AI captions, animated emojis and multi-platform resizing in seconds
Uploads are transcribed automatically in 100+ languages, making the tool usable for non-English and multilingual creators.
Word-by-word animations, emphasis and emoji can be applied from presets, then fully customised for fonts, colours, size and position.
Fix words and adjust caption timing on a simple timeline instead of re-recording or exporting to a separate editor.
Reformat a single captioned project for TikTok, Reels, Shorts and LinkedIn aspect ratios without manual reframing.

Free AI captions for every image you post
Upload a photo and let the AI read its content and produce caption text that fits the picture rather than generic filler.
Generate captions in over twenty languages, including English, Spanish, Portuguese, German, French, Chinese, Japanese, Korean, Arabic, Hindi, and Vietnamese.
Choose the target network, such as Instagram or Facebook, so tone and formatting match where the post will appear.
Generated captions can be copied immediately and pasted into the social app of your choice.
