“I think, if the Vertical Tabs are coming to DIA this would really help a lot of people to try DIA. For me the Idea behind DIA sounds great. Can‘t wait till more features are coming.”
“When The Browser Company presented Arc, I really thought that a major focus would be design — not only how the browser looked, but how it worked. But the CEO never knew where he wanted to go and I now wonder if he even knew what made the company interesting in the first place. It is clear that this new browser will be completely forgotten immediately after launch. They should just save the money, let the people working there find other jobs and just call it quits. Maybe the CEO could build a bus”
“Let's create a skill that tells the dia team what is missing from Dia that existed in Arc that is still needed I'm more passionate about your dead product then your new one that's sad please change my mind.”
“Spoiler - it's a huge step backward. No vertical tabs, even. If the techbros were so obsessed with AI, why didn't they just bake it into Arc? This is the most Silicon Valley enshitification example I've seen in my life. Terrible. Just work on Arc. Nobody needs an "AI browser."”

“It's not happening guys. You blew it already. Time to admit to investors their money is gone.”
“after abandoning arc.... they can keep dia. I will never use anything from the browser company again because i just can't trust them to support their products beyond a year or two.”
“burned by them once, and done. Zen for the win”
“I liked Arc browser and used it for a while on macOS knowing that its coming to windows too. Then windows version came out I was happily install it and after using it for while i uninstall it from both device. I will never use a browser that is not available on both windows and mac and do not work equally on both. I won't even try this one until i know its coming to windows full featured. This is hilarious from a browser company. 😂”

“Trong quá trình sử dụng và trải nghiệm Dia Browser, mình còn khám phá thêm nhiều tính năng, tiện ích hay từ thanh ChatAI của DIA, ví dụ: 1. Đợt trước khi làm thumbnail hay là edit ảnh trên canva, mình hay phải screenshot màn hình rồi upload lên ChatGPT để hỏi xem Chat có gợi ý chỉnh sửa gì không, và thường nếu dùng ChatGPT free thì số lượng ảnh upload lên hay bị giới hạn. Cơ mà khi đã dùng Dia Browser thì mình vẫn ở nguyên tab Canva đó, mở thanh Chat lên và hỏi luôn "ảnh này ok chưa", là Chat củ”
“I think we should create a master thread in this subreddit dedicated to Dia Skills. For example, I know a lot of people, like myself, who want to use Dia to summarize YouTube videos. If someone develops a great YT Summarize Skill, we could share it here or in a Google Sheet for everyone to access. This way, people can benefit from more optimally written prompts, especially since the Dia Skills Gallery is limited and invite-only. Plus, it's unclear if the gallery will be open to niche websites, w”

“I am liking what you've done in Dia so far but til you have the option for vertical tabs I'm unlikely to use it. You've trained me to orient my whole surfing experience around them with Arc.”

Questions
Frequently asked
What is Dia?
Dia is an AI-powered browser that transforms your regular browsing experience into an intelligent workspace assistant. It connects all your work tools like Slack, Notion, Microsoft Teams, and GSuite, then uses AI to answer questions by searching across your entire digital workflow. Instead of switching between dozens of tabs and apps, Dia provides a unified interface that understands the full context of your work environment.
Is Dia free to use?
Dia offers a free "Better Browser" plan that includes a clean browsing experience with profiles, tab groups, split-view capabilities, and built-in ad blocking, but excludes AI features. The AI-powered plans cost $20/month for "Better Answers" and $100/month for "Better Days" with expanded usage and automation features. New users get a 14-day free trial with access to the full Better Days plan.
What is the Morning Brief feature?
The Morning Brief is an automated daily overview that Dia creates before your workday begins. It compiles your calendar events, inbox priorities, and key links into a single, organized briefing so you can quickly understand what's ahead. This feature is available with the Better Days plan and helps eliminate the morning scramble of checking multiple apps to get oriented for the day.
How does Dia organize browser tabs differently?
Dia automatically organizes related pages into tab groups with meaningful names like "Design Review" or "Q2 Planning" instead of showing generic page titles. It also features Live Work integration that pulls active projects from platforms like GitHub and Notion directly into the tab bar for single-click access. Additionally, you can create separate profiles for work, freelance, and personal contexts, each with distinct tabs and logins.
Can Dia help with meeting preparation?
Yes, Dia automates meeting preparation by opening relevant documents, agendas, and notes while providing gentle countdown reminders. It features a split-view that lets you see meetings on one side and related documents on the other, with layouts that remember your preferences for recurring events. The AI can also pull context from across your connected tools to ensure you have all relevant information ready.
What work tools does Dia integrate with?
Dia integrates with popular workplace applications including Slack, Notion, Microsoft Teams, and GSuite. When you ask questions, the AI searches across all these connected tools, plus your open tabs and documents, to provide comprehensive answers with full context. You have granular control over which tools connect to your workflow and can manage these integrations according to your privacy preferences.
Can Dia generate reports and presentations?
Yes, Dia can generate reports and presentations by pulling scattered information from various sources across your workspace and organizing it into coherent documents ready for sharing. This feature is part of the Better Days plan and helps eliminate the time-consuming process of manually gathering information from multiple tools and formatting it into professional deliverables.
How does Dia handle privacy and data security?
Dia prioritizes privacy with built-in tracking and ad blockers, end-to-end encryption for sync data, and privacy-focused AI models that don't store user data. You have granular control over which tools connect to your workflow and whether the AI remembers preferences. The company never sells user data or uses it for advertising profiles, and offers enterprise features including single sign-on and administrative controls.
