Noolu is an Instagram engagement automation platform designed to help creators and businesses respond to audience interactions and turn followers into customers. Using keyword triggers, it detects specified words in comments on Instagram Reels and automatically sends relevant links, prices, or location details through direct messages. The service centers on a visual, no-code flow builder, allowing users to create conversational automation paths and add custom delays for multi-step messages.

Noolu connects through Instagram’s official Graph API and Instagram Login for Business, using OAuth tokens rather than asking users to share their passwords. The company describes its design as policy-conscious, following Meta’s messaging windows and API rate limits. For new users, Noolu provides a visual setup guide with screenshots to help connect an Instagram account. The platform offers a free plan, with pricing information and product resources available on its website. Noolu is presented as a way to maintain prompt, automated engagement around the clock, including comment-triggered replies, without manually handling every interaction.
