SeedViral

Free tool

Free caption writer for TikTok, Reels and Shorts

This writes the text that goes with your post (the caption or description), not the words on screen. Your facts stay exactly as you typed them.

Platform
Tone
Ask viewers to

This is the post text, not the on-screen captions (SeedViral videos already have those). Writes in English from what you type. It doesn't look anything up, so every fact comes from you.

Three versions of your post text appear here.

How it works

  1. Say what the video is about and add the facts you want in the post.
  2. Pick the platform, a tone and what you'd like viewers to do.
  3. Add keywords for hashtags, or leave them empty to use words from your topic.

Example: Reels post text about sleep

Let's talk about how much sleep adults need.

• Adults need 7 or more hours of sleep a night, according to the CDC.

Save this for later.

The facts are the example writer's own; the tool repeats yours exactly as typed.

FAQ

Questions

Is this the same as on-screen captions?
No. On-screen captions are the words shown while the video plays; SeedViral videos already include them. This tool writes the post text that sits under or beside the video.
How many hashtags does it add?
Up to five for TikTok and Reels, three for Shorts, made from the keywords you type (or from your topic).
Which languages?
English only.
