Every big photo book service now says “AI”. The word covers very different jobs: placing photos you have already chosen, suggesting captions, or choosing the photos for you from a library of thousands. This guide says which tool does which, based on each company’s own published descriptions, checked in November 2026.
We make Sustain, so read the Sustain section with that in mind. We have tried to describe the other services the way they describe themselves, and to say plainly where they are the better choice.
1. Choosing the photos. Going from 2,000 photos to the 150 worth printing: dropping duplicates, near-identical shots, blurry frames and screenshots, and keeping the strongest moment from each scene. For most people this is the slow part.
2. Laying out the pages. Placing the chosen photos into layouts across the book.
3. Writing the words. Suggesting captions, titles and chapter names.
A tool that only does job 2 still saves time, but you do job 1 yourself before you upload. That is the main thing to check.
Shutterfly’s photo book editor has AI-powered Auto-Fill. You upload your photos, choose whether to use all, most or your best photos, and Auto-Fill arranges them into layouts across the book, up to 111 pages. Magic Writer suggests captions.
Shutterfly’s own guides suggest preparing the photos first — removing duplicates, similar shots and blurry photos, and grouping them by event. So Auto-Fill does job 2 and helps with job 3, and leaves most of job 1 to you.
Shutterfly also has a free Designer Service: you upload photos and notes, and a person designs the book within 24 hours. And it sells cards, calendars and gifts in the same checkout.
Mixbook added Story Mode in June 2026. You upload your photos and describe the occasion. Mixbook says the AI then filters duplicates and near-identical shots, puts the strongest moments first, orders the photos into a story, and builds a designed first draft with suggested captions you can keep, edit or rewrite.
That covers all three jobs. Mixbook’s long-standing strength is design depth — templates, typography, papers and finishes — and you can change everything after the draft.
Chatbooks’ website and help center describe no AI feature. Its strength is a different kind of automation: in a Monthbook subscription you add photos from your camera roll, Google Photos or a Chatbooks GroupChat, and with Autoship each book goes to print as soon as it has 30 pages.
So you do the choosing, and Chatbooks makes sure a book actually gets printed, regularly. Books come in softcover or hardcover, and Classic Books go up to 366 pages.
Sustain starts with job 1. You upload a whole library — thousands of photos is the normal case — and the AI scores every photo, removes near-duplicates, groups photos by face and scene, and picks the strongest shots. Then it designs the pages and writes chapter titles and captions.
Everything stays editable. You can also leave notes on any photo, page or chapter, and the AI proposes fixes that you approve one by one. The interface works in English, Hebrew, Spanish, Dutch, French, Italian and German.
What Sustain does not do: it makes photo albums and books only — no cards or mugs — and it has no human design service.
