Plans	Free Free Trying Neon, or letting your own AI agent use a browser.	FreeOur pick Free Everyday browsing with an assistant for summaries and questions.
	StandardOur pick $19.90/mo Anyone who wants Neon's agents to do web tasks for them.	Comet Plus $5/mo Readers who want partner publishers' paywalled articles.

		Perplexity Max $200/mo, or $2,000/yr Heavy users running many tasks in the background.
Which plan to pick	If you're choosing Neon, it's for the agents, so Standard at $19.90 a month is the plan that matters. Month to month, so try it for one month on a real job. The free plan's chat is more basic than the free AI in Opera One, so only stay on Free if you want to plug in your own Claude or ChatGPT.	Use it free: the sidebar assistant alone is worth having, and most people never need more. Pro makes sense if you want Perplexity's research tools anyway, but don't buy it just for the browser agent, since Pro's credits are a one-off bundle. Nobody needs Max just for the browser.

Pros and cons

Attribute	Opera Neon	Comet
Pros	One of the strongest browser agents in reviews Several top models from OpenAI, Anthropic and Google in one subscription Free plan lets your own AI drive the browser Tasks keep each project's tabs and chat together Month to month, no annual lock-in	Free on Mac, Windows, Android and iPhone Feels like Chrome, with your extensions and bookmarks Answers about the page come with sources you can check Comet Plus is included with Perplexity Pro and Max Good at summaries and comparing tabs
Cons	$19.90 a month when Comet and Opera One have free AI sidebars Three separate modes (Chat, Do, Make) confuse new users Windows and Mac only, no mobile app Still labelled experimental by Opera Prompt injection risk, as with every AI browser agent	Repeated prompt-injection attacks found by researchers in 2025 and 2026; risky with logged-in accounts The agent is slow and sometimes gets stuck or gives up halfway Browser control moved behind Computer credits in September 2026, so Pro users lost an included feature Paying users complain of quiet limits, model downgrades and features being removed Amazon sued over its shopping agent, and the case is still running
