Auto Captions: Video Subtitles

Auto Captions helps you add automatic subtitles to videos directly on your device.

Choose a video, generate timed captions, customize their appearance, correct the text, and export a finished video ready for TikTok, Reels, Shorts, YouTube, and other platforms.

No account. No video upload. No watermark.

AUTOMATIC VIDEO CAPTIONS

Turn speech into word-by-word timed captions in seconds. Transcription is processed locally on your device, so your video does not need to be uploaded to a server.

Your videos remain on your device during transcription and editing. Nothing is uploaded as part of the caption-generation process.

• Karaoke highlight
• Bold outline
