Free AI Instagram Caption Generator

Write captions from the photo description you supply. The tool does not see your image. It drafts three numbered options, each under 40 words.

How it works

  1. Describe the photo in plain words: what is visible, what happened, and any facts you want included.
  2. Pick a tone: Plain or Friendly.
  3. Review the three numbered caption options. Each stays under 40 words and avoids hashtags, emojis and sales calls you did not supply.

Tips for better results

  • State only what the photo shows. If you can see three notebooks but not their price, leave price out so the caption does not suggest a sale.
  • Say what is missing when it matters. If the chair repair is untested, note that so the draft does not imply the chair is safe to use.
  • Name the context, not the emotion. Write that this is a community club rather than telling the tool to sound heartwarming.
  • Read each option beside the photo description. Cut any claim that is not supported, and choose the option that fits your own voice.

Review every draft first. The tool does not verify facts or safety claims and cannot check prices, availability or permissions. You are responsible for what you post.
