Concentration is a Chrome extension designed to improve your focus during study or work sessions by blocking distracting websites. It utilizes natural language processing (NLP) and ChatGPT to optimize performance and accuracy. You can input keywords representing categories of websites to block, such as gaming or movies. The extension provides two modes: Strict Mode, which is NLP-based and faster but less accurate, and GPT Mode, which is ChatGPT-based and slower but more accurate.
1) Enable the extension and open the popup interface. 2) Enter keywords for the website categories you wish to block (e.g., gaming, movie). 3) Click 'Submit' to add a keyword, or 'Remove All' to clear your list. You can also click the ✗ icon next to specific keywords to remove them individually. 4) Select your preferred setting: Strict Mode (NLP-based) or GPT Mode (ChatGPT-based). 5) The extension will automatically block websites that match your entered keywords.
Concentration blocks websites based on the keywords you provide. It uses either NLP (Strict Mode) or ChatGPT (GPT Mode) to analyze whether a website is relevant to your keywords and should be restricted.
Strict Mode uses NLP for faster blocking performance, though it may be less accurate. GPT Mode uses ChatGPT for more precise blocking, though it may operate more slowly.
Yes, Concentration is available for free to all users.
