Tooltivity is a browser-extension discovery and comparison platform that helps people find tools for work, learning, and everyday browsing. It covers extensions across 29 categories, including productivity, education, writing, note-taking, AI, privacy, and language learning, and supports comparisons across seven browsers, including Chrome, Firefox, Safari, Edge, Opera, Brave, and Vivaldi.

Rather than relying on store listings, Tooltivity says its team installs, uses, and scores extensions across six dimensions. Its directory includes 209 tested extensions, with reviews, category rankings, browser information, and recommendations for particular tasks. Scores are revisited about every two months. Visitors can search the directory, compare tools, and explore guides and editorial content.

Tooltivity also offers extension makers ways to submit products and participate in partner placements. It distinguishes paid promotion from editorial ratings: sponsorships and featured positions do not change an extension’s score, while a free verification label identifies developers who actively maintain their extensions and display Tooltivity’s testing badge. This approach combines product discovery with transparent, hands-on reviews.
