No psychology degree needed and no drama!

I once had a large team, and although I loved my helpers, they needed constant motivation. With Sintra, there’s no drama, just new ideas that I can simply accept or reject. It’s a huge relief—100% recommended.

Frequenly asked questions

What does a TikTok AI assistant do?

It writes hooks and captions, schedules posts, and reads back performance. In Sintra, Soshie plays this role. She drafts in chat and ships through the connected TikTok account.

Does she edit the video?

Soshie focuses on the words around the video. Video editing is outside her scope. Use your own editor and hand the video to her for the metadata.

What TikTok permissions does Soshie need?

Soshie asks for posting and metrics read scopes on the TikTok account you sign in with. Approve them on the TikTok authorization screen. Business and creator accounts have wider scope than personal.

Will she post Reels and Shorts too?

TikTok is one integration. Instagram Reels and YouTube Shorts have their own integrations under Soshie. Connect each you need.

What if Soshie's TikTok post fails?

Confirm TikTok is still connected and the account is in good standing. For posts rejected by TikTok content rules, the issue is on the platform side. Adjust the caption or media and queue again.
