Dia Review 2026: Pricing, Features and Verdict

What it is

Dia is a Chromium based browser from The Browser Company of New York, the team that made Arc. Its security FAQ says The Browser Company is now part of Atlassian, and new sign ins run through Atlassian's identity system with a Dia branded screen.

Dia pitches itself as a browser for the work day. Its homepage lists a Morning Brief that pulls together your calendar, inbox and key links; synthesis that turns scattered information from Slack, Notion, Teams and Google Workspace into shareable reports; context search across your tools; profiles for work and personal; split screen; AI generated decks; and organized tabs.

Unlike Comet or Gemini in Chrome, Dia is not trying to be an agent that roams the web for you. Its agent works on the page and context you approve, and is deliberately blocked from navigating to other sites on its own.

Pricing explained

Dia moved to three plans in August 2026:

Plan	Price	Includes
Better Browser	Free	Profiles, tab groups, split view, picture in picture, ad and tracker blocker, cross device sync; no AI
Better Answers	$10 per month on the plan card ($20 in the FAQ)	Ask Dia on any page, chat with context from your tools, models that do not store your data
Better Days	$100 per month	6x the tasks and chats, daily Morning Brief, reports, decks, recaps, meeting prep and follow up

The price conflict. On the day we checked, the Better Answers card showed $10 per month while the FAQ on the same page said $20 per month. We list both and recommend you confirm at checkout.

Usage is metered in Tasks. Simple requests can use a fraction of a Task; requests that pull in more tools, context or longer outputs use more. Your allowance resets each billing cycle and does not carry over. When it runs out, AI pauses instead of billing you overage. To keep going you can buy $20 blocks, by auto reload or one time top up, and bought blocks roll over for up to three months.

Trial and rollout. Every new user gets 14 days of Better Days with no card. Paid plans began rolling out to new Mac users on August 17, 2026. Existing users keep what they have for free for now, with at least 30 days' email notice before paid plans apply, and Windows is unchanged for the moment.

Value check. At $10 or $20, Better Answers is in line with a ChatGPT Plus or Claude Pro subscription, but you get one browser assistant rather than a full AI suite. Better Days at $100 is a premium price for a daily brief and polished decks; it makes sense only if those replace real hours each week. Compare against the Price Index.

Key features

Ask Dia on any page

The core feature on Better Answers: ask about the page you are reading and get an answer with that context. A chat session starts with no access to other tabs; you grant access when you need it.

Context from your tools

Dia connects to work apps such as Slack, Notion, Teams and Google Workspace so a question can draw on more than the open tab. This is where it differs most from consumer AI browsers.

Morning Brief

On Better Days, Dia builds a daily brief from your calendar, inbox and key links. Its security FAQ notes that proactive features like this send page content you viewed to a third party model to build the summary.

Reports, decks and recaps

Also on Better Days: Dia turns information into reports and presentation decks, writes recaps "in your voice" and handles meeting prep and follow up.

Agentic actions with guardrails

When Dia drives your computer, for example replying to email, it only sees what you saw and approved. For actions like fill form or draft email, it shows the exact content in a Dia controlled view and you choose whether to proceed. Calendar events stay in draft until you click Create.

Browser basics

Ads are blocked natively by default. Profiles separate work and personal contexts. Sync is end to end encrypted. Dia disables several Google services in Chromium, including Google account integration on startup and Google metrics reporting.

What users say

We did not find a Dia listing on G2, Capterra or the App Store with enough reviews to cite, and Dia has no mobile browser. Public discussion, mostly on Reddit, praises the clean design and Arc heritage. The loudest complaint since August 2026 is the move to paid plans, in particular the Morning Brief sitting behind the $100 tier, and users asking why a browser charges for AI built on outside models.

Privacy and security

Dia has the most complete public security documentation of any AI browser we compared.

Where data lives. By default, conversations, history, bookmarks and files are encrypted and stored on your device. When you use AI, the question and relevant context go through Dia's servers to AI partners. Sync is end to end encrypted, so Dia says its servers cannot read synced data.

Training. Dia's partners (Anthropic, OpenAI, Gemini, Azure, AWS) are contractually restricted from retaining or training on your data. Dia does use some content data to improve the product by default; it is not tied to your account, is kept 30 days and can be turned off in Settings, and organizations can disable it for everyone. Dia also trains small on device models, again with an opt out.

Certifications. The Browser Company completed a SOC 2 Type II examination for Dia covering security, confidentiality and privacy for calendar year 2025, with the report issued in 2026. It runs a HackerOne bug bounty and annual outside security assessments.

Not for regulated data. Dia is not HIPAA compliant and offers no BAA. Its FAQ says not to use it for PHI and suggests MDM controls to block AI on specific sites.

Prompt injection. Dia's stance is to assume prompt injections will happen and contain the damage. Its published controls: it will not automatically open or follow AI generated URLs, will not allow tools beyond what you intend, will not insert data into sites without approval, will not take irreversible actions, will not run agent mode on unapproved context, will not let the agent navigate to other websites, hides password fields and irreversible buttons from the agent, and does not pass URLs to the model verbatim. Dia also lists what injections can still do: shift tone, nudge answers toward misinformation, or trigger searches you did not ask for.

That design answers the concerns Gartner raised in its December 2025 advisory to block AI browsers, as reported by The Register, more directly than any rival does.

Who it is for

• Knowledge workers in Slack, Notion and Google Workspace. Context search across tools is the point.
• IT teams that need paperwork. SOC 2 Type II, MDM controls and org wide content sharing off.
• Arc fans. Same team, cleaner AI focus.
• Cautious users. The agent's limits are a feature if you worry about rogue actions.

Who should skip it

• People who want a free AI browser. Comet and the chat side of Gemini in Chrome are free.
• Anyone who wants an agent to book and buy across sites. Dia's agent will not navigate on its own.
• Phone first users. There is no Dia mobile browser.
• Healthcare and other regulated work. No HIPAA, no BAA.

Alternatives

• Comet: free, four platforms, a far more capable agent with a weaker security record.
• Gemini in Chrome: stay in Chrome; auto browse on Google AI Pro.
• Opera Neon: $19.90 per month with model choice and MCP.

Verdict

Dia is the most trustworthy AI browser on published facts: local storage, encrypted sync, contractual no training with its model providers, a SOC 2 Type II report and a prompt injection design that limits what a hijacked agent can do. It is not the most capable agent, and its new pricing is confusing at the low end and steep at the high end. Pick it for work, start with the free trial, and check the Better Answers price at checkout.
