Hay is an AI customer service automation platform that is source-available, utilizing the Model Context Protocol (MCP) to seamlessly integrate AI-driven reasoning with actionable business processes, such as managing refunds through Shopify, generating tickets in Zendesk, and updating HubSpot records, among 174 other actions across 9 distinct integrations. Its architecture distinctly separates the reasoning component of AI from the execution of actions, incorporating confidence scoring and a two-step validation process for any destructive operations, while allowing users to configure playbooks using plain language instead of complex flow builders. The platform is governed by the Hay Community Licence v1.0, which, while source-available, does not qualify as OSI-approved open source; it allows for inspection, modification, and self-hosted deployment, but prohibits operating Hay as a competing hosted service, ensuring the integrity of its ecosystem. Full source code is available for audit purposes, enhancing transparency and trust. The platform is hosted in the EU, specifically on DigitalOcean servers located in Ireland and Amsterdam, with an option for self-hosting as well. It supports various communication channels, including WhatsApp, Instagram, web chat, and email, and operates in multiple languages to cater to a diverse clientele. Pricing is bundled starting from €50 per month, which includes resolutions without additional charges per resolution, making it an economical choice for businesses looking to streamline their customer service operations. Additionally, Hay's user-friendly approach and extensive integration capabilities make it an attractive solution for companies aiming to enhance their customer engagement through automation.
