01How to contact us
Use the contact form or e-mail contact@sumizai.com. To help us help you faster, include:
- the version of the app (select SumizAI in the Applications folder and press ⌘I) and of macOS;
- what you did, what you expected and what happened instead — a screenshot of the app window helps;
- for account questions, write from the e-mail address of your SumizAI account.
Never send us your AI provider key or your password. We will never ask for them.
02How do I connect an AI provider?
The app works with your own key. Create an API key in your provider's console (Anthropic, OpenAI, Google Gemini, Groq or OpenRouter), then in the app open Settings → Providers, choose the provider, paste the key and save. Before the first request the app shows what will be sent to the provider and asks for your consent. For a local Ollama no key is needed: install Ollama, start it and choose it in the app. You can also connect your own OpenAI-compatible server.
The key is stored in the macOS keychain on your Mac. Model usage is billed by the provider to your account with them, not by us. To stop sending data to a provider, disconnect it in the same place.
03Where are my AI notes?
On your Mac only. Each of your AI notes is a plain Markdown (.md) file in your notes folder; the
location is shown and can be changed under Settings → Notes folder. Nothing is stored
on our servers and there is no sync between computers, so please back up that folder (for example with
Time Machine). Because the files are plain Markdown, you can open them in any text editor.
Each file holds the title, the summary, the expanded answer and the original chat underneath, while
the vault's table of contents lives in base.md. Search and export (ZIP, PDF, PowerPoint) read
the same files. Nothing is hidden in a format only SumizAI understands.
04How do I cancel my subscription?
Apple manages the subscription. On your Mac open the App Store, click your name, then Account Settings → Subscriptions → Manage, choose SumizAI and cancel. Apple's guide: Cancel a subscription from Apple. Cancel at least 24 hours before the end of the current period (or the free trial) to avoid the next charge. Access continues until the end of the period you have paid for. Deleting the app or your SumizAI account does not cancel the subscription.
05How do I get a refund?
Payments go through Apple, so refunds are requested from Apple at reportaproblem.apple.com (Apple's guide). We cannot refund App Store purchases ourselves.
06How do I restore my purchase on a new Mac?
Install SumizAI from the Mac App Store with the same Apple ID, sign in to your SumizAI account and use Restore Purchases on the subscription screen. Your AI notes do not move with the subscription: copy your notes folder to the new Mac yourself.
07"This account is already used on 3 devices"
One account can be active on up to three computers. On a computer that is still signed in, open Settings → Devices and disconnect the one you no longer use, then sign in again on the new one. If you no longer have access to any of them, write to contact@sumizai.com from your account's e-mail address.
08I forgot my password
On the sign-in screen of the app choose Forgot your password? and enter the e-mail address of your account. We send a link to set a new password; it works once, for one hour, and setting the new password signs out all your devices. No e-mail? Check spam or write to contact@sumizai.com. Your AI notes are not affected: they stay on your Mac whether you are signed in or not.
09How do I delete my account?
In the app: Settings → Delete account, then confirm. This permanently deletes your
account, sessions and devices from our server. Your vaults and the .md files of your AI notes stay on your Mac.
Remember to cancel the App Store subscription separately (see above). Details: Privacy Policy — Deleting your account.
10System requirements
- A Mac with macOS 12 Monterey or later.
- An internet connection to sign in, to verify the subscription and to use a cloud AI provider. With a local Ollama, the AI itself works without sending anything off your Mac.
- An API key from a supported provider, or a local Ollama.
11Privacy and terms
