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.
Speak and get perfectly formatted text in any Mac app
Trigger transcription from anywhere on your Mac with Command+Option+V and paste the result into whatever app has focus.
Simple, Email, Note, Message, and custom modes shape the output into punctuation-correct prose, structured emails, bullets, or casual chat text.
Add industry jargon, acronyms, and names so specialist terms are spelled and capitalized the way you expect.
Buy once and bring your own OpenAI key instead of paying a recurring subscription fee.
