Write titles & thumbnails

Click Write titles & thumbnails. In about a minute the agent writes, from your video's own script:

  • YouTube: a search-friendly title, a description with chapters (from the real scene times), and tags.
  • Instagram: a caption with a strong first line, and hashtags.
  • TikTok: a short caption and hashtags.
  • Three thumbnails: each a short, bold headline on a real frame of your video.

Everything is written in your video's language.

YouTube

  • Title: up to 100 characters. The counter warns past 70, because about 70 show in search results.
  • Description: up to 5,000 characters, including the chapters block (0:00 Intro…). YouTube needs at least three chapters of 10 seconds or more, so very short videos get none.
  • Tags: add with Enter or a comma, remove with ×. The counter shows YouTube's 500-character limit.
  • Copy title, Copy description and Copy tags copy each one to paste into YouTube.

Instagram and TikTok

  • Caption: up to 2,200 characters.
  • Hashtags: add or remove them like tags.
  • Copy caption with hashtags copies both together; Copy hashtags copies just the hashtags.
