The first focus tool that reacts to your task
Other blockers make you build lists. Envelop reads your task and builds the perfect focus environment — blocking what's distracting, keeping what's useful.
Type your task, we do the rest
Enter "Write Q4 report" and Envelop automatically suggests blocking Google Docs distractions, social media, and news sites—while keeping research tools accessible.
Context-aware blocking
Working on code? Slack stays blocked, but Stack Overflow is allowed. Designing? Pinterest is fine, but Twitter isn't. Your focus session adapts to your work.
You always have the final say
AI suggests what to block based on your task, but you review and approve everything before diving in. Add or remove apps and websites with one click.
Why this works: You don't have to predict what will distract you. Reactive Focus Sessions learn your work patterns and build the perfect focus environment in seconds.
One click. Clean slate.
Hit dive and watch your desktop transform into a distraction-free workspace.
Distracting apps close automatically, and stay blocked.
Blocked websites vanish across every browser.
Brown noise fills the silence so your brain stops wandering.

Your entire environment shifts to focus mode — in seconds.
Everything you need to stay locked in
Not willpower hacks. Real tools that remove distractions and keep you in the zone.
Reactive Focus Sessions
Type what you're working on. Envelop intelligently suggests which apps and sites to block based on your task. No decision fatigue configuring blocklists.
Session Todo Lists
Each session gets its own task list. Break work into steps, check them off as you go, and merge leftovers into your next session. Stay on track without losing context.
Brown Noise Immersion
Built-in audio scientifically shown to improve focus. Tune out background noise and quiet the mental chatter so you can lock in.

Pomodoro Built-In
Work in focused bursts with built-in breaks. Customize work and break lengths to match your rhythm. Short sprints, not marathons.
Streaks & Celebrations
