Connect Claude and ElevenLabs

Step-by-step, for people new to Terminal - install Claude Code and sign in with your Claude plan, or use an Anthropic API key, and create an ElevenLabs API key.

DemoVexa uses two services through your own accounts: Claude writes the scripts and builds the videos, and ElevenLabs records the voiceovers. This page walks through connecting both, one click at a time. The same guides are in the app: press Step-by-step guide in setup, or Guide in Settings → Claude and Settings → ElevenLabs.

#Claude: with your Claude login

Use this if you have a Claude Pro or Max plan. It's a one-time setup in Terminal (PowerShell on Windows).

  1. Open Terminal.

    • Mac: press ⌘ Space, type Terminal and press Return.
    • Windows: press the Windows key, type PowerShell and press Enter (no need to run it as administrator).
    • Linux: press Ctrl Alt T.

  2. Install Claude Code. Paste this and press Return / Enter. It takes about a minute.

    Mac and Linux:

    curl -fsSL https://claude.ai/install.sh | bash

    Windows (PowerShell):

    irm https://claude.ai/install.ps1 | iex

  3. Sign in. Type claude and press Return. If it asks how to sign in, choose Claude account with subscription. Your browser opens: sign in with the account that has your Pro or Max plan and click Authorize. When Terminal says you're signed in, type /exit or close the window.

  4. Test it. Back in DemoVexa, press Test Claude. It should say Claude answered … via your Claude login.

  6. Press Test Claude.

#ElevenLabs

  2. Click your profile at the bottom left → Developers → API keys (direct link).
  3. Click Create API key and name it DemoVexa. Leave it unrestricted, or if you restrict it, allow Text to Speech, Voices (read and write) and User (read, so DemoVexa can show the characters you have left). Click Create, then Copy: the key is shown only once.
  4. In DemoVexa, paste it into ElevenLabs API key, click Save, then Test ElevenLabs. It should say Connected with how many voices you have.
