Paid keyword tools like Ahrefs, Semrush and Keywords Everywhere are powerful — but $99-$199/month is a hard sell when you just need volume and difficulty for a handful of queries. The Fulhar Keyword Research Chrome extension fixes that. Open YouTube or Google search and a side panel reveals search volume, competition, CPC, top-ranking keywords and long-tail variations — instantly, for every query you type.
Under 1MB, zero tracking, free forever. Works on YouTube search, Google search, and any page where you highlight a keyword. Most users keep it pinned to the toolbar as their daily SEO sidekick.

Frequently asked questions
Is the keyword research extension really free?
Yes. Unlimited keyword lookups, search volume, and long-tail suggestions on the free tier. No card, no signup, no daily caps. Heavy commercial use (10,000+ lookups/day) is on a paid tier.
How accurate is the search volume data?
We aggregate from multiple sources (Google Keyword Planner, YouTube autocomplete, click-stream data) and refresh monthly. Accuracy is within ±15% of Ahrefs/Semrush for most queries.
How is this different from Keywords Everywhere?
Keywords Everywhere requires a paid credit pack for most features. Fulhar's extension is free, covers YouTube + Google + Amazon, and includes competitor keyword spy — which Keywords Everywhere doesn't.
Does it work on YouTube?
Yes — full YouTube search volume, video tags, and competitor keyword data. Works on every Chromium browser.
Will my account be safe?
Yes. The extension only reads page content on YouTube/Google search pages (no API access, no OAuth, no account permissions). It can't post, modify, or delete anything anywhere.
Which browsers work?
Any Chromium browser: Chrome, Edge, Brave, Arc, Opera, Vivaldi. Firefox support is on the roadmap.
Do I need a Fulhar account?
No — all core features work without login. Sign in only if you want to save keyword lists or sync research across devices.
Is my browsing data tracked?
No. Zero telemetry, zero analytics scripts. The extension only sends the keyword you searched (not your URL or browsing history) to our API for volume lookup.
Ready to add to chrome?
Free to start. No credit card. Sign in only when you're ready to save your work.
