Block distracting websites. Stay with the page that matters.
Opening a document is easy. Staying with it when another tab is a click away is harder. ContextFlow combines a scheduled website blocker with a focus lock for the page you want to finish.
Install for ChromeChoose what to block and when
Create a list of distracting sites in the extension settings. Apply a recurring schedule, an always-on rule, or a daily time limit. This works well when the same websites interrupt your work each day.
Lock into one tab or an entire website
Start a focus session on the page you are reading. Choose a single page for a long article, or a website scope when you need to move between documentation pages. Set a time or supported completion condition for the session.
Choose the amount of friction you need
Gentle mode presents a reminder when you leave the session. Strict mode brings you back to the locked page. A deliberate emergency exit is available; the extension cannot prevent closing the browser or using another device.
Read and ask questions without switching tasks
The focus lock works alongside the reading Navigator and in-page AI panel. Keep the original article open while highlighting the next sentence or asking your connected AI provider to explain a difficult paragraph.
