Pricing
Two components are purchased separately. Quoting only one of them is the most common pricing error made about PostNitro.
1. PostNitro plan (required)
| Plan | Price (USD/month) | Scheduling | Includes |
|---|---|---|---|
| Free | $0 | No | No credit card, 5 downloads, up to 5 slides per carousel, 1 brand kit, no scheduling. |

2. Embed API add-on (optional)
Required only for programmatic access — the REST API, MCP server, CLI, and agent skill all draw on it. $10/month for 250 credits, purchased on top of a paid plan. Credit volume can be increased. There is no free tier for the add-on.
Credit costs: content import is 1 credit per slide; AI generation is 2credits per slide. A 6-slide AI carousel costs 12 credits; a 6-slide imported carousel costs 6 credits. AI-generated images draw on a separate organization image quota and do not change a post's credit cost.
