Better Call GPT – Plugin for Talking to Claude Code in Live

Insta Fusion released Better Call GPT, a free MIT-licensed Claude Code plugin that lets developers talk to their coding session through a realtime voice model, with the voice layer unable to approve permission prompts. The plugin binds to a single Claude Code session via /bettercallgpt:on, relays spoken work requests tagged ⟨v#n⟩, and defaults to Azure Voice Live running gpt-realtime-2.1, with GPT-Live (gpt-live-1) marked experimental and requiring headphones since echo cancellation is not advertised. It installs via `npx skills add insta-fusion/bettercallgpt -g` or `uv tool install "git+https://github.com/insta-fusion/bettercallgpt@v0.1.0"`, requires Node on macOS, and bills the user's own voice service account.

Talk while it codes. GPT Realtime talks back. A spoken “yes” never approves anything.

A realtime voice model keeps the conversation; only real requests reach your Claude Code session, which does the work in your repo and reports back by voice. In the launch video: fix a Stripe refund bug, draft an email you approve before it sends, and learn a Sylas combo, all mid-game. sequenceDiagram participant You participant GPT as GPT Realtime participant CC as Claude Code your session You- GPT: speak: "fix the refund bug and ship it" GPT-- You: small talk is answered right here GPT- CC: real requests arrive as a line tagged ⟨v 35;1⟩ CC- CC: reads, edits, runs tests, pushes CC-- GPT: progress and results GPT-- You: reads them back, you can interrupt any time Note over You,CC: Permission prompts go to your keyboard only. The voice cannot approve. 1. /bettercallgpt:on starts a voice process bound to this session only. It proves which session started it with zero keystrokes and refuses anything else. 2. You talk, full duplex, in your language. It opens in Chinese and answers in whatever language you just spoke; English tech words don't switch it. GPT Realtime decides what is chat and what is work. 3. Work is relayed as your words , tagged ⟨v n⟩ , so Claude treats it as you speaking. 4. Results come back by voice when they land; ask “how's it going?” mid-task. 5. It ends when you say so, type /bettercallgpt:off , or stay quiet for 10 minutes. npx skills add insta-fusion/bettercallgpt -g needs Node; macOS + Claude Code Then tell your agent: “set up bettercallgpt” . No Node? Paste this into Claude Code instead: Set up https://github.com/insta-fusion/bettercallgpt for me. it follows AGENTS.md https://github.com/insta-fusion/bettercallgpt/blob/main/AGENTS.md . It checks for uv https://docs.astral.sh/uv/ and your platform, installs the Claude Code plugin, creates an empty key file and runs a readiness check. You do two things yourself: 1. Paste your key into the file it names Azure Voice Live; OpenAI Realtime is experimental . Setup never asks for the key — don't paste it into the chat. 2. Type /bettercallgpt:on in a new Claude Code session and approve the start. A rising tone: you're live. Better Call GPT is free and MIT; the voice service bills your own account. Prefer to skip the skill? Install uv https://docs.astral.sh/uv/ , type /plugin marketplace add insta-fusion/bettercallgpt and /plugin install bettercallgpt@bettercallgpt , fill ~/.config/bettercallgpt/.env from .env.example https://github.com/insta-fusion/bettercallgpt/blob/main/.env.example , then /bettercallgpt:on . Or pin the release without the skill: uv tool install "git+https://github.com/insta-fusion/bettercallgpt@v0.1.0" . | | Voice Live default | GPT-Live | |---|---|---| | Model | gpt-realtime-2.1 | gpt-live-1 | | Echo | The service removes its own voice from your mic server echo cancellation , so open speakers are fine. | Echo cancellation is not advertised, so the call's start notes “use headphones”.

The voice cannot answer a permission prompt; you answer it on the keyboard. What your agent may already do without asking is still up to your Claude Code permission settings. - The start asks you first — unless Claude Code runs in auto or bypass mode, or an allow rule matches it. Don't allow-list it no bettercallgpt wildcard, no broad uvx rule : it opens your microphone and a paid connection. - What leaves your machine: your microphone audio, and what the voice needs to talk about the work your prompts, the agent's progress and results, permission prompts , go to the voice provider you configure. The call ledger stays local 0600 . See SECURITY.md › Privacy notes https://github.com/insta-fusion/bettercallgpt/blob/main/SECURITY.md privacy-notes . - It attaches only to the session that started it , proven with zero keystrokes, and refuses anything else. - The plugin is three small command files plugin/commands/ https://github.com/insta-fusion/bettercallgpt/blob/main/plugin/commands that only you can run: no hooks, and the voice process runs only during a call. They run the tagged release from GitHub through uvx ; release tags are published as immutable GitHub releases, so a tag cannot be moved after release. | | Today | Not yet | |---|---|---| | Agent | Claude Code CLI on macOS , any terminal, and the Claude desktop app's Code tab both proven live | Cowork runs in a VM: unsupported , Codex as a child agent VOICE BACKEND=process , unit-tested | | Voice | Azure GPT Realtime gpt-realtime-2.1 through Azure Voice Live; default, proven live, echo-cancelled: speakers OK and the Azure GPT-Live API gpt-live-1 , proven live; headphones | OpenAI Realtime API unit-tested; no echo cancellation: headphones | | OS | macOS | Linux/Windows: the Claude Code backend's peer check is macOS-only | | Orca | Works in any Orca https://github.com/stablyai/orca pane; when the pane proves itself needs the orca CLI the call also tells you when Claude is waiting on a permission prompt | long calls in that mode: unverified | Want it in another coding agent or CLI Codex, Gemini CLI, Cursor, Aider, … or on another voice model or OS?
