Hey Product Hunt! Regina here, cofounder of ThirdLayer 👋

Got 100+ tabs open? Yeah, we did too.

The problem: Knowledge work requires deep context - your preferences, relationships, and knowledge. Every AI tool gets it wrong because they can't adapt to your unique situation - so we built our own.

Dex turns your browser into an AI workspace that knows you. As a founder and the #1 power user, it's saved me countless hours and entirely removed copy-pasting, organizing to-dos, and manual actions from my workflow.

Here's what makes Dex different:

Get to Tab Zero: Inbox zero, but for tabs. Check out our onboarding tomorrow for a surprise ;)
Actions Anywhere. Connects dozens of power apps and acts across all your tabs. Find anything instantly from calendar + slack + linear, scrape complex sites into sheets, draft mass personalized emails, + so much more. All in a few seconds without leaving your tab.
Proactive Scheduling. Surfaces what you need before you ask - Dex checks your availability the moment scheduling appears and creates calendar invites for you.
Automatic Email Drafts. My favorite! Every morning, Dex pings me with important emails and pre-drafts the perfect response with all the relevant context already pulled in.
Workflow Memory. Our agentic memory system learns from every interaction. Teach Dex once, never repeat yourself again. Use your daily work diary as a personal knowledge-base & productivity metrics.

Other important notes:

Privacy focused. Secure OAuth. We never train on your data. You control everything from incognito chat to specific domain and history settings.
Zero adoption cost. No new browser or app needed. Dex works on top of what you already use.
Always confirm mission-critical actions. We've built our system around providing you maximum confidence in AI: before editing, deleting, or sending, we ask for one-click confirmation.

Since YC, we've scaled to thousands in closed beta. Today we're opening it up to get your feedback.

Launch special: 500K free tokens + code DEX for $5 off Pro

Dex is built by ex-founders, quant researchers, designers and engineers from Meta FAIR, Jump Trading, and Harvard. Backed by YC and leading deep tech investors. Huge shoutout to Chris Messina (#1 Hunter!) and Michael Siebel for their support!
