Hey Product Hunt 👋 I built CommentCanvas after noticing how much manual work goes into handling YouTube comments—scrolling endlessly, hunting for good ones, taking screenshots one by one, and still missing valuable audience feedback. What really stood out to me was that comments aren’t just something creators read once and forget. They’re signals: what people loved, what confused them, what they’re asking for next. But there wasn’t an easy way to both showcase comments visually and learn from them. So I started with a simple question: What if creators could treat comments like content and insights, not clutter? The product evolved from a basic comment snapshot idea into a workspace where creators can search, style, export comments—and now even see sentiment, questions, and emotional reactions at a glance. Throughout the build, I focused on keeping it lightweight, fast, and creator-friendly. I’d love to hear what you think, what features you’d want next, or how you currently work with comments. Thanks for checking it out 🙌

CommentCanvas makes engaging and organizing feedback around content much more intuitive — transforming comment threads into visual, contextual spaces feels like a practical way to keep teams aligned without losing the nuance of each idea.

Hey Product Hunt 👋

Quick update on a new feature I’m building next: Social Canvas 👀

While working on CommentCanvas, I realized creators often want to share or feature existing social posts—their own or others’—but the raw screenshots usually don’t look great. Cropping, resizing to 1:1, adding backgrounds… it’s all manual work again.

So instead of taking a post URL, Social Canvas starts from a screenshot of a social post. You upload the screenshot, and it automatically turns it into a clean, square (1:1) social-ready image with beautiful backgrounds and preset styles (gradients, glow, solid, transparent, etc.). No heavy editing controls—just fast, polished results.

The idea is simple:
turn messy screenshots into shareable, featured visuals, perfect for reposts, highlights, carousels, or inspiration posts.

It’s still tagged as Beta, but I’m excited about how useful this could be for creators and social media managers. Would love feedback on this direction or ideas for presets you’d want to see 🙌
