What it does
PostNitro is a browser based AI carousel maker. It builds multi slide carousels, single image posts and animated video from a topic, text, an article URL or an X post. Templates are editable, and a brand kit applies fonts, colors, logos and headshots. A freeform canvas supports custom sizes, infographics, backgrounds and AI images per slide. Posts can be scheduled and published natively to LinkedIn, Instagram, TikTok, Threads, Facebook and Pinterest, or exported as PNG, PDF or MP4. Integrations include Zapier, Make, an embed SDK, REST API, MCP server and CLI. Plans, documentation and a support email are on the site.
The editor can be opened without signing up, and nothing is saved unless an account is created. The site states it is free to start with no credit card required. Scheduling supports separate captions per network, Instagram stories, TikTok slideshows or reels, and LinkedIn document carousels. A planner shows drafts and scheduled posts together. Claude and ChatGPT connectors sign in with OAuth rather than an API key. Documentation covers API keys, scheduling endpoints, brand kits, social accounts and templates. Support is offered by email at [email protected] and through documentation and in-app chat.
