Your TikTok and Reels cover frame is fighting UI you didn't design for. The caption bar, the like/comment/share icon stack, the profile grid crop — a thumbnail built for horizontal YouTube gets its key details covered or lost the moment it's squeezed into 9:16.
Vertical Video Cover Designer generates cover concepts built natively for vertical video from the first draft. It maps the safe zone around platform UI, checks every concept against a grid-view legibility test (how it reads shrunk to a square in your profile), and gives you composition specs plus a paste-ready AI image prompt for each idea.
Key capabilities:
- 3 cover concepts per video, each respecting TikTok/Reels/Shorts safe zones
- Grid-view legibility test built into every concept — no more covers that only work full-size
- 4 vertical-native archetypes (Center-Face Reaction, Big Word Stack, Split Moment, Object Hero) instead of rotated horizontal templates
- Series-consistency suggestions so a profile grid of your last 9 posts reads as one cohesive show
- Paste-ready prompts for GPT Image 1.5, Gemini 2.5 Flash, or any image generation tool
Perfect for TikTok, Reels, and Shorts creators who are still designing covers in 16:9 and wondering why half the frame gets covered by the Follow button.
Example: Give it your video topic, platform, and whether you're on camera. In one response: 3 covers with exact overlay copy, safe-zone-aware composition, a grid legibility verdict, and an image prompt ready to paste into your generator of choice.
