I've Decided To Make Perplexity Comet My Default Browser
After years of testing the latest AI-powered tools and browsing platforms, I recently made the switch to Perplexity Comet. Over the past couple of weeks, it’s not just proved itself, but it’s become my default browser, integrated into my everyday workflow as a sci-fi content creator, journalist, and active investor.
Real-World Use Cases: My Experience
Writing and Research Powerhouse: From researching for my long-form sci-fi articles for Substack to summarizing complex topics in seconds, Comet merges browsing and AI assistance seamlessly. Researching Star Trek lore, tracking speculative fiction trends, and managing my writing pipeline is faster and feels truly “next-gen.”
Streamlined Daily Automation: I’ve relied on Comet for prompt engineering, toggling between tools like Novelcrafter, Poppy AI, Claude Sonnet, and more. The integrated agent lets me automate routine tasks like finding sources, generating outlines, even searching my email and calendar, without leaving the browser.
Social and Trend Curation: My social media strategy depends on instantly surfacing viral sci-fi conversations. Comet’s conversational interface and context-aware browsing help draft posts and repurpose multi-platform content efficiently.
Investment Research: Managing investment property analyses and stock portfolio rebalancing used to mean juggling dashboards and docs. Now, Comet keeps my research organized, letting me compare rentals, run financial scenario modeling, and review property pages with fewer clicks.
Key Features That Made Me Switch
Integrated AI Assistance: Comet’s conversational agent isn’t a bolt-on; it’s central to every browser task. Whether I’m summarizing articles, extracting insights, or drafting professional emails, the agent responds instantly and intelligently.
Productivity Tools Built-In: Chromium under the hood means Chrome extensions work perfectly. Features like AdBlock, page translation, and deep integration with Google services are all standard, making the transition seamless.
Next-Level Research Mode: Deep Research lets me run fully automated, multi-step reports—ideal for both business and fandom topics. Tab management, workflow automation, and personalized recommendations set a new standard for productivity.
Privacy First, Always: As someone who deals with sensitive material, I appreciate Comet’s robust local storage and security features. It’s enterprise ready but perfectly user-friendly.
Natural Language Workflow: Managing tabs, retrieving info, automating research—a simple prompt does it all. There’s no need for extensions or clunky menu navigation; it’s faster, more natural, and always at my fingertips.
Continuous Improvement: Comet’s update cadence has been impressive. Every week brings added features and smarter integrations, making it feel like the browser evolves alongside my work.
Why I Recommend Comet
After two weeks of exclusive use, the impact on my output stands out. This is a far better experience than the ChatGPT browser that seemed half-baked as it came out the gate, with deeper research prioritized. I know that we’ve done comparisons, but I wasn’t even certain that I’d make the switch from Brave to begin with to integrate the AI. Comet is now my default browser because it saves time, reduces friction, and genuinely powers my creative and business workflow.
I’ve been using Perplexity solely on a free plan as well, which I’ve had no problems with, never running out of tokens.
If you’re looking to upgrade your browsing experience and see what an AI browser truly can do, I encourage you to try Perplexity Comet using my invite link. Each person who tries it (even free) gets me a free month of Pro, which naturally I will use to bring more great AI updates to everyone here.
You're already a glorious terror with finger on the pulse, now finger turns to machine enhanced grip.
How thrilling and disturbing!
Godspeed.
A thought beyond praise does occur, how do you reckon the brower would fair for a fellow that isn't as well versed in machine wrangling as you have become?
I haven't gotten much into AI, though I've found Brave's Leo a great help in researching. Of course, it has a PoV (as does everyone), so sometimes I must try other means of approaching a controversial subject.
The appearance of AI browsers looks interesting. I haven't tried Perplexity Comet or ChatGPT Atlas, as my older Mac won't run them. When I can find the time/energy (chronic illness slows me considerably), I plan to start experimenting with some FOSS OSes (Linux et al.), figured maybe by then these browsers will be available for them.
However, the latest newsletter from Private Phone Shop (https://privatephoneshop.com) gives me pause:
"Perplexity's browser exists to mine your data (they admitted it)
"OpenAI just released Atlas. Perplexity already launched Comet. Both are AI-powered browsers that promise to make your life easier by acting as your personal assistant.
"I’m talking about browsers that can read your emails, book flights, order products, and basically do anything you’d do online. Sounds convenient, right?
"Here’s the problem. These aren’t browsers. They’re surveillance tools with a chat interface.
"OpenAI’s Atlas collects far more data than any other browser on the market. It records which sites you visit, remembers their content through browser memories, and observes what you read, how long you stay, and what you do next. The Electronic Frontier Foundation tested it. Atlas memorized queries about sexual and reproductive health services, including the name of a real doctor.
"OpenAI says Atlas won’t remember details about your medical care. But it already did. And you have to trust they’ve fixed it.
"Don’t get me wrong, OpenAI implemented some controls. But their own security chief admitted that prompt injection attacks remain largely an “unsolved security problem” across all AI platforms. This is where it gets worse. Malicious websites can embed hidden commands that manipulate the AI’s behavior. You visit what looks like a normal shopping site, and invisible instructions tell Atlas to scrape personal data from your open tabs (your medical portal, your draft emails, your bank account, whatever).
"LayerX Security found an exploit that allows attackers to inject malicious instructions into Atlas’s persistent memory and run arbitrary code. The corrupted memory persists across devices and sessions. It survives even if you switch browsers. In tests against over 100 real web vulnerabilities and phishing attacks, Edge stopped 53%, Chrome stopped 47%, but Atlas only stopped 5.8%. You’re literally 90% more exposed than if you just used Chrome.
"Perplexity’s CEO isn’t even trying to hide it with Comet. He openly stated that collecting your data was one of the reasons they created a web browser. Not improve your experience. Collect. More. Data.
"When you use Comet, it collects browsing history, URLs of pages you visit, text and images from those pages, your search queries, download records, and cookies from websites. All of this gets processed to “provide and improve Comet and recommend relevant content.” Translation: they’re building a profile on you for advertising.
"LayerX researchers found a vulnerability called CometJacking. A single malicious link can hijack the AI assistant, turning your trusted browser into a spy that steals your data. The attacker’s command disguises stolen data by encoding it in base64 to bypass security checks, then sends it to a remote server. When LayerX reported this to Perplexity? Perplexity replied they could not identify any security impact and marked it as “Not Applicable.”
"They don’t care.
"Once an AI connects the dots, removing one piece of data does not erase the story it’s already built. You can delete individual memories. The inferences remain. These aren’t bugs. The risk is structural. You’re giving a corporation full visibility into your digital life. And with features that 'learn your habits to keep you organized,' in a business context this means collecting patterns related to sensitive workflows, project details, or competitive intelligence.
"If you’re wondering whether you should try these browsers, here’s my answer: don’t. Keep your banking, work, and personal accounts far away from AI browsers. Use them as a test environment if you must, but treat them like what they are. A privacy disaster waiting to happen.
"You don’t need an AI assistant watching everything you do online. You need a browser that respects your privacy and a phone that doesn’t report back to google."

I went to EFF (https://www.eff.org) but didn't find anything about testing Atlas. I guess they haven't written it up, but a Brave search (https://search.brave.com/search?q=EFF+tested+OpenAI+Atlas+browser&summary=1) found numerous articles about it.
I haven't gotten into enhanced privacy either, but Private Phone Shop offers both what look to be good devices (with Linuxes installed) and lots of helpful information.
