4 distractions hidden. A calm feed is the tool working — toggle OnTask to compare.

One engine, three surfaces

It judges relevance once, then applies it everywhere the web fights back.

A bundled model scores content against your task on your machine; Groq weighs in on the close calls. That one judgment drives three things.

surface 01 — feeds

Off-task recommendations disappear

On YouTube, Reddit, search results — anywhere a feed tries to redirect you, off-task cards are hidden. If nothing qualifies, the panel goes calmly empty. That's the point.

surface 02 — navigation

Off-task jumps get bounced back

Wander to an unrelated site or search, and OnTask returns you to what you were working on. Sign-ins and legitimately-related pages always pass — it reads intent, not just domains.

On-task picks appear where noise used to be

Instead of just leaving a gap, OnTask fills a distracting feed with real, task-relevant results — turning the moment you'd have lost into a way back into the work.

What's inside

Focus tools that stay out of the way until you need them.

∿

Local-first relevance

A bundled embedding model decides most things on-device in milliseconds. Groq only weighs in on genuine close calls.

◎

Learns as you go

Every judgment the AI makes is remembered for the session, so similar distractions get filtered instantly — and faster over time.

◔

Focus timer & pause

Track real time on task, take an honest break, and pick up unfinished work next session — nothing lost.

▤

Session recap

See where your attention went: time in focus, distractions filtered, tasks completed.

◨

Quiet pastel chrome

A calm sidebar with your pinned task, live subtask, and open tabs — designed to fade into your work.

Never bricks the web

If the engine can't run, OnTask degrades to a normal browser. It protects your focus; it never traps you.

Most of it never leaves your machine.

The model runs on your device. To judge a close call, OnTask sends only the task and the text being checked to Groq — never your browsing history. No ads, no tracking, no telemetry. Your API key is stored encrypted, locally.
