kneepotato — How It Works

Enter your name and birthdate, and the app combines one body part and one food into your "official stage name." The name "kneepotato" is itself a product of this same combination — knee plus potato.

The one-line version

This isn't a game — it's an issuing office. It isn't a random draw either: the result is a deterministic hash of your name and birthdate, so the same person entering the same details always gets the same stage name.

How it works

You type your name and pick a birthdate. Those two values get hashed to select one entry from a list of 59 body parts and one from a list of 176 foods — 59 × 176 = 10,384 possible combinations. Stitch the two together ("Knee" + "Potato" → "Kneepotato") and that's your official stage name. You never choose the body part or the food directly — only your name and birthdate decide the outcome.

How the name gets made

The result screen looks like an official certificate stamped "ISSUED," with a case number and a field table for body part, food, texture, and issue date, under the line "This is your official name. Forever." That case number is a decorative stamp derived by hashing your combination — it is not the same as a real, server-issued unique registration number. Getting an actual unique registration requires applying separately through the Trademark Office feature, capped at 5 registrations per identity. Submitting the form triggers a short, faux "installation" animation before the reveal — that's pure atmosphere; the actual result is already computed before the animation even starts.

Clicking "Try Again" doesn't let you collect combinations endlessly. It only replaces the one official stage name you currently hold with a new result, and re-submitting the same name and birthdate produces the identical combination every time. To see a different one, you have to change the name spelling or the birthdate itself.

How to use it

1. If you don't like the result, change the input, not just "Try Again"

Clicking Try Again with the same name and birthdate just gives you back the same combination. If you want a different stage name, vary how you spell your name (spacing, a nickname) or nudge the birthdate — the fact that the output is deterministic is exactly the lever you have to pull.

2. Use the Trademark Office if you actually need a unique registration

The case number on the basic certificate is cosmetic, so two different people entering the same name could land on the same combination and both see "their" number. If you want this stage name uniquely tied to you on the server, register it through the Trademark Office — capped at 5 registrations per identity.

3. "Save Card" and "Share Link" serve different purposes

"Save Card" renders your certificate as an image, ideal for posting to social feeds. "Share Link" copies a URL that reproduces your exact result on a read-only page — use it when you want a friend to see your specific certificate, not just a description of it, with one click.

4. Back up your Product Key

With no login, an on-device "Product Key" is your only identity. Lose it and everything you've collected is unrecoverable — export a backup string from the settings screen ahead of time, before you need it.

5. Check "My Documents" for names collected through other routes

The base generator isn't the only way to acquire a stage name — there's a once-a-day ration, a way to fuse names with a friend's, a guessing/betting mode, and more. "My Documents" is the collection screen that gathers everything you've picked up across all of them, so it's worth a look beyond the initial issuance.

FAQ

Do I need an account?

No sign-in is required. Instead, an anonymous "Product Key" generated on your device acts as your identity. The server never sees the raw key, only a hash of it.

Where is my data stored?

By default, only in your device's browser — never sent to a server. A handful of features (trademark registration, discarding to the recycle bin, appointing a friend) do send a minimal amount of data to a server.

Does the same name and birthdate always give the same result?

Yes. The body part and food aren't picked randomly — they're derived by hashing your name and birthdate, so identical input always produces the identical combination.

Can I click "Try Again" to collect multiple combinations?

No. Try Again replaces your one official stage name with a new result — it doesn't add to a collection — and clicking it again with the same name and birthdate gives you the exact same result. To see a different combination, you need to change the input itself.

Is the result a real registered trademark?

The case-number stamp on the basic certificate screen is decorative. If you want a genuine, server-issued unique registration number, you have to apply for it separately through the Trademark Office feature, which caps each identity at 5 registrations.

What happens if I lose my Product Key?

It cannot be recovered. Without a backup string you exported ahead of time, everything you've collected is gone for good.
