Marsell vs Helena: two AI marketers that act on their own, compared

Helena by Enrich Labs plans and runs SEO, social, ads and email from $39 a month. Marsell plans, makes, publishes and finds buyers. What differs and who fits.

By Ilya Arbabi, 12 November 2026

Helena, made by Enrich Labs, is an AI marketing agent that learns your brand, builds a strategy from your data, and acts across SEO, social media, ads and email, then sends you a report every morning. Plans start at $39 a month, with a 3-day free trial. Marsell is close to it in spirit: it learns your business, then runs on its own. The differences are in where each puts its effort. Helena goes deeper on paid ads (Meta, Google and TikTok), email flows in Klaviyo and Mailchimp, and shop data from Shopify. Marsell goes further on making (pictures, short videos and films), on the number of networks it publishes to, and on finding buyers in communities and search, with careful prospect emails. If ads and email drive your sales, Helena is the stronger pick. If you need content made and buyers found, Marsell is built for that, though it is new.

Everything about Helena below comes from Enrich Labs' own pages, read on 13 November 2026.

What Helena is in 2026

Enrich Labs describes Helena as "the AI marketing agent that learns your brand, builds a personalized strategy, and takes action autonomously across SEO, social, ads, and email", and then reports back to your inbox every morning. Its product page lists what you get:

Its integrations include Google Analytics, Google Ads, Meta Ads, TikTok Ads, Shopify, WordPress, Webflow, Klaviyo, Mailchimp, Instagram, Facebook, LinkedIn, X and TikTok. Its solopreneur page adds engagement agents that run reply rounds and answer routine comments.

How much it does alone. For SEO, Enrich Labs says "You can review before publishing or let her publish automatically based on your preferences." Its Enterprise page says you set the autonomy per workflow, "from propose-only to fully autonomous", and that on ads "underperformers get paused automatically" inside daily budget guardrails. The product page lists a propose-only mode under its Enterprise guardrails; the pricing page doesn't say which plans include it.

Pricing. On 13 November 2026 the pricing page listed:

A social post, an image or an ad creative costs 1 credit, a blog article 2, an email campaign or a TikTok slideshow 3, and a video of 4 to 12 seconds 12. Credits reset on the 1st of each month and you can top up. The page says annual billing saves 25% but doesn't show annual prices. Every plan starts with a 3-day free trial, which Enrich Labs' terms say turns into a paid subscription unless you cancel, and its terms say fees are non-refundable unless stated otherwise. Enrich Labs says your data is never used to train AI models.

How Marsell's loop works

Marsell runs marketing and selling as one loop:

  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, and tells you every morning what went out, by email, Telegram or Slack.

Both send a morning report. The bigger difference is money: Helena moves ad budget to winners inside the guardrails you set, while Marsell moves ad spend only when you say so.

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.
