Summary

PostMold is a new AI-powered tool designed to help small businesses quickly generate consistent, platform-specific social media posts for X, LinkedIn, Instagram, and Facebook from a single theme or idea. It offers customizable options like tone, emoji usage, and language, and utilizes advanced models (Gemini-1.5-flash and GPT-4o) depending on the plan. This reflects the growing trend of leveraging AI to streamline content creation and enhance social media marketing efficiency for small businesses.

I built PostMold to solve a boring but painful problem: writing consistent, good-looking social posts for small businesses. PostMold lets you: - Generate platform-specific content for X, LinkedIn, Instagram, and Facebook, generated at the same time with single theme/idea - Choose tone, emoji usage, and language (language only in paid plans) - Gives back media suggestion to best match the generated post - Use Gemini-1.5-flash on Free, GPT-4o on Starter/Pro plans - Create and reuse templates (Pro only) There is a free plan (15 posts/month). I would love some feedback on it, perhaps suggestions, or what would make this 11x more useful. Comments URL: https://news.ycombinator.com/item?id=44702616 Points: 1 # Comments: 0
