Upgrade 6 of 6 · The last offer, and the only monthly one. It is about what to write next.
You can write a book a day now. Which book?
Autopilot and Agency removed the limit on how much you can produce. They did not tell you what to produce.
Fiction shelves move every week. A sub-niche that was empty in spring is crowded by summer, and a German or Brazilian shelf can be wide open while the English one is full.
Guessing wrong once costs a weekend. Guessing wrong at Autopilot scale costs months of output.
ShelfRadar
ShelfRadar is a separate app that watches thriller, mystery and kids' horror shelves across Amazon marketplaces every day, scores demand against competition, and turns the gaps into weekly "write this next" briefs. One click sends a brief into ShadowPress as a new book, or straight into your Autopilot queue.
✓ Daily-updated demand and competition scores for thriller, mystery and kids' horror sub-categories
✓ Every Amazon marketplace that matches your Global Shelves languages, side by side
✓ Weekly "write this next" briefs: niche, reader age, hook pattern and price band
✓ One click sends a brief into ShadowPress as a new book or an Autopilot queue
✓ Rank and review tracking for your own published books
What it does not do
- It estimates demand from public ranking data. Estimates are not sales guarantees, and no tool can promise a book will sell.
- It covers fiction only: thriller, mystery and kids' horror. It is not a low-content or non-fiction research tool.
- Briefs in other languages can only be sent to ShadowPress if you own Global Shelves; queueing needs Autopilot.
- It is a monthly subscription. Cancel any time in WarriorPlus; access ends when the paid month runs out.
Skip it if you already know exactly what you will write for the next few months. Every one-time product you own keeps working without it.

Questions
Why monthly when everything else was one-time?
Because the data is. ShelfRadar pays every month for fresh ranking data and refreshes it daily. A one-time price would mean stale data or a service that shuts down.
Is it part of ShadowPress?
It is a separate app with its own screens. You open it from the ShadowPress sidebar with the same login, no second password.
What happens if I cancel?
Nothing in ShadowPress changes. You keep every book and upgrade you bought. Only ShelfRadar access stops at the end of the month you paid for.
