Quick summary

Buffer's custom captions feature lets you write platform-specific post text — including hashtags, emojis, and mentions — directly within the New Post composer and schedule or queue content across all connected social channels in one workflow.

Steps

Log in to Buffer and select your social media account from the all-channels view.
Click "New Post" to open the post composer.
Type your custom caption, including hashtags, emojis, or mentions.
Customize the caption individually for each platform as needed.
Click "Add to Queue", "Schedule", or "Share Now" to publish your post.

📌 Why this matters

Creating platform-specific captions is essential for maximizing engagement across social media channels like Instagram, LinkedIn, and X. Buffer's custom captions feature lets social media managers tailor post copy — including hashtags, emojis, and mentions — for each network without duplicating effort. By combining caption customization with queue scheduling and instant publishing in a single composer, Buffer eliminates the need to switch between platforms or tools. This makes Buffer an ideal social media scheduling solution for teams and creators who manage multi-channel content at scale.
