Meet your customers on every channel, and handle their requests and complaints in one place.

Complaintr Core answers your customers on your website and social media accounts, and passes what it cannot solve to your team.

Start freeExplore demo

On a hotel's website, a guest asks the widget about transfers and breakfast, or opens the hotel's news; on Instagram, Core answers a boutique customer's size question and opens an exchange ticket, and on WhatsApp it answers a balloon tour question and passes a date change to the team.

Wherever customers write, they get an answer there.

Your website, Instagram, WhatsApp, and more. One assistant, one inbox.

Automatic assignment

Every complaint and piece of feedback goes to the right unit or person on its own.

Slack, Jira, and Linear

Each complaint opens as a message, ticket, or issue where your team already works.

Weekly summary

Core reads the week's complaints and tells you what changed.

Surveys

Core asks the customers who stay quiet, as a short chat.

Built for developers, a few lines are enough.

Add the widget with one tag, run Complaintr from Claude, Claude Code, or Codex, and turn complaints into GitHub issues.
