Two modes, one environment
Pick the right level of agency.
Most engineers spend most of their time in Pilot. Use Autopilot when the goal is clear and the work is bounded. Switch between them without leaving the window.
How Parser works
The agentic IDE for any model.
Parser is Entity's flagship: a cross-platform agentic IDE that runs on whatever model you bring. The orchestration layer — prompting strategies, multi-step planning, context compression, tool use, evaluation loops, and skills the agent loads on demand — is what closes the gap between any capable model and a frontier coding assistant.
Two modes share one environment. In Pilot, you steer: the agent proposes plans and diffs; you accept, refine, or reject every change inline. In Autopilot, you hand the agent a goal: it plans, executes, runs the terminal, calls tools, and ships — with everything visible, interruptible, and reversible.
MCP is native. Multi-agent orchestration is built in. Your code stays on your machine. The model bill, if any, goes to your provider — never to us.
What Parser does
Capabilities, end to end.
Everything Parser ships with, from supervised editing to autonomous multi-agent runs.
Pilot mode — supervised agentic coding with inline diff review
Autopilot mode — fully autonomous agents with live terminal
Native MCP support — every tool the protocol speaks
Multi-agent orchestration with isolated parallel sub-agents
Skills system: reusable, composable instruction packs
Token-efficiency engine: caching, compression, smart routing
Bring your own model — open-source, self-hosted, or premium API
Cross-platform desktop: macOS, Windows, Linux
