Frequently asked questions
What is the ideal caption length?
For TikTok and Instagram, 2-4 sentences (50-150 characters) is ideal. The first 2 lines are visible without tapping 'more.' For X, keep it under 280 characters. For LinkedIn, longer posts (150-300 words) can perform well.
How many emojis should I use?
2-5 emojis per caption is the sweet spot. Emojis break up text and add visual appeal, but more than 10 can look spammy and reduce readability. Use relevant emojis, not random ones.
Does the tool check my caption for grammar?
The tool checks length, character limits, emoji count, hashtag count, CTA presence, question presence, and hook strength. It does not check grammar — use a tool like Grammarly for that. The focus is on social-media-specific optimization.
