ModelPiper Chat

Ask. Then let it work.

Chat with models running on your Mac, free and with no account. When you want more than an answer, give the agent your tools.

Download for Mac

Apple Silicon · macOS 26+ · Free to start

01 / Local

Your models. Your Mac.

Run open models on Apple Silicon with ToolPiper’s llama.cpp engine, or use Apple Intelligence. No account and no caps.

Any GGUF model

Download as many models as you like and switch between them.

Apple Intelligence

Use Apple’s on-device model, running on the Neural Engine.

A local API

Point your own apps at the same models through an OpenAI-compatible API.

02 / Agent

More than an answer.

With Pro, the agent reads and edits files, drives the browser and commits to Git, and shows each step as it goes.

Work you can see

File diffs, terminal output and Git status appear in the chat as the agent works.

Chats that keep running

Run several chats side by side. Closing the tab doesn’t stop one. Only Stop does.

A workspace per chat

Each chat keeps its own files, tasks and browser page.

03 / Voice

Or just say it.

Voice chat, dictation and text-to-speech run on your Mac and are free on every plan.

Voice chat

Talk with a local model and hear it answer.

Dictation

Hold a key, speak, and the text lands where your cursor is.

Talk to your Mac

Turn on dark mode, set the volume or start a Focus by asking.

Local chats stay on your Mac.

With a local model, your prompts, files and replies are processed on your device. Connect a cloud provider when you want one, with your own keys.

Good to know

Questions,
answered.

Find what fits your Mac
Is Chat free?

Yes. Chatting with local models is free with no account, including tools from any MCP server you install. Pro ($10/mo) adds the agent’s browser, files and Git tools, RAG over your files, and cloud models with your own keys.

Can I use cloud models like GPT or Claude?

Yes, with your own API keys, which ToolPiper keeps in the macOS Keychain. Cloud requests go through ToolPiper’s proxy, which is part of Pro.

Which model should I start with?

That depends on how much memory your Mac has. Fit shows which models fit your Mac and estimates how fast each one generates.

Does voice cost extra?

No. Voice chat, dictation and text-to-speech are free on every plan and run on your Mac.
