The short answer
Settings has no control that changes the email address on an account. Under Account it offers Subscription, Cancel, Reset password, Export Data and Import Chats. Under Preferences it offers Default model, Dark mode and Language, alongside the support and legal links. None of them edits the address you sign in with.
The only published route is to ask support, at [email protected] or through whizi.io/support. The privacy policy frames that as a correction request: depending on where you live you may have rights to access, correct, delete, or receive a copy of personal information, and Whizi may need to verify identity before completing the request. No procedure is documented and no turnaround time is published.
What you can and cannot change yourself:
| What | Self-serve | Where |
|---|---|---|
| Password | Yes | Reset password, in Settings, or the reset link on the login page |
| The email address on the account | No | No control for it in Settings. Ask support |
| Plan, or cancelling it | Yes | Settings, under Account |
| A copy of your data | Yes | Export Data, in Settings under Account |
| The whole account | Yes | Account deletion under Settings, with a two-step confirmation |
The Terms ask you to keep the address current anyway
Section 5 of the Terms of Service, on purchases and payment, puts an obligation on you that the product gives you no control for: "You further agree to promptly update account and payment information, including email address, payment method, and payment card expiration date, so that we can complete your transactions and contact you as needed."
A separate section, on user representations, adds that "If you provide any information that is untrue, inaccurate, not current, or incomplete, we have the right to suspend or terminate your account and refuse any and all current or future use of the Services (or any portion thereof)."
So an address you can no longer read is not a cosmetic problem to leave alone. Since there is no setting to fix it with, the practical move is to raise it with support while you still control the old inbox, because that inbox is what password recovery uses.
The error surface around signing in belongs to when you cannot sign in, including the password reset strings.
Making a second account does not move anything
The obvious workaround is to register again with the new address and carry your history across. A second account gets you none of your chats, none of your plan, and no second intro trial.
Chats cannot be moved between Whizi accounts. Export Data returns your account as one JSON file covering chats and messages, memory, projects and their file metadata, media, share links, subscription and referral profile. Import accepts exactly two sources: ChatGPT and Claude. A Whizi export is not a Whizi import format, so there is no supported path from one Whizi account into another. The export carries media as metadata plus a signed URL, and the bytes stay out of the file. Uploaded attachments and generated media are configured to expire after up to 30 days, so take your own copies of anything you want to keep.
The subscription does not follow the address. Billing is per individual account, and the tier is derived in exactly one place, from the subscription sitting on that account.
The intro trial is bound to the card, not the account. A second signup on the same payment method is refused with A $0.99 intro trial has already been used with this payment method., HTTP 403 with code duplicate_trial_payment_method. The rest of the checkout failure surface is on payment declined.
A new account starts on the free tier. The allowance is 7 messages, counted for the life of the account with no reset path. Free accounts are not model-gated inside that allowance, so the count is the only limit. What the message says when you reach it is on out of credits.
The new address has to be a permanent one. Disposable domains are refused at account creation, and the same refusal comes back from the checkout route when the signed-in account address is on the disposable list. Existing accounts are not blocked at sign-in, but a disposable address still blocks checkout. The string and both status codes are on when you cannot sign in.
On mobile, guest data links once. A guest token that resolves to a profile already claimed by a different account is refused, so device guest data cannot be re-linked into a second account after the first claim. The guest table on when you cannot sign in carries that string and its code.
One further limit, from the Terms: if an account has been terminated or suspended, "you are prohibited from registering and creating a new account under your name, a fake or borrowed name, or the name of any third party, even if you may be acting on behalf of the third party."
What to do instead, by situation
| Situation | The route that exists |
|---|---|
| You want a different password | Reset password in Settings, or the reset link on the login page |
| You are losing access to a work address | Export your data and raise the change with support while the old inbox still works |
| Your subscription is on the wrong account | Compare the address on the payment receipt against the one you are signed in with, then see subscription not active |
| You want to stop paying and start clean | Cancel first, confirm the cancellation, then decide about the account. See billing and cancellation |
| You want the account and its contents gone | Account deletion under Settings, with a two-step confirmation |
Cancelling and deleting are different actions, and neither of them changes an address. What each one covers is set out on billing and cancellation and what Whizi does with your data.
If you delete and register again, you are in the second-account case above: nothing carries over, because deletion is not a migration and no import path accepts a Whizi export.
- There is no setting in Whizi that changes your account email
- Nothing in Settings edits the sign-in address: not Subscription, Cancel, Reset password, Export Data, Import Chats, Default model, Dark mode or Language
- The only published route is support, at [email protected] or whizi.io/support
- The Terms still ask you to keep the address current
- Export Data first: it returns the account as one JSON file
- Import accepts only ChatGPT and Claude exports, so chats cannot move between Whizi accounts
- A subscription does not follow you, because billing is per individual account
- A new account starts on the free tier, with 7 messages for the life of the account
Frequently asked questions
What happens to my subscription and my chats while a support request is outstanding?
Nothing moves on its own. Account information and synchronized chat history are retained while the account remains active, so the chats stay where they are, and the subscription stays on the account that bought it, because the tier is derived from the subscription sitting there. Cancelling is a separate decision you can still make in the meantime, and it has no bearing on the address either way.
What should I do with the export file once I have downloaded it?
Keep it as your own copy. The export endpoint is the access counterpart to account deletion, and it works for guest sessions too, so a guest can take their chats and memory out before the device is gone. It is rate limited to 5 requests per minute, so take one clean copy instead of retrying. Quota counters, rate windows and push tokens are deliberately left out of it, so what you get is your content, not your bookkeeping.
I am losing access to the email I signed up with. What should I do first?
Export your data while you still can, then raise the change with support before the old inbox goes away. Password recovery runs by email, so once you cannot read that inbox you have lost the self-serve recovery route as well as the address itself.
Does changing my password change my email address?
No. They are separate. Reset password is available in Settings and from the login page, and it is the only credential you can change yourself. Its failure strings and every other sign-in error are collected on when you cannot sign in.
