PostNitro

PostNitro is an AI-powered design engine for social content. It designs carousels, image posts and short animated video on a brand kit, then schedules and publishes them natively to LinkedIn, Instagram, TikTok, Threads, Facebook and Pinterest. The editor supports AI-generated content or freeform drag-and-drop editing, and supports multiple templates and brand kits. It is aimed at creators, agencies and teams who want to turn ideas into on-brand posts without relying on external designers.

PostNitro integrates AI writing and layout with a design editor that applies a brand kit automatically. Users can start from a topic, article URL, text, or an existing post, and the system writes and layouts the slides, then allows further customization before publishing.

The tool offers a free-to-start approach with templates, a drag-and-drop canvas, and native publishing. It supports multiple networks and allows exporting designs as PNG, PDF or MP4 for manual posting if needed.

The platform also provides API, MCP server and CLI options for automation and integration, and allows connecting AI agents like Claude and ChatGPT to drive the same design engine across different interfaces.
