What does fframes do?
fframes is a web-based tool that automatically adds captions or subtitles to your videos. You upload a video file, and the tool uses AI to transcribe the spoken audio. It then translates that text if needed and burns the subtitles directly onto the video. The entire process happens in your web browser, which means your video data is not sent to any external server. This makes it a fast and private option for adding text to videos. The tool is designed for simplicity. There are no complex settings or options to configure. You get a finished video file with the subtitles embedded, ready to download and share. It uses artificial intelligence for the speech-to-text conversion, which is the core of its functionality. This makes it particularly useful for creators who need to add accurate captions quickly. fframes is ideal for content creators who post videos on platforms like YouTube, TikTok, or Instagram, where captions improve accessibility and viewer engagement. It is also helpful for educators creating online courses or for anyone producing content for an international audience that requires translation. The fact that it is free and requires no account lowers the barrier for anyone to start making their videos more accessible immediately.
