postnitro.aiAbout PostNitro
PostNitro generates carousel posts for LinkedIn, Instagram, TikTok and Threads from a topic, a URL, pasted text or a Twitter thread, then schedules and publishes them. The AI writes the slide copy, applies a template and formats the output for each platform's aspect ratio, and you can fine-tune before exporting as images or a PDF or pushing straight to a connected account. Over a hundred customisable templates ship with it, and brand controls cover custom colour palettes, uploaded fonts, custom font sizing, watermarks and CTA QR codes, with the ability to build and save your own templates on paid tiers. The model selection is unusually transparent for a content tool: the plan comparison names exactly which models each tier can reach, from GPT 5.4 Nano on free through GPT 5.4 Mini and Claude Haiku 4.5 on Starter to GPT 5.4, Claude Sonnet 4.6 and Claude Opus 4.7 on Creator and above, with a long list of image models including Nano Banana, Flux 2, Imagen 4 and several Stable Diffusion variants. There is a Claude connector so carousels can be created inside a chat, plus API access from the Creator tier and scheduling to ten social accounts, rising to thirty on Team. The vendor states 82,000-plus creators and embedding into 200-plus social media management platforms. A free tier exists with a watermark, five slides per carousel and five downloads.
