Dex by Thirdlayer

Dex reads the page you're on and understands what you're trying to do, then offers help in place instead of making you switch to a separate chat window. It works like a Chrome AI assistant that suggests context as you browse. You spend less time hunting for the right tab.

The extension connects with apps you already use and acts across them to cut context switching. This is the AI workflow automation piece. You can turn a multi-step process, like logging a conversation into a CRM, into a single action that runs in the background.

Everything Dex learns from your corrections, approvals, and edits builds into a knowledge base that belongs to you. The more you use it, the sharper its suggestions get. It compounds your decisions instead of starting fresh each time. That matters. Most copilots forget you the moment a session ends.

Automations and background agents keep working even when you're focused elsewhere. You don't babysit them. Higher tiers add advanced agent scheduling, so recurring tasks run on their own timeline without you kicking them off. What does that look like in practice? You set a task once, and it keeps running while you get on with your day.

Dex syncs your connected apps into one context layer. The Core plan includes three integrations, Max raises that to five, and Ultra allows up to fifteen. Teams get a shared operational graph on top of that. More connections mean more of your work lives in one place.

Data is encrypted at rest and in transit with 256-bit encryption, and Thirdlayer monitors its dependencies and cloud infrastructure for vulnerabilities. You own everything. You can export, delete, or disconnect your data anytime, and browser memory is off by default. That last point matters if you handle sensitive client work.

Teams that need tighter isolation can run Dex on their own infrastructure. The enterprise track adds private cloud deployment, data isolation, and dedicated engineering support for larger rollouts.
