What is ContextFlow?
ContextFlow is a Chrome extension that combines scheduled website blocking, tab focus locks, sentence-by-sentence reading, and an AI assistant that uses the current web page as context.
Can I use it without an account?
Yes. You can install ContextFlow and use its free local features without signing in or entering a credit card. An account connects supported history and settings across devices.
How is a focus lock different from a website blocker?
A website blocker restricts a list of distracting sites. A focus lock keeps you on one chosen page or website until your session conditions are met. A deliberate emergency exit remains available.
How does AI access work?
Connect a supported AI provider with your own API key in the extension settings. Your key stays on your device, and requests go directly to the provider you choose. Provider charges and plan limits are separate.
Does it work on every page?
ContextFlow works on supported web pages in Chrome. Browser-internal pages and the Chrome Web Store restrict extensions; some complex pages may not support every reading feature.
Ready to supercharge your focus?
Build a calmer reading workflow, one page and one focus session at a time.
