PostNitro

PostNitro is an AI tool for creating social media carousels end to end—from a topic or rough draft to ready-to-post slides. It helps turn ideas into structured, designed carousel posts in minutes, without requiring design skills.

Carousels for Instagram, LinkedIn, and TikTok

PostNitro generates the content and slide structure, then formats the carousel to match common platform requirements. The result is a consistent-looking post that’s easier to publish and iterate on in a content plan.

Templates and built-in editor

PostNitro includes 100+ customizable templates for different carousel formats. You can quickly adjust the design to match your brand, edit text and elements in the editor, and prepare the final carousel for publishing.
