The main line is access to AI subscriptions you cannot sign up for yourself. Prices are below; full specifications are in the catalogue.
AI subscriptions
Activating an official subscription on your own account. Not an account resale — no account is supplied.
ChatGPT Plus¥179/mo
We need your ChatGPT session credential (step-by-step guide after checkout). It is used once to place the top-up request, never stored; you can revoke it right after by logging out of all devices.
Claude Pro¥189/mo
Same, on Anthropic’s side.
Codex invite
Send one invite from your own account; the rest runs unattended. Credit lands on your account.
Codex invitemetered
Usually about fifteen minutes. A failed run does not consume a use.
Verification numbers
A single-use overseas number for receiving one signup code.
One code¥1.90
700+ platforms · 100+ countries · no code in 20 minutes returns the charge to your card balance
Temporary mailbox
Open and use. No signup.
Temporary mailboxfree
Expires after three days. Readable only by whoever created it.
The subscription is activated inside the account you already own, rather than handing you someone else’s. What each item needs from you is in the specification on the cards above.
Yours once it is on
Renewal, cancellation and rebinding stay with you. None of it routes back through us.
A setup service, not a resale
We do not register accounts for you and we do not supply ready-made ones. What you buy is having it done.
How ordering works right now
Payment channels are still being set up, so orders are arranged by email for now: hello@jichuanai.com. This section will be updated once the channel is live. Replies within 1 business day.
If you have already ordered, use order lookup. Refund rules are in the refund policy, written to the level of detail you can act on.
Invoices, for everything on the site
Every item here can be invoiced, with no exceptions — subscription setup, Codex invites, verification numbers, website builds and GEO work alike.
The operating entity is a registered individually-owned business (个体工商户). Send the billing details to hello@jichuanai.com. Replies within 1 business day.
The limits, before you pay
This is an independent third-party service, not affiliated with or authorised by OpenAI or Anthropic.
The user terms of both OpenAI and Anthropic state that account credentials must not be shared and that others must not be allowed to use your account. Setup requires your account email, and responsibility for that step sits with the account holder.
This sits on the homepage rather than in the footer because you are entitled to read it before you pay.
We also build sites and do GEO
A branch of the business, not the main line. It is here because it ships real work, not as an afterthought.
Website builds
Static, bilingual, design through to deployment. GEO baseline included at every tier.
