XCaptions from the video itself
Not a title prompt, not a topic guess. The tool reads what your video actually says and shows.
STEP 01
Upload your video
MP4 or MOV, up to 170 MB. It uploads to secure storage and is deleted the moment your captions are ready.
STEP 02
It watches the video
We transcribe the audio and read a few key frames, so the caption is grounded in the real hook, message and moment.
STEP 03
Get four clean options
Distinct angles, each ready to paste. Copy the one that lands, or ask for a fresh set. No hashtag spam, just the copy.
LinkedIn caption generator FAQ
Is the LinkedIn caption generator free?
Yes. You can caption up to five videos a day with no account and no card. Inside Cadenus there is no daily limit, and captions come in your brand's voice for every client.
How does it write a LinkedIn caption from my video?
It transcribes the audio and looks at a few frames, then writes a professional, value-first caption grounded in the real point of the video, the way strong LinkedIn posts read.
What makes a good LinkedIn caption?
A clear opening line, a genuine insight or takeaway, short readable lines, and a soft prompt to engage. No emoji spam. The tool gives you a few angles so you can pick the one that fits.
Do you store my video?
No. The video is processed once to write your captions, then deleted straight away. Nothing about it is kept.
Where are the hashtags?
We keep the caption itself clean, a wall of hashtags in the copy reads as spam, so hashtags are handled separately, the way strong accounts post. If you want a smart, sized set for this post, use our free hashtag generator. Open the hashtag generator.
This is one small thing Cadenus does
Inside the product, captions come in your brand's voice for every client, then run through production, client approval and native publishing, all in one place.
