Runs on your backend
LM Studio, Ollama, llama.cpp, or any OpenAI-compatible server. eVi auto-detects what's live and recommends a model that fits your hardware.
Your AI.
Your hardware.
eVi is a local-first personal AI assistant. Chat with a model running on your machine, let it use tools, write code, generate images, run scheduled work, and drive your browser — from a terminal, a web app, or a native desktop window, all over one shared core. No cloud required.
pip install evi-assistant
One core. Every surface.
A single Python engine (evi/) drives a CLI, a web UI, and a desktop app — and talks to whatever local LLM you already run.
🧰
Real tools
Files, code execution, shell, web search, git, SQLite, PDF, OCR, vision, and voice — with a sandboxed run_python and granular per-tool permissions.
🧠
Memory & skills
Persistent cross-session memory, on-demand Skills (SKILL.md packets), and a hardware-aware model registry — all stored locally under ~/.evi.
🔌
MCP, both ways
Consume other MCP servers' tools, and run eVi as an MCP server exposing curated tools + memory resources to Claude Desktop, Cursor, and more.
🤝
Federation
Delegate heavy work to another eVi you own — keep a small model for chat and borrow your GPU box on the LAN, with no shared cloud.
⚡
Multi-agent
Ultracode fans work out across parallel subagents — decompose, solve, adversarially verify, and synthesize — for the tasks one context can't hold.
🛡️
Guardrails
Layered safety — regex → LLM judge → offline classifier — plus hooks, permission modes, trusted directories, and an MCP allowlist.
🔒
Yours, offline
Local-first by default. Your prompts, transcripts, and keys stay on your disk. Optional online model presets when you want them.
Three ways to run it
⌨️ Terminal
A fast Typer/Rich REPL. Chat, run tools, drive the whole agent from the command line.
evi chat🌐 Web
A FastAPI + SSE app with streaming chat, settings, plugins, evals, and federation panels.
evi web🪟 Desktop
A signed Tauri app for Windows, macOS, and Linux that wraps the web UI and self-updates.

Download the desktop app
Signed installers for every platform, built from the same 1.0 release. The app self-updates from here on.
All builds on the latest release page. Installers are minisign-signed for the updater — see the code signing policy. OS code-signing is being set up, so SmartScreen/Gatekeeper may warn on first run until it's live.
Extend it with Skills
A curated, open catalog of Agent Skills — author .docx/.xlsx/.pptx, triage a git repo, sweep for secrets. Install any of them in one line.
