AI Ad Agent (Mark)

Mark is the AI agent in Arcads. Describe the ad you want in plain language and Mark picks the models and tools, makes the ad, edits it and can publish it.

Written by Romain Torres

What it is: the AI agent built into Arcads. Tell Mark what ad you need in your own words, and it picks the models and tools, generates the ad, edits it and can publish it.

What you can do:

  • Get a video ad from a short brief, for example "a 20-second UGC-style ad for our protein bar, 9:16, US audience"

  • Make static ads, one at a time or in a batch

  • Make an ad from your own B-roll footage

  • Replicate a winning or reference ad for your brand

  • Create a recurring character for a series of ads

  • Edit on a timeline: layers, audio, picture-in-picture, trims, text and filters

  • Analyze a Meta campaign, clone the winning ad and publish a new Meta ad

  • Research what is working on TikTok, Instagram and X, and find real UGC creators

  • Set up routines that run on a schedule, daily, weekly or every few hours

How Mark learns your brand: when you add a new brand, Mark reads your website, researches the brand and fills in its brand memory: overview, products, brand voice, target audience and more. You can edit it any time in the Brain panel.

Personalization: Custom Instructions (up to 2,000 characters) apply to every message, for example "Use a 9:16 aspect ratio by default" or "I always target a US audience". Presets set the tone, the default video resolution and whether Mark checks with you before editing a video.

Benefits:

  • No need to know which model to pick or where each setting lives

  • Available on every plan and in the 72-hour free trial

  • Works in Slack too, once the workspace owner connects it

  • Works next to Studio (pick every setting yourself), Workflows (repeat a pipeline) and the Arcads MCP (work from Claude or ChatGPT)

Good to know: generations use their normal credits, and chat turns with Mark are also charged by token usage.
