Creating Posts
Scroll-stopping social media graphics in under a minute.
Post generation is where Signal really shines. The Creative Director (AI senior art director) plans every design before rendering, so you get cinematic results consistently.
The two types of posts
Photographic posts
Real-looking photography for promotions, lifestyle content, product showcases. Use this when you want the design to look like a magazine ad or campaign shoot.
Typography posts
Bold text-only designs for quotes, announcements, tips, or statements. Use this when the message IS the design.
The form fields
Description (most important)
This is where 80% of the result quality comes from. Treat it like a creative brief:
- Be specific about the subject — "a woman holding coffee" beats "a beautiful scene"
- Mention lighting — "golden hour", "soft window light", "studio lighting"
- Reference real styles — "shot like a Glossier campaign" produces magic
- Describe mood — calm, energetic, luxurious, playful
Bad description: "Post for my spa"
Good description: "A woman with closed eyes wearing a white spa robe, soft natural light, eucalyptus branches nearby, photographed like a luxury skincare campaign"
Composition
- Single Hero — one subject takes the spotlight (best for promotions)
- Text Focus — typography is the design (best for quotes)
- Split — two elements balanced (before/after, product + text)
- Minimal — lots of breathing room, small subject
Post Type
Tells the AI what your goal is: Promotional, Quote, Announcement, Behind-the-scenes, Educational tip, Testimonial, etc.
Text on Image
The headline that appears in the design. Keep it short (3-5 words max). Long text often gets distorted.
After generating
You see your design plus a Crop Preview showing how it'll look on Feed, Stories, Reels, and Ad placements. Use this to spot any text that might get cut off.
You can also:
- Smart Resize — one click to create dedicated versions for every platform
- Add a caption — AI Caption Generator writes Instagram captions with hashtags
- Modify — describe what to change
Pro tip
If you upload a phone mockup or product photo via Hero Image / Mockup, the AI designs AROUND your image as the centerpiece. Perfect for showing off your website, app, or product.
