The first line does the work
Instagram shows the start of a caption and hides the rest behind "more". The draft puts the point in the first line for that reason. If the first line alone would not make you tap, rewrite it.

Getting a good result
Hashtags that match the video
Instagram allows up to 30 hashtags; this tool writes three to five, and only for subjects in your transcript. A few accurate tags tell the platform who the Reel is for. A wall of loosely related ones does not.
00:40Questions
Instagram Reels caption generator: common questions
How long can a Reels caption be?
2,200 characters, including hashtags. Most captions that get read are a fraction of that.
Should hashtags go in the caption or the first comment?
Either counts toward the limit of 30. In the caption they are there from the moment the Reel is posted.
Does it write the words that appear on the video?
No, only the caption under the Reel. For words on the video itself, use add subtitles to video or add text to video.
