Power Formulas Lifetime Deal

If you already hold an AI provider key and live in Google Sheets, yes, and the licence is unusually clean about what it covers. If you do not have a key, the price buys a tool you cannot yet run, and that is the first thing to settle.

What follows is a read of the sale page, the licence terms and the published rating record, checked on 14 September 2026. Nobody here ran the software.

Every tier describes usage as unlimited. That is accurate and it means the licence places no cap on you, not that the model calls cost nothing. The calls are billed by whoever you hold the key with: the listing names OpenAI and a later update adds Anthropic, Google AI and Cohere, so you choose the provider and the model, and you pay the provider directly for the tokens the formulas consume.

That arrangement is the better one for a licence meant to last. A tool with an included credit pool has to meter you eventually, and metering is how a permanent licence quietly turns back into a subscription. Here nobody has a reason to ration you, and a cheaper model next year is a setting rather than a renegotiation. The trade is that the bill never reaches zero, and a careless formula dragged down a thousand rows is a thousand API calls.

Scheduled hourly and daily refreshes are included on all three tiers, which is the feature that turns a sheet from something you recalculate into something that maintains itself.

One limit comes from Google rather than from the founder. The sale page's own summary of buyer complaints mentions exceeding property storage quota, which is an Apps Script limit and the kind of constraint that appears only once a sheet is large. Worth testing at realistic size inside the 60 day window rather than on a small sample.

Which tier to buy

One user, five users, or unlimited. Every tier carries the same formulas, the same API and SQL access, and the same uncapped usage, so there is no capability to grow into and no allowance to outrun. The only question is how many people need the add-on in their own Google account, which makes this one of the simplest tier decisions on the site.

Buy the single seat if you have a provider key, you work in Google Sheets, and you want model calls and API pulls as formulas rather than as a separate tool. Buy the team or unlimited tier only for seats, since nothing else changes.

Walk if you wanted AI generation included in the price. AahSheet Lifetime Deal is the closest comparison here, also spreadsheet-based and also bring your own key, with the important difference that it carries no refund window at all.

Power Formulas averages 4.89 across 19 ratings. Nineteen is too small a sample to generalise from, and the reviews run from 2023 to late 2025 rather than clustering in one week.

They are consistent about what the tool is for. Reviewers describe parsing scraped page text into structured columns, connecting APIs without writing code, and using the SQL access alongside the AI formulas. One from 2023 refers to paying $39 for the licence, so the price on this listing has risen since earlier rounds, which is ordinary and worth knowing if you are comparing against something you read elsewhere.

The founder replies to reviews, though the replies in the sample cluster in 2024, and the most recent product update on the listing is the addition of further model providers.
