What It Is

Not So Fast is a Chrome extension positioned as a personal productivity tool that turns “procrastination” into “productivity.” It is not a traditional enterprise SaaS product; instead, before users visit distracting sites such as Facebook, it forces them to complete a quiz. Only after answering the required number of questions can they continue to the target website.

Core Features and Workflow

Based on the captured content, its core workflow consists of three steps: add blocked sites, where you put time-wasting websites onto a block list; choose a question bank, either using the product’s built-in question sets or uploading your own; and set the number of questions required before access is granted. This mechanism combines website blocking with knowledge review, making it suitable for fragmented learning scenarios such as vocabulary memorization, exam prep, and concept review.

Pricing, Trial, and Deployment

The page only provides an “Add To Chrome” button and does not disclose its pricing model, plans, free-tier limitations, or trial policy. Payment methods are also not mentioned. In terms of deployment, it is known to be a Chrome browser extension; the main text does not mention cloud accounts, mobile apps, self-hosting, desktop clients, or support for other browsers.

Collaboration, Integrations, and Security

Based on the available text, Not So Fast appears to be more of an individual tool than a team-oriented product. There is no mention of common enterprise software features such as team collaboration, member permissions, an admin console, third-party integrations, APIs, or developer documentation. Data security and compliance details are also not disclosed—for example, whether question banks are stored locally, uploaded to a server, or whether browsing history is collected. Organizations or schools should therefore verify its privacy and data-handling practices before using it at scale.

Pros, Cons, and Best-Fit Users

Its advantages are a straightforward concept, simple setup, and support for custom question banks, turning the hesitation before opening distracting websites into a learning trigger. Its drawbacks are that public information is very limited, the feature scope is relatively narrow, and there is no clear mention of cross-device sync, analytics, permission management, or similar capabilities. It is best suited to individual students, self-learners, exam candidates, and users who want to reduce time spent on social or entertainment websites.

Access from China and Alternatives

Access from mainland China is unknown; the Chrome Web Store itself may be unstable or difficult to access in domestic network environments, so the installation experience needs to be tested in practice. Possible alternatives include StayFocusd, LeechBlock, Cold Turkey, Freedom, Forest, or local Pomodoro/site-blocking tools, though they may not offer the same “answer questions before access” mechanism.
