Write hook-first LinkedIn captions from a single topic

It is a free tool that turns a short topic into ready-to-post LinkedIn captions. You describe what the post is about, optionally add a tone and a few keywords, and the AI writes hook-first captions you can copy straight into LinkedIn.

Lead with a hook that earns the click on "see more," keep the lines short and scannable, and end with a clear point or question. Feed that same topic and angle into the generator and it drafts captions in that rhythm for you.

There is no single right length. Short captions of a line or two work for quick takes, while 900 to 1,300 characters suit a story or a how-to. The tool shows a character count on each result so you can match the length to the post.

A LinkedIn post allows up to 3,000 characters. Only the first roughly 140 characters show before the "see more" cutoff on the feed, so the opening line matters most. Every caption stays well under the 3,000 limit.

Yes. The tone field is optional, but adding something like "direct," "story-led," or "contrarian" steers the voice of every caption. Leave it blank and the generator picks a neutral professional tone that fits LinkedIn.

Yes. The captions are a starting draft, not a locked output. Copy any result, paste it into LinkedIn or a doc, and rewrite the parts that do not sound like you before you publish.

Each run returns a set of five caption options from one topic, so you can compare angles and pick the strongest. Every item carries its own character count.

Yes, it is free to use. Describe a topic, generate captions, and copy the ones you want. There is no sign-up wall in front of the generator.

This tool is tuned for LinkedIn's professional rhythm. For other platforms, use the Instagram Caption Generator or the TikTok Caption Generator, which match each platform's length and voice.
