FAQ
How does the caption generator work?
Describe what's in your photo or video, pick a mood (happy, excited, thoughtful, nostalgic, motivational, funny, cozy, or adventurous), choose a caption length (short/medium/long), and select a platform (Instagram, TikTok, Facebook, or Pinterest). The tool composes a caption from a 70+ template library (mood × length combinations) with a hook, supporting body, platform-specific CTA, mood-aware emojis, and 5-15 keyword-based hashtags.
How many caption templates are included?
70+ templates organized by 8 moods × 3 lengths. Each combination has multiple template variations, and each generation produces 3 distinct variations per request — so you can pick the one that fits your post best.
Which platforms are supported?
Four platforms: Instagram (2200 chars max, 125 above-fold optimal, 'link in bio' CTA, 15 hashtags), TikTok (2200 chars max, 'follow for more' CTA, 5 hashtags), Facebook (63206 chars max, 'comment below' CTA, 3 hashtags), and Pinterest (500 chars max, 'tap to save' CTA, 4 hashtags). Each platform has its own char-limit validator and CTA.
What is the first-comment hashtag separator?
For Instagram, you can choose to put all hashtags in the first comment instead of the caption itself — this keeps your caption clean and is a popular growth tactic. The tool splits the caption from the hashtag block and shows both separately for easy copy-paste.
