What is Concentration?
Concentration is a free Chrome extension built to help users stay focused during study or work by blocking distracting websites. It uses natural language processing and ChatGPT to identify websites related to keywords you enter, so it can block categories of distractions rather than only specific domains. The extension is positioned as an AI-powered focus tool that tries to reduce time spent on gaming, movies, and other attention-draining sites.
The setup is straightforward: enable the extension, open the popup, enter one or more keywords for the kinds of sites you want blocked, and submit them. You can remove keywords individually with the x control or clear everything with Remove All. The product is designed to continuously monitor your browsing and attempt to block sites that match the categories you define.
Concentration includes two operating modes: Strict Mode and GPT Mode. Strict Mode is described as NLP-based, faster, and less accurate, while GPT Mode is ChatGPT-based, slower, and more accurate. This gives users a basic tradeoff between speed and precision depending on how aggressively they want distractions filtered.
It is aimed at students, remote workers, and anyone who wants stronger browsing discipline without manually curating a huge block list. The website emphasizes that the extension is free for all and that users do not need to pay for ChatGPT to use it. It is best suited for people who want a lightweight, category-based blocking tool with AI-assisted classification rather than a traditional static blacklist.

Frequently asked questions about Concentration
What does Concentration do?

How do I set it up?
You enable the extension, open its popup page, enter one or more keywords that represent the categories you want blocked, and click Submit for each one. You can also delete a single keyword with the x control or wipe all keywords at once with Remove All.
Does it block exact websites or categories?
It is designed around keyword-based categories rather than only exact URLs. For example, you can enter terms like gaming or movie, and the extension will try to block websites that are relevant to those topics.
What is Strict Mode?
Strict Mode is the NLP-based operating mode. The listing says it is faster but less accurate than GPT Mode, so it appears to prioritize speed over precise classification when deciding what to block.
What is GPT Mode?
GPT Mode uses ChatGPT-based classification. The listing says it is slower but more accurate than Strict Mode, so it is meant for users who want stronger detection of distracting websites even if it takes a bit more time.

Can I remove keywords later?
Yes. You can remove keywords individually using the x next to each keyword or use Remove All to clear the full list of block keywords.
How does it decide what to block?
The extension uses natural language processing and ChatGPT to optimize performance and accuracy. After you enter keywords, it tries to block websites you visit that are relevant to those terms across your browsing experience.
