Now building Vivary. A Windows preview came out Sept 22, 2026.

Tools for the work you keep doing by hand.

I’m Jeff Kazzee. I build Callout, a hotkey that checks what you read, and Vivary, a desktop workspace for AI agents. Small tools that keep you in charge of the AI you use.

The Vivary mascot, a felt creature with antlers, riding a skateboard with a paintbrush, a potted flower, and a notebook.
The Vivary window: a project list and conversations in a sidebar, an empty chat headed “What are we working on?”, and a notice asking you to sign in to Claude Code.
Development build, Oct 3, 2026, before Claude Code sign-in.

I. The main project

Vivary

A desktop workspace for working with AI agents on your own projects. Conversations sit beside your notes, research, drafts, and code. You bring your own Claude Code or Codex account, and the files stay where you run them.

“Signals in the text itself. Not a truth check.”

The header on every Callout result.

II. Ready to download

Callout

Press a hotkey over anything you are reading. A small popover tells you whether the text is trying to manipulate you, and whether its claims hold up against sources it fetched.

How I work

Memory in files you can open. Claims with the sources behind them. Nothing runs that you can’t see, stop, or undo.

You decide
The tool proposes and you approve. A human gate is a feature, not a speed bump.
You can read everything
State is plain files on a machine you control, not a hosted store you cannot open.
You keep learning
A tool that thinks for you leaves you weaker. My tools show their work so you get sharper.
Sources or silence
Every claim carries where it came from. Unsure is a real answer.
