Word packs are one-time purchases, not a subscription. You pick 10k / 50k / 200k words, pay once via Stripe Checkout, and the words are credited to your account (or to the email you used if you were signed out).
We count max(words in, words out) per cleanup. Signed-in
users can spend pack balance from the homepage; agents can spend the
same balance with a usk_… API key from Settings.
x402 is a pay-per-request path for agents. Instead of
buying a pack up front, a client pays a small amount of USDC on Base
for each call to POST /v1/unslop/x402 (currently about
$0.02 per request, up to the max word limit).
Humans usually buy a Stripe pack. Agents that already speak x402 can pay as they go without creating an account.
No. Use whichever fits:
Maybe. Tools like Pangram and similar “AI detectors” produce a lot of false positives. Cleaning awkward AI phrasing does not guarantee a “human” score, and we do not optimize for beating detectors.
Use unslopifymy to make copy clearer and less template-sounding—not as a bypass for academic or compliance detectors.
