Voice coding with Codex.

Talk to OpenAI's coding agent out loud and hear it answer. SKI gives Codex ears and a natural voice — free, and everything voice-related stays on your machine.

Why voice, why Codex

A terminal agent, without the terminal stare.

Codex is OpenAI's coding agent: point it at a repo and it plans, edits, and runs — a workflow made for handing off, not hovering. Voice coding completes that handoff: you say what you want the moment you think of it, and instead of watching output scroll by, you hear the result when it lands.

SKI does the voice part entirely on your machine. Speech becomes text locally and reaches Codex exactly like a typed prompt, through a small skill and plain files in your project; replies come back as a natural spoken voice, with the transcript in the pill or notch. SKI records nothing and uploads nothing — Codex simply sees text.

The written version

Five steps to a talking Codex.

STEP 01

Install SKI

One installer — DMG on Mac, EXE on Windows. A small widget appears — notch on Mac, floating pill on Windows. That's the whole interface.

STEP 02

Connect Codex — one click

SKI installs a small skill Codex already understands, at the user and project level — one click, once.

STEP 03

Type ski in Codex

In your Codex session, type ski. When the widget's dot turns green, you're connected: the project can now hear you and speak back.

STEP 04

Just speak

Say what you need — "fix the failing test," "add pagination to the API," "walk me through this diff." Codex gets your words as text, works, and answers out loud when it's done or has a question. Interrupt it mid-sentence any time — you'll still be heard.

STEP 05

Make it yours

Connect more projects — more Codex, or a mix with Claude Code and Cursor — each answering in its own voice. Screenshots ride your next sentence, silent mode keeps replies text-only on calls, and every control can be a hotkey.

Codex · FAQ

Good questions.

Which Codex does this work with?

OpenAI's Codex coding agent. One click in SKI installs the skill at the user and project level; then typing ski in a Codex session connects it to the widget.

Do I need an OpenAI subscription?

SKI is free for life. Codex is OpenAI's tool with its own plans — SKI adds the ears and the voice to whatever Codex access you already have.

Does SKI type into my terminal?

No. SKI and Codex exchange messages through a skill and plain files inside your own project — nothing is injected into windows or keystrokes, so any terminal setup works.

Does Codex really answer out loud?

Yes — when Codex replies, SKI speaks it in a natural neural voice generated on your machine, and shows the text in the pill or notch. Prefer quiet? Silent mode keeps replies text-only.

Is my voice recorded or uploaded?

No. Listening and speaking run entirely on-device; your audio never leaves the machine. Codex receives your words as text, exactly as if you had typed them.
