How does Iconosquare’s Instagram caption generator work ?

Step 1: Select your language

Select your preferred language from the dropdown. Our AI tool speaks several languages! It can generate captions in English, French, Spanish or German.

Step 2: Select your tone of voice

Carefully select the tone that aligns with your brand's personality. Is it fun and friendly? Serious and directive? Convincing? Maybe Empathetic? The tone you set will deeply influence audience engagement.

Choose wisely and the AI writing will stick to it. Thanks to this feature, you can maintain a consistent tone, style, and messaging across all your posts, reinforcing your brand identity.

Step 3: Select the caption length

Whether you prefer short, snackable captions or longer literary posts, the choice is yours. The content generated can be up to 800 characters. 

At this step, you can choose to include hashtags and/or include emojis. Artificial intelligence will place them in the right place for you. Simply activate or deactivate the options to suit your needs.

Step 4: Add a description in few words

To create a caption that matches your Instagram photo or video, give a short description that provides context. Just a few words are enough! But the more detailed your brief is, the more relevant the caption will be.

Step 5: Add keywords

Keywords act like hashtags. It is a list of words to help the AI create THE caption for you depending on the context. Add as many keywords as you want, separated by commas.

Step 6: Let the magic happen

Click on the “Make some magic” button and voilà. The generated caption will appear. You have the possibility to generate more engaging ideas from it to have several propositions by clicking on “Generate more ideas”.
