We are excited to share a major update: Lorebook is now available on Rochat Web, iOS, and Android. You can use it at rochat.ai, or update the app to get the latest experience.

If you have ever wanted a character to be more than a short profile, and to understand their background, relationships, taboos, locations, timeline, and special rules, Lorebook is built for that. It serves as a structured knowledge base behind your characters and scenes, helping your settings stay richer, more consistent, and easier to continue.

You can now find Lorebook in the Optional Settings for characters and scenes. Once a character or scene has unlocked the Gold Card, you can fully customize its Lorebook.

With Lorebook, you can:

• Complete background settings: Add family details, organizations, maps, abilities, events, relationship networks, and other deep settings.
• Bind it to characters and scenes: Lorebook is not limited to a single character. It can also help scenes keep consistent background rules.
• Bind up to 5 Lorebooks: Each character can be bound with up to 5 Lorebooks, keeping different layers of settings clear.
• Reuse across creations: Lorebooks you create can be reused across different characters and scenes, reducing repeated setup work.
• Activate on high-capability models: Lorebook can be activated on all SOTA series models, and is also supported on Rose, the model available to Rochat members.

To deliver a better Lorebook experience, we are also introducing Blackberry, our newest SOTA-level model. Lorebook asks the model to understand a large amount of background information, then call, combine, and perform it accurately during conversation. Blackberry is designed to better support this kind of complex creation, helping characters speak more naturally according to their settings, scenes follow rules more consistently, and stories continue with stronger continuity.

Lorebook is now officially live. You can use it to organize the background, relationships, rules, and key events for your characters and scenes. We will continue improving the experience based on user feedback.
