Instagram Reels AI Generator
SocialGrovv's Instagram Reels Generator writes the hook, script, voiceover, and captions into a brand-kit 9:16 Reel. For autonomous channel growth, Reels are planned in Plan Builder, produced here, then the system posts to your connected Instagram account on schedule — and can mirror the same Reel to TikTok, YouTube Shorts, and Facebook without re-editing.

How it works
Step 1
Choose a Reels angle
Pick a niche or paste a topic — SocialGrovv proposes three hooks and a 30–60 second script tuned to Instagram's retention curve.
Step 2
Apply the brand kit
Lock in fonts, colors, logo overlay, and outro card. Every Reel in the queue keeps the same feed-consistent look.
Step 3
Render and preview
SocialGrovv assembles B-roll or AI images, aligns bold captions to the voiceover, and gives you a preview inside a phone-frame mockup.
Step 4
Schedule to Instagram
Send the Reel into the content plan calendar with caption and cover — after approval, the system posts to your connected Instagram account when the slot hits.
Feed-friendly, brand-consistent Reels
Brand kits keep every Reel looking like it belongs on the same profile — fonts, palette, logo, and outro card are re-used across the queue.
Retention-oriented scripting
Scripts open with a hook, land the key idea within the first sentence, and set up a clear payoff so viewers keep watching to the end.
Cross-post without extra work
The same Reel can be routed to TikTok, YouTube Shorts, and Facebook Reels — one export, four surfaces.

Frequently asked questions
Does SocialGrovv post Reels directly through Instagram?
Yes. When you connect your Instagram Business or Creator account, SocialGrovv uses the official Instagram Graph API to publish Reels with caption, cover, and location.
Can I collaborate on Reels drafts with a teammate?
Elite plans include multi-seat access. Teammates can review scripts, tweak captions, and approve Reels before they hit the calendar.
What Reel length works best?
SocialGrovv defaults to 30–60 second Reels because they consistently retain attention. You can generate 15-second cuts for punchier hooks or up to 90 seconds for tutorials.
Can I use my own footage inside a generated Reel?
Yes. Upload clips into the media library and drag them into any scene of a generated Reel — brand kits, captions, and voiceover continue to apply.
