## Concentration

Concentration is a lightweight Chrome extension built around a simple idea: instead of maintaining a hand-written blocklist, you describe the kinds of sites you want to avoid and let AI decide which pages match. 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

## Focus AI

Focus AI targets a specific and familiar failure: most blockers are easy to switch off. The founder's first support email came from a student who kept disabling the extension through the Chrome puzzle-piece icon. That insight shapes the whole product, which sets out to make quitting annoying rather than merely discouraged.

The core mechanism is an AI classifier that evaluates each page against the task you typed at the start of a session. Rather than blocking youtube.com outright, it distinguishes contexts, letting a calculus lecture or a Google Doc through while rejecting Shorts, Reels and TikTok. Sessions run in 25, 45 or 60 minute blocks, and three blocking levels range from standard filtering to strict mode with no exit at all.

The second mechanism is the Quit Wall. There is no quit button to click; to end a session early you must type the phrase 'I am choosing to give up' letter by letter, with no pasting. A third element rewards the behavior you want: each time you resist a diversion it is logged as an urge surfed, and reclaimed minutes accumulate into a weekly tally. A persistent LOCKED IN badge sits on every page and blocked pages catch you when you drift. Setup takes about 30 seconds and requires no account. Focus AI is operated by IndieHacker Ventures Limited, registered in England and Wales, and the developer answers support email personally, often within a couple of hours.

**Pricing & Plans:** Free to install, with the first three focus sessions free. After that it costs $9.99 per month for people who have decided the exam or deadline is worth it. No account is needed to start.

- **Task-aware AI blocking:** The extension reads each page and judges it against the goal you typed, so work-related YouTube or Docs stays available while feeds and Shorts are refused.
- **The Quit Wall:** There is no one-click off switch. Ending a session early means typing a full surrender sentence by hand, letter by letter, with no pasting allowed.
- **Three strictness levels:** Pick standard filtering, the Quit Wall, or a nuclear mode with no exit at all, and escalate on days when your attention is fighting back.
- **Urge-surfing rewards:** Every time you choose work over the feed the moment is stamped and timed, and banked minutes build into a weekly record of reclaimed time.
- **Fast, account-free setup:** Around 30 seconds to install and start a first session in Chrome, with strict mode on by default and no sign-up required.

**Strengths:** The AI classifies by task context rather than domain, so legitimate work on YouTube or Google Docs is not blocked; The Quit Wall is genuinely hard to bypass, which is the point for people whose problem is impulsive disabling rather than lack of intent; About 30 seconds to set up, strict mode by default and no account required; Solo developer who answers support email personally and turns around fixes quickly, according to publicly visible reviews

**Limitations:** Chrome only for now, with a Mac version on a waitlist rather than shipping; The strict, high-friction design is a feature for its audience but will feel excessive to anyone wanting casual nudging; Free usage is limited to three sessions, so evaluating long-term fit requires paying $9.99 a month
