Free Social Media Caption Generator

Staring at a blank caption box? Use WordMitr’s free AI-powered caption generator to create ready-to-post captions for Instagram, Facebook, X (Twitter), LinkedIn and more — in seconds, not hours.

Pick your platform, choose the type of content you’re posting, select a tone and (optionally) describe your photo or video. We’ll suggest multiple caption ideas you can tweak, save and reuse.

Save time, stay consistent and keep your social feeds active — even on busy days.

Tip: The more specific your description, the more personalised your caption ideas will be.

We lightly adapt wording and style based on the platform you choose.

Helps the tool suggest captions that match the kind of photo or video you’re posting.

Choose how you want your caption to sound — you can always tweak it after.

Add a few details about the mood, location, occasion or what you want followers to feel.

How to use this caption generator effectively

  1. Choose your platform so the tone and style feel natural for Instagram, Facebook, X or LinkedIn.
  2. Select your content type and tone so the tool knows whether this is a fun selfie, a quote post, a travel update, or something else.
  3. Briefly describe your post — where you are, what’s happening, or what you want followers to do.
  4. Generate captions and scroll through the ideas. Mix, match and edit until it sounds like you.
  5. Copy and paste the caption into your social app, add hashtags or emojis if you like, and you’re done.

Use the tool as a starting point, not a final script. Adding a personal detail, inside joke or brand phrase on top of the AI suggestion is what makes your caption feel genuinely “you”.
