They overlap less than the feature lists suggest. One is a keyword-and-ideas suite with an AI layer; the other scores what videos actually did. Here is the honest split.
vidIQ is a broad YouTube suite: keyword research, daily video ideas, an AI coach, thumbnail generation, Shorts clipping. Its free tier is a taster; the useful volume sits behind a subscription with a monthly AI-credit allowance.
VideoCore Lens is narrower on purpose. It answers one question everywhere you browse YouTube — did this video actually do well, and for whom? — by scoring every video against its own channel's recent uploads. It is free with no credit allowance, and shows no score at all where the data does not support one.
If you want keyword volumes and a daily idea feed, vidIQ does more. If you want to know which videos in your niche genuinely broke out and why, without a meter running, that is what Lens is for. Plenty of people run both.
| vidIQ | VideoCore Lens | |
|---|---|---|
| Free tier | Yes — limited keyword results, a few daily ideas, and a monthly AI-credit allowance that the AI features draw down | Yes — scores on every video, every time. No credits, no daily cap |
| Paid | Several tiers, roughly $7–$49/month depending on plan and billing period, plus a separate coaching add-on | No paid tier for the extension. VideoCore's platform has paid plans; the extension is not one of them |
| Account needed? | Yes, to use it | No — scores work signed out. A free account adds the AI coach and saving to your workspace |
Prices checked September 2026 and simplified to bands on purpose — vidIQ changes tiers and runs promotions, so treat this as a shape, not a quote, and check their pricing page for today's figure.
Worth saying plainly, because a comparison that gives the other tool nothing is not a comparison:
This is the one that matters, and it is worth understanding before you trust any tool in this category.
YouTube does not publish impressions, click-through rate, watch time or retention for videos you do not own. They exist only in the owner's YouTube Studio. That means no third-party tool can measure a competitor's CTR — anything shown is inferred. The same goes for "SEO scores" and keyword search volumes: YouTube publishes no search-volume figure, so those numbers are models, and different tools confidently disagree with each other about the same video.
Estimates are not worthless. A clearly-labelled range is a reasonable planning tool. The problem is an estimate formatted to look like a measurement — a number out of 100, a letter grade — because people make real decisions on it.
Lens shows only what it counted. Views, likes, comments, engagement rate, views per hour measured from tracked history, and a multiplier that is nothing more than views divided by the median of comparable uploads. Where we estimate — an earnings range, a straight-line projection — it is shown as a range and labelled as an estimate. We removed our own AI packaging score from the panel in September 2026 for exactly this reason.
Yes, and a lot of people should. They sit in different places: vidIQ is strongest when you are planning a video, Lens is strongest when you are looking at videos that already exist. Both are Chrome extensions and both have free tiers, so the honest way to decide is to install both and see which one you actually open.
One practical note: several extensions inject panels into the same right-hand column on a watch page, so with a few installed you will be scrolling. That is worth knowing before you add a fourth.
No account needed for the scores, no credit allowance, no trial that expires. Install it and browse YouTube normally.
Get VideoCore Lens — free Or run a free channel audit firstPartly. Lens replaces the part of vidIQ that scores videos and channels on real performance data, and it does so free with no credit limits. It does not replace vidIQ's keyword research tools or its daily idea feed, which are deeper. Many creators run both.
Yes. Scores appear on every video with no account and no credit allowance. A free VideoCore account adds the AI coach and saving transcripts or videos into a workspace. The extension itself has no paid tier.
Yes, with limits: a small number of keyword results per search, a few daily ideas, and a monthly allowance of AI credits that the AI features draw down. When the credits run out those features stop until the allowance resets.
No. CTR requires impression data, which YouTube provides only to the channel that owns the video, inside YouTube Studio. Any third-party CTR figure for someone else's video is an estimate derived from assumptions, not a measured number.
Because the scores are models rather than measurements. YouTube publishes no keyword search volume and no impression data, so each tool infers them differently. Figures that come straight from YouTube - views, likes, comments, publish date - are the same everywhere.
Lens, as a matter of design: it shows a multiplier against the channel's own comparable recent uploads on every thumbnail as you browse, with filters for 2x and 5x on channel pages, and no cap on how many you can score. vidIQ surfaces outlier-style data too, within its plan limits.
No, they run side by side. Be aware that several extensions inject panels into the same right-hand column on a watch page, so having several installed means more scrolling.
