Is this non-fiction title generator free?
Yes. No sign-up, no limit, and everything runs in your browser.
Does it write the subtitle too?
No, and that is deliberate. Non-fiction subtitles need your specifics — the audience, the method and the result. The generator gives you the short half; write the subtitle to explain it in one clear line.
How long should a non-fiction title be?
The main title is usually one to five words. Anything longer competes with the subtitle and gets truncated in search results and retailer listings.
Can I use a title similar to a bestseller?
Legally, titles are generally not protected by copyright, but bestsellers often carry trademarks on their branding, and a near-copy will lose to the original in every search. Aim to sound like the category, not like one specific book.
