Zup support

Need help with captions, photo selection, sharing, or your privacy controls? Email support@samkarri.com.

What to include

Tell us what you were trying to do, what happened instead, your iPhone model, iOS version, and Zup app version. Do not email private photos, captions, passwords, API keys, or social account tokens.

Caption help

Generate defaults to OpenRouter’s Gemini 3.5 Flash vision model and requires an internet connection. TokenRouter’s OpenAI GPT-5.4 Image 2 model and Mistral are available alternatives, and selecting a provider alone does not upload anything. Zup asks for separate permission before sending selected photos to any provider. Apple’s on-device captioning remains part of the separately configured Daily suggestion flow on supported iPhones. You can review or turn off each hosted provider’s permission under Your Voice → Hosted intelligence.

Sharing help

Instagram Stories uses its native app handoff. X, Instagram professional accounts, Facebook Pages, LinkedIn, and TikTok use a connected account and show a final review in Zup before direct publishing. Facebook cannot publish directly to personal profiles, so Zup clearly separates Post directly to a Page from Share to a personal profile; the personal-profile choice opens Facebook’s native composer for the user’s confirmation. TikTok also offers Send as TikTok draft, which delivers the content to your TikTok inbox for you to finish, and Open TikTok instead as a Share Kit fallback. WhatsApp remains a native share handoff because its business API cannot publish personal Status updates or act as a user’s chat account. If a network asks you to connect again, reconnect under Your Voice → Connected posting so Zup can refresh the permissions required to publish. Apple’s share sheet remains available as the generic fallback for other compatible apps.

If a direct post fails, confirm that the account is connected, the caption and photo count fit the destination’s limits, and the network has not revoked Zup’s publishing access. Zup does not need your password; never send support a password or social token.
