vidIQ and CommentShark get compared a lot, and the comparison is a little unfair to both, because they're solving different problems. vidIQ helps you decide what to make and how to package it; CommentShark handles the conversation underneath the video once it's live. We build CommentShark, so factor that in, but the vidIQ facts below come from its own plans page and help docs, checked July 2026, and vidIQ is genuinely excellent at what it does.
Short answer. vidIQ is a research and growth powerhouse (keyword tools, outlier hunting, an AI coach) with a generous free plan and only a footnote of comment capability, and it never takes actions on your channel. CommentShark is the opposite: a narrow tool that replies, moderates, and triages your YouTube comments with AI-and-keyword rules and an approval queue.
At a glance (checked July 2026)
The single most important row is the last one: vidIQ, by its own stated policy, never makes changes to your YouTube channel. That one design choice rules out the entire action side of comment management, and it's why the two tools slot together rather than compete.
Where vidIQ genuinely wins
vidIQ is TubeBuddy's closest rival and, for research, arguably the stronger product. Keyword and competitor tools, outlier hunting, best-time-to-post, thumbnail and title generators, a channel audit, and an AI Coach grounded in your channel's actual data: that's a deep growth stack nothing comment-focused touches. Per its plans page, paid tiers start at $19/month for Boost ($16.58/month on yearly billing), and the free plan is genuinely useful with 150 monthly AI credits and no credit card. If your priority is figuring out what to make next and how to package it, vidIQ earns its place and CommentShark doesn't try to compete there.
Why vidIQ can't manage your comment section
Comments are a footnote in vidIQ, and that's not an oversight, it's the product's stance. There are zero mentions of comment management on vidIQ's current features page, and its help docs describe the extension's Comment Tool in a single sentence, that it lets you "save time and filter the comments." Its credits table confirms a "Comments Replies" feature at one AI credit per generated reply, so there is an AI reply generator, but it works one comment at a time, with no vendor evidence of training on your voice, and vendor docs don't specify whether the reply is posted by vidIQ or pasted by you. The richer comment filters some blogs describe (by question, profanity, or sentiment) live only in vidIQ blog posts from 2013 to 2020 and can't be confirmed in the current product. Above all, vidIQ's own permissions documentation states it never makes changes to your YouTube channel, which means no deleting, no hiding, no moderating, and no rule-driven replies. It is a research tool that can draft the occasional reply, not a system that runs your comment section.
How CommentShark handles the action side
CommentShark is built around the exact thing vidIQ declines to do: take action on your comments, safely. Rules match by keyword, regex, or AI classification and can reply, hide, or delete around the clock across every video. AI replies come from your own reply history so they sound like you, and because the realistic fear with automation is that it posts something embarrassing, every rule can run in an approval queue where you approve drafts with one click before anything goes public, or autonomously once you trust it, a per-rule choice we explain in approval vs autonomous mode. The free plan includes 3 rules and 20 automated actions a month with AI, so pairing it with vidIQ's free plan gives you research and comment automation for $0 to start.
- Keep vidIQ for: keyword and competitor research, outliers, thumbnail and title generation, channel audits, and the AI Coach.
- Add CommentShark for: AI-and-keyword auto-replies in your voice, auto-moderation, an approval queue, and full-channel comment search.
- Pricing: both have real free plans; vidIQ paid from $19/month, CommentShark paid from $19/month. The rest of the category is in our full tool comparison.
