FlowDown is a fast, minimal, and developer-focused AI chat application designed to make working with large language models smooth, focused, and fully under the user’s control. Built for iPhone and iPad, FlowDown removes clutter and distractions, allowing users to concentrate entirely on high-quality conversations, long prompts, and structured AI outputs. Its lightweight architecture ensures quick launch times and consistently responsive performance, even during extended chats.

FlowDown is engineered to work seamlessly with OpenAI API–compatible services, making it a flexible front-end for a wide range of AI providers. Whether you connect to major cloud platforms or self-hosted services running in your own lab, FlowDown acts as a universal AI client. This makes it especially valuable for developers, researchers, and power users who rely on custom AI endpoints, API-driven workflows, and model-agnostic chat interfaces.

One of FlowDown’s standout features is its rich Markdown rendering engine, which transforms raw AI responses into clean, readable content. Code blocks, tables, bullet lists, and headings are rendered beautifully, making it ideal for coding assistance, technical documentation, prompt engineering, and structured note generation. This emphasis on clarity positions FlowDown as a practical AI productivity tool rather than a generic chatbot.

FlowDown supports multimodal interaction, allowing users to communicate with AI using text, images, and audio. You can paste screenshots, upload images, or record your voice to ask questions and receive contextual answers. Common use cases include meeting transcription, lecture summarization, image-based questions, and voice-driven note capture, making FlowDown a versatile AI assistant app for everyday and professional tasks.

To keep conversations organized, FlowDown automatically generates meaningful chat titles based on content. This intelligent labeling system makes it easy to revisit past discussions such as “API bug fix,” “Trip planning,” or “Content outline” without manual effort. Combined with blazing-fast streaming responses, users can read and refine outputs in real time without waiting for the model to finish—enhancing prompt iteration speed and workflow efficiency.

FlowDown also integrates deeply with Apple Shortcuts, enabling powerful automation. Users can send selected text from other apps directly into FlowDown, generate drafts or summaries with a single tap, and build custom shortcut workflows that call their preferred AI models. This makes FlowDown a strong fit for automation-driven productivity, content creation pipelines, and developer tooling on iOS.

Overall, FlowDown stands out as a minimal AI chat client, OpenAI-compatible AI interface, and professional LLM workspace for iOS users who value speed, control, and clarity. By combining fast performance, Markdown-first rendering, multimodal input, and automation support, FlowDown positions itself as a reliable and authoritative tool for anyone serious about working with modern AI models on mobile devices.
