Use Buffer's AI Assistant for In-App Caption Drafting

What This Does

Buffer's built-in AI Assistant lets you generate, rephrase, and shorten captions directly inside the post creation workflow — so you can go from idea to scheduled post without opening another app.

Before You Start

• You have a Buffer account (AI Assistant available on all paid plans; limited on free)
• You're logged in at buffer.com
• You have your content calendar or topic list open

Steps

1. Open the post creation panel

From the Buffer dashboard, click New Post or click the + icon in the queue view. The post composer opens.

2. Find the AI Assistant

Look for the AI Assistant tab above the caption text box — it appears as a small wand icon or "AI Assistant" label, usually in the toolbar above where you type your caption. Click it.

3. Choose your action

The AI Assistant offers several options:

• Write a post — Generate a caption from a prompt
• Rephrase — Rewrite an existing caption in a different style
• Shorten — Cut a caption that's too long
• Expand — Develop a short idea into a full caption

For a new post, select Write a post.

4. Enter your topic and tone

Type a brief description of the post topic (e.g., "announcing free shipping through the end of the month for our candle shop") and select your tone: Excited, Conversational, Persuasive, or Informational. Click Generate.

5. Use the result

Buffer generates a caption. Click Use this post to load it into the composer. Edit the text, add your hashtags, select your social profiles, and schedule.

Real Example

Scenario: You manage social for five small businesses and need to draft 15 posts across accounts this morning. You used to write each caption in a separate doc.

What you type/do: In Buffer's composer for a local plant shop → AI Assistant → Write a post → "highlighting a rare monstera thai constellation plant that just arrived in stock, limited quantities" → Tone: Excited → Generate → review → add 5 hashtags → schedule for 11 AM Thursday on Instagram and Facebook.

What you get: A caption draft ("If you know, you know — the Thai Constellation is back. Only 3 in stock and they never last...") ready to edit in under 2 minutes per post.

Tips

• The Rephrase option is useful when you have a caption that's technically correct but feels flat — it generates a fresh angle without starting over.
• If you're generating captions for a platform with character limits (Twitter/X), use Shorten to bring the caption down to size in one click.
• Buffer's AI doesn't store brand voice between sessions, so for accounts where tone is critical, always note: "Brand is [adjective], never says [forbidden word], always mentions [key detail]" in your topic description.

Tool interfaces change — if a button has moved, look for similar AI/magic/smart options in the same menu area.
