How Soshie runs Instagram
She drafts your caption, lines up the hashtag set, and queues the post on the day you choose. Stories and replies get the same chat-first treatment.
Plug Instagram into Soshie
From your Sintra workspace, open Soshie and pick Instagram from her integration list. Sign in to the business or creator account you want her to post from.
Hand her the visual and the topic
Tell Soshie what the photo or reel is about. 'Three caption options for a behind-the-scenes shot of our team.' 'A launch caption with a soft CTA.' She writes in your voice and pulls product detail from Brain AI.
Approve, schedule, ship
Pick the caption you want. Soshie attaches the hashtag set, queues the post for your chosen time, and ships it through your Instagram account. Confirmation lands in chat.
