Personas help you organize content when managing multiple brands, clients, or personal accounts.

What are Personas?

A Persona is a grouping of social media accounts that belong to the same brand or identity. For example:

  • Brand A: Instagram account + TikTok account + Twitter account
  • Brand B: Different Instagram account + Different LinkedIn page
  • Personal: Your personal accounts across all platforms

Creating Personas

  3. Name your persona (e.g., "Coffee Shop Brand")
  4. Link relevant social media accounts
  5. Save and start posting with that persona

Pro Tip: When creating a post, select the persona to automatically post to all accounts associated with that brand.

Troubleshooting & FAQs

My account won't connect

Try these steps:

  • Clear your browser cache and cookies
  • Disable ad blockers temporarily
  • Make sure you're logged into the social media platform first
  • Try using a different browser
  • Check if the platform's OAuth service is down

My post failed to publish

Common causes:

  • Token expired - reconnect the account
  • File size too large - compress your media
  • Caption too long for the platform
  • Platform API rate limits - try again in a few minutes

Can I edit a post after publishing?

Unfortunately, most social media platforms don't allow editing published posts through their APIs. You would need to delete and repost on the platform directly.

How do I cancel my subscription?

Go to your Subscription page and click "Cancel Subscription". You'll retain access until the end of your billing period.

Is my data secure?

Yes! We use industry-standard encryption, OAuth 2.0 for authentication, and never store your social media passwords. Read more on our Security page.
