What Social9 is
Social9 is a web-based platform for creating and managing social media content with AI. It generates posts, captions, hashtags, bios, carousel text, threads, and ad copy, with formatting for different platforms. Brand guidelines and sample content can inform a custom brand voice, and tone checks help keep content consistent. Social9 lists localization in more than 50 languages with cultural adaptation. Its publishing channels include Instagram, Facebook, LinkedIn, X, TikTok, YouTube, Pinterest, Threads, Bluesky, Mastodon, and Google Business. The platform also lists AI-optimized scheduling, a visual content calendar, engagement predictions, and ROI reporting dashboards. It integrates AI models from OpenAI, Anthropic, Google, Meta, Perplexity, and Mistral, selecting a model for each task. The permanent Free plan costs nothing and includes 20 credits monthly, estimated at about five post generations. Pro costs $20 a month, and Premium costs $50 a month; Enterprise pricing is custom. Social9 states that customer content is not used to train public AI models and that brand voice customization is isolated to the customer’s account.
