Fake comment generator: build a full comment thread as an image
With this free fake comment generator you build an entire comment thread – multiple comments, nested replies, likes, timestamps and verified badges – and export it as a realistic image. Unlike a single screenshot, a full thread shows a living conversation, which makes it feel far more credible in ad creatives, agency pitches and presentations. Everything runs right in your browser: free, no sign-up, and none of your inputs are saved.
Typical use cases for a realistic comment mockup:
- Social-proof visuals for ad creatives on Instagram, TikTok, YouTube & Facebook
- Agency pitches and concepts where you need to visualize engagement
- Before/after examples and training material around community management
- Content previews before a real post goes live
Need just a single comment instead of a whole thread? Use the comment generator. For a matching post mockup, try the Instagram post generator, and you’ll find every other tool in our tools overview.
How do I create a realistic comment thread?
First pick the platform (Instagram, TikTok, YouTube or Facebook) so the mockup automatically adopts the native layout – in dark mode if you like. Then add as many comments and replies as you want and set the username, avatar, likes, timestamp and the blue verified checkmark per entry. The preview updates live; when you’re done, download the thread as a PNG. Mockups are meant as a design and visualization aid for concepts and ads – don’t recreate real people or brands without permission and don’t present them as genuine screenshots.
In real life, a thread this lively comes from actively replying. That’s exactly what replient.ai handles for your comment management: comments are answered automatically in your brand voice or hidden – more on that with Instagram comments powered by AI. That’s how a staged mockup turns into real engagement.
