questions

PostHero is an all-in-one social media management tool that helps you create, schedule, and publish content across multiple platforms including LinkedIn, X (Twitter), Instagram, Facebook, and more. Think of it as your AI-powered social media manager.

ChatGPT is a general-purpose AI assistant, while PostHero is specifically designed for social media success. We've trained our AI on 10,000+ viral posts to understand what makes content perform well on each platform. PostHero helps you create, schedule, and publish - all in one place.

PostHero supports LinkedIn, X (Twitter), Instagram, Threads, Facebook, YouTube, TikTok, and Bluesky. We're constantly adding new platforms based on user feedback, with Pinterest coming soon.

For best results, aim to post once every day on your primary platforms. If that's too much, posting at least 3 times a week is still effective for maintaining a strong presence. PostHero makes this easy with scheduling and content planning features.

PostHero generates content ideas, creates engaging posts optimized for each platform, designs carousels, converts voice notes to posts, and helps you plan your content strategy with AI-powered monthly content plans. You can also schedule and publish directly to all your connected accounts.

Yes! PostHero can schedule and publish content directly to LinkedIn, X, Instagram, Facebook, and other connected platforms. Set your posting times and let PostHero handle the rest.

Unlike generic scheduling tools, PostHero combines AI content creation with multi-platform publishing. Our AI is trained on viral content patterns specific to each platform, helping you create posts that actually perform well - not just generic content.

Absolutely. PostHero supports agentic workflows — you can connect any AI agent (including OpenClaw, custom GPT agents, or your own LLM setup) to our API to fully automate content creation and scheduling. Agents can generate posts, pick optimal times, and publish without any manual input.

OpenClaw is an AI agent framework. PostHero integrates with OpenClaw so you can drop a ready-made social media agent into your workflow — it will research topics, draft platform-optimized posts, and schedule them on your behalf. No coding required to get started.

Yes. PostHero exposes an MCP server, so any MCP-compatible AI host (like Claude Desktop, Cursor, or your own setup) can call PostHero actions directly. This means your AI assistant can schedule and publish posts as a native tool call.

Yes — PostHero works with Zapier, n8n, Make, and similar automation platforms via our REST API and webhooks. Trigger posts from a spreadsheet update, a form submission, a new RSS item, or any other event in your stack.
