Dia (The Browser Company)
App : A product you use directly
Browser with an AI assistant that reads your tabs and drafts content from them.
Promising, still young compared to Comet.
Security reflects where data goes, requested permissions and incidents on record at the verification date. It is not a guarantee of zero risk: check the deployment mode and the connections you enable.
What it does, concretely
Juggling dozens of tabs, Slack threads, Notion documents and scattered emails wastes a significant amount of time every morning. Dia is a browser designed to bring that dispersed information together and make it immediately actionable.
In practice, Dia reads the content of your open tabs as well as your connected tools (Google Suite, Slack, Notion, GitHub, Calendar, and more) and answers your questions like a colleague who has read everything. It can generate a morning briefing, write a report, create a presentation with layout, or prepare your meetings with the right documents already open.
Dia is aimed at people who work across many tools simultaneously: project managers, developers, freelancers, or anyone who spends their day switching between applications. Profiles let you separate professional life, freelance work and personal use with distinct tabs and AI connections.
However, if you only use one or two tools and your browsing stays simple, Dia's advanced features will bring little added value. The browser is currently available only on macOS 14 or later with an Apple M1 chip or newer, which excludes Windows users and Intel Mac users for now.
