Blooio↗
Blooio provides a REST API specifically for iMessage, enabling developers to build custom AI agents with native iMessage features like read receipts and typing indicators.
Similar to Chert, Blooio directly targets iMessage AI deployment and emphasizes developer-friendly API access for building AI bots. It focuses on providing the underlying API for integration rather than a full platform.
2
OpenClaw is an open-source, self-hosted AI assistant that integrates with iMessage (and other platforms) via a command-line tool, offering high customization and control over the AI's operation.
Like Chert, OpenClaw enables AI on iMessage, but it is a self-hosted, open-source solution, appealing to developers who prefer more control over their infrastructure, unlike Chert which appears to be a managed platform.
3
Flux allows users to quickly create and deploy AI agents directly within iMessage, focusing on natural, native messaging interaction without requiring an app download for the end-user.
Flux is a very direct competitor, offering a similar 'AI on iMessage' solution with a strong emphasis on rapid deployment and a native user experience, much like Chert's value proposition.
4
Mei↗
Mei offers a self-service custom AI builder for deploying AI agents across various messaging channels, including SMS, phone calls, and messenger apps, with a focus on emotionally intelligent AI.
