How to use the caption generator
Tell it what you sell and who it is for, pick a tone, and it writes four Instagram captions from different angles: a short hook, a product story, a benefit and a question for comments. It works from the facts you give it and is told not to invent prices, reviews or health claims. Copy the one you like, check it, edit it and post.
- 1
Describe the product
Write one to three sentences about what you sell: what it is, what it is made of or how it is used, and anything that makes it yours. Add who it is for if you know.
- 2
Pick a tone
Choose the voice your brand already uses. Turn emoji and hashtags on or off to match how you post.
- 3
Copy, edit and post
Read the four options, copy the closest one and change anything that does not sound like you. Check every fact before you post.
Get better captions
- Name the product and one concrete detail, such as a scent, material, flavour or size.
- Say who it is for: “busy parents”, “home bakers”, “people who hike”.
- Mention what is true right now, such as a restock or a new colour, only if it is real.
- Put prices and offers in your description only if you want them used; the tool is told not to make them up.

Questions about the caption generator
Is the Instagram caption generator free?
Yes. Your first set of captions needs nothing at all. To keep generating after that, enter your email once. There is no account or card.
What should I type to get good captions?
One to three sentences about the product: what it is, one concrete detail and who it is for. Specific descriptions get specific captions; a vague description gets general ones.
Will it make things up about my product?
It is told to use only the facts you give it and never to invent prices, discounts, reviews, awards or statistics. AI can still get things wrong, so read each caption and check the facts before you post.
Can I use it for skincare, food or supplements?
Yes. For beauty, food, drink and supplement products it is told to avoid medical and health claims and describes taste, texture, feel or ritual instead. Rules differ by country, so check any claim against the rules where you sell.
Do you keep what I type?
Youanai does not save your description or the captions. They are sent to our AI provider to write the captions. To limit use, we keep an anonymous browser cookie and short-lived counters. If you enter your email, we add it to the Youanai email list for marketing tips and product news, and you can unsubscribe at any time.
