Brand kit & publishing

Lock your brand once so every render stays consistent, then connect accounts to publish.

Set your brand up once and Krex AI keeps every video, ad, and post on-brand without you re-specifying it each time.

Build your brand kit

Open My Brand. You can set:

  • Brand kit — primary + accent colors, fonts, logo, intro/outro text, watermark.
  • Products — names, descriptions, URLs, and reference images the Product Ad + Copilot pull from.
  • Avatars — saved or generated talking-head avatars (and personal clones).
  • Voices — your preferred TTS voice or a cloned voice.

Pick a brand preset at render time (the brandId) and its colors, logo, and framing are merged into the output automatically.

Connect your accounts

To publish or schedule, connect your platforms under Settings → Connections: TikTok, YouTube, Instagram, and Facebook. Each uses a standard OAuth connect.

Schedule

From any finished render — or from the Automation Coach — choose platforms and a time. Krex AI queues the post and publishes it for you. Want recurring? Use a recurrence (daily/weekly/monthly) or set up an Autopilot program for fully unattended posting.

See Automation & API for the hands-off and programmatic paths.
