FlowDown is a fast, minimal AI chat app that makes working with large language models feel smooth, focused, and under your control. For guides, tips, and advanced setup help, visit flowdown.ai. Why FlowDown Lightweight and efficient Focus on your conversation, not the app. FlowDown launches quickly, stays out of your way, and keeps long chats responsive, even on busy machines. Rich formatting with Markdown Get clear, readable answers. FlowDown renders Markdown beautifully, so code blocks, bullet lists, tables, and headings in AI responses are easy to scan and use. Works with the tools you already have Connect to any OpenAI-compatible API, from major cloud providers to services running in your own home lab. If it speaks the OpenAI API, FlowDown can talk to it. Talk with text, images, and audio Show, not just tell. Paste screenshots, drop in images, or record your voice to ask questions. Use it to: - Transcribe meetings or lectures - Summarize voice notes - Ask about the content inside a photo Smooth, instant-feeling conversations Blazing-fast text rendering makes responses stream in fluidly, so you can start reading and refining your prompt without waiting for the model to finish. Automatic chat titles Stop hunting for the right thread. FlowDown names your conversations automatically based on their content, so you can quickly find that "API bug fix" or "Trip planning" chat later. Shortcut integrations Use FlowDown inside your workflows. With Shortcuts support, you can: - Send selected text from another app to your model - Generate drafts, summaries, or replies with one tap - Build custom automations that call your favourite model Privacy by design Your data is yours. FlowDown does not collect your chats. For maximum confidentiality, you can run models locally on your own machine with no external server involved.
