What is PlugThis?

PlugThis is an AI builder focused on Chrome extensions. Users describe what an extension should do, which websites it should run on, and what information it should remember. The tool generates a Manifest V3 package, including the manifest, popup interface, content scripts, and background service worker. Chat-based edits let users refine the extension without writing the code themselves.

The generated folder can be downloaded and loaded into Chrome, or prepared for publication in the Chrome Web Store. Users own the source code and can modify, share, or sell their extensions. For extensions that need accounts, databases, or server-side logic, PlugThis generates backend code connected to the user's Supabase account. AI features inside an extension use the user's own API key from providers such as OpenAI, Gemini, or Groq.

Subscriptions cover one or three extensions, with build and editing chats subject to a fair-use cap. Downloading and using completed extensions does not incur a separate PlugThis charge, and existing extensions remain usable after cancellation. Publishing requires a Chrome Developer account and a store listing; backend and AI functionality require the relevant external accounts.

What can PlugThis do?

  • Prompt-based extension building

    Describe an extension in plain English, then use chat to build and refine its behavior.

  • Manifest V3 code generation

    Generates the manifest, popup, content scripts, background worker, permissions, and extension packaging.

  • Supabase backend support

    Connect a Supabase account to add authentication, databases, and server-side logic to an extension.

  • Bring-your-own-key AI

    Use your own OpenAI, Gemini, or Groq API key to power AI features within generated extensions.

  • Downloadable source code

    Keep and modify the generated code, install it in Chrome, or publish and sell the extension.

Frequently asked questions

How much does PlugThis cost?

Starter costs $9.99 per month for one extension. Builder costs $29.99 per month for three extensions, full-stack support, and priority support.

Are build and editing chats unlimited?

Both plans include chats without a per-chat charge, subject to a monthly fair-use cap. PlugThis emails users before they approach that cap.

Can I sell or publish the extensions I build?

Yes. You own the generated code and can publish, sell, modify, or share it. Chrome Web Store publication requires a Chrome Developer account, which has a $5 one-time Google fee, and a store listing.

What happens if I cancel?

You can cancel through account settings. Extensions already downloaded remain on your machine and continue working after cancellation.

Do AI features require my own API key?

Yes. AI functionality inside generated extensions uses your own OpenAI, Gemini, or Groq API key, with provider usage billed separately rather than through PlugThis.

Is there a refund guarantee?

If the generated code does not work, you can email PlugThis within seven days for a full refund. You keep what you built.
