Simple Post is an AI-native social media scheduler for ChatGPT, Claude, and other AI assistants. Creators and small teams can preview, validate, schedule, and publish platform-specific posts across X, LinkedIn, Instagram, Facebook, Threads, Bluesky, TikTok, YouTube, Pinterest, and Telegram. It works through secure remote MCP as well as a web app, CLI, and API, and validates platform limits, required fields, media, and formatting before publishing. The core is open source under the MIT License, and every hosted plan starts with a 7-day full-feature trial with no credit card required.
