Some ideas are quicker to draw than to describe.

Napkin is a free plugin for the agent you already use. When words are doing badly, your agent hands you a napkin in the conversation. Sketch it rough, press Send, and your agent reads the drawing.

  1. it should feel like a mountain, but rounder? I can't describe it

  2. Easier to draw than to describe. Here's a napkin.

Ask anything

The window is a mock of the client you already use. The napkin inside it is not — it is the same one your agent opens. Draw on it.

Three steps, and you never leave the chat.

  1. Add it to your agent

    Point your agent at one address. There is no account and no key, and it sits beside the tools your agent already has.

  2. Ask for a napkin

    Say it would be easier to draw, or type /sketch. Your agent opens a blank napkin in the thread and waits.

  3. Sketch and send

    Draw it rough and press Send. The sketch lands in your next message, the way an attached photo would.

Add it to your agent.

No account and no key.
