Neusis Code
AI That Ships

Five modes, infinite control. Architect bold. Code fast. Ask deep. Debug smart. Test fearless. AI with a clear role and unwavering focus.

Explicit Context Control · Works with Any Model · Open Integration

Privacy by Design

Explicit context inclusion and transparent token usage keep data disciplined.

Zero Lock-In

Use any LLM provider at cost, or bring your own API key. Switch anytime.

Examples-Led

Clear roles: Architect plans, Code implements, Ask explains, Debug diagnoses, Test validates.

Built for Control

Agentic coding without the chaos. Every feature designed to keep you in command.

Modes

On-task and under control. Modes restrict tool access and keep the context window clean—preventing hallucinations before they start.

Model Agnostic

Flexible and future-proof. Run any frontier or open-weight model via our at-cost selection, or bring your own API key. Zero vendor lock-in.

Examples

Clear roles that show what the agent can do: Architect (plan), Code (implement), Ask (explain), Debug (diagnose), Test (validate).

VS Code Native

Full VS Code compatibility. Your extensions, themes, and keybindings work out of the box. No relearning required.

Context Control

You decide what the agent sees. Explicit file inclusion, smart context pruning, and transparent token usage. Privacy by design.

Fast Iterations

Sub-second response latency. Streaming diffs. Inline edits that apply instantly without breaking your flow.

Frequently Asked Questions

Everything you need to know about NEUSIS

Modes constrain what tools and actions an agent can access for a given task. This prevents hallucinations, reduces context pollution, and keeps agents focused. For example, an "Architect" mode might disable file editing but enable diagram generation. You stay in control.
All of them. Neusis Code is model-agnostic. Use our at-cost model selection (OpenAI, Anthropic, Google, open-weight models) or bring your own API key. Switch models mid-session if needed. No vendor lock-in, ever.
It is a VS Code extension—and that is the point. Full compatibility with your existing setup. Your keybindings, themes, and settings stay intact. The difference: native agentic coding with Modes, context control, and model flexibility baked in.
You explicitly add files to the agent context. Nothing is included automatically. This keeps the context window clean, reduces token costs, and produces more accurate outputs. You see exactly what the agent sees.
Every core action has a default keybinding. Accept diff, reject diff, switch mode, add file to context—all accessible without touching the mouse. Power users can rebind everything. We optimize for flow state.
We pass through model API costs with zero markup. You pay exactly what OpenAI, Anthropic, or other providers charge. No hidden fees, no per-seat pricing games. Transparent usage-based billing.
