# Mastak > AI comment-to-DM automation for Instagram and Telegram — turns every comment into a qualified sales conversation, hands-free. Mastak is a cloud SaaS that watches your Instagram posts and Telegram channels, fires a personalised DM the moment someone comments, and then runs a full AI sales pipeline in the chat: qualify → value → handle objections → close → hand off to a human when the deal is warm. No flow-builder. Three questions at setup. Real LLM choice (GPT-4o mini default, Gemini, Claude BYOK) via OpenRouter. Flat-rate billing — pay per account, not per contact. Built for coaches, course creators, influencers, and agencies that sell through DMs and are tired of paying per-message fees or babysitting keyword scripts. ## Key pages - [Home](https://mastak.app/): What Mastak does and how to start - [Blog](https://mastak.app/blog): Guides on Instagram DM automation, comment-to-DM setup, AI sales pipelines - [Sitemap](https://mastak.app/sitemap.xml) ## Pricing - FREE: $0 — rule-based replies, no AI (free forever), "powered by @mastak.app" signature - START: $12/mo — 1,000 AI conversations/month (GPT-4o mini) - PRO: $24/mo — 3,000 AI conversations/month, choose your LLM + BYOK Claude - AGENCY: $59/mo — 10,000 AI conversations/month, BYOK Sonnet/Opus + white-label - Trial: 14-day AI trial, no credit card required — up to 300 fast AI conversations (GPT-4o mini); after the trial, upgrade to Pro $24/mo when you're ready ## Contact hello@mastak.app
