this has been the most exciting project to work on. a lot of foundational infra we've built over time (search engine, browsing cloud, memory engine, and more) all came together in one platform. this was also built by a small group of people and a lot of AI coding agents. testing, debugging, evals, development, all automated with AI. i've never seen such rapid iteration speed before, and i'm excited to see how fast we're going to make improvements over the next days and weeks. stay tuned!

Happy “best browser is now on iOS” Day to all who celebrate @comet sync was complicated to set up, but works great between desktop -> mobile

turning local Comet into a tool for Computer is a huge unlock, it enables an entire different dimension of things you can do with Computer. another important thing: this is fully local, your cookies are not going anywhere, and we made it to be extremely transparent for the user to see what is going on. you are in full control.
Perplexity@perplexity_ai

Computer can now take full control of Comet to complete tasks. When you’re in Comet, Computer spins up a browser agent that can access any site or logged‑in app with your permission, without the need for connectors or MCPs. Available to all Computer users on Comet.

@Aymen94Jelassi @denisyarats Not a tweet war. We've been emailing. They didn't read my email until after I posted, so we wanted to clarify our positions here and get to the facts. They've built a great product and at the same time there are security concerns that people building agents should watch out for.

Update: @denisyarats (Perplexity CTO) responded. He says billing is async and tied to the user's account, not Perplexity's master account. I want to be transparent about where I stand on this. I ran 400k+ output tokens through the extracted key with Opus 4.6 and checked my credits over 18 hours. They never moved. It's possible that's just a long reconciliation delay. What is not in dispute: the token extracted via .npmrc injection worked from my personal laptop outside the sandbox. A sandboxed credential shouldn't be usable from an arbitrary external IP. This also means it's a prompt injection target. a malicious webpage visited by the agent could plant the same payload + prompt, exfiltrate the user's token, and bill them for third-party API usage without their knowledge. The proxy pattern is the right architecture. Binding tokens to sandbox IDs and IPs would close the remaining gap. Appreciate Denis and the Perplexity team for the fast and transparent response.

@pelaseyed yes, each payload is being verified for a prompt injection

@denisyarats This is actually best practice for sandboxes. Are you still running the fine-tuned Qwen for detecting phishing etc.?

This isn’t accurate. The secure sandbox of Perplexity Computer creates a temporary proxy token for every user session. We choose not to hide it from the user because it’s their token. (They can do whatever they want with it, but I don’t recommend posting it on X) It’s not an API key, it’s a short-lived proxy token associated with the session and user. It’s located in the sandbox, because that’s the point of the sandbox. Anything run through it is billed back to your account. Billing is async, which may have caused this user’s confusion. Don’t worry, as soon as we saw this post we ensured this user’s session token was revoked for security. The session he describes generated 197 billing events. We shared billing details with him directly but can’t publicly. (Billing is done at the proxy, and every cost is attached to the proxy token.) Thank you @YousifAstar for creative security research and collaborative spirit. Everyone else - email is a slow way to reach us! We have a thriving VDP that helps keep all of our products secure. perplexity.ai/hub/security-v…

The cofounder and CTO of Perplexity, @denisyarats just said internally at Perplexity they’re moving away from MCPs and instead using APIs and CLIs 👀

We run the entire go-to-market with Perplexity Computer. I’ve had 3 exits and I spent years building real GTM teams. I know how much time, hiring, alignment, and iteration it takes to create a high-performing growth + sales machine that actually works together. With my new project, I’m testing a different approach - one that simply wasn’t available before. Context: @OpenMercato is an open-source framework for building enterprise applications using AI-assisted engineering (CRM, ERP, logistics, internal systems) designed to be production-ready from day one. We run the entire go-to-market with Perplexity Computer. Marketing It created a GTM strategy tailored to our actual traction (GitHub activity, early adopters, positioning) and continuously updates it. Every day it generates concrete marketing opportunities: content ideas, ready-to-post comments in my voice, real-time threads to join, conference CFP applications, newsletter pitches. It scans the entire industry landscape to detect new signals and trigger real-time marketing - when a topic trends, we’re already in the conversation. Sales On the sales side, it analyzes every single lead: role, company size, industry, public footprint, context of the contact person - and suggests the best next action. It prepares contextual updates for ongoing deals, surfaces risks and leverage points, and turns onboarding emails into informed founder-led conversations. What used to require a growth + SDR + ops stack now runs as one autonomous system. Big Thanks to @AravSrinivas and to the Perplexity Team!

I'm using @perplexity_ai Computer to build my personal website from scratch. First step: I described the vibe I was going for (that "I'm powering up my first computer" feeling), and it put together this mood board — references, palette, layout direction. It's not just building for me. It's designing with me.

Ok, this is insane...🤯 I've just built the most comprehensive RAG system (UX Knowledge base) for me to use in my projects with @perplexity_ai . > Instant, research-backed best practices (548 items) for design > 10X the output quality for Project Aristotle with a grounded knowledge layer: project-aristotle.vercel.app > Ability to present design decisions to stakeholders with cited rationale and data. Data is the new oil. Already shared it with those who pre-purchased @AgenticUi in January as a token of appreciation for support.
