Free tools for short videos. Twenty-five of them, free.

Twenty-five small tools for the questions every short video and every new account brings: how long is the script, can the subtitles be read, will the file pass, will the buttons cover the text, how many phones. Every rule links to its source.

  • Sourced. Platform limits read on 28 Oct 2026, each linked under its tool.
  • Private. Files and text are read in this tab; nothing is sent to us. One exception, said on its page: the short video analyzer.
  • Free. No account, no limit on use — the analyzer gives one free analysis per account.

These check one thing. The studio runs the network.

Vertiscale finds what to post, makes a different video for every account, publishes it through the official APIs and learns from what wins. Publishing is in beta; TikTok posts stay private until our app passes TikTok's review.
