FAQ

About the post preview tool.

Which platforms are supported?+

Facebook, Instagram, TikTok, X (Twitter), YouTube, LinkedIn, Telegram, Pinterest, Threads, Reddit and TikTok Shop — each with desktop and mobile views.

Is the "see more" truncation accurate?+

We simulate each platform’s fold point using weighted character counts (CJK and emoji count double). Real platforms fold by line, so treat it as a close approximation.

Can I preview videos?+

Yes — upload a video and we show its first frame with a play button overlay, exactly how it looks in feeds and in exported PNGs.

Can I use a different caption per platform?+

Yes. Edit the caption for any single platform without touching your global draft, and restore it anytime.

Is my content uploaded to a server?+

No. Everything stays in your browser — media never leaves your device.

How do I publish the post for real?+

SocialEcho publishes the same content to all your channels in one click, with AI per-platform rewriting. The preview tool is the first step of that workflow.
