How do I sync prompts across devices?

Turn on Google Drive sync in PromptShifu v3.1.0 to back up and restore your entire library as a JSON file you own. Sync is free, uses your own Google account via OAuth 2.0 with the least-privilege drive.file scope, and can be revoked at any time — your prompts are never stored on PromptShifu servers.

📘 Step-by-step setup: Read our complete guide: How to Sync AI Prompts Across Devices with Google Drive — screenshots, folder-permission checklist, and cross-device troubleshooting included.

Does PromptShifu work offline?

Yes. PromptShifu is local-first: prompts live in your browser's IndexedDB and search returns results in milliseconds with no cloud round-trip, so the entire library works offline. The only feature that needs a network is optional Google Drive sync, which connects only when you explicitly back up or restore.
