Out of Marblism's roster of AI employees, Penny is built specifically for one job: turning "we should really publish more" into an actual content pipeline.

What Penny does

Penny, Marblism's AI blog writer

Keyword research before writing

Penny works from a keyword database of more than a billion terms, and uses it to identify specific, lower-competition phrases relevant to a given business, rather than generic topic ideas. Each post is built around a real search term instead of a guess at what might be useful.

Writing that matches the site's existing voice

Penny reads what is already published on a site and adjusts tone and phrasing to match it, rather than producing generic AI copy. Drafts can be reviewed and edited before publishing, or set to auto-publish directly to WordPress, Webflow, Shopify or Wix.

Built for AI search, not just Google

Penny structures posts for how people increasingly search now, including asking tools like ChatGPT directly rather than typing into a search bar, so content is built to surface in both.

Where it fits in the workflow

All conversations with Marblism's AI employees

Penny sits alongside Marblism's other AI employees (Eva for inbox management, Sonny for social media, and others) in a single conversation-based dashboard, rather than as a standalone tool.
