Jublu

A website blocker that doesn't just block. Jublu replaces blocked pages with personalized, escalating messages that fit the moment, so you actually stop instead of reopening the tab. Block on your phone, blocked in Chrome, same account. Hostname-only, no page reading.

The Chrome extension is included with Jublu Plus. If you already subscribe through the Jublu Android app, sign in with the same Google account and your blocking groups sync to Chrome. New here? Start a free trial in the Android app, then install this extension to block the same sites in Chrome.

Most website blockers show a generic blocked screen, and a static page does not help you stay focused. You see the screen once, you click past it, and the distraction wins. Self-control runs out. Generic friction wears off.

Jublu replaces the blocked screen with a conversational message tailored to how often you have tried to open the site today. Three escalating tiers: a gentle reminder on attempt one, a more direct nudge after five, and a stop-and-reflect prompt after ten. The message engine draws from seven distinct conversational tones (Supportive, Empathetic, Encouraging, Curious, Grounding, Direct, Compassionate) and matches the tone to the moment, so the message lands in a way that fits.
