Frequently asked questions
How does the caption generator work?
It combines proven caption structures — a hook, a short body and a call to action — written for the tone and goal you choose, then adds emoji and hashtags that match your topic. Generate as many sets as you like.
Can I edit the captions?
Yes — every caption is editable, shows its character count against the platform limit, and can be previewed on a mock post.
Which call to action should I use?
Use “Comments & engagement” to grow reach, “Sales” for products, “Link clicks” to send people to your site and “Follows & saves” to grow your audience.
Is my topic sent anywhere?
No. The captions are generated in your browser from built-in templates, so nothing you type leaves your device.
How long should a caption be?
One or two lines work well for quick posts; longer, story-style captions suit Instagram and LinkedIn. Put the hook in the first line, because feeds cut long captions off.
