User reviews
Pros
- Allows annotation directly on webpages and PDFs, integrating well with tools like Obsidian.
- Offers powerful search and knowledge management features enhancing productivity and personal knowledge management (PKM) workflows.
- Continuously improving with frequent updates adding useful features like academic citations and PDF reading.
- Provides offline-first data storage, keeping data on user's device and maintaining privacy.
- Includes helpful support resources such as tutorials and good developer responsiveness.
Cons
- The removal of the full-text history search indexing previously visited pages greatly diminished core functionality.
- Significant bugs and instability, including crashes, buggy search (especially with special characters and CJK characters), and unreliable import/export features.
- Lack of user account deletion capability and unresponsive support for account removal requests undermining user trust.
- User interface issues like intrusive widgets (e.g., YouTube widget) that cannot be closed and a confusing or buggy UI experience.
- Shift from open source to closed source and introduction of paid plans with no upfront mention, causing dissatisfaction among users invested in the tool.
Recent reviews
No mention of a paid service up front and their airtable questionnaire doesn't even work when you uninstall. Doesn't look like it will be around long.

Please do not install this extension under any circumstances.
Once you install it and create a login account, you cannot delete the account.
You can send an email to request to delete your account from the app, but there is no reply.
There is a chat function and the developer is online, but there is no response when you request to delete your account.

Highly recommended. Everything and more than what I was hoping for. It hasn't been "very buggy" for me. It's working wonders with my PKM flow and the Youtube features are a game changer for my productivity. It's still in beta and the dev seems to respond quickly here. Hopefully the complainers don't undermine a noble effort and ruin it for the rest of us.

Extension safety
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk
impact extension cannot do much harms, whereas a high risk impact extension can do a lot of
damage like stealing your password, bypassing your security settings, and accessing your
personal data. High risk impact extensions are not necessarily malicious. However, if they
do turn malicious, they can be very harmful.
Memex requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Chrome extension may turn malicious.
This is determined by the publisher and the Chrome extension reputation on
Chrome Web Store, the amount of time the Chrome extension has been
around, and other signals about the
Chrome extension. Our algorithms are not perfect, and are subject to change
as we discover new ways to detect malicious extensions. We recommend that you always
exercise caution when installing a Chrome extension.
Memex has earned a fairly good reputation and likely can be trusted.
