AI Caption Generator for Reels
SocialGrovv's AI Caption Generator transcribes your video or voiceover, then styles the captions — word-by-word, karaoke pop, or classic — with your brand fonts and colors. Captions are safe-zone aware for Reels, TikTok, and Shorts, and you can publish or schedule the final video without switching apps.
How it works
Step 1
Drop a video or voiceover
Upload a Reel, TikTok, or Short, or use a voiceover generated inside SocialGrovv. Transcription runs automatically.
Step 2
Pick a caption style
Choose word-by-word, karaoke pop, classic block, or a custom style. Every style respects the safe zones of Reels, TikTok, and Shorts.
Step 3
Style with your brand kit
Fonts, colors, outlines, and highlight colors pull from the brand kit so every caption feels part of the same channel.
Step 4
Publish or schedule
Send the captioned video to Instagram, TikTok, YouTube, or Facebook — instantly or via the AI content calendar.
Retention-first captions
Word-by-word timing keeps eyes on the screen through the first three seconds — the make-or-break window for Reels and Shorts.
Accurate transcription
SocialGrovv's transcription handles accents, technical terms, and product names cleanly, so you spend seconds correcting, not minutes.
Safe-zone aware
Captions sit outside the like button, description, and platform UI so nothing gets clipped by the Reels or TikTok interface.

Frequently asked questions
Do the captions work in languages other than English?
Yes. SocialGrovv supports major European, Asian, and Latin-American languages for transcription and styling. Accuracy is highest when the source audio is clean and single-speaker.
Can I keep the captions when cross-posting?
Yes. Captions burn into the video during render, so wherever you publish — Instagram, TikTok, YouTube, Facebook — they travel with the clip.
Can I edit specific words?
Yes. Every caption is editable in the timeline. You can fix a misheard name, tighten a line, or change a highlight color on a single word without re-transcribing.
Is this bundled with the video plans?
Yes. Caption generation is included on Starter, Pro, and Elite. There is no separate caption add-on to buy.
