PostJay

PostJay is a SaaS social media scheduling tool that allows users to write a single post and distribute it across 18 platforms, including Instagram, X (Twitter), Facebook, LinkedIn, TikTok, YouTube, Pinterest, Bluesky, Threads, Mastodon, Discord, Telegram, and Tumblr. It automatically adjusts each platform's character limits, aspect ratios, hashtags, and threading, with live per-platform previews before publishing. PostJay integrates with AI assistants through the Model Context Protocol (MCP), enabling ChatGPT, Claude, Cursor, or custom scripts to schedule and publish posts using natural language commands. It also offers a REST API for programmatic access. AI-generated captions, hashtags, and hooks are available to assist content creation. The platform provides a visual content calendar with month, week, and day views, bulk scheduling, client approval workflows using magic links and audit trails, and cross-platform analytics for impressions, engagement, and top-performing posts. It is aimed at solo creators, teams, and agencies, with tiered pricing and a free trial.
