You Own The "Engine"... Now Get The
"Jet Fuel" To Scale Your Publishing Empire.
The Basic License gets you in the game. This Upgrade puts you on the Leaderboard.
Unlock the ability to write longer, faster, with total creative control and reach a global audience.
Let's be honest for a second: 5-chapter "pamphlets" and 500-word chapters are great for quick lead magnets, but they don't build fortunes. The Kindle Gold Rush has evolved.
To truly dominate profitable niches like Mystery, Sci-Fi, or Non-Fiction Authority, you need Volume, Depth, and Control. We are talking about 15 to 25 chapter books, deep 3,000-word chapters, and the power to translate your work into any language to capture the global market.
With your current Basic (FE) License, you are limited to:
- Max 5 Chapters per Book
- Max 500 Words per Chapter
- "Auto-Pilot" Generation Only (No editing control)
- English Language Only
Why limit your potential? It's time to automate the heavy lifting on an "Industrial Scale".

Do I need to pay for my own OpenAI / API Key?
Absolutely NOT! Stream Writer runs entirely on our powerful backend infrastructure using a simple Credit system. You don't need to mess with complicated API keys or unexpected developer bills. Just load your credits and let the app do the rest!
Will I lose my Standard/FE license if I say No?
Absolutely not. Your Standard license is safe and secure. This is simply an optional "Power-Up" for users who want to write longer, more complex books, control the AI step-by-step, and publish in multiple languages.
