Lead magnets people actually want to read
A good guide earns the email address and the trust that follows. Koobe turns your idea or your notes into a short, well-designed ebook you can gate, send or sell, without weeks of writing and design.

Good lead magnets take longer than the campaign they are for
The calendar has no room for a 20-page guide
Posts, emails and ads ship every week. The guide that would grow the list keeps slipping to next quarter.
Thin PDFs get downloaded, then ignored
A two-page checklist with a stock cover collects emails but rarely starts the conversation you wanted.
Design is a second project
Even with the words written, someone still has to lay it out, make a cover and export a clean PDF.
Built for marketers
Built from what you already have
Upload notes, a webinar outline or a few blog posts (PDF, DOCX, Markdown or text). Koobe writes from your material, so the guide carries your ideas and examples, not generic filler.
Designed, not just written
Each run gives you four cover designs with your title lettered in, plus type pairings and page layouts, so the PDF looks finished the day you write it.
Edit it until it sounds like you
Rewrite any part in plain words, rename and reorder chapters, and undo any change. Plus includes 3 seats, so a colleague can review the same draft.
Pick an idea, make it yours
Click one to put it in the box at the top, then change anything before you start.
Five steps to a finished book
- 1
Describe the book
One sentence, or pick an idea above. Add your notes if you have them.
- 2
Shape the outline
Rename, reorder or add chapters, then let Koobe write them in order. Close the tab if you like: it emails you when the book is ready.

Pick a cover and style
Choose from four covers lettered with your title and name, then the type and layout for your pages.

Preview and edit
Read every page and click any text to change it or cite a source. Or ask the assistant, and undo any change it makes.

Questions from marketers
Can I add my logo or brand colors?
No, there's no logo upload or brand kit. Your name or your company's appears on the cover as the author, and you choose from cover designs, type pairings and page layouts to get a look that fits your brand.
Does Koobe connect to my email platform or CRM?
No, there are no integrations. Download the PDF and upload it wherever you deliver lead magnets: your email platform, landing page builder or website.
How long should a lead magnet be?
Short usually works best. Pick one problem and solve it well. Koobe’s Short length is about 6 chapters and 7,000 words, and you can cut chapters from the outline before anything is written.
Will it read like generic AI content?
Not if you give it your material. Upload your notes, posts or outline so Koobe works from your ideas and examples, then edit every page before you download. You're responsible for what you publish.
