Dia vs Opera Neon (2026): which should you pick?

Pick Dia if

• Fits if your working day is spread over Slack, Notion, Google Workspace and Teams
• Works for people who want a daily brief and meeting notes pulled up before each call

Look elsewhere if

• Skip it if you want AI for free, as the free plan is the browser alone and chat starts on the paid plans
• Pricey if you want the Morning Brief and reports, which need Better Days at $100 a month
• Not for you if you browse on a phone or Linux, and on Windows the paid plans aren't live yet
• Watch out: the plan card says $10 a month for Better Answers while the FAQ on the same page says $20
• Tight if you use the AI a lot, since it pauses when your Tasks run out unless you buy $20 credit blocks

Pick Opera Neon if

• Fits if you want an AI agent that clicks through web pages for you
• Makes sense if you pipe browser sessions to outside AI tools through MCP

Look elsewhere if

• Skip it if you want the agents free, as they need Standard at $19.90 a month
• Not for you if you use Linux or a phone, since only macOS and Windows are listed
• Watch out: the FAQ says page content goes to Opera's and OpenAI's servers, deleted after 365 days
• Watch out: Neon Chat and the research agents run in the cloud, and Neon Do plans its actions with cloud models

Dia

• The free Better Browser plan has no AI features; chat needs Better Answers at $10 per month, and the Morning Brief and reports need Better Days at $100.
• Paid usage is metered in Tasks. When the monthly allowance runs out, AI features pause unless extra usage is bought in $20 credit blocks.
• Dia is offered for macOS and Windows only. Paid plans began with new Mac users on August 17, and the FAQ says they do not yet apply on Windows.
• The plans page disagrees with itself: the Better Answers card shows $10 a month, while the FAQ further down the page still says $20.

Opera Neon

• Available for macOS and Windows only, according to the FAQ.
• The agent features, Deep Research and full model choice need the paid Standard plan; the free tier has basic chat.
• The FAQ says page content is sent to Opera's and OpenAI's servers and deleted after 365 days, and that Opera does not train AI models on it.
• Neon Chat and the Research agents run in the cloud, and Neon Do uses cloud language models to plan its actions.

Dia

Chat with context from tabs and tools

On paid plans, a question asked on any page is answered using open tabs and connected tools such as Slack, Notion, Google Workspace and Microsoft Teams.

Morning Brief

A daily brief lays out the calendar, inbox and key links before the workday starts. It is part of the Better Days plan.

Reports, decks and recaps

Dia gathers context scattered across tools into a shareable report or a slide deck with headers and layout. These are part of the Better Days plan.

Meeting prep

Before a call, Dia opens the meeting page, agenda, notes and related documents and shows a countdown to the start time.

Profiles, tab groups and split view

Profiles keep work, freelance and personal tabs, logins and AI separate. Related tabs are grouped under descriptive names, and split view layouts are remembered.

Privacy controls

Ad and tracker blocking are built in, memory and chat personalization can be switched off, and synced data is end-to-end encrypted. Dia for Work adds SSO and admin tools.

Opera Neon

Neon Do

An agent that works with the page you are viewing, handles tab commands and scheduled tasks, and connects with Google tools.

Neon Chat

AI chat that uses your open tabs as context, with image and video generation and web app creation.

Research agents

Three agents: Deep Research for structured reports, One-Minute Research for quick overviews, and Local Research that uses your own browsing context.

MCP and CLI

Neon acts as an MCP server so tools such as Claude Code, Lovable and n8n can connect to the live browser session. The connection is read-only by default.

Neon Cards

Reusable instructions, like skills, that tell Neon how to handle a kind of task. They work across chat, Do and research.

Built-in Opera tools

An ad blocker and a free VPN that needs no subscription or login.
