What you can do

In this release
New in 0.5.6
- Generate a character from an idea with your loaded local model, then review and edit the writing before saving.
- Export character definitions as V3 or V2 JSON, or as a portable PNG character card. Exported cards do not include your conversations.
- Murmur Sphere recommended models now open as a collapsible guide with descriptions, including Stheno v3.2 MPOA and Magnum v4 22B. Choosing a model opens its repository results.
- Slow CUDA prerequisite checks run in a visible, cancellable Training job. The final Training step gives a clearer handoff to the LoRA Library.
- Older-data carryover notices have both a close control and Don’t remind me again, so the same notice can stay dismissed after reopening the app.
Known limitations
Still an early alpha
- Windows may warn because the installer is not code-signed yet.
- Ollama and a compatible model are installed separately.
- Expect a few rough edges, and please tell me when you find one.
