dsign.so

dsign.so makes on-brand social posts for people who aren't designers and mostly work on their phones. Set up your brand once (logo, colours, fonts and the way you talk), then type what your post is about. Every template in the library fills with your words, in your brand, at once. Pick the one you like, adjust anything on it, and export as PNG, JPG or video. 1,200+ designer-reviewed templates in every size, carousels in one go, your own photos and background removal. Free to start; Pro adds unlimited posts, five brands and HD exports.
