Every article you publish becomes a caption written for social media — not a copy of your headline.
Choosing the provider
Under Post Ping → Settings → AI you choose between OpenAI and Claude and paste your own API key. The cost stays under your control and is usually a few cents per month for a typical blog.
Tone of voice
Pick between professional, casual or informative, and add extra instructions describing your brand. The AI reads the article and writes the caption with hashtags in that voice.
Prefer to write it yourself?
Switch the caption mode to manual and a caption field appears right in the post editor. Nothing is generated automatically.
