You enable the extension, open its popup, and submit one or more topic keywords — for example "gaming", "streaming" or "movie". From then on, when you browse, Concentration evaluates the sites you visit against those keywords and blocks the ones that fit. The extension offers two engines. Strict Mode relies on natural-language processing: it is fast but occasionally less precise. GPT Mode routes the same judgement through ChatGPT, which is slower but more accurate. You can switch between the two at any time, and you can remove keywords individually or reset the list entirely. Because the keywords are topical rather than tied to fixed domains, the blocker adapts to new and unfamiliar sites without any manual list maintenance. Concentration is free to use and, according to its Chrome Web Store listing, does not require a paid ChatGPT subscription. The listing (version 2.01, updated September 22, 2023) reports a 4.6-star average from about 20 ratings and roughly 228 users. The developer states that collected data on web history, user activity and website content is not sold to third parties. **Pricing & Plans:** Free. Concentration is offered at no charge and, per the Chrome Web Store listing, does not require a paid ChatGPT subscription to use its GPT Mode. - **Keyword-based blocking:** Enter topical keywords such as "gaming" or "movie" and the extension blocks pages that match them, so you never have to curate a fixed domain blocklist. - **NLP vs ChatGPT modes:** Switch between Strict Mode, which uses faster NLP classification, and GPT Mode, which uses ChatGPT for greater accuracy on ambiguous pages. - **Simple keyword management:** Submit keywords one at a time, remove them individually with an ✗ control, or wipe the whole list with a single Remove All action. - **No paid AI plan required:** The developer states you do not need a paid ChatGPT subscription to use the extension's ChatGPT-powered mode. - **Lightweight Chrome footprint:** The extension ships as a small ~1.5 MiB package that runs quietly in the background and is controlled from a popup. **Strengths:** Free with no required ChatGPT subscription; Keyword-based logic adapts to new sites without maintaining a blocklist; Two engines let you trade speed for accuracy; Very small download footprint (~1.5 MiB) **Limitations:** Last updated September 2023, so it does not track newer Chrome or GPT APIs; Small user base and only ~20 ratings, so reliability signals are thin; Keyword blocking can over-block legitimate pages that mention a topic [Profile (Markdown)](https://openaitools.app/tool/concentration.md) ## Molla Most site blockers treat every distraction the same: they simply cut you off. Molla takes a different approach by first asking what you actually want to achieve — both for the year ahead and for the day in front of you. With those goals in hand, it acts as an intelligent accountability partner that watches where your browsing is heading and intervenes when the destination does not match your intentions. Instead of a hard wall, Molla uses smart redirection. Because it understands your objectives, it can let you keep using content that genuinely helps you progress, while nudging you away from pages that quietly eat your time. Setting Molla as your Chrome new-tab page puts that checkpoint in front of you every time you open a tab, so the reminder and the guidance arrive exactly when you are about to drift. Molla also includes a conversational layer: you can talk to it about your goals and get practical support for following through. The result is a lightweight habit-building loop — state your intention, get redirected toward it, and check in when motivation dips. It is best suited to people who want gentle, goal-aware guidance rather than an all-or-nothing block list. **Pricing & Plans:** Molla is free to use. No paid tiers or public pricing page were found; you create an account to save your goals and settings. - **Goal-aware redirection:** Tell Molla what you want to achieve for the year and for today, then let it redirect you away from content that conflicts with those goals instead of blocking sites indiscriminately. - **Smart new-tab checkpoint:** Set Molla as your Chrome new-tab page so your goals and guidance appear every time you open a tab — exactly when distraction usually starts. - **Conversational goal coaching:** Chat with Molla about your objectives to get help, perspective, and nudges when you need support following through. - **Alignment instead of blanket blocking:** Content is judged by whether it supports your goals, so genuinely useful pages are not cut off alongside pure distractions. - **Account-based setup:** Sign in to store your goals and preferences so your accountability setup carries across sessions. **Strengths:** Encourages intentional browsing instead of blanket blocking; New-tab checkpoint places guidance exactly where distraction begins; Conversational goal support adds a coaching layer; Lightweight and free to use in Chrome **Limitations:** No public pricing page or roadmap details are available; Requires you to define goals honestly for redirection to be useful; Chrome new-tab dependency may not suit users of other browsers [Profile (Markdown)](https://openaitools.app/tool/molla.md) ## Frequently Asked Questions ### How do Concentration and Molla compare in monthly traffic?
