PromGee Pricing — Lifetime License
Simple pricing for an AI English learning app focused on clear explanations and targeted practice.
Check out PromGee pricing for lifetime access to our AI English learning software for Windows. Pay once ($25 USD) for a single lifetime license key with no monthly subscriptions, hidden fees, or recurring charges.
PromGee uses one-time pricing. You pay $25 USD once, receive a lifetime license, and keep access to the full AI English learning app forever — no subscription, no hidden fees, no recurring charges. The price is the same everywhere and covers all current and future quiz categories.
The license is a single key you activate on one device at a time, and you are free to share it with family or friends. All learning data stays stored locally on your device, so nothing about your progress is ever sent to a PromGee server.
Why this pricing model is different
PromGee uses one-time pricing instead of recurring subscriptions. You pay once ($25 USD), keep lifetime access, and AI features are included via a generous free tier — no extra charges after purchase. An optional BYOK mode lets you bring your own API key if you prefer.
Everything included from day one
Every quiz category, AI explanation language, and future update is part of your single purchase. There are no paid tiers, no premium unlocks, and no feature paywalls.
A free AI tier that really is free
Quizzes and explanations run on a free AI tier with roughly 14,000 calls per day — far more than a single learner needs. You only pay again if you choose BYOK with your own API key.
Privacy is part of the price
There is no account, no email collection, and no analytics. Your practice history lives only on your Windows device, which is why a one-time license works for us.
Pricing questions
Is PromGee really a one-time payment?
Yes. You pay $25 USD once for a lifetime license. There is no subscription and no recurring charge of any kind.
What happens if I need to reinstall PromGee?
Your license key works across reinstalls and Windows updates. Since your data is stored locally, your progress stays on your machine.
Do AI features cost extra after purchase?
No. The built-in AI tier covers typical usage at no extra cost. An optional BYOK mode is available if you prefer to use your own API key.
