<p align="center"><strong>One AI coding agent for your whole codebase.</strong></p>

Sema is an **agentic code engine**. It indexes your repository once, locally, then
puts that index in front of whichever model you point it at — so every provider
starts out already knowing your code, and you can **switch provider and model
mid-conversation** without losing the thread.

It runs in three places, and they share one index and one session:

| Surface | What it is |
|---|---|
| **VS Code extension** | A Cursor-style chat panel with ten engines, agent permissions, and an opt-in redaction toggle |
| **`sema chat`** | The same agent as a terminal app — modes, tools, slash commands, resumable sessions |
| **MCP server** | Register sema with Claude Code, Codex, opencode, Grok Build, or Cursor and they get semantic search in their own CLI — no extension needed |

Use one, or all three.

> **Experimental** · **macOS and Linux** · Requires **Python 3.11+** · Nothing leaves your machine. [Disclaimer](docs/faq.md#disclaimer)
