MUK Flow

MUK Flow is Instagram automation software for Business and Creator accounts, automating direct messages, comment replies, and story interactions using keyword triggers. When a keyword appears in a comment, it sends an automated direct message with links or buttons, ensuring activity even when offline. The platform offers three functions: converting keyword-based comments into direct messages, publicly replying to comments with varied text, and responding to story reactions with personalized messages. Automation can target specific posts, reels, stories, or future content. MUK Flow manages responses through a queue system, retries failed attempts, and tracks activity via a dashboard showing metrics for messages, replies, and interactions. It connects to Instagram Business accounts via official authentication and webhooks. Mobile apps for iOS and Android enable remote access to settings and monitoring. Setup involves registration, Instagram connection, and configuring triggers.
