not the picture — anyone can generate a cartoon. It is the number: a fixed run, issued once, bound to the exact bytes of the file by a signature that keeps working if this site disappears.
What you get
- A 1024 × 1024 PNG of the character on a uniform chroma-green background, ready to key out.
- A number from 1 to 10,000 that will not be issued twice.
- A signed certificate in JSON — number, file fingerprint, seal time, holder.
- A public key at
/.well-known/reaction-press.pubso the certificate can be checked offline.
How it works
- Type one line. What the character is doing, and optionally a prop.
- The prompt is compiled. The line is wrapped with the constraints that matter for a usable cut-out — flat key colour, no cast shadow, generous margin, no text.
- It is rendered and keyed. A near-duplicate check runs before the piece is accepted; a blank render is refused rather than sold.
- You pay, and it seals. The piece on screen is bound to you, the certificate is signed, and the file unlocks.
Who it is for
People who need a reaction image that is not the same ten frames everyone else uses: video editors and streamers who want a clean overlay subject, designers who need a cut-out character, and anyone who would rather link to a numbered certificate than a screenshot.
Questions
What is Reaction Press?
An online press that issues numbered reaction characters as chroma-key cut-out images, each with a certificate anyone can verify without an account.
How much does a piece cost?
US$1.99, once. No subscription. You pay, the piece on screen is sealed to you, and the full-resolution file unlocks.
What do I actually receive?
A 1024 × 1024 PNG on a flat green background, plus a signed certificate of edition naming its number, its file fingerprint and when it was sealed.
How is this different from asking an image generator?
A generator gives you a picture. This gives you a picture that is numbered inside a fixed run of ten thousand, cannot be issued twice, and carries a signature bound to its bytes. You are buying the number and the proof.
How does verification work?
Certificates are signed with Ed25519 over a canonical payload. The payload and signature travel inside the certificate file, and the public key is published, so a third party can check a piece offline without trusting this site. There is a verification page that does it in the browser.
How many pieces will exist?
Ten thousand. When the last number is issued, the press run is over.
Can I use the image commercially?
Yes. You hold the file and the certificate, and you may use the image in your own work. A piece can also be transferred to someone else, which is recorded in the certificate's custody chain.
What format are the files in?
PNG, 1024 × 1024, on a flat chroma-green background. The preview on the site shows the character already keyed; the file you download is the plain green plate.
