A team of AI agents that build code together.
Chisel is an agentic coding platform built around multiple AI agents collaborating on your codebase. Where tools like Cursor, Aider, and Cline pair you with a single agent, Chisel coordinates a team — planner, coder, reviewer, tester — working in parallel on different parts of your project.
This repository (chisel-ui) is the desktop client. The Rust backend lives in chisel-core.
Early-stage personal project. Not ready for general use. The codebase is changing fast and the public surface is unstable. If you’re here from a link or search, expect rough edges.
No releases yet. No installer. No docs. No tests of brand promises. Don’t file feature requests yet.
Most agentic coding tools assume a single agent handles everything: read the code, plan the change, write it, verify it. That’s a useful abstraction, and it works for small changes — but a single LLM context has to juggle planning, recall, edits, and review all at once, and quality drops as scope grows.
Chisel bets the other direction: specialization beats generalism at the agent layer too. A planner that only plans, a coder that only edits, a reviewer that only critiques. Each agent gets a focused context window, a focused prompt, and a focused job. The platform handles the handoffs.
That’s the thesis. Whether it pans out is what this project is for.
Chisel is a desktop application with a separate backend service:
| Repo | What it is |
|---|---|
chisel-ui (this repo) |
Electron + React desktop client. The window you interact with. |
chisel-core |
Rust backend (Axum + Tokio). Owns agent orchestration, remote agent protocols, conversation state, and IPC with the desktop client. |
The two run as separate processes and communicate over a local socket / HTTP. Agents themselves run either embedded in chisel-core or as external CLI tools (Claude Code, Codex, OpenCode, etc.) that Chisel detects and routes work to.
Chisel is a personal-project fork of AionUi and AionCore by iOfficeAI. The desktop multi-agent foundation is borrowed from that project. The repositioning toward agentic coding — feature focus, branding, product direction — is the divergence. Not affiliated with the AionUi project or its maintainers.
If you’re looking for the original AionUi product (a general-purpose multi-agent cowork platform with office productivity assistants), go to the upstream — that’s a different product solving a different problem.
