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.

Studio-quality podcast and video recording, editing, and publishing in your browser
Every participant records locally on their own device, capturing up to 4K video and 48kHz uncompressed audio in separate tracks that stay sharp regardless of connection quality.
Edit video by editing the transcript — search, cut, copy, and paste words and the footage updates. AI then removes filler words and silences or fixes eye contact in one click.
Turn a finished session into promotional assets: short clips optimized for each platform, thumbnails, headlines, show notes, transcripts, and translations or dubs in over 30 languages.
Broadcast in full HD 1080p to unlimited destinations simultaneously, or host webinars with registration, branded emails, Q&A, live call-ins, polls, and HubSpot lead capture.
