# Sintra AI Employees: How Helpers, Brain AI and Credits Work

> How Sintra's 12 AI employees share Brain AI, what waits for approval, what scheduled tasks do alone, what each action costs in credits, and where it fails.

Sintra's AI employees are 12 role-based assistants, from Soshie on social media to Dexter on data, that share one knowledge base, Brain AI, inside a workspace. They draft posts, emails, replies, plans and reports in your brand voice. **They do not act on their own by default**: posts and customer replies wait for your approval, and only scheduled tasks you create run without a check. Everything draws on one pool of 250 credits a month on the single Sintra X plan, reset monthly with no rollover. Our read: a capable drafting team for a small business, not unattended staff.

Under the hood, Sintra says the helpers run on GPT and Claude models for text and on Imagen and gpt-image for visuals. In our reading, each built-in employee is a role with its own focus, working from those models and from whatever you store in Brain AI. That framing sets expectations. A helper is only as informed as your workspace, only as connected as the integrations you approve, and only as reliable as the model behind it on a given day.


**250** — Credits a month per paid Sintra X workspace, reset monthly with no rollover



- **12 roles** — Built-in AI employees, all on one plan
- **20 MB** — Per-file limit for Brain AI uploads
- **Every 10 min** — Most frequent schedule for a task that runs without approval


## Twelve specialists who mostly work one chat at a time

The roster is Soshie (social media), Penn (copywriting), Seomi (SEO), Emmie (email marketing), Cassie (customer support), Milli (sales), Vizzy (virtual assistant), Buddy (strategy), Dexter (data), Commet (websites), Scouty (recruiting) and Gigi (personal growth). All twelve come with Sintra X. Each helper works in its own chat thread and keeps working in the background, and search on the home screen routes a task to the most qualified helper. Parallel chats exist only on workspace-based billing plans and are not yet on mobile.

Helpers can hand work to each other inside one chat. Sintra names chains such as Commet drawing on Penn and Seomi, or Milli passing follow-ups to Emmie and Cassie. The limits are tight, though. Only the helper you are chatting with can use integrations, the main helper cannot delegate, the inter-helper conversation is not saved in Chat History, and Sintra calls the feature still in development [1]. In practice, open the chat with the helper that owns the integration you need.

Beyond the built-in twelve, Helper Builder lets accounts on workspace-based billing create custom AI employees that use Brain AI, run automations and take assigned tasks; building one costs about 5 to 10 credits. Sintra's Summer Edition, in 2026, added a Marketplace of 50+ community-built employees. They install free, but every use draws on your credits, Sintra can remove one at any time, and their output still needs review. Built-in helpers can only be hidden. Custom ones can be deleted.

## Brain AI is the memory, and it knows only what you save

Brain AI is the shared knowledge hub, one per workspace and never shared across workspaces. It holds snippets, links, files, images, videos, a lightweight CRM of databases and the Brand Kit: logo, colors, brand voice, value proposition, business description and media library. Onboarding asks guided questions to seed it, and the mobile app offers 10 daily training questions. Every helper reads from it, which is why a Soshie post and an Emmie email can share one voice without a fresh brief each time.

The upload rules are specific. Files can be up to 20 MB each. Text formats are TXT, PDF, DOCX, ODT, MD, JSON, HTML and XML with copyable text, so scanned PDFs are unreadable; images are JPG, PNG, GIF and WEBP; videos MP4, AVI, WEBM and MOV; spreadsheets CSV, XLSX and XLS. TIFF, HEIC and audio are out. **Connected apps do not feed Brain AI automatically**, and nothing syncs live from Google Drive or Notion. Only what sits in All Knowledge is used consistently.

Two habits prevent most surprises. When you ask a helper to save something, Brain AI stores a summarized snippet rather than your exact words, so brand guidelines and legal text belong in a manual save. Deleting knowledge is final, with no confirmation and no undo. Folders, auto-organization and the contradiction check are limited to workspace-based billing plans and are not on mobile yet, and only the workspace owner can delete snippets and files.


> 💡 **Save brand rules by hand:** A helper saving to Brain AI keeps only a summarized snippet. Paste brand guidelines and legal wording into All Knowledge yourself so the exact text survives.


## What runs without you, and what sits in an approval queue

Sintra lists five automations: Social Media Manager (Soshie), Inbox Manager and Facebook Commenter (Cassie), and Daily Summarizer and Meeting Notetaker (Vizzy, the second an early beta for a limited number of users). Among the built-in twelve, only Soshie, Cassie and Vizzy have automations, though custom employees can run them too. Otherwise a helper acts only when you ask in chat, through a scheduled task, or through an automation. The Summer Edition gathered tasks and automations into a single Automations home.

Most output queues for you. Social Media Manager posts always need approval or they are never scheduled, and the drafts arrive weekly, Sunday at midnight UTC. Inbox Manager sorts mail into 8 fixed categories and leaves reply drafts in your drafts folder for three of them (To Respond, Cold Email, Awaiting Reply); Facebook Commenter replies are approved batch by batch. Chat emails go out only when you press Send, calendar events open a confirmation window, and financial writes such as QuickBooks invoices wait for you. Cassie is not a chatbot. The details live in [how Soshie posts](/articles/sintra-soshie) and [what Cassie drafts](/articles/sintra-cassie).

The exception is the recurring scheduled task. You write a prompt and a timetable (once, daily, weekdays, weekly or monthly, as often as every 10 minutes), and it runs with **no approval step: a task set to send an email sends it** [2]. A new task starts the day after you create it, keeps the timezone it was created in, uses credits on every run and fails if its integration is not connected. Sintra's Terms treat any action an AI assistant starts as authorized by you.


> ⚠ **Scheduled tasks skip approval:** A recurring task set to send an email sends it, with no review step, and Sintra's Terms treat what it does as authorized by you.


## How 250 credits a month get spent

Sintra X includes 250 credits a month per workspace. They reset on the day of the month your subscription started, even on quarterly and yearly billing, with no rollover, and they cannot move between workspaces. Sintra bills per workspace: an extra workspace starts with 20 free credits a month and no automations. Sintra says costs are approximate and the same across all helpers [3]. Some actions are free: setting up automations, scheduling or publishing a social post, and adding files to Brain AI yourself use no credits.

| Action | Approximate credits |
|---|---|
| Chat message (longer threads cost more) | 0.1 to 1 |
| AI reply | about 0.1 |
| Social post written, designed and posted in chat | about 1 |
| Image in chat | 0.5 to 1.8 |
| Website scrape | 0.5 |
| Scheduled task, each run | 1-5 basic, 3-10 research, 5-20+ complex |
| Building a custom AI employee | 5 to 10 |
| Video | about 40 per 15 seconds |

The spread is wide. Text work is cheap, while video, at about 40 credits per 15 seconds, is the fastest way through a month's allowance. A basic website build is listed at about 15 to 40 credits; Sintra's own pages give much higher figures, 300 credits or more, for complex builds, and costs rise with more images, video and rewrites. Reasoning depth matters as well: the chat box offers Spark, Smart and Pro, and deeper thinking uses more credits. Every team member draws on the same pool.

When credits run out, helpers stop or are restricted until the next reset unless you upgrade. A second ceiling sits in the Terms: a monthly usage allocation worth about 16 million GPT-5 input tokens, after which service moves to lower-tier models and prompts an upgrade. Extra credits come as recurring, non-refundable upgrades of the subscription, not one-time packs. The usage log in credit settings shows what each action cost. Sintra can change credit costs with reasonable notice, and it has said on Trustpilot that automations set up during onboarding may keep running and using credits. Check which ones are on.


> 💡 **Prove a prompt before scheduling:** Run a prompt in chat until the output is clean, then turn it into a scheduled task, since scheduled runs skip approval and cost credits each time.


## Where the AI employees break down

Sintra admits hallucinations cannot be removed completely, including a helper inventing tasks or abilities it does not have [4]. Its advice is specific prompts, checking output, retrying in a new chat and keeping context in Brain AI. The Terms go further: outputs may be inaccurate, biased or fictional, and every output and agent action needs human oversight. Treat a helper's report that it finished something as a claim. Confirm it in the connected app.

The workflow ceiling is low by design. Complex multi-step chained workflows are not yet available, and the pricing page says Sintra is not for complex AI workflows, AI coding or fully automated publishing. There is no public API. The 1,000+ integrations run through Composio, but many are read-only by default; writes in tools such as HubSpot, Salesforce or Slack depend on the current scope and are not guaranteed. The built-in browser added in 2026 can log into third-party apps and act there, and what it does counts as your action.

Role by role, the gaps are concrete. Seomi advises but cannot edit your site, as covered in [Penn and Seomi](/articles/sintra-penn-and-seomi). Commet builds one static website per workspace and is not an eCommerce platform. Emmie drafts campaigns you send from your own email platform. Cassie has no live chat and no automated DM replies, and nothing answers the phone. Teams get unlimited members but a single role, the owner. Mobile lacks parallel chats and per-helper settings, with no live sync between web and app.


## FAQ

**Does Sintra train AI models on my business data?**

Sintra says it does not train models on your data, and its Privacy Policy bars its AI providers from training their own models on your personal data. Its Terms do allow de-identified, aggregated usage data to be used to improve the service.

**Can my team share the same AI employees?**

Yes. Team members are unlimited, get their own logins and share the workspace's Brain AI and shared integrations, while Gmail, Outlook and Notion connections stay personal and helper chats stay private per user. They also share the workspace's 250 monthly credits.

**What languages do Sintra's helpers write in?**

Sintra says its helpers work in 100+ languages. The web interface itself is available in 12 languages.

**What happens to my helpers and Brain AI if I cancel?**

Access and remaining credits continue to the end of the paid period, and you can resume a canceled plan before it ends at no extra charge. After that you can resubscribe at any time to pick the helpers up again.


## Getting real work out of a Sintra workspace

Build the workspace in the order the product rewards. Load Brain AI by hand with exact brand text, connect only the integrations your helpers will use, and start with chat drafts that queue for approval. Turn a prompt into a scheduled task only after it has produced clean output several times, because that is where the approval step disappears. Read the usage log weekly in the first month, and save video and website requests for when you know the remaining balance. Knowledge first, drafts second, unattended runs last.
