Let Derail block the brainrot

Derail is an AI focus agent that helps you filter out distractions in real time

Tell Derail your goal for today

Describe your goal in detail—and let Derail save your attention span by blocking sites unaligned with your goal. As an example, if you're learning math, youtube videos of dogs will be blocked but math lectures will be allowed through.

Personalize your Focus Agent

Finetune the blocking prompt to your needs. You can also add whitelisted or blacklisted sites.

Example of a site being blocked while a study video is allowed

Schedule recurring block sessions
