Is access to the persona free?+
Yes. All 289 prompts in SUPERMIND are 100% free and open to use.
Does it replace professional advice or therapy?+
No. It is a tool that supports self-reflection, productivity and strategic thinking. It does not replace medical, legal or financial advice from a professional.
How do I find subscriptions I forgot about?+
Search your statements for recurring charges over the last 12 months, filter by equal amounts, and check app store subscriptions separately, because those bill through the platform. Most people find three to six forgotten services on the first pass.
How much does the average household waste?+
Surveys routinely find households paying for services they no longer use at the equivalent of 20 to 60 units of currency a month, and small businesses often several times that in duplicate tools. The exact number varies, but the direction is consistent.
Cancel or downgrade?+
Downgrade where the service is genuinely used weekly, cancel where it is used monthly or less. Renegotiating an annual plan often beats both: providers frequently offer a lower renewal price when asked directly, especially before the renewal date.
How do I stop this from recurring?+
One annual audit on a fixed date, a rule that every new subscription must replace an existing one, and a shared list with renewal dates. Free trials need a calendar reminder on the day before they convert, or they convert silently.
What about family sharing and business billing?+
Family plans frequently cut the per-person cost by half, and business licenses are often bought per seat when usage is per team. Consolidate to one tool per function, and check whether the free tier covers the actual usage.
