Frequently asked questions
How does the AI social media post generator work?+
You give Marketly your website URL. The AI analyses your brand, tone and offers, then generates ready-to-post captions and visuals for Instagram, Facebook, LinkedIn and X.
Can it write in my brand voice?+
Yes. Marketly reads the copy on your website to learn your tone, then applies it consistently across every post — so it sounds like you, not like generic AI.
Do I get images too, or just captions?+
Both. Marketly picks the best imagery from your website and pairs it with each caption, so every post is publish-ready — no design work required.
Which platforms are supported?+
Instagram, Facebook, LinkedIn and X (Twitter). Posts are automatically formatted with the right character counts, hashtags and aspect ratios for each platform.
How many posts can I generate?+
You can preview posts for free without signing up. A Marketly Pro subscription unlocks unlimited AI social media post generation, scheduling and downloads.
