How to Get the Most Engagement from Your Generated Captions

1. Nail the 125-Character Hook

Instagram and TikTok truncate captions with a "...more" link after 125 characters. Make sure the first line poses an urgent question or provocative statement.

2. Use Vertical White Space

Dense walls of text fatigue mobile users. We automatically format our templates with generous line breaks and bullet points to double reader dwell time.

3. Prioritize Saves and DM Shares

Likes are vanity metrics in 2026. A user saving your post to an Instagram collection or forwarding it to a group chat triggers the highest recommendation weight in the algorithm.
