The YouTube Chrome extension market is bigger and noisier than most creators realise. VidIQ and TubeBuddy dominate the top search results — but they're not the only options, and they're not always the best ones for your specific stage of growth.
We ranked 7 YouTube Chrome extensions in 2026 based on verified ratings, publicly available pricing, and what each extension actually does when you open YouTube. No affiliate arrangements changed the rankings.
How We Ranked These Extensions
Each extension was evaluated on four criteria:
- Free plan quality: What can you do without spending anything?
- Feature depth: Does it cover analytics, AI tools, keyword research, and competitor intelligence — or just one of these?
- Browser performance: Does it slow down YouTube?
- Trust and ratings: Chrome Web Store ratings, Trustpilot scores, and user review themes.
#1: VidIQ — Best Overall for Most Creators
Chrome Web Store: 4.5/5 from 10,900+ ratings · Users: 3M+ · Trustpilot: 4.3/5 (1,210+ reviews)
VidIQ is the market leader for a reason. Its free plan gives you 150 AI credits per month, keyword research, niche trend ideas, views-per-hour overlays, and the AI Coach — a conversational AI tool that reads your channel's data and gives you specific growth recommendations. At $19/month (Boost), you get 2,000 AI credits per month and full competitor intelligence. At $39/month (Max), 6,000 credits and unlimited trend research.
Pros
- Best all-round free plan in the category
- AI Coach is genuinely useful
- Views-per-hour overlay
- Strong keyword research tools
- Most reviews and validation
Cons
- Browser slowdown on mid-range devices
- Paid plans more expensive than TubeBuddy
- No A/B testing at any price
- Interface can overwhelm beginners
- 150 credits/month runs out quickly
Best for: Creators who want the most complete free YouTube intelligence tool. Also see: Best Free VidIQ Alternatives
#2: TubeBuddy — Best for A/B Testing
Capterra: 4.6/5 · Trustpilot: 3.5/5 (550+ reviews)
TubeBuddy's defining feature — A/B testing for titles and thumbnails — is unique in the market. No other extension lets you run split tests on YouTube to find out which title gets more clicks. The free plan covers keyword research, tag suggestions, and basic SEO audits. Pro ($9/month) unlocks A/B testing. Legend ($49/month) adds bulk video updates and deeper analytics.
Pros
- Only tool with A/B title/thumbnail testing
- Most affordable paid entry ($9/mo)
- Good free keyword research
- Bulk processing for established channels
Cons
- Trustpilot 3.5/5 — lower than VidIQ
- Browser slowdown reports
- Cluttered interface
- Poor customer support reviews
- No AI tools in free tier
Best for: Creators with existing videos who want to optimise performance through split testing. See: Best Free TubeBuddy Alternatives
#3: OutlierKit — Best for Competitor Research
Chrome Web Store: 4.9/5
OutlierKit overlays a performance multiplier on every video in a channel's uploads grid — instantly showing you which videos outperformed the channel average and by how much (e.g. "6.1×"). This is free, no account required. The extension is lightweight and doesn't slow down YouTube. The web platform includes deeper competitor analysis, idea tracking, and niche scoring — but requires a paid plan after 10 credits.
Pros
- 4.9/5 Chrome Web Store
- Free, no account needed
- Fastest way to spot outlier videos
- Lightweight — no slowdown
Cons
- Extension does one thing
- No keyword or SEO tools
- No AI writing
- Web platform expensive at $29–$199/mo
#4: Teka Creator Tools — Best All-in-One on a Free Plan
Teka Creator Tools is a Chrome extension that brings competitor analysis, AI title and script generation, score overlays, and a Channel AI Coach together in a single extension that works inside YouTube. The free plan doesn't cap you at 150 credits — you get the core AI tools included, with the higher-volume AI features on Pro and Pro Max plans. Currently in early access. Join the waitlist →
Features across plans:
- Free: AI title generator, keyword research, score overlays while browsing, basic analytics
- Pro (R99/mo): Unlimited AI titles, AI scripts, Beat This Video competitor deep-dives, Best Time to Post
- Pro Max (R299/mo): Success Probability scores, Shorts optimisation, multi-channel analysis
- Studio (R499/mo): Shorts video generation, team collaboration, API access
Pros
- Free plan with real AI tools
- Works inside YouTube — no tab switching
- Channel AI Coach gives clear next steps
- Shorts generation on Studio plan
Cons
- Currently waitlist only
- New — less historical data
- No A/B testing
#5: Thumbnail Test — Best Single-Purpose Tool
Thumbnail Test lets you upload a thumbnail and run real consumer polls to see which design wins before publishing. Unlike TubeBuddy's A/B testing (which tests on live traffic), Thumbnail Test works before you publish. The extension shows your thumbnail alongside competitor videos for a visual contrast check. A focused alternative if thumbnails are your specific weak spot.
Pros
- Pre-publish thumbnail testing
- Real human panel feedback
- Lightweight browser extension
Cons
- One feature only
- Paid plans required for real volume
- Not integrated with other tools
#6: Keywords Everywhere — Best for Keyword Research Only
Keywords Everywhere is a browser extension that overlays search volume data on Google, YouTube, and dozens of other sites. Rather than a subscription, it uses a credit system — $10 buys 100,000 credits. For keyword research on a tight budget it's extremely cost-effective. No AI tools, no analytics, no competitor features — purely keyword data.
Pros
- Very affordable pay-as-you-go
- Works on YouTube search pages
- Simple, lightweight
Cons
- Keyword data only
- No YouTube-specific intelligence
- No free plan
#7: Subscribr.ai — Best for AI Scripts (Web-Based)
Subscribr is a web app (not a Chrome extension) that generates video scripts by analysing high-performing videos in your niche. Rated 4.9/5 on AppSumo. It doesn't work inside YouTube and has no keyword research or analytics — it's purely a scripting tool. Ranked last here because it's not a Chrome extension and has no free plan. But if scripting is your specific bottleneck, it's the best specialised option.
Pros
- Scripts tuned to retention patterns
- 4.9/5 user satisfaction
- Good voice customisation
Cons
- Not a Chrome extension
- No free plan
- No analytics or keyword tools

Which One Should You Use?
There's no single right answer — the best extension depends on where you are as a creator:
- Just starting out (0–1,000 subs): VidIQ free + OutlierKit free. Cover AI basics and competitor research at zero cost.
- Growing channel (1K–10K subs): VidIQ Boost ($19/mo) for full AI tools, or TubeBuddy Pro ($9/mo) if A/B testing is your priority.
- Established creator (10K+ subs): TubeBuddy Legend ($49/mo) for bulk tools + split testing, or Teka Creator Tools Pro Max for AI-first workflow.
- Want one tool to rule them all: Join the Teka Creator Tools waitlist — it's the only extension building toward a unified free plan with AI, analytics, and competitor research.
Our recommendation for most creators in 2026: Start with VidIQ free and OutlierKit free. If you hit the limits of VidIQ's 150 monthly AI credits, either upgrade to VidIQ Boost ($19/mo) or switch to Teka Creator Tools when it's out of waitlist — whichever works better for your budget and workflow.
