PRO

PRO is not a gate on the product. The plugin, MCP, Cloud and pay-per-use generations all work without it. PRO is the economics for people who build a lot, plus the Rudiments library.

Price

Monthly $19 per month
Yearly $180 per year: $15 a month, saves $48 against twelve monthly payments
Founding $12 per month for the first 202 subscribers. The price stays locked for as long as you keep the subscription.

Subscribe at twozero.ai/pricing.

What PRO includes

  • $10 of Included Credits every month. How they spend and when they expire: Billing & Credits.
  • Every PRO rudiment in the Rudiments library, without buying them one at a time.
  • 10 GB of Cloud storage instead of 100 MB. See Cloud.
  • +5% bonus credits on every top-up, on top of the volume bonus.
  • Early access to new tools and builds.

Publishing rudiments

PRO members can apply to join the authors who publish on the Rudiments shelf: app.twozero.ai/creators. Publishing is by invitation for now. See Rudiments.

Cancelling

Cancel in your account settings at app.twozero.ai/settings: Manage subscription opens the billing portal, where you can cancel, resume, or change the card. No email to support, no waiting.

PRO stays active until the end of the period you already paid for. Purchased and Bonus Credits remain yours. Included Credits are forfeited the moment the subscription ends: they have no cash value and never roll over.

Switching between monthly and yearly is prorated for the rest of the current period, and unused Included Credits are forfeited at the switch. Leaving the founding plan ends the founding price permanently; it cannot be restored.

What happens to your files

Nothing is deleted when PRO ends. Your Cloud quota drops back to 100 MB, and if you are over it your Cloud becomes read-only: everything already there stays available and can be downloaded, but new uploads and new versions are blocked until you free up space.

ZERROR

ZERROR, the parameter controller by 404.zero, used to be sold on 404zero.com as a one-time purchase. It is no longer sold separately: it is a rudiment now and comes with PRO like the rest of the library. See Rudiments.
