Choose your AI
Updated for SystemSculpt 6.18 ·
SystemSculpt chat can use your own installed Claude Code or Codex on desktop, or hosted SystemSculpt AI on desktop and mobile. Select the backend in the run line below the chat message box.
| Choice | Where chat runs | Account and usage |
|---|---|---|
| SystemSculpt | Hosted service, available from desktop and mobile | SystemSculpt account access and available credits |
| Claude Code | Your installed desktop CLI | Your own Claude Code login and usage; no SystemSculpt plan needed for this chat |
| Codex | Your installed desktop CLI | Your own Codex login and usage; no SystemSculpt plan needed for this chat |
Claude Code
Install Claude Code and sign in on the same computer as Obsidian. Run claude and use /login when needed. Open SystemSculpt chat, select Claude Code, and use Detect again if you have just changed the installation or login.
Modes are Auto, Ask before edits, Accept edits, Plan only and Claude Code settings. Auto uses native safety checks. If Auto is unavailable, the plugin falls back to Accept edits and shows Auto unavailable; do not assume all edits will wait for approval. Claude Code settings inherits native configuration. SystemSculpt does not enable a bypass mode. Read the Claude Code guide.
Codex
Install Codex and sign in with codex login on the same computer. Choose Codex in chat, then Detect again if necessary. Read the Codex guide.
Modes are Auto, Ask, Read only and Codex settings. Auto uses a vault-root workspace-write sandbox with on-request approvals and Codex's automatic reviewer. Ask uses the user reviewer. Read only uses a read-only sandbox; Codex settings inherits native configuration. Review the action whenever the chat presents an approval request.
Hosted SystemSculpt AI
Sign in through Settings → SystemSculpt AI → Account, then choose SystemSculpt in chat. Hosted AI requires no separate provider-key setup in the plugin. The service manages its provider credentials and routing. See SystemSculpt AI for connection and credits.
Hosted modes are Auto, Ask and Full access. Auto asks before move/rename/trash, not every create or edit. Ask reviews every vault mutation. Full access permits mutations without asking.
What choosing a backend does not change
Using your own CLI for chat does not make semantic indexing, transcription, document processing or video generation local or free-native features; those use SystemSculpt's hosted services and credits. An on-computer CLI may send content to its AI service: “on this computer” does not mean offline inference. Studio's native execution uses native permissions rather than inheriting Chat's mode overrides.
Switching backend in an existing chat starts a new conversation while preserving the old one. Chat workspace explains draft/context transfer and read-only native chats on mobile.
