Platform overview

These guides cover the main platform formats Bunzai supports. Each one gets its own page in this section, and every page has the same shape: what Bunzai reads from that platform, what a piece keeps on a same-app round trip, what drops when you convert it to a different app, how it looks on the Workbench, and a common-questions list at the end. Use the table below to find the page for your platform, then read that page for the full, honest story on your files.

The platforms

Platform	Handles	Page
Agnai	Characters, Lorebooks	agnai.md
Backyard	Characters	backyard.md
Chub	Characters, Lorebooks	chub.md
Lumiverse	Characters, Personas, Regex sets	lumiverse.md
Marinara	Personas, Regex sets	marinara.md
NovelAI	Lorebooks	novelai.md
Pygmalion	Characters	pygmalion.md
RisuAI	Characters, Lorebooks, Regex sets	risu.md
RoleCall	Characters, Lorebooks, Personas, Regex sets	rolecall.md
SillyTavern	Characters, Lorebooks, Personas, Regex sets	sillytavern.md

Handles lists the decks a platform's own files land on, Characters, Lorebooks, Personas, or Regex sets. An omitted kind is outside this table's coverage; it does not establish what the upstream platform can export. Check the generated format reference for current Bunzai adapters.

Two entries need a note. Backyard reads two different character shapes, the older flat JSON export and the modern .byaf archive, and both are covered on its one page. Marinara's own character cards are SillyTavern-shaped underneath, so they come and go through the SillyTavern page instead; Marinara's page covers only what is genuinely its own, regex scripts and personas.

If your platform isn't listed

Bunzai detects supported files by their contents. If your app exports Character Card v2 or v3 JSON, see the SillyTavern guide. Other exports may need a different adapter or may be unsupported; inspect the file before choosing a target.

For the exhaustive, generated list, every adapter Bunzai has today, run bun run bunzai formats, or read the format reference, the technical version of this page. It is built straight from the live adapter registry, so it never drifts from what the app can actually do.

Common questions

• Why do some platforms list fewer kinds? This table describes the adapters covered by these guides. It is not a complete inventory of upstream features.
• Will I lose anything moving between two platforms? Sometimes, and it is always spelled out. Each platform page has its own "what changes when you convert" table with the exact fields that stay and the ones that drop. The converting guide covers the general rule.
• My app isn't listed. Now what? Inspect the file or try importing it. Bunzai recognizes supported file shapes rather than relying on the app's name, and reports files it cannot read.
