What do you need to get done?

Live-show operators

Run a show

One console: call up video, audio, show control, show ops, front office, the shop, infrastructure, lighting and the specialist tools as resizable panels, and save your arrangements as views.

Open the console

Anyone writing prompts

Write better prompts

Write, enhance, score, and compare prompts in a browser sidebar or the web app, and keep the good ones in a library.

Notion workspaces

About Dave

The approach

Each tool starts from a real job and is built to get out of the way once you know it.

Runs where you work

AV tools run in the browser and keep working offline. Notion agents run on Notion AI, and widgets embed in a Notion page.

Your data stays local

AV tools save to your browser and export to files you keep. Nothing here needs an account on this site.

Works alone or together

Use one tool, or pass show details from one AV tool to the next. Every handoff asks before it imports anything.

Plain pricing

AV tools and widgets are free. Prompt Lab has a free editor and an optional Pro plan at $9/month.
