How to Add Captions to a Screen Recording

Generate accurate subtitles for your screen recording using AI transcription. Captions improve accessibility, boost engagement on social media (where 80% watch on mute), and make your content searchable by keyword.

Step-by-step

  1. 1

    Record your screen with mic audio enabled

    AI captions are generated from audio, so your recording needs a voice track. Enable your mic before recording and speak clearly.

  2. 2

    Open the recording in Screenify editor

    After recording, the editor opens automatically. Your recording appears on the timeline with the audio waveform visible.

  3. 3

    Click 'Generate Captions'

    Hit the captions button in the toolbar. Screenify transcribes your audio on-device using the Neural Engine — no upload to a cloud service. Processing takes about 10 seconds per minute of recording.

  4. 4

    Review and edit the transcript

    The generated captions appear word-by-word synced to your audio. Click any word to correct it. Pay special attention to technical terms, product names, and acronyms that AI may misspell.

  5. 5

    Choose caption style and export

    Select a caption style (size, position, highlight color). Captions are burned into the exported video so they appear on any platform — LinkedIn, YouTube, Slack, or embedded on a webpage.

Screenify features that help

AI Captions

On-device transcription powered by Apple's Neural Engine. No internet required, no audio sent to the cloud, and it supports 50+ languages.

AI Translation

After generating captions in your original language, translate them into any of 50+ languages with one click. The translations stay synced to the original timing.

Pro tips

Speak at a steady pace with clear enunciation. The AI handles accents well, but mumbling or talking too fast reduces accuracy.

Correct technical jargon immediately after generation — domain-specific terms are where AI makes the most mistakes.

For social media posts, use large, center-bottom captions with a highlight color. Viewers scrolling on mobile need captions to be prominent.

Generate captions before trimming your recording. The full audio context improves transcription accuracy compared to processing chopped-up clips.
