BitFun brings several ways of working into one polished desktop experience:
- Code for understanding repositories, planning changes, editing files, running commands, reviewing diffs, and shipping software.
- Cowork for research, documents, presentations, spreadsheets, PDFs, visual explanations, and everyday knowledge work.
- Claw for persistent personal assistants with their own identity, tools, memory, and scheduled work.
You can stay in control through chat, work directly in the integrated workspace, delegate focused work to subagents, or let BitFun operate supported browser and desktop flows. The same project can continue through a terminal interface, a paired mobile browser, a remote machine, or a connected messaging service.
BitFun starts with serious engineering work rather than a lightweight chat window. Planning, debugging, research, review, parallel work, computer use, and team-style collaboration are distinct working modes—not one generic prompt box.
Your desktop and workspace remain the center of gravity. BitFun gives you explicit permission controls, local session history, configurable memory, and the freedom to connect the model providers and tools that fit your work.
Editor, terminal, files, Git, browser, previews, sessions, and agent conversations live together. You can move from a request to the underlying work without constantly switching applications.
Create polished documents, editable slide decks, spreadsheets, PDFs, diagrams, dashboards, and interactive tools. Research a topic, turn the findings into an artifact, then refine it in the same session.
Create custom Agents and subagents, combine Skills, connect MCP services, build Mini Apps, use lifecycle hooks, or selectively bring in capabilities from other agent ecosystems.
Pair a phone by QR code, connect over LAN or relay, control another signed-in device, work inside SSH or container environments, or continue selected workflows from Telegram, Feishu, or WeChat.

BitFun is an actively developed 0.x release. The Windows, macOS, and Linux desktop experience is the primary product today. Some capabilities—such as Pages, selected external-source compatibility, and parts of the wider mobile vision—are clearly labeled Preview, Beta, or In progress in this Wiki.
That distinction matters: this Wiki celebrates what BitFun can do while staying honest about what is still becoming.
BitFun is open source under the MIT License. If the idea of a flexible, local-first agent workspace resonates with you, star the project, try a release, and tell us what you want agents to become.
