Sintra Soshie: Setup, Networks, Formats and Approval Rules

Soshie is Sintra's social media manager: she writes captions, designs images, plans a content calendar and posts to Facebook Pages, Instagram Business or Creator accounts, LinkedIn personal profiles and Organization pages, personal TikTok accounts and, where Sintra has switched it on, one YouTube channel. Nothing from her weekly automation goes live until you approve it. Drafts land every Sunday at midnight UTC, and an unapproved draft is simply never scheduled. She comes with the single Sintra X plan, alongside the other eleven AI employees, and draws on the same 250 credits a month: a post costs about 1 credit, 15 seconds of video about 40. Setup is mostly Meta account plumbing, a Brand Kit and well-named images. Reels are the gap to check first.

Which accounts Soshie can post to

Soshie publishes only to business-side accounts. On Meta that means a Facebook Page and an Instagram Business or Creator account; personal Facebook profiles and personal Instagram accounts cannot be connected ^[1]. The connection has three layers. You log in with a personal Facebook profile, because every Page hangs off one; the Page must be linked to a Meta Business profile; and the Instagram account must be linked to that Page. If a Page is missing from the dropdown, one of those links usually is too. Posting to Instagram alone works, but the Page still has to sit behind it.

LinkedIn comes as two separate integrations, Personal and Organization, and an Organization page may need a page admin to allow the Sintra app first. TikTok works with personal accounts only; business accounts are not supported yet. YouTube is in limited availability, offered to a small group of users before everyone, and the person connecting it must own the channel. In shared team workspaces, Facebook, Instagram and LinkedIn post only to project-oriented accounts, and only the workspace owner adds shared integrations.

The hard limit is one connection per integration per workspace: one Facebook Page, one Instagram account, one TikTok account, one YouTube channel. Running three Pages means three workspaces. Each one carries its own Brain AI, its own integrations and its own credit balance, so brand voice and images do not leak between them. A new workspace starts with 20 credits a month and no automations, so the weekly drafts need a paid plan there too; Sintra bills per workspace and does not publish what a second paid workspace costs. That separation is useful for brands that must stay apart, and tedious for anyone who wanted a single calendar across several Pages.

Before the first draft: Brand Kit, image names, themes

Soshie builds every generated post on your Brand Kit, which lives in Brain AI: logo, color palette, brand voice, value proposition, business description and a media library. Sintra's pricing page sketches onboarding as connecting tools in about five minutes and building the Brand Kit in about ten. Treat those as Sintra's estimates. The kit is shared with every helper in the workspace, and Soshie can pull Buddy, Penn or Dexter into the same chat, for example Buddy for campaign goals; the AI playbook covers how that hand-off works and where it stops.

Images need more care than most setups expect. Soshie finds an uploaded image by its exact title in Brain AI, so a camera's default file name is close to useless, while a descriptive title gets picked correctly. The automation uses each image only once. After a Social Media Manager post uses a photo, it is flagged and never pulled again for automated posts, though it stays in the library and you can reuse it in chat by title. Brain AI accepts JPG, PNG, GIF and WEBP images up to 20 MB per file, but not HEIC.

The last setting is the theme list. Soshie drafts each week from the themes you tick in the calendar settings, so a short, specific list gives steadier drafts than leaving everything on. Check your time zone too. Sintra detects it from the browser and falls back to UTC, and image generation does not remember the previous image, so a themed series needs the details of the image you liked restated in each request.

How the Sunday drafts reach your calendar

Every Sunday at midnight UTC the Social Media Manager automation drafts the coming week's posts and sends an inbox notice. Each draft sits in the Content Calendar under a Needs approval label. Open one and you can replace, regenerate or AI-edit the image, rewrite the caption, switch the page, move the date and choose between a feed post and a story. Then approve, decline, or publish at once. An unapproved draft is never scheduled ^[2], so a skipped Sunday means a quiet week.

The second route is chat. Ask Soshie for a post, upload or generate an image, point her at context in Brain AI, then publish immediately or schedule it. The one thing that runs without a check is a recurring scheduled task you set up yourself: it runs on its timetable, starts the day after you create it, keeps the time zone it was created in and asks nobody. On the phone there is no approval card yet, so you ask Soshie in chat to approve a waiting post; the Sintra mobile app guide lists what else stays web-only.

Comments and messages belong elsewhere. Facebook Page comment replies are drafted by Cassie, only for the first comment in a thread, and each batch must be approved or skipped before the next one arrives. Direct messages on Facebook, Instagram and LinkedIn get no automated replies at all; drafts are copied and pasted by hand. Soshie's job ends at the post.

Format limits, network by network

This grid rules out short-form video as a weekly habit on Meta. The automation does not publish Instagram Reels, Instagram video stories or Facebook Reels. Sintra's integration pages do list Instagram Reels as a separate integration under Soshie, and they say story and reel support depends on the Instagram API, so confirm with Sintra before you plan around Reels. Cross-posting has a quirk as well: a post can land on only one of Facebook or Instagram even with both connected. The fix is to ask Soshie to repeat the same image and caption for the other network.

TikTok and YouTube follow their own rules

Connected directly, TikTok publishes the moment the post goes out, with no scheduling unless the Social Media Manager handles it ^[3]. There are no drafts, no images or carousels, and no editing or deleting a video once it is up. Direct uploads take MP4 or MOV files from 3 seconds to 10 minutes and up to 4 GB, with 9:16 recommended, while the automation caps video at one minute. Helpers can also read views, likes, comments and shares for your 40 most recent videos.

YouTube asks more of you. You supply the video file, within Brain AI's 20 MB limit, plus a title, description and thumbnail; Soshie prepares the post and you approve it before it is scheduled. She cannot edit or delete published videos, change a thumbnail after upload, or touch comments and playlists, though helpers can read channel analytics. Posting there also binds you to YouTube's own Terms of Service, because Sintra uses the YouTube API Services.

What Soshie's work costs in credits

Soshie draws from the workspace's shared pool of 250 credits a month ^[4], which resets monthly with no rollover, even on quarterly or yearly billing . Sintra prices a post written, designed and published in chat at about 1 credit, and a post created on demand inside the Social Media Manager automation at 0. Scheduling or publishing costs nothing; chat images cost 0.5 to 1.8 credits each. Video is the expensive line, at about 40 credits per 15 seconds. When credits run out, helpers stop or are restricted until the next reset unless you upgrade. A recurring scheduled task costs credits on every run, and each teammate chatting with helpers pulls from the same balance.

Sintra's Summer Edition, in 2026, added short video ads with audio generated from a prompt, with a storyboard preview shown before a credit is spent. Use that preview. Complaints on Trustpilot and Google Play cluster around credits running out within days, charges for video that came out wrong, and, in one October 2026 Play review, video posts that failed without any notice. Sintra has replied that video is in early release and that it refunds credits for unsatisfactory results through help@sintra.ai. Sintra can change credit costs, with reasonable notice for significant changes, and the credit usage log shows what each action actually took.

Is Soshie enough to run your social calendar?

For a small business posting images, carousels and short text to a Facebook Page, an Instagram Business account and LinkedIn, yes, provided someone opens the calendar every week and approves the drafts. She is weaker as a short-form video engine. The weekly automation does not post Reels, video eats credits fast, and direct TikTok posts skip scheduling. Teams with several brands or a review chain should read Sintra for marketing teams first, because the owner is the only role and each brand needs its own workspace.
