If you run a YouTube channel, you already know — comments aren’t just “nice to have.” They’re the currency of engagement. They push your videos higher in YouTube’s algorithm, make your channel look alive, and create that sense of community everyone talks about.The problem? Coming up with relevant, natural, and non-spammy comments takes time. And if you’re running multiple channels or managing client accounts, that time adds up fast.That’s where a comment generator for YouTube comes in. The right tool can pump out engaging, human-like comments in seconds, freeing you up to focus on the stuff that actually grows your channel — like producing videos and optimizing your content strategy.In this guide, we’re going to:<ol><li data-list="bullet">Show you the best genuinely free comment generators for YouTube</li><li data-list="bullet">Flag the ones that look free but come with limits</li><li data-list="bullet">Share pro tips on how to use them without looking like a bot</li><li data-list="bullet">Drop in some extra tools from our <a href="https://aijourney.so/ai-academy/41-top-content-creation-tools-software-in-2024" rel="noopener noreferrer" target="_blank">AI Academy</a> that can take your YouTube workflow to the next level</li></ol>Let’s dive in.<h2>The Genuinely Free Comment Generators for YouTube</h2>When we say “free,” we’re talking about tools that actually let you generate useful comments without hiding the good stuff behind a paywall or a tiny monthly credit limit.<h3>1. Postiz AI YouTube Comment Generator</h3>If you want simple and effective, Postiz is a solid starting point. It’s 100% free, no sneaky upsells, and it’s built to churn out realistic, engaging comments fast.You give it your video’s topic or a keyword, and it spits out suggestions that sound like they came from an actual human — not a machine. This makes it ideal for creators who want to speed up audience interaction without risking spam flags.Fun fact: Postiz is also an open-source social media scheduler, so if you’re juggling multiple platforms, it can help you keep content organized.<img src="https://aijourney-store.s3.amazonaws.com/command/images/content/2025-08-08/1754632856221-postiz-free-ai-comment-generator-for-youtube.PNG"><h3>2. TubePilot’s Fake YouTube Comment Generator</h3>This one’s a bit different. TubePilot is free, but it’s mainly for mock-ups, not live interaction. You can customize comment text, likes, and usernames, then download an image that looks exactly like a YouTube comment section.It’s perfect if you’re making a presentation, building a YouTube tutorial, or creating promo material — but don’t expect it to actually post comments for you.<img src="https://aijourney-store.s3.amazonaws.com/command/images/content/2025-08-08/1754632961661-fake-youtube-comment-generator-free.PNG"><h3>3. AIFreeBox Free AI YouTube Comment Generator</h3>For unlimited comment generation, AIFreeBox is the clear winner. It’s completely free, doesn’t require sign-up, and lets you generate as many comments as you want.Key features:<ol><li data-list="bullet">Multiple tones: Humorous, Formal, Casual, Professional</li><li data-list="bullet">27 language options for global engagement</li><li data-list="bullet">SEO-friendly comment suggestions to help with discoverability</li><li data-list="bullet">Human-like phrasing to avoid spam detection</li></ol>The workflow is simple: enter your topic or keywords, choose tone and language, set creativity level, hit generate, and you’ll get 3–5 polished comments in seconds.Pro tip: Pair AIFreeBox with a YouTube keyword research tool like <a href="https://aijourney.so/tool/ahrefs-content-explorer" rel="noopener noreferrer" target="_blank">Ahrefs Content Explorer</a> to find high-impact keywords for your comment strategy.<img src="https://aijourney-store.s3.amazonaws.com/command/images/content/2025-08-08/1754633050205-aifreebox-comment-generator-for-youtube.PNG"><h3>4. Trickle’s YouTube Comment Generator</h3>Trickle offers a polished, free AI tool that produces comments tailored to your video’s tone and topic. You can pick from styles like enthusiastic, professional, casual, witty, or supportive.This makes it perfect for networking with other creators or adding thoughtful comments to videos in your niche. It’s about starting real conversations, not just dropping generic “Nice video!” replies.<h2>The “Free But Limited” Comment Generators</h2>Some tools say they’re free… until you hit a wall. These can still be worth using if you only need a few comments here and there.<h3>1. AI4Chat’s YouTube Comment Generator</h3>They advertise as “100% free, no login required,” but the reality is they run on a credit system. You get a set number of credits per month, and each comment costs one.On the plus side, AI4Chat uses advanced models like GPT-4 and Google Bard, so the quality is high. On the downside, heavy users will run out of credits fast unless they upgrade.<h3>2. EasyComment.ai’s Fake YouTube Comment Generator</h3>Like TubePilot, this one’s for visual mock-ups, not real engagement. You can customize every detail, including nested comments and like counts, then download a clean HD screenshot.If you’re creating YouTube tutorials or need fake comment sections for design work, it’s a great fit. But for growing your actual channel? Not so much.<h3>3. Comment Picker’s Comment Generator [AI]</h3>Comment Picker is best known for its giveaway tools, and while it does have a “comment generator,” the free plan is capped — max 200 comments unless you go premium.The comment generator function is a nice add-on, but unless you’re also running contests, it’s not the most efficient option.<h2>How to Actually Use a Comment Generator for YouTube Without Looking Spammy</h2>Here’s the big secret: AI comment generators are starting points, not final drafts. If you copy-paste everything without tweaking, you’ll stand out for the wrong reasons.Do this instead:<ol><li data-list="ordered">Edit for tone – Match your brand’s personality or the creator’s style.</li><li data-list="ordered">Add context – Reference something specific in the video so it feels genuine.</li><li data-list="ordered">Include keywords naturally – Helps with discoverability without looking forced.</li><li data-list="ordered">Mix AI with manual comments – Keep a balance so your activity looks authentic.</li></ol>And if you want to go deeper into AI-powered content strategies, check out our guide on <a href="https://aijourney.so/ai-academy/41-top-content-creation-tools-software-in-2024" rel="noopener noreferrer" target="_blank">41 Top Content Creation Tools</a>.
