How PDFIdeas works
AI finds the gap, writes the guide, and pre-fills your Gumroad listing. You review, publish, and collect the sales.
Pick a niche
Choose from 20 proven niches — Parenting, Finance, Fitness, Productivity and more. Or type in your own topic idea.
We surface niches with real search demand and manageable competition — sweet spots where a $9–$27 guide sells without a big audience.
Generate ideas with AI
Hit Generate and get up to 20 scored ideas in seconds. Each idea includes title, audience, pain point, chapters, suggested price, and an opportunity score.
Opportunity score 0–100 weighs search volume, competition level, and trend direction. Focus on 70+ scores first.
Write the full guide
Click "Write Guide" on any idea. AI writes a complete, structured guide — introduction, all chapters, conclusion, and a Gumroad-ready description.
Typical guide: 1,500–3,000 words, 5–8 chapters, ready to paste into Canva or Google Docs. Takes about 30 seconds.
List and sell
Hit "Gumroad" to open a pre-filled product listing. Set your price ($9–$27), upload the guide as PDF, and you're live.
Gumroad charges 10% + payment fees. No monthly subscription. You keep 85–90% of every sale.
Common questions
Do I need to be an expert to write these guides?
No. The AI does the research and writing. Your job is to pick a good niche and add your personal framing. Buyers want concise, actionable guides — not academic papers.
How long does it take from idea to published?
Idea → written guide → Gumroad listing takes about 10 minutes. Building a library of 10–20 guides takes a weekend.
What makes a guide sell vs. sit unsold?
Specificity wins. "The First 30 Days With a New Puppy" outsells "Dog Care Guide" every time. Our opportunity scores and audience fields help you get specific.
Can I sell the same guide on Etsy too?
Yes. Export the text, design a cover in Canva, export as PDF, and list on Etsy Digital Downloads. Many creators list on both platforms.
Is PDFIdeas free?
Yes — generating ideas and writing guides is free. No account required. We make money if you love the tool and tell others about it.
