# 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://dreybuilds.com/): What Mastak does and how to start - [Blog](https://dreybuilds.com/blog): Guides on Instagram DM automation, comment-to-DM setup, AI sales pipelines - [Sitemap](https://dreybuilds.com/sitemap.xml) ## Pricing - Free plan: 200 conversations/month, 14-day AI trial - Starter ($12/mo): 300 conversations, GPT-4o mini - Pro ($24/mo): 1000 conversations, choose your LLM - Agency ($59/mo): 4000 conversations, BYOK Claude/Sonnet ## Contact hello@mastak.app
