FlowDown is a native AI chat client for Apple platforms, designed for speed, privacy, and power users. It provides a fluid, responsive interface to interact with a variety of AI models, right from your iPhone, iPad, and Mac.

About Pricing Update

FlowDown is scheduled to become free next year. With growing community support and feature maturity, maintenance costs have decreased, allowing us to operate more efficiently. Before this transition, prices will be reduced in phases. All core chat features will remain free, with subscription fees applying only to future personalization options.

Note: FlowDown is a Zero Data Retention (ZDR) app. While the app collects no data, our website uses anonymous analytics and Cloudflare security protection to maintain service quality.

FlowDown is designed for users who want full control over their AI models and are willing to configure them manually.

Every model behaves differently based on its capabilities, deployment method, and hardware resources. You are responsible for configuring and testing each model you use. FlowDown provides the tools and interfaces—you provide the configurations.

For bulk management, FlowDown supports importing and exporting model configurations (.fdmodel files). You can script the generation of configuration files and import them all at once. Join our Discord to discuss setups, but remember: community advice doesn't replace your own testing.
