Captions that stop the scroll. Describe your post, pick a tone, and we’ll write copy that earns the click past “…more” — plus a connected thread when you generate more than one.
Your captions will appear here.
Generate up to 10 at a time — copy any one with a click.
A free AI social media caption generator that turns a one-line description into ready-to-post captions. Each one is written for the platform you're posting to, in the tone your brand actually sounds like. Updated July 2026
Need a full post, not just a caption? It works for both. Describe the idea and it writes copy that fits the platform.
Built for creators, small business owners, social media managers and agencies who need on-brand copy fast. When you're ready to publish, schedule across every network with Hopper HQ and go from AI caption to posted content in one workflow.
Describe, tone, generate. About ten seconds from a blank field to your first caption.
The more specific the description, the sharper the caption. "Launching our sourdough pizza menu: wood-fired, 48-hour fermented" beats "new menu."
Choose from 10 tones, from professional and casual to witty and inspirational, then pick the network you're posting to and a length: short, medium, or long.
Not feeling the first one? Hit generate again for a completely fresh caption every time. Copy the winner straight to your clipboard.
The same caption rarely lands everywhere. Here's what the generator tunes for on each network, with an example of the shape that works.
Hook in the first line, because the rest hides behind "more." Hashtags on their own line, emoji-friendly.
"Three weeks after we planted the wildflower strip, the bees found it."
More context, fewer hashtags. Room for storytelling and a link back to your site.
"We almost didn't reopen this year. Here's what changed our minds, and what's new."
Short, punchy and trend-aware. The video does the work; the caption sets it up.
"POV: you finally found a pizza worth the queue 🍕"
Professional tone, a clear insight and narrative structure. Lead with the takeaway. For longer posts, try the LinkedIn caption and post generator.
"We rebuilt onboarding around one number. Retention moved 14% in a quarter."
Tight and quotable inside 280 characters. One idea, sharply put.
"Good captions aren't written. They're cut down."
Keyword-rich and descriptive. Pinterest captions double as search text.
"Easy 48-hour sourdough pizza recipe for beginners (no stand mixer)."
Need a channel-specific tool? Try the Instagram Caption Generator or the X Tweet & Thread Generator, or browse hand-curated sets in our Caption Library.
Cross-posting the same photo to Instagram and Facebook? They shouldn't share a caption. Generate a version tuned to each, then schedule them together.
Hopper HQ's Split Captions feature lets you write a separate caption for every network inside a single scheduled post, with no duplicate workflows. Draft both here in seconds, then customize them before scheduling.
Everything you need to go from idea to on-brand caption. Free, and with no account.
Choose from 10 tones, including professional, casual, witty, and inspirational, to match your brand voice without rewriting every draft.
Captions tuned for Instagram, Facebook, LinkedIn, TikTok, X and more, so you're not pasting the same copy everywhere.
Generate up to 10 captions in one go. Ask for more than one and they come back as a connected thread or carousel.
Get a fresh caption instantly if the first one doesn't fit. No limits. Keep going until it's right.
Copy any caption in one tap to paste into any platform or scheduler. Zero friction from idea to post.
Use it as many times as you like without creating an account. It's open to anyone, including teams trialing Hopper HQ.
The generator is a starting point, not a shortcut past the thinking. Use each for what it's good at.
Built for anyone who publishes social content regularly.
Fast first drafts across multiple client accounts.
Post consistently without a dedicated content writer.
Keep your voice consistent across every platform.
Test different caption angles before a campaign launches.
Generate high-volume caption batches for clients.
The generator is a standalone free tool, but it's even more powerful used inside Hopper HQ.
Draft a caption for each platform right here, or inside the Hopper HQ composer with no switching tabs.
Drop it into a visual social media calendar and preview how it'll look before it's live.
Schedule across Instagram, Facebook, TikTok, LinkedIn, Pinterest and YouTube, then track performance in one place.
