Frequently asked questions

How do I generate a social media caption?
Enter your topic, optionally add a key message or angle, select your platform and tone, choose whether to include hashtags, and click Generate. You get 3 caption variations — each with a hook, body, and call-to-action — that you can copy and post directly.
What makes a good Instagram caption?
A strong Instagram caption starts with a hook in the first 1-2 lines (since the rest is hidden behind 'more'), delivers value or emotion in the body, and ends with a clear call-to-action. Instagram shows the first 125 characters before truncating, so lead with your most compelling sentence.
How long should a LinkedIn post caption be?
LinkedIn posts perform best at 1,300–2,000 characters (around 200–300 words). LinkedIn shows the first 210 characters before 'see more', so your opening line should create curiosity. Professional, first-person storytelling earns the highest engagement on LinkedIn.
How many hashtags should I use?
Instagram: 5–10 targeted hashtags. LinkedIn: 3–5 professional hashtags. TikTok: 3–5 including #fyp. Twitter/X: 1–2 only. Using too many hashtags makes posts look spammy and can reduce reach. Relevance beats quantity.
Should I personalise the generated captions?
Yes. The generator creates the structure — hook, body, and CTA — based on your topic and tone. For best results, add specific details: real numbers, personal anecdotes, product names, or concrete examples. The more specific your caption, the more authentic it feels and the more engagement it earns.
