eleven

Eleven is a free, open-source reverse-engineering desktop app for macOS, Windows and Linux where AI coding agents that speak the Agent Client Protocol can read binaries and Android apps, rename functions, leave notes and suggest patches while you approve each change.

Why it matters

For security researchers and developers who take apart apps and binaries. It puts agents like Claude, Codex or Gemini inside the disassembler, with every change logged and undoable.

Highlights

• Works with any Agent Client Protocol agent (the README lists Claude, Codex, Gemini, Cursor, Copilot and OpenCode), several per project, each in its own chat.
• Eleven serves its own MCP tools so an agent can open functions, switch views, rename, add notes, change types and propose byte patches you accept or decline.
• Opens Mach-O, ELF and PE binaries (via Ghidra or Rizin), Android APKs (via jadx), CUDA/HIP kernels as PTX, and ML model files such as GGUF and safetensors.
• Patching writes a separate copy, diffing compares two builds by function, and LLDB debugging is built in.
• Projects save as a single .eleven file with chats, renames, notes and patches.

Taken from the project's own README, docs or launch page. Claims about speed or accuracy are the maker's unless stated otherwise.

Worth knowing: Builds are not notarized yet, and the macOS installer clears the download quarantine. Only reverse-engineer software you have the right to analyze.
