Everybody's dumb about something.
Tell us what you're clueless about and we'll write you a friendly beginner's book on the spot. The joke's on the topic — never on you.
From clueless to clued-in, in three steps
Step 1
Confess your dumbness
Type the thing you've been pretending to understand at parties.
Step 2
Duncan writes your book
Chapters, cheat sheets, and Top Tens — built for total beginners.
Step 3
Read it anywhere
In your browser, as an ebook, or as a printable PDF.
For the author who wants to go further
Pro mode
Your first book is a starting point, not the last word. Pro lets you shape your own book with a clean editor and Ask Duncan, while keeping its friendly Damn I'm Dumb voice.
Edit your book
Refine words, save private drafts, compare versions and publish when you're ready.
Ask Duncan
Ask for clearer explanations, useful examples or a fresh take on a selected passage.
Pictures and diagrams
Create or replace visuals with safe prompts and diagram types that fit your book.
Bring your research
Add up to 3 PDF, Word, Markdown or text files, 5 MB each, for Duncan to read into research notes.
Choose one-book Pro for a single project, or monthly Pro for your books across your account with credits refreshed each month. One AI credit balance covers Duncan edits, extra research, pictures and diagrams. Editing requires a desktop computer, and every published change must pass our safety checks.
