How it works

  1. Pick a tool from the directory below.
  2. Upload, paste, or type your input.
  3. Download or copy the result—browser tools keep media local; API helpers only send what you submit.

Use cases

  • Prep clips before a Flow Studio or timeline edit
  • Extract frames for thumbnails, storyboards, and AI reference sets
  • Build Kontext or LoRA training pairs without a local script
  • Check face consistency across AI-generated stills
  • Export notes and READMEs as a shareable PDF
  • Preview how a URL looks on phone, tablet, and desktop
  • Audit robots.txt, sitemap, and on-page SEO for early websites
  • Enhance prompts for Nano Banana, Seedance, Kling, Veo, and more
  • Generate a free AI shot list from a script or idea
  • Run a free AI persona panel when you want a few voices on a product or story idea
  • Copy ChatGPT, Claude, Codex, or Cursor agent skills (SKILL.md) for writing workflows

Most tools process files in your browser. Prompt enhancer, SEO audit, shot list generator, and persona panel chat call our API for the text you submit. Agent skills are static files you copy locally.
