eVi — personal AI assistant

eVi 1.0 — shipped and public. Local-first personal assistant. Chat with a model on your hardware, let it use tools, generate images, automate scheduled tasks, drive your browser, and reach the same core from a terminal, a web app, or a native desktop window.

One Python core, three frontends, no cloud round-trips.

Requirements

Component	Why	Notes
Python 3.13+	Core runtime	3.13 tested
Git 2.17+	Optional — `evi worktree`	2.28+ for `init -b`
An LLM backend	One of LM Studio / Ollama / llama-server / any OpenAI-compatible endpoint	LM Studio default
NVIDIA GPU	Optional — speeds up local LLMs and ComfyUI image gen	CPU fallback works

Quickstart

Package name: the project is eVi, but the PyPI distribution is evi-assistant (the bare evi name was taken). Install with pip install evi-assistant; the import package and CLI command are both still evi (import evi, run evi).

pip install evi-assistant                # from PyPI
evi models recommend                     # honest read on what'll fit
evi chat                                 # off you go

Or work from a clone (editable install, all extras):

git clone https://github.com/evi-assistant/evi-ai.git evi && cd evi
py -3.13 -m venv .venv
.venv\Scripts\Activate.ps1            # Windows
# source .venv/bin/activate            # Linux / macOS

pip install -e .

# Pick a backend. LM Studio + a tool-capable model is the easiest first run.
# In LM Studio: load qwen2.5-7b-instruct → Developer → Start Server.

evi models recommend                    # honest read on what'll fit
evi chat                                # off you go

/help inside the REPL lists every slash command (goal tracking, plan mode, auto-approve, model switching, user-defined templates).

Three-machine setup

eVi is built to span machines. A typical setup:

Machine	Role	Backend
AI server (P40)	LLM host + web UI	Ollama or llama-server, `evi web` on port 8000
Desktop (16 GB)	Full power workstation	Local LM Studio
Laptop (2 GB)	Thin client	Profile points at the AI server

See docs/multi-machine.md for the wiring.

Major commands

evi chat                           Start the REPL
evi web --host 0.0.0.0             Run the FastAPI + SSE web UI
evi dream                          Curate long-term memory from yesterday's chats
evi models recommend / list / use  Hardware-aware model selection
evi models pull <ref>              Pull via Ollama tag or hf:<repo>:<file>
evi schedule add / list / run-now  Cron-style scheduled prompts
evi scheduler                      Foreground daemon for scheduled tasks
evi worktree create <branch>       Spin up a git worktree for parallel work
evi profile add home --backend …   Per-machine config overlays
evi voice listen / speak           STT + TTS
evi mcp list-tools                 Show MCP server-provided tools
evi mcp serve                      Run eVi AS an MCP server (other agents use eVi's tools)

Configuration

Per-user config lives in ~/.evi/. Highlights:

~/.evi/
  config.toml         primary settings — backend, tools, auto-approve
  profiles/*.toml     overlay profiles for per-machine config
  memory/*.md         long-term memory; `.attic/` holds soft-deleted entries
  skills/<name>/      installed skill packets (SKILL.md + assets)
  commands/<name>.md  user-defined slash command templates
  scheduled/*.json    saved scheduled prompts
  hooks.toml          before/after_tool_call hooks
  mcp.json            MCP server list
  transcripts/        per-session JSONL (input to dreaming)
  logs/               run logs (dreams, scheduled tasks)

See docs/configuration.md for the full reference, the feature catalog for what every feature does + how to use it, and surface parity for the CLI ↔ Web ↔ Desktop map.

Optional dependency groups

pip install -e '.[web]'        # FastAPI + uvicorn for `evi web`
pip install -e '.[mcp]'        # Model Context Protocol client
pip install -e '.[scheduler]'  # APScheduler for cron-style tasks
pip install -e '.[downloads]'  # huggingface_hub for `evi models pull hf:...`
pip install -e '.[web-tools]'  # DuckDuckGo search + BeautifulSoup
pip install -e '.[stt]'        # faster-whisper + sounddevice
pip install -e '.[computer]'   # pyautogui for mouse/keyboard control
pip install -e '.[dev]'        # pytest + ruff

Or all at once:

pip install -e '.[dev,web,mcp,scheduler,downloads,web-tools,stt,computer]'

Development

pip install -e '.[dev]'
pytest -q              # ~1,300+ unit tests (E2E are opt-in: -m e2e)
ruff check evi apps    # style + bug-pattern lint

See docs/development.md for architecture notes, and docs/self-build.md for developing/building eVi with eVi (the EVI.md project context + the one-command scripts/build-desktop build).

Safety posture

Default tool toggles lean conservative: shell, subagent, web, voice, computer, gmail, outlook, image, and mcp are all OFF until you flip them in config.toml.
auto.auto_approve lists categories that run without prompting. The defaults are fs, code, memory, skills, image. computer is never in this list — every mouse click / keystroke prompts.
Hook vetoes (~/.evi/hooks.toml) can block any tool by glob match.
Soft-delete memory sends "forgotten" entries to ~/.evi/memory/.attic/ so the dreaming engine can't permanently lose anything.
