Infinity
Infinity is a free Mac app for AI chat, coding, and scheduled assistants. Mac users can branch conversations, work with local or cloud models, and keep project context in one place.
Who it's for
- Mac developers who want an AI coding workspace with save points, draft changes, and live preview.
- People comparing AI model responses who want to ask up to four models at once and explore each answer in branches.
- Mac users organizing ongoing work across chats, code, files, and assistants in shared projects.
Not the right fit if…
- People using a Mac with an operating system older than macOS 14: Infinity requires macOS 14 or newer.
- Windows or Linux users: the page describes Infinity as a Mac app and offers a Mac download.
How it fits your workflow
Download the Mac app, move it into Applications, and choose models. Use local models on the Mac or select a cloud provider, which may require a key or supported plan.
Ask a question and branch from an answer or phrase to explore follow-ups. Compare up to four model responses, or use Canvas to view the conversation paths.
For coding, start with an idea, folder, or GitHub project, then make changes with save points and live preview. Projects can keep chats, code, files, and memory together; assistants can run on schedules and request approval for actions.
Pricing

Key features
- Branching chats and Canvas
- Fork from a phrase or answer, open branches in a side pane, and use Canvas to view branches on a map. Breadcrumbs, branch chips, and search help users find their way back.
- Multi-model chat
- Send one message to as many as four models at once, with each answer becoming its own branch.
- Model choice by task
- Choose models for chat, code, voice, image generation, and file search. The app supports local and cloud models.
- Code workspace
- Start from an idea, a folder, or GitHub; plan or build an app; and review changes using save points, draft copies, and a live preview. Code in an answer runs in the chat's sandbox rather than on the Mac.
- Assistants and automations
- Create assistants with their own instructions, model, folder, voice, memory, and schedule. Assistants ask for approval before actions that have not been allowed.
- Projects
- Keep chats, code, files, and project memory together, and pass project context between chat and assistants.
