Ever since generative AI and LLMs disrupted the world, companies have been looking for new ways to use them or create new, improved versions of the existing products. And there are still a bunch of fields we’re exploring on how to properly use AI.
Web browsers are one of the most common fields of exploration in the second half of 2025. At least from the casual users’ perspective. At the end of the year, there were almost no AI browsers on the horizon, but, by the end of the summer, there were already a dozen or so fully production-ready browsers you could use.
Companies noticed how people started to combine usual web browsing with the AI assistants inside the browsers. And then, things clicked! Both for the companies making browsers and LLM models. To stay relevant, they must make browsers that natively support AI. In short, an AI browser should run or assist AI tasks directly in the interface. But how?
What Types of AI Browsers Exist?
The best way to implement AI with web browsers is yet to be decided. Each company is trying to figure out its unique approach, but there are several categories I noticed forming:
- AI-native browsers – Run AI models inside the browser. Some even use local models when users want privacy (ChatGPT Atlas, Perplexity Comet, Opera One with Opera Aria, Brave with Leo AI)
- AI-augmented traditional browsers – Browsers with added AI tools (Microsoft Edge with Copilot)
- Antidetect browsers with support for AI/MCP – Browsers designed to hide the digital identity of a user’s browser profile, with added MCP support for communicating with AI tools like ChatGPT or Claude (Gologin)
- Agent-centric browser OS environments – Run in the cloud. They feel more like small systems than browsers (BrowserOS)
Research Methods
Most AI browsers are fairly new, so they don’t all support the same operating systems and have some features marked as “beta”. Because of this, it’s hard to create one perfect testing plan.
I still tried to make the process fair. For each browser I tried to figure out:
- Primary use case
- Unique features and integrations
- Multi-device support
- Integration with other tools
- Price

10. Arc Browser (Discontinued)
Arc Browser was an interesting focused alternative to Chrome that introduced features like Arc Max, an early attempt to bring AI into the browsing experience with a new way to handle and group tabs, on-page link previews, and Ask ChatGPT feature built in the browser.
Even though it had a loyal community, in 2025 The Browser Company (creator of Arc) shifted its focus to Dia, their new AI-native browser built on a faster and more secure foundation.
Arc still receives maintenance updates, but active development and all future AI work are now centered on Dia.
Top Use Cases For AI Browsers
After testing all these browsers, I noticed that each of them solves a different problem. AI browsers aren’t necessarily competing to do the same thing, many of them lean toward a specific type of AI workflow.
Here are the best use cases I’ve seen so far, based on real tasks and how each browser behaves when agents start taking action on the page.
Multi-Account Work, Automation & Agent Workflows
Some AI browsers are built to support long-running tasks and agent actions across many accounts. This is the space where Gologin and BrowserOS stand out.
Gologin works well when an AI agent needs to control multiple browser profiles through MCP. BrowserOS works when you want an agent to act inside tabs, apps, and cloud workflows.
Fast Research and Page-Aware Assistance
Browsers like Perplexity Comet and ChatGPT Atlas shine when the task is understanding or summarizing content. They feel like real research companions. The assistant stays on the page and gives fast answers without switching tabs.
Private, Local, and Anonymous AI Tasks
Brave with Leo AI is built for users who want privacy first. It avoids long-term logging, doesn’t require an account, and supports BYOM and local models for sensitive work. This makes it ideal for users who want AI help but do not want their content to leave the browser.
Everyday Browsing With Casual AI Help
Opera One, Dia, and Atlas are intended for everyday AI use. These browsers help with writing, drafting, summarizing, comparing, or translating on any page. Most of the AI access happens in a sidebar or inside the input box you are typing into.
Creative and Visual Workflows
Kosmik is in its own category. It’s designed for people who collect references, images, videos, or design assets while browsing the web.
Potential Risks of AI Browsers
AI browsers give assistants deep access to tabs, files, and personal data, but that also introduces serious privacy risks. Some tools like ChatGPT Atlas request permission to read emails, calendars, or screen content to act on your behalf.
If mishandled, this creates a single point of failure. A browser that sees everything. Researchers warn this centralization becomes a prime target for attackers and a potential leak source.
Another issue is how long these tools remember what you type. Some AI browsers log your prompts or browsing activity to “improve performance.” OpenAI and Google store this data unless you opt out, while Opera claims it doesn’t feed Aria chats into model training.
But past incidents show logs aren’t always safe: OpenAI once leaked user chats by accident, and thousands of ChatGPT links were indexed by search engines in July 2025 (Source).
There are also risks with browser extensions and AI agents acting on your behalf. Malicious plugins have stolen cookies or hijacked accounts, and prompt injection attacks – where hidden instructions on a webpage manipulate your assistant- are already real. If your browser can act like you, one tricked click could leak credentials, buy something, or share data. The trade-off is simple here: more power means more exposure to risks.
How To Choose The Right AI Browser (Checklist)
You saw that most AI browsers solve similar problems, but with a different approach. Some help agents run actions, some help with research, and some focus on privacy or creative work. When I test a new browser now, I look at the core task first. Once I know the primary use case, I can weigh out the pros and cons of each contender to choose the best one to fit my needs. Here’s a quick checklist that can help you pick the right one for you:
- Define the main job – Is it automation, research, privacy, or creative work?
- Match it to a category – AI-native, AI-augmented, antidetect with MCP, or browser OS?
- Check device support – Does it run on all systems you actually use?
- Look at AI and automation – Does it support agents, MCP, or local models if you need them?
- Review privacy controls – Can you control logging, data sharing, and local vs cloud use?
- Compare costs and limits – Free tier, usage caps, and team pricing if you work in a group.
- Run one real task – Try a small workflow you do every week and see if it holds up.
- Decide on a main and a backup – I usually keep one browser for heavy workflows and one for light tasks.
