Free tools for social media, made for people who post for a living
SocialPost.ai builds free tools for founders, operators, and creators who grow their business on social. Instead of generic spinners, each tool is tuned for the platform it serves: posts formatted for LinkedIn or X, headlines that fit the 220-character limit, captions built to rank on YouTube, and hashtags that match how people actually search.
You can use every tool without an account. There is no credit card, no trial timer, and no export gate on the core result. When you want to schedule, design branded graphics, or track performance, the paid app is there. Until then, take what you need.
One engine behind every tool
The tools share the same model that powers the SocialPost.ai app. That is why the output reads like a person wrote it and fits each platform out of the box, with no prompting. Generate a draft here, then move to the app when you are ready to publish on a schedule and see what lands.
