Semi

Talk to your pages.

A little character that sits on any page and answers out loud. It can summarize, translate, answer questions, scroll, and point. Everything runs on your device.

One local model.
Everything it needs.

No servers, no accounts, no API keys. The model runs on your GPU; the page never leaves your browser.

Talk to it

Hands-free voice chat: it listens, replies aloud, and keeps going. Whisper in, Kokoro out, all local.

Summarize

Turn any long page into a few clear sentences, spoken in a tap.

Translate

The whole page or just your selection, into the language you choose.

Answer

Ask about the page and get answers grounded in its actual content.

Scroll & point

Ask where the pricing is and Semi scrolls there and highlights it.

Draggable

Park the character anywhere. Hover for actions, click to talk.

Private by design. Your page is read only by a model running on your own machine. Nothing is uploaded and nothing is logged.
