Sustain
Different problems, different products: rolling subscription softcovers vs. AI-curated full albums.
Chatbooks built its reputation on simplicity. Its best-known product is the Monthbook subscription: you add photos from your camera roll, Google Photos, or a Chatbooks GroupChat, and with Autoship turned on, each book goes to print automatically once it has 30 pages. The pitch is: keep adding photos, and books keep arriving.
Sustain solves a different problem. It's for the moment when you want one specific album — a wedding, a year, a trip, a family yearbook — built from a real chunk of your photo library. The AI curates, designs, and captions; you fine-tune in the editor; you order a hardcover printed book or share it online.
These are not the same product. Chatbooks is great for rolling, low-effort books from photos you add as you go. Sustain is built for one finished, well-curated album that you actually care about.

Turn on Autoship and each Monthbook goes to print by itself as soon as it has 30 pages.
Add photos from your camera roll, Google Photos, or a Chatbooks GroupChat, a little at a time.
The softcover format keeps prices low for short, frequent books.
Branding, formats, and features are clearly aimed at parents documenting kids — and that audience is well-served.
Sustain scores photos for quality, removes duplicates, groups by face and scene, and picks the best shots. With Chatbooks, you choose the photos yourself.
Each Sustain page is designed by the AI for the photos it contains. Each section gets a chapter title and captions.
Sustain is for the wedding album, the year-in-review, the trip — not the rolling small softcover. Hardcover is the default.
You can tweak every photo, page, layout, caption, and theme.
•
You want a small softcover photo book to arrive automatically every month or quarter without doing anything.
•
You add photos as you go and want a book printed each time it fills up.
•
You're looking for short, simple, low-effort books rather than one curated album.
•
Cost-per-book matters more than design quality or curation.
•
You're documenting your kids' lives in rolling small format.
•
You're making one specific album — a wedding, a year, a trip, a family yearbook — and want it done right.
•
You have a large unsorted library and want the AI to pick the good photos and tell the story.
•
You want a book with AI-written chapter titles and captions.
•
You want to share an album online and order a printed book.
•
You want the interface in Hebrew, Spanish, Dutch, French, Italian, or German.
Chatbooks and Sustain solve different problems. If you want a small, automatic, recurring softcover book, Chatbooks is purpose-built for that. If you want one well-curated album with AI design and captions, that's what Sustain does.
