Sintra sells AI employees. You get a team of twelve helpers, each named after a role: Soshie for social media, Penn for copywriting, Emmie for email marketing, Seomi for SEO, Cassie for customer support, Commet for ecommerce, Milli for sales, Dexter for data, Buddy for business strategy, Scouty for recruiting, Vizzy as an executive assistant and Gigi as a personal growth coach. You add your brand context to Brain AI once, connect your tools, and ask each helper for work through chat or one-click use cases. The homepage cites more than 40,000 entrepreneurs, work in 100+ languages, unlimited business profiles and a shared workspace for a team.
Vibiz is narrower and deeper. It is a marketing workspace: paste a URL and it extracts your brand kit, then produces ad creatives, product photography, UGC-style video and a month of social posts, builds landing pages and funnels with checkout, and launches and manages Meta and Google campaigns. An inline agent operates the workspace, and nothing spends without your approval.
Breadth. If your week includes support emails, a newsletter, an SEO audit and a sales proposal, Sintra has a helper for each. Vibiz does not write email flows or SEO blog posts.
Price on a long plan. As of October 2026 Sintra X was on sale at $48.50 a month on the 1-month plan, $23.60 on the 3-month plan and $15.60 on the 12-month plan, against list prices of $97, $59 and $52. A single helper is $39 a month. Vibiz Pro is $79 a month, or $63 a month billed yearly.
Languages. Sintra says its helpers work in more than 100 languages, which matters if you sell in several markets.
Finished creative, not a brief. Penn writes Facebook ad copy and scripts video ads, and Vizzy handles image tasks such as background removal. Vibiz produces the ad itself: Meta-ready statics, UGC-style video and product shots from one photo, every one editable by describing the change.
The campaign goes live. Vibiz launches and manages Meta and Google campaigns. The ad budget goes to the platform and the service fee is shown before you approve. Sintra's pages do not describe launching ads.
A page, not page copy. Commet and Penn write landing page copy. Vibiz builds the publishable page or funnel with checkout, so the ad has somewhere to convert.
Approval built in. Every Vibiz post and launch waits for your yes. That suits owners who want automation without surprises.
List the jobs you would hand over in a normal month. If most of them are writing jobs across different parts of the business, Sintra spreads its value across more of them, especially on a 12-month plan. If most of them are marketing jobs that end with something live, an ad running on Meta or Google, a page taking orders, a post on the calendar, Vibiz does more of the actual work.
Watch the commitment either way. Sintra's lowest prices need a 3- or 12-month plan and are shown as sale prices, and the safety net is a 14-day money-back guarantee rather than a trial. See Sintra alternatives for other options, or how Vibiz handles social posts and the MCP server.
