Everything you need, nothing you don't

Zunery Nexus is intentionally minimal — a focused tool for AI-assisted work, built with privacy as a default.

Multiple AI Agents

Create unlimited agents, each with a unique name, model, system prompt, and temperature — tailored for any task.

Persistent Chat

All conversations are stored locally on your machine. Pick up where you left off — no cloud sync required.

Web Search Tool

Agents can search the web in real time and show inline sources with expandable result cards.

100% Local & Private

Your conversations never leave your device unless you connect a remote provider. No accounts, no telemetry.

Open Source

Fully open under MIT. Read the code, fork it, or contribute — the entire source is on GitHub.

Custom System Prompts

Shape agent personality and expertise with system prompts. Build a researcher, writer, or coding assistant in seconds.

Up and running in 3 steps

No account required. No configuration overhead.
