Sustain
Different problems, different products: rolling subscription softcovers vs. AI-curated full albums.
Chatbooks built its reputation on simplicity. Its core product is a subscription that automatically turns your phone's recent photos (from the camera roll, Instagram, or Facebook) into a small softcover photo book and ships it to you on a recurring schedule. The pitch is: stop thinking about it, just receive a book.
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, smaller softcover books. Sustain is built for one finished, well-curated album that you actually care about.

The Chatbooks subscription does the thing it promises: a book of your recent photos shows up at your door without you doing anything.
Direct Instagram and Facebook sync makes it easy to print social-style books with minimal work.
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. Chatbooks fills slots from a recent feed without that judgment.
Each Sustain page is designed by the AI for the photos it contains. Each section gets a chapter title and captions. Chatbooks uses a fixed template.
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.
•
Most of your photos live on Instagram or Facebook and you want a direct sync.
•
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 hardcover book with chapter titles, captions, and a real layout — not a simple grid.
•
You want to share an album online and order a printed book.
•
You want the interface in Hebrew, Spanish, or Dutch.
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.
