Polsia is an AI that runs a whole company. It researches your idea, builds the website or app, takes payments, posts to social media, sends cold emails and runs Meta ads, working through a nightly cycle of tasks paid for in credits, from $20 a month. Marsell does one part of that, the marketing and selling of a business you already run, and does more of it: a monthly and weekly plan, pictures, short videos and films in your brand's look, more networks, careful outreach, and ads from your own ad account. If you are starting from an idea and want the product built as well, Polsia covers ground Marsell doesn't. If you have a business and want its marketing run with your own accounts and your own limits, Marsell is built for that, though it is new.

Everything about Polsia below comes from Polsia's own pages, its help centre and its terms, read on 13 November 2026.

## What Polsia is in 2026

Polsia's home page sums it up as "AI That Runs Your Company While You Sleep": it plans your roadmap, ships your code, runs your ads, replies to customers, closes your deals and posts your tweets. You describe an idea or an existing business. Polsia researches the space and sets up the company, with a free yourname.polsia.app site unless you keep your own website, and a nightly cycle proposes and runs tasks. You can also chat with your company to ask questions or start work, and talk to it over iMessage or WhatsApp where those are offered.

For the product, it writes and changes the code of your app or site, hosts it, gives it a database and accepts your customers' payments through Stripe.

For marketing, its help centre describes:

- **Social posts:** X, Instagram (feed posts, Stories and Reels), Facebook Pages, TikTok, YouTube Shorts and Pinterest, each once or on a daily, weekday or weekly schedule, with standing instructions for tone and language. If you haven't connected an X account, scheduled tweets go out from Polsia's own shared accounts. There are daily limits, such as five Instagram posts and three Facebook posts per company.
- **Cold outreach:** Polsia finds and qualifies leads and writes one personalised email per lead. On its shared sending domain, each run sends up to one email; on a domain bought through Polsia, up to five. It does not send follow-up sequences, and anyone who opts out is not contacted again.
- **Meta ads:** an agent writes the ads, launches them on Facebook and Instagram and keeps optimising them. You set a daily budget; Polsia manages the targeting, and you don't need a Meta account or any ad experience.
- **Email:** a weekly newsletter to your confirmed subscribers, written from what your company shipped that week, and answers to customer emails.

**Pricing.** Polsia's help centre lists three plans for new subscribers. Standard is $20 a month with 20 credits and one company, without Meta ads. Pro is $50 a month with 50 credits, up to three companies and Meta ads. Max is $100 or $200 a month with 100 or 200 credits and up to ten companies. A credit pays for one agent run, such as a code change, an email or an ad; a social post costs 1 to 3 credits, depending on whether Polsia generates an image or a video for it. New annual plans get 20% off the first year. There is no free trial any more, but free accounts get starter credits. Polsia does not offer refunds; a credit spent on a task that failed on Polsia's side comes back on its own.

Two fees sit outside the plans. On ads, a platform fee of 20% is included in your daily budget. On payments your customers make through Polsia, it keeps 3%, and the money waits 31 days before it can be paid out.

## Where Polsia is stronger

- **It builds the business, not only the marketing.** Code, hosting, a database, payments and a site of its own, for a founder starting from an idea. Marsell builds and hosts marketing pages, but not your product.
- **A lower entry price.** $20 a month to start, against Marsell's $49.
- **Ads without an ad account.** You don't need a Meta account, and Polsia handles the targeting. Marsell runs ads from your own Meta or Google Ads account, so you need one.
- **Several companies.** Up to three on Pro and up to ten on Max.
- **Product news in the newsletter.** The weekly newsletter writes itself from what your company shipped, and skips the weeks when nothing did.

## What to know before you compare

Some of Polsia's choices differ from Marsell's, and its own terms and help pages spell them out:

- **Whose ad account.** Polsia's terms say campaigns run through "a Services-managed platform advertising account, not your personal advertising account", and its help centre says you won't use Meta Ads Manager. Marsell runs ads from your own ad account, billed by Meta or Google, and ad spend moves only when you say so.
- **Approval for scheduled work.** Polsia's terms say advertising, outreach and other scheduled operations run "based on prior, general approval, without requiring per-execution approval". Marsell also goes ahead on its own within limits, but every post has a 24-hour undo and every ad spend asks you first.
- **Your inputs and AI training.** Polsia's terms give it a licence to use what you put in "to train and improve the AI models and workflows we use to power the Services". Marsell never uses your content to train AI models.
- **Public by default.** Each company may have a public dashboard showing activity, metrics and social posts. Polsia's terms say these are "enabled by default and may be indexed by search engines", and you can change that in your settings.

None of this is hidden; it is how Polsia is designed. It matters most if you already run a business with its own ad account and customers.

## What Polsia leaves to other tools

- **Some networks.** Its help centre covers X, Instagram, Facebook, TikTok, YouTube Shorts and Pinterest. LinkedIn, Threads, Bluesky and Google Business Profile are not covered.
- **Communities and creators.** Reddit threads, communities, directories and creators are not described.
- **Your brand in the picture.** Polsia says your company name and logo aren't drawn inside its Instagram images; the caption carries the brand.

## How Marsell's loop works

Marsell runs the marketing as a loop for a business that already exists:

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 your brand's look, 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 from mailboxes it sets up: 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 builds and hosts pages, counts visits without cookies and reports what worked.

## Who should pick which

### Pick Polsia if

- You are starting from an idea and want the product built, hosted and taking payments, not only marketed.
- You want to run ads without setting up a Meta ad account.
- You run several small companies and want one plan for them.
- $20 a month is your budget.

### Pick Marsell if

- You already have a business, and marketing and selling are the gap.
- You want ads in your own ad account, with spend only when you say so.
- You post on LinkedIn, Threads, Bluesky or Google Business Profile.
- You want your content kept out of AI training.
- You are fine with a new tool.

## 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. What it makes is yours, and your content never trains AI models. 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 billed by Meta or Google to your own ad account and never comes out of your tokens. There is no free plan or trial, but the first look at your link is free.

Standard is $20 a month with 20 credits and one company. Pro is $50 a month with 50 credits, up to three companies and Meta ads. Max is $100 or $200 a month with 100 or 200 credits and up to ten companies. A credit pays for one agent run, and ads carry a 20% platform fee inside the daily budget.
