LlmHelper

Windows desktop client. Requires .NET 8 Desktop Runtime (the installer will offer to install it if missing).

Install

SmartScreen may warn about an unrecognized publisher. Click More info → Run anyway.

Audio

Audio → Audio Studio in the app:

• Voice tracks from a script: several speakers, OpenAI and Azure voices, per-line style and speed.
• Editing: replay or redo single lines, splice in your own recordings, export MP3 or WAV.
• Transcription: transcribe audio or video files to text and subtitles.

Save your OpenAI key (and optionally Azure) under API Keys first.

Audio for AI agents. The same features are available to Claude Code as an MCP server, installed separately: see LlmHelper Audio. It reads the keys you saved here. Together with Jig, an agent can film a demo of a Windows app and narrate it.
