Zuni

Zuni puts an AI chat sidebar inside Chrome.

It is a Chrome extension and AI email assistant that lets you chat with Gmail messages and any open tab, so you can ask for summaries, advice or a drafted reply without copying text into a separate app.

Zuni reads the context of your inbox, which means its drafting suggestions can be based on the actual thread in front of you.

The sidebar gives quick access to several models, including ChatGPT 4o, Claude 3.7 Sonnet, Gemini Flash 2.0 and DeepSeek R1.

That is handy if you like to compare how different models handle the same email or page.

Privacy is a selling point.

Chats are stored locally on your machine, they never touch Zuni's servers, and they are encrypted in transit.

For anyone wary of sending work email through yet another service, that matters.

Zuni works best as a writing and reading aid for people who spend much of the day in Gmail.

As an AI summarizer and email writer, it focuses on offering richer drafting options for your messages.
