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
