Step-by-Step Setup 👋
1. Open YouTube Studio
- Go to studio.youtube.com and sign in.
- If you’re like me, you’ll probably have three tabs open already—close the extras.
2. Upload or Select Your Video
- Click “Content” on the left.
- Choose the video you want captions for (mine was a product demo—lost my manual transcript once after a crash).
3. Go to Subtitles Tab
- Hit “Subtitles” in the video menu.
- Wait—don’t panic if it takes a sec to load. Patience.
4. Use the AI Subtitle Generator
- Click “Add Language” and pick English.
- Under “Automatic,” select the AI option (powered by Gemini/YouTube’s AI).
- The auto-generated captions will appear in minutes.
5. Edit and Fine-Tune
- Play the video and fix timing or spelling.
- Note: if you enabled Google sync, most changes auto-save—still, manual tweak feels safer.
6. Download or Publish
- Hit “Publish” to make captions live.
- Or click the three dots, choose “Download .srt” if you want a backup copy.

Quick Comparison of Captioning Methods
- Manual vs AI: Manual is error-prone and slow—AI is instant but needs a quick proofread.
- Free Tools vs Paid: Google’s built-in is free; Filmora’s AI subtitle generator saves time and handles batch edits.
- Auto vs Human: Auto gives you a solid draft—human tweak ensures accuracy, especially for jargon.
