Why browser-local

Why this format works for a first tool site

  • Processing stays in the browser, so privacy is easy to explain and fast to trust.
  • Subtitle jobs are small, repeated, and task-driven. Search intent is clean.
  • Every tool can be paired with a short guide, which helps avoid thin pages.
