Cortex
Everything in the box
A full browser — plus the parts the big ones forgot. 60+ features, zero data harvesting.
Your life, in context groups
Development, Productivity, Gaming, Entertainment — plus any context you create. Each holds its own tabs, its own quick-launch software (Google Docs, Office, VS Code Web, GitHub…), its own rules. Switch with one click or Ctrl+1–4; everything you left suspends to near-zero memory.
Tabs that behave
Suspension that keeps back/forward history
Reclaim memory without losing your place — back and forward still work after a tab wakes back up.
Smart exemptions: unsaved forms, playing audio never suspend
Cortex knows the difference between an idle tab and one you're mid-task in, and leaves the second alone.
Crash recovery with auto-reload escalation
A tab that crashes reloads itself automatically, backing off if the page keeps failing.
Send Tab to [context] — no re-login
Hand a tab off to another context in one step, session and cookies intact.
Pin, drag, mute, zoom, find-in-page
The everyday tab controls you already rely on, all still here.
Instant startup — session restores suspended
Cortex opens fast because it doesn't reload every tab at once — everything comes back suspended, ready when you click it.
AI, on your terms
100% OPT-INDon't want AI in your browser? Don't turn it on. Want it? Bring your own provider — or run it fully local.

Cortex never fills a field without you choosing to.
