ManifestGo

About ManifestGo

ManifestGo is an AI Chrome extension builder. Type what you want — a basic utility or a complex multi-feature extension — and our AI ships the entire build for you: manifest, popup, background script, content scripts, icons, and assets. Preview it live, iterate with natural-language follow-ups, and download a packaged .zip ready to load into Chrome.

What ManifestGo can build

  • Productivity tools (tab managers, bookmark organisers, todo overlays).
  • Content blockers and site customisers (ad-hiders, CSS injectors).
  • Page enhancers (summarisers, translators, dictionary lookups).
  • Developer utilities (JSON formatters, colour pickers, font inspectors).
  • Form fillers, scraping helpers, and data exporters.
  • Complex multi-surface extensions with popup, options page, background worker, content scripts, and context menus.

How to use it

  1. Sign in (email or Google).
  2. Type a prompt describing the extension you want.
  3. ManifestGo generates the full file tree — manifest.json, scripts, HTML, CSS, icons.
  4. Preview the popup live in the in-app sandbox.
  5. Iterate by sending follow-up messages ("add a dark mode", "track usage in storage", etc.).
  6. Download the .zip and load it into Chrome via chrome://extensions → "Load unpacked".

  • Manifest V3 by default.
  • Instant .zip download, ready for Chrome.
