About chrome extensions and browser tools

27 of the 31 browser tools here have a free plan, and paid upgrades have a median listed price of $10/mo. The group mixes several jobs: writing assistants (Grammarly, QuillBot), bookmark and tab managers (Raindrop.io, Workona, Toby), a focus dashboard (Momentum), AI sidebars such as Sider.ai and Merlin, quick site checks (seo meta in 1 click for meta tags, Wappalyzer for detecting a site's technology) and shopping extensions (Honey, Rakuten). Because extensions can read the pages you visit, check permissions and data collection as carefully as price.

What to compare before you choose

Permissions and privacy

Extensions that can read every page can also collect browsing data. Our review flags Honey for privacy-conscious users because of its broad data collection, and for creators and affiliates because of commission attribution conflicts. Check the permissions each extension requests and how the vendor makes money.

Free tier limits

Most extensions are free to start, but limits differ: Workona's free plan covers 5 spaces before Pro at $7/mo, while Grammarly and QuillBot keep their fuller features for paid tiers from $12/mo and $8.33/mo on annual billing. Rakuten and seo meta in 1 click have no paid tiers at all.

Personal tool or team rollout

Many extensions are built for one person: Momentum is single-user only, and Raindrop.io lacks collaborative knowledge management. Grammarly is priced per seat, so team costs scale with headcount. If you need shared workspaces, check team plans before rolling an extension out company-wide.
