An AI LinkedIn caption generator that sounds like you.
Captiv is an AI LinkedIn caption generator: you upload a finished image, carousel, or video, and it writes three ready-to-post captions — a hook angle, a story angle, and a value angle — each with a tuned set of hashtags and a one-line why, in about ten seconds, tuned to how LinkedIn works.
Captions are how LinkedIn finds your post.
The words you write are searchable. LinkedIn Search covers posts alongside people, jobs, and companies, and members can search using keywords or natural, conversational language — so the language in your caption is what people actually query.
And your caption is read by the feed, not just people. LinkedIn’s AI systems weigh hundreds of signals to decide what appears in each member’s feed, including the context of your post — what it’s about and whether it provides knowledge or advice. Clear, specific captions give that system something to understand.
Three steps. About ten seconds.
No prompt-wrangling — Captiv works from the post you already made.

How does the LinkedIn caption generator work?
Upload a finished post — an image, carousel, or video. Captiv’s AI looks at what’s actually in it, then writes three caption options with hashtags and a one-line why, tuned for LinkedIn, in about ten seconds.
How many hashtags should a LinkedIn post have?
Captiv adds a tuned set per option. LinkedIn treats hashtags as topic tags that organize and surface content, not as a reach multiplier — so Captiv keeps them relevant to your post instead of stuffing them in.
Can it write posts in my own voice?
On paid plans, yes. Captiv learns your voice from the posts you keep and edit so captions sound like you. The free plan uses a clean, LinkedIn-native voice.
What formats does it support?
Single images, carousels, and video posts. Video and carousel analysis are on Pro and Studio; the free plan covers single images.
