About PostNitro
PostNitro is a web-based AI carousel creation and scheduling platform designed for marketers, agencies, small businesses, and creators who publish on LinkedIn, Instagram, TikTok, X, and Threads. It combines AI copywriting with slide design to transform an idea into a formatted, multi-slide carousel without requiring design skills. Users can generate carousels from a topic, pasted text, a URL, or an X (Twitter) thread/post URL, then select the slide count and refine the output. The tool offers over 100 platform-optimized templates, brand kits, custom fonts, and color palettes for customization, with preview and export options available. Carousels can be scheduled and published directly to supported platforms or exported as PNG/PDF files. PostNitro also provides a public API and integrations like Zapier, enabling users to embed or automate carousel generation within other tools and workflows. The platform operates on a freemium model, with paid plans starting at $15/month and API credits available separately.
