ST card editor on macOS: built-in Silly Tavern, web tools, and file-first apps
On a Mac, you might run Silly Tavern and only touch .png character cards`—here is a clean split of editor options. Install paths: Silly Tavern on macOS; backup → edit → re-import: macOS Silly Tavern card edit workflow.
Not an endorsement of any third-party service. Web tools may upload files—read their terms.
1) Built-in Silly Tavern editor
Best for quick edits while iterating in chat. You already have the server running on macOS; use the Characters UI to change fields and export when needed. Tradeoff: less convenient for batch work or diffing many cards—see the card editor series.
2) Web-based card editors (browser on macOS)
Best for one-off edits without opening ST’s UI. Privacy: uploading a PNG may upload embedded JSON to a remote server unless the tool is explicitly local/offline.
3) Standalone / cross-platform editors
Best for power users who want offline edits, validation, or batch operations. You still manage where files land on disk under your characters/ folder (paths vary—Silly Tavern on macOS).
4) File-first macOS workflows (PNG + embedded JSON)
Some users prefer Finder + a Mac app that reads/writes the JSON inside the PNG, keeping everything on disk under their control. That matches macos st card edit intent: treat cards like assets, not only form fields.
Compatibility reminder
Editors differ on V2 vs V3 and optional fields—(4/5) V2/V3 compatibility.
