Is AI translation good enough to go global?

It's getting there fast, but "good enough" depends entirely on what you're publishing and how much you're willing to invest in quality control.

The reality: AI translation from tools like DeepL, Google Translate, and the translation features built into KDP and Draft2Digital can produce a readable draft in Spanish, German, French, Portuguese, or Italian from an English source in minutes. For non-fiction -- especially practical, instructional content -- the output is genuinely usable with moderate human editing.

For fiction, it's shakier. AI handles plot and dialogue reasonably well, but it murders idioms, flattens humor, and strips away the stylistic nuance that makes literary prose work. If your novel relies on voice and wordplay, a raw AI translation will sound like it was written by a competent robot -- technically correct but soulless. Characters who speak with distinctive voices in English will all sound the same in a raw AI translation. Jokes will land flat. Cultural references will either be translated literally (which makes no sense) or dropped entirely.

That said, even for fiction, AI translation as a first draft can save you enormous amounts of money. The key is that the human editor doing the "Soul-Check" needs to be experienced with literary translation, not just bilingual. There's a difference between someone who speaks Spanish and someone who can make your thriller feel like it was written in Spanish.

The cost-effective approach:

Use AI translation to generate your first draft. This takes what used to be a $5,000-10,000 professional translation job and turns it into a $500-1,500 "translation plus native edit" job. Hire a native speaker of the target language -- not necessarily a professional translator, but someone literate and ideally familiar with your genre -- to do what I call a "Soul-Check." They read through the AI translation and fix the things that sound wrong to a native ear: awkward phrasing, cultural references that don't land, idioms that were translated literally.

Which languages to start with:

German and Spanish are the two highest-ROI translation markets for English-language indie authors. Germany has a massive ebook market and relatively low competition from indie authors. Spain and Latin America combined represent an enormous Spanish-reading audience. French and Portuguese (especially Brazilian Portuguese) are the next tier. Italian has a smaller but dedicated reader base.

The metadata trap:

When you publish a translated book, you need a new ISBN, a translated title, a translated description, and translated keywords. Don't just machine-translate your Amazon description -- that's the first thing a potential reader sees, and if it reads like Google Translate output, they won't buy the book. Have your native editor write (or at least polish) the product description in the target language.

Also: Amazon has separate marketplaces for different countries (amazon.de for Germany, amazon.es for Spain, amazon.fr for France, etc.). Your translations should be uploaded directly to the relevant marketplace through KDP, targeting the local audience. Draft2Digital can also handle international distribution through their partnerships with local retailers like Kobo, Apple, and Tolino (which is massive in Germany).

My advice: If you've got a non-fiction title that's selling well in English, translate it into German and Spanish first. Use AI for the draft, hire native editors for the polish, and publish through KDP and Draft2Digital to cover both Amazon and the local retailer platforms. If the translations sell, expand to more languages. If they don't, you've invested $500-1,000 to find out, not $10,000. That's a small bet with enormous upside potential -- the kind of calculated risk that separates real publishers from hobbyists.
