How many campaigns can I run at the same time?

You can have as many campaigns as you like in AI AutoPost. A common setup is one campaign per category, each with feeds about its topic, which is also how Auto Setup and the starter campaigns are built.

What really matters is how many posts your campaigns create together:

• Each post rewritten with AI uses 1 credit. Posts without AI use no credits.
• To estimate your need, add up the posts per day of all AI campaigns. For example, 6 campaigns posting every 2 hours is about 72 credits a day.
• The Daily Credit Limit in Settings caps the credits used per day. When it is reached, AI campaigns pause until midnight and then continue on their own.

All live campaigns are checked every minute, and only one check runs at a time, so two runs never post the same article twice. On quiet sites, a real server cron job keeps many campaigns on time. See How scheduling and cron work.
