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.

Open source and transparent

Every line of code is available on GitHub. Inspect it, audit it, or adapt it for your own setups. You can see exactly how your AI client works.

Free trial and open code

FlowDown is fully open source, and we provide a free trial so you can confirm it fits your workflow before buying.

Source code and trial builds are available at:

https://github.com/Lakr233/FlowDown

To try it, open the Releases section and download the latest trial version.

Local models

For offline, private usage, FlowDown can run models locally on Apple Silicon devices with sufficient memory.

Supported model families include:

Cohere, Gemma, Gemma2, Gemma3, InternLM2, Llama / Mistral, OpenELM, Phi, Phi3, PhiMoE, Qwen2, Qwen3, Starcoder2, MiMo, and GLM4.

This gives you:

- Full control over your data

- No dependency on external servers

- The ability to experiment with different open models

Remote models

A complimentary remote model is included so you can start chatting immediately. This starter service is best-effort, with rate limits and no uptime guarantee.

For consistent, reliable use, we recommend:

- Bringing your own API, or

- Hosting your own inference server on local or home-lab hardware

FlowDown supports all OpenAI-compatible endpoints, making it ideal for connecting to tools like Ollama and LM Studio running on your own machine for maximum privacy.

Some setups require technical knowledge. If you are new to self-hosted AI or custom endpoints, please read our documentation carefully; the app can be challenging without it.

We strongly recommend using the free trial before purchasing, as refunds may not be available. For advanced or enterprise use, configuration examples and best practices are documented on our website.
