Postmint
Postmint is a SaaS tool that enables users to create on-brand social media graphics instantly from a simple text description. Users save their brand kit—colors, fonts, and logo—once, and then every post automatically adheres to these brand guidelines. No design skills are required; the platform handles layout, typography, and spacing behind the scenes. The workflow is straightforward: write a sentence describing the post (e.g., a launch announcement, a sale, or a tip), and Postmint generates a polished PNG image complete with a caption. The tool uses hand-crafted templates to ensure consistent, professional-looking results, avoiding the randomness of fully AI-generated designs. Postmint supports multiple social media formats, including square for Instagram feed, tall for Stories, and wide for LinkedIn. Users can further refine any post by chatting with the editor—instructions like "make it shorter" or "bolder headline" are applied instantly, without touching design controls. A free plan offers 10 posts per month with no credit card required, while paid plans scale up to 150 posts per month. Built by a solo founder frustrated with the time and effort required for on-brand posting, Postmint targets solopreneurs, content creators, and small businesses who need to maintain a professional social media presence without design overhead or hiring help.
