AI employees are specialists, each trained for its own field. Instead of explaining your business to a general chat tool over and over, you work with a team that already knows its job, and you teach it your business once. Sintra AI gives you 12 core AI employees built by Sintra AI. You can also hire AI employees built by the Sintra AI community, or build your own and keep it to yourself or share it with the community. This article introduces every core AI employee, shows how to hire one from the community, and explains what you need to know before you build your own.

Who does the work?

You can chat one-to-one with a specific AI employee when you know who should do the job, or start in Team chat on the homepage and your request is routed to the right specialists.

Where?

In the web app (app.sintra.ai) and the mobile apps for iPhone, iPad and Android. They sync, so you can start a task on your computer and check on it from your phone.

All 12 core AI employees are included on every plan. They share your Brain AI and your connected apps.

Buddy helps you grow the business: go-to-market plans, competitor analysis, pricing and growth strategy, marketing plans, product launches, new revenue ideas, and updates for investors or partners. For example: "Compare our pricing and features with our top three competitors and suggest where we can stand out."

Cassie writes replies to customer emails and comments, builds FAQs and product guides, and designs support templates and workflows from the policies and answers in your Brain AI. She also runs two built-in automations: the Inbox Manager, which sorts your Gmail or Outlook inbox and drafts replies, and the Facebook Commenter, which drafts replies to comments on your Facebook Page. Replies are drafts for you to review, never sent on their own. For example: "Write an FAQ for our website based on our refund and delivery policies."

Commet builds and edits your Sintra AI website, writes product pages and descriptions, reviews your store and conversion funnel, and helps with merchandising and Shopify updates. You change your website by telling Commet what to change. For example: "Add a new section to my homepage with three customer testimonials and a contact button."

Dexter turns your numbers into clear answers: sales and KPI reports, spreadsheet analysis, trends, charts and forecasts. Share a spreadsheet or connect your tools and ask what the data means for your business. For example: "Analyse last quarter's sales in this spreadsheet and tell me which products are growing and which are slowing down."

Emmie writes newsletters, welcome and nurture sequences, abandoned-cart and win-back emails, and full campaign plans. For example: "Write a three-email abandoned cart sequence for my online store, with a 10% discount in the last email."

Gigi helps you organise yourself: productivity systems, daily plans, routines, goals, and meal and workout plans. If you connect Strava, Gigi can base workout plans on your recent activities. For example: "Make me a weekly vegetarian meal plan that's high in protein, with a shopping list."

Milli researches prospects and writes cold outreach, follow-ups, sales scripts and proposals. With Gmail or Outlook connected, outreach can be sent from your own inbox, with your approval. For example: "Draft a cold email and two follow-ups introducing our bookkeeping service to local restaurants."

Penn writes ad copy, blog posts, website copy, video ad scripts, promotional materials and brand messaging. For example: "Write three versions of a Facebook ad for our new vegan snack range, aimed at busy parents."

Scouty writes job posts, sets CV screening criteria, screens CVs you share, prepares interview questions and structures, and creates onboarding checklists for new hires. For example: "Write a job post for a part-time marketing assistant and a list of interview questions for the role."

Seomi audits websites for SEO issues, researches keywords, plans content for search and checks how visible your business is in AI search. Seomi can audit any public website, even one Sintra AI didn't build. For example: "Audit my website and list the top five SEO fixes, starting with the most important."

Soshie creates posts, captions, campaigns, content calendars, social images and short videos, written from your Brand Kit and Brain AI. AI employees can create, schedule and publish posts to your connected social accounts, with your approval. For example: "Plan a week of Instagram posts for our autumn menu, using the photos in my Brain AI 'Autumn' folder."

Vizzy handles scheduling, reminders, research, document prep and general admin. Vizzy also runs two built-in automations: the Meeting Notetaker, which joins your online meetings and sends a summary with action items, and the Daily Summarizer, which sends a short daily overview of your calendar and inbox. For example: "Research three hotel options near the conference centre in Berlin for next Tuesday and put them in a short comparison."

Tip: not sure who to ask? Start in Team chat and your request goes to the right AI employee.

Pick an AI employee and describe the outcome you want in one message: the goal, who it's for and the format. Attach anything useful, such as a past post, a spreadsheet or a photo. The AI employee asks follow-up questions if something is unclear. For example: "Penn, write five Instagram captions for our autumn menu. Keep each under 40 words and end with a question."

Team chat is on by default. A Team Leader plans the work, hands each part to the right specialist and pulls the results together. For example, Buddy sets the strategy, Penn writes the copy, Soshie turns it into posts and Emmie writes the launch emails. For example: "Plan a product launch for our new candle range: a short strategy, three launch emails and a week of social posts."

You can run several chats at the same time. Each chat shows its status, and you're notified when something needs your input or approval. You can leave a chat or close the app while the work continues.

Anything that sends, publishes, schedules or spends shows a card for you to approve first. AI employees won't publish or send anything externally without your approval, unless you deliberately set up a scheduled task to do it without your approval.

When there's no integration for a tool, or a job simply happens on a website, an AI employee can open a browser from chat and do it the way you would: open pages, click through menus, fill in forms and read what's on screen. That opens up a lot of everyday work: collecting an order list from a supplier's portal, checking prices on several sites, or going through your own website's sign-up or checkout flow as a customer would and reporting where people might get stuck. You can watch it work live. If a website needs you to log in, the AI employee pauses and you log in yourself: it can't log in for you. Browser tasks can also run as scheduled tasks, as long as the website doesn't need a login. For example: "Go through the checkout on my website as a first-time customer and give me a short UX review: what's confusing, what's slow and what you'd fix first."

Once a task works well in chat, ask the AI employee to repeat it. For example: "Run this every Monday at 8 am and email me the summary." Review the automation card and approve it. You'll find it in the Tasks tab, where you can pause, edit, run or delete it.

AI employees work in more than 100 languages. Write in your language and they reply in it, and they can draft replies directly in your customer's language. To make it stick, tell your AI team which language and spelling to use and save it as a rule. For example: "Always write in UK English. Save this as a rule."

Languages AI employees work in include: Afrikaans, Albanian, Arabic, Armenian, Aymara, Azerbaijani, Bashkir, Basque, Bengali, Bosnian, Bulgarian, Burmese, Catalan, Cebuano, Cherokee, Chinese (Simplified), Chinese (Traditional), Croatian, Czech, Danish, Dutch, Dzongkha, English, Esperanto, Estonian, Finnish, French, Galician, Georgian, German, Greek, Guarani, Gujarati, Hausa, Hebrew, Hindi, Hungarian, Icelandic, Igbo, Irish, Italian, Japanese, Javanese, Kannada, Khmer, Korean, Kyrgyz, Lao, Latvian, Lingala, Lithuanian, Luganda, Malagasy, Malayalam, Maltese, Maori, Marathi, Mongolian, Nepali, Norwegian, Odia, Pashto, Persian, Polish, Portuguese, Punjabi, Quechua, Romanian (including Moldovan), Russian, Sango, Sesotho, Shona, Sindhi, Sinhala, Slovak, Slovenian, Somali, Spanish, Swahili, Swati, Swedish, Tajik, Tamil, Telugu, Thai, Tibetan, Tigrinya, Turkish, Turkmen, Ukrainian, Urdu, Uzbek, Welsh, Xhosa, Yiddish, Yoruba, Zulu.

The app interface itself is available in a smaller set of languages. To change it, open your profile settings in the bottom-left corner, scroll to Language and choose your language.

For the list of app languages, see What languages is the UI (Interface) available in?.

The Sintra AI marketplace has AI employees built by other Sintra AI users for very specific jobs. Hiring AI employees is free. A hired AI employee joins your team like any other: it reads your Brain AI and works in your connected apps.

A hired AI employee adds new skills and expertise to your AI team without adding to your bill. Credits are only used when AI employees work, whoever built them. And because a specialist already knows how to do its job, it usually needs fewer steps to get there: the better an AI employee fits the task, the fewer credits the task uses.

How to hire one:

You can also ask in chat. For example: "Find an AI employee in the marketplace that writes property listings, and hire it."

Making it yours: you can rename a hired AI employee, edit its description and boundaries, and add your own rules, skills and personality notes on top of its original setup, so it follows your way of working. Its look and its role stay as its creator set them. To make changes, ask in chat. For example: "Rename Remi to Nalo and add a rule: always quote prices in EUR." A new name can't be a core AI employee's name or the same as another AI employee in your workspace. Renaming doesn't affect its link to the marketplace listing.

Removing it: a hired AI employee is dismissed rather than deleted. The person who hired it, or a workspace owner or admin, can dismiss it. Your rules, skills and notes for it are permanently lost, but you can hire it again later.

If it leaves the marketplace: if its creator unlists it, you keep it, together with your rules, skills and notes. Its card shows a Delisted badge. Your existing chats and scheduled tasks keep working, but you can't start new chats with it or get newer versions. If Sintra AI removes a listing for a policy reason, it stops working in every workspace that hired it, and its scheduled tasks can't run, so pause or delete them in the Tasks tab. For serious policy breaches, it's removed from those workspaces altogether.

Your copy is yours: each business that hires an AI employee gets its own copy. Your business knowledge stays in your workspace.

Tip: hire one when you need a specialist you don't want to build yourself, and when none of the core 12 covers the role.

Every AI employee, whether core, hired or built by you, is made of three layers. Getting them right is what makes a custom AI employee reliable, so it's worth understanding them before you start building. The soul file is the foundation, skills add what the AI employee can do, and rules sit on top with the highest priority.

Soul file: who the AI employee is. This is the foundation: its role, personality, expertise, rules and boundaries. It's always active. The builder writes it with you when you create an AI employee.

Skills: what the AI employee can do. A skill is a step-by-step workflow for one job, such as a quarterly business review or a blog post framework. The AI employee uses a skill automatically when your message matches what the skill is for. An AI employee can have as many skills as you need, and each skill can be up to about 400,000 characters long. You can create a skill by describing the workflow in chat, or import one (see Step 5: Add skills).

Rules: how the AI employee should behave. Tell your AI employee in chat how it should behave, and it saves these as rules that are always active, such as "write in plain, direct language" or "our fiscal year starts in April". You can also add personality notes, which go on top of its default style. For example: "From now on, always write in plain, direct language. Save this as a rule."

Build your own AI employee for a job the core team doesn't cover, such as a quote assistant, a property listings writer, a warranty checker, a tender writer, or "a second you" that works the way you do. Agencies can give custom AI employees their own names and avatars to present work under a client's brand.

Ask in chat to create a new AI employee, and describe the role in a sentence or two. For example: "Build me an AI employee called Tova who writes quotes for our kitchen renovation jobs, using our price list." Building is available on every plan and uses credits (see Credits).

The builder asks about the role, responsibilities and how it should work, then writes its soul file and rules (see Before you build: how soul files, skills and rules work together). Tip: be specific about what good work looks like and what it should never do.

Pick a short, person-like name that isn't one of the core 12. Then design your AI employee's look in the avatar builder by choosing a pose, features and accessories. You can change it as often as you like before you save it, and come back to change it later. Only AI employees you build can change their look; core and hired AI employees keep theirs.

Add a short description of what it does and set its boundaries: what it must not do or say. People see both in the app, and on the marketplace if you publish it. They're summaries, not instructions: what your AI employee actually does comes from its soul file and rules. So a boundary only takes effect if it's also saved as a rule.

Keep the three separate: don't repeat the role in the description, and don't turn a capability into a boundary or the other way round.

Writing a good description

Good: "Creates social media campaigns, writes posts, and manages content calendars across platforms"

Avoid: "An amazing AI social media manager that helps you with all your marketing needs!"

Writing good boundaries

Good: "Never publishes without your approval. Won't spend more than $500 on ads. Never shares customer personal data."

Avoid: "Doesn't do accounting. Only does social media." This only repeats the description.

Tip: when you edit your AI employee later, change the description only if what it can do changes. Adding rules or skills doesn't need a new description.

Add the workflows it should run the same way every time. For example: "Add a skill: when I send job measurements, check the price list, build a quote in our template and list anything missing."

You can also import an existing skill by pasting a link, such as from GitHub, and asking to install it. Sintra AI adapts it to work in Sintra AI, runs a security check and then installs it. Skills from your personal skill library can be copied into an AI employee too. The two copies are then separate, so a later change to one doesn't affect the other.

Tip: only bring in skills from sources you trust. The safest way to use someone else's skill is to check it does nothing harmful, then share it as a reference and ask Sintra AI to build your own version of it.

Your AI employee is saved to Brain AI as its own folder, with its soul file, rules and skills, and it appears in your list of AI employees. It works just like the core ones: it reads your Brain AI, works in your connected apps and can run scheduled tasks. You can edit its name, avatar, instructions and behaviour at any time by asking in chat.

Your privacy while building: building an AI employee is the one time Brain AI is not used. It learns only from what you tell it and public web research, unless you point it at a Brain AI folder.

You choose whether to keep your AI employee to yourself or publish it to the Sintra AI community. If other businesses use it, you receive a revenue share you can cash out. Publishing shares the AI employee, not your business knowledge, and every business that hires it gets its own copy. Your original setup stays private: businesses that hire it can't see or copy it.

Ask in chat to publish your AI employee. For example: "Publish Tova to the marketplace." Before anything is submitted, Sintra AI removes your own business details from it and runs a brand and quality review.

Add its categories, sample conversations, what it can do and example tasks. A clear description and boundaries help here too (see Step 4: Add a description and boundaries).

A Sintra AI reviewer checks every listing before it goes live, usually within 48 hours. If it's declined, you get feedback and can fix it and resubmit.

You earn from the credits that businesses spend while using your AI employee. Hiring is free, so hiring alone doesn't earn anything. Your share is 30% of Sintra AI's margin on those credits, not 30% of the credits spent. You keep earning from businesses that already have your AI employee, even after you unlist it.

Good to know: payout options are being rolled out gradually, so you may see only the credits option for now.

To unlist your AI employee, choose Unlist on its listing page or ask in chat, and give a reason. Nobody new can hire it after that. Businesses that already hired it keep it, and their existing chats and scheduled tasks keep working, but they can't start new chats or get newer versions. You can't relist it yourself: contact support to put it back up.

Sintra AI reviewers can also take a listing down. If that happens, you're told why and offered help to fix it and resubmit.

AI employees don't talk to your customers on their own, and there's no chatbot or chat widget for your website. The closest options are the Inbox Manager for email, the Facebook Commenter for Facebook Page comments, or a custom AI employee your own team uses to answer questions. You can also set up your own automation to handle incoming enquiries, using a scheduled task and your connected apps. For example: "Every hour, check my inbox for new enquiries, draft a reply to each one from our FAQs and log them in my enquiries spreadsheet." To learn how, see Recurring Scheduled Helper Tasks. AI employees use integrations only for actions that are supported, so connect the apps a task needs before you start it. Browser tasks work on websites and web apps, not on desktop software.

Credits are used when AI employees work, not for having them on your team. Every AI employee, whether core, hired or built by you, uses credits from your workspace's monthly allowance for the work it does. As a rough guide:

Heavy tasks show the cost before you confirm.
