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

Pick Comet if

• Fits if you want an assistant to do multi-step web chores, like shopping or scheduling
• Works for Perplexity subscribers who want its AI search inside the browser

Look elsewhere if

• Not for you if you want to know the free limits up front, as neither app store states them
• Pricey if you end up wanting Perplexity Max, which is listed at $200 with no billing period shown
• Skip it if you'd rather your browser didn't act for you, since the assistant is the whole point
• Watch out: nothing on record says whether sync, extensions or saved passwords exist, and there's no API or integration list
• Watch out: Perplexity's own site couldn't be read, so Mac and Windows availability comes from press coverage

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

Comet

• The App Store lists Perplexity Pro at $20.00 and $200.00 and Perplexity Max at $200.00 as in-app purchases, without stating a billing period.
• Google Play lists in-app purchases from $4.99 to $249.99 per item, and neither store says which features or limits depend on a paid plan.
• Perplexity's website could not be read when checked, so Mac and Windows availability comes from press coverage rather than a vendor page.

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.

Comet

Comet Assistant

A built-in assistant takes on assigned tasks such as shopping, scheduling and research. Its actions are shown as it works, and the user can step in at any time.

AI search with page context

AI search is built into the browser and uses the context of the page being viewed, so questions can be asked and answered without leaving the site.

Summaries across tabs

Smart summarization condenses content from all open tabs at once, not only the page currently on screen.

Voice mode

On mobile, voice mode lets a person talk to the assistant to find information across the tabs they have open.

Built-in ad blocker

An ad blocker removes spam and pop-up ads on mobile as on desktop, with a whitelist for sites the user trusts.

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.
