Overview
Postmine is a Chrome extension that lets you capture trending posts from LinkedIn, Reddit, Facebook, and X with one click. Its AI then transforms each post into seven platform-ready content pieces (blog, LinkedIn, Twitter thread, Facebook, Instagram, Reddit, FAQ). It includes brand voice profiles, a content calendar, bulk capture mode, and AI reply suggestions. Pricing starts at $49/month with a $1 trial and a $10 10-day pass.
Google Workspace Studio is a no-code platform for building AI agents inside Gmail, Docs, Sheets, and other Workspace apps. Powered by Gemini 3, it turns natural language prompts into workflows that can triage emails, generate reports, or coordinate projects. It is designed for teams and brings agentic automation to everyday office work. Pricing is not publicly detailed but likely requires a Google Workspace subscription.
