Sintra gives a small business 12 AI helpers, each a chatbot trained for one role: social media, copywriting, email marketing, SEO, sales scripts, customer support, data, a website, a virtual assistant and more. One plan includes all of them, from $15.60 a month on a yearly plan. Its social media helper plans, writes, designs and schedules posts, and shares nothing without your approval. Marsell does one job, marketing and selling, as a loop: it plans the month, makes the posts, pictures, short videos and films, publishes them on its own once it has learned how you like them, finds buyers and emails prospects. If you want cheap help across every corner of the business and like working through chat, Sintra is the better value. If you want the marketing itself to run, Marsell is built for that, though it is new.

Everything about Sintra below comes from Sintra's own pages, read on 13 November 2026.

## What Sintra is in 2026

Sintra calls its helpers AI employees. You add your brand context once, and its Brain AI keeps your voice, colours, images and business details. You connect your tools, type what you need into chat, and Sintra hands the task to the right helper and returns a first draft for approval. Each helper runs as a chatbot, and they pass work to each other: the social media helper, for example, uses the business helper for strategy, the copywriter for writing and the data analyst to check results.

The twelve, as Sintra describes them:

- **Soshie, social media manager:** plans a content calendar, writes posts, makes images and videos, and schedules them to Facebook, Instagram, LinkedIn, YouTube and TikTok.
- **Penn, copywriter:** ads, blog posts, websites, advertorials and email campaigns.
- **Emmie, email marketing:** emails and win-back flows for your subscriber list.
- **Seomi, SEO:** SEO strategy and SEO blog posts.
- **Milli, sales:** cold call scripts, cold emails and pitches.
- **Buddy, business development:** growth strategy, launches and audience analysis.
- **Commet, eCommerce and website:** store setup, product launches, and building and updating your website.
- **Cassie, customer support:** replies to customer questions and Facebook comments.
- **Dexter, data analyst:** calculations, forecasts and reports.
- **Vizzy, virtual assistant:** calendar, meetings and trips.
- **Scouty, recruiter:** job posts and onboarding.
- **Gigi, personal growth coach.**

Sintra says it has more than 1,000 integrations and names Gmail, Google Drive, Google Calendar, Google Analytics, Microsoft, Notion, Shopify, QuickBooks, Facebook, Instagram and LinkedIn pages among them. It works in more than 100 languages, includes unlimited team members, and lets you add a workspace for each business you run.

**Pricing.** There is one plan, Sintra X, with all 12 helpers and 250 credits a month. On 13 November 2026 its pricing page showed $48.50 for one month, $23.60 a month on a 3-month plan and $15.60 a month on a 12-month plan, each marked as a discount from $97, $59 and $52 a month. The longer plans are paid up front ($70.80 for three months, $187.20 for twelve), credits reset every month whatever the plan length, and VAT may apply. Sintra's help centre gives a larger credit package as an example: 600 credits a month for $240 over three months. There is no free trial, but there is a 14-day money-back guarantee on your first purchase.

Sintra's own examples of what credits buy: about 1 credit for a social post written, designed and posted, up to 1.8 for an image made in chat, about 40 for 15 seconds of video, and 30 for a simple website build. It says 250 credits cover social media and day-to-day work, and that you may need more for websites, complex images and video.

Sintra says it suits you if you are solo or a small team, run one to five businesses and "wear too many hats". It says it won't work if you want an enterprise solution, AI coding, complex workflows, an eCommerce tool for more than 1,000 products, or "fully automated AI that publishes without your approval".

## Where Sintra is stronger

For an owner who needs a hand with everything, Sintra has real advantages:

- **Price.** $15.60 a month on a yearly plan covers twelve helpers. Marsell starts at $49 a month.
- **Breadth.** Customer support replies, email, calendar, reports, recruiting, and help with taxes and expenses sit beside marketing. Marsell does marketing and selling only.
- **Languages.** More than 100, against Marsell's 42.
- **Team and businesses.** Unlimited team members on the one plan, and a workspace for each business.
- **A refund window.** 14 days to ask for your money back. Marsell has no free trial; the first look at your link is free.
- **Chat first.** If you like to brain-dump and get a draft back, that is how every Sintra helper works.

## What Sintra leaves to other tools

- **Publishing on its own.** By Sintra's own description, it is not for AI that publishes without your approval, and Soshie shares nothing without your yes. If you want posts to go out while you are busy, you approve them first.
- **Paid ads.** Penn writes ad copy. No ad accounts appear among its integrations, and running ads is not among its listed features.
- **Finding buyers.** Milli writes cold emails, call scripts and pitches, and Sintra lists lead generation and email outreach among its uses. Finding prospects for you and emailing them on a schedule is not described, and Reddit threads, communities, directories and creators are not mentioned.
- **Networks.** Soshie posts to Facebook, Instagram, LinkedIn, YouTube and TikTok. X, Threads, Pinterest, Bluesky and Google Business Profile are not listed.
- **Video volume.** Sintra says the plan's 250 credits may not be enough for complex images and video, and 15 seconds of video costs about 40 credits, so regular video means buying more.

## How Marsell's loop works

Marsell is not a set of chats you hand tasks to. It runs the marketing as a loop, and you ask it for anything from the bar at the bottom of each place when you want to steer:

1. You give it a link to your business (or a line about it, or your own AI sets it up over MCP). It reads your pages, products, public mentions and the way you write, and you correct what it got wrong.
2. It plans the month and the week.
3. It writes the posts and makes pictures, carousels, short videos (motion graphics drawn in code, or AI video) and films, in any of 42 languages.
4. It publishes to Instagram, TikTok, YouTube, X, LinkedIn, Threads, Facebook, Pinterest and Bluesky, plus Telegram and Google Business Profile, from accounts you connect. It learns each kind of post from your first few answers, then posts on its own within daily limits. Every post has a 24-hour undo.
5. It looks for buyers in Reddit threads, communities, directories, creators, search and AI answers, and emails prospects one by one: one checked first email each, one approach a month, and a no is final. It runs small ad tests from your own ad account, and ad spend moves only when you say so.
6. It reports what worked, counting visits without cookies.

- You want help across the whole business, not only marketing, for the least money.
- You like to work through chat and approve each draft.
- You need more than 42 languages.
- You want a money-back window before you commit.

### Pick Marsell if

The two can sit side by side: Sintra for support, email and admin, Marsell for the marketing. If you do that, let only one of them post to each social account.

## Where Marsell fits

Marsell is an AI marketer that markets and sells a business on autopilot. It learns each kind of work from your first few answers, then does it on its own within daily limits. Every post has a 24-hour undo, and you can steer or pause it any time. Money is the exception: ad spend moves only when you say so. It is new, and its first customer is Marsell itself.

Plans are Solo $49, Core $169, Growth $399 and Network $799 a month, each with monthly tokens for the model and media work, and every paid action shows its price in tokens first. Ad spend is paid to the ad network separately. There is no free plan or trial, but the first look at your link is free.
