FAQ
What’s the best Instagram caption length?
80–250 characters works best for feed posts. Reels cap around 100 characters. Carousels can run 500–700 — readers actually swipe and read longer copy there.
Is this AI or template-based?
Templates with your inputs slotted in. The full AI captions engine — trained on YOUR voice — lives inside WowPostio AI after sign-up. Free plan available.
Can I generate more than 5?
Yes — change the format, emotion or CTA and hit Generate again. Each combo produces a fresh set of 5 captions.
Which CTA converts best?
One verb plus one action. "Book now", "DM us", "Link in bio", "Tap to save". Avoid stacking choices — single action wins.
