Master Library Tools: PDF Rebrander, Cover Generator and Mockup Studio
Updated Nov 6, 2026
The Master Library includes three creation tools, all in the Create section of the app sidebar: the PDF Rebrander (put your brand on any product), the Cover Generator (four finished AI covers from a short description) and Mockup Studio (photoreal product shots with your exact cover). They're included in the $97 one-time plan, with no extra fees or credits.
PDF Rebrander
What it does: puts your logo, name and links on any product, hides the original branding, and downloads a ready-to-sell PDF.
- Place your logo anywhere on the cover and pages
- Add clickable buttons and links (your site, your offer, your booking page)
- Hide the original author
- Add or remove pages
- Save your brand colours so the other tools can use them too
Where: Create > PDF Rebrander (/tools/brand-products). Library products can open straight in the editor from the product page. Step-by-step guide: Using the PDF Rebrander tool.
Cover Generator
What it does: you describe your book and get four finished covers, title and all, in about 20 seconds.
- Four different concepts per batch
- Redesign any library cover, or match a cover you like
- Regenerate the ones you don't love
- Use a cover on your PDF in one click, or send it to Mockup Studio
Where: Create > Cover Generator (/tools/cover-generator).
Mockup Studio
What it does: turns your cover into photoreal product shots for your sales page, Etsy listing or Instagram.
- Your cover stays exactly as made
- Scenes like desk, hands, tablet and shelf, or describe your own
- Up to four scenes at once, and pick a brand backdrop
Where: Create > Mockup Studio (/tools/mockup-studio). More detail: Covers and mockups.
Fair use: the Cover Generator and Mockup Studio have a generous daily fair-use limit. If you ever reach it, the tool tells you, and it resets at midnight UTC.
AI Skill Pack (optional, for new members)
Master Library members can add the AI Skill Pack ($47 one-time). It's nine skills your own ChatGPT or Claude follows to rewrite a product as yours, write listings and sales copy, and plan a launch. It's the tool for writing product descriptions today. Find it under Create > AI Skills (/ai-skills) and read AI Skill Pack: what it is and how to set it up.
