Built with PlugThis
A SaaS founder built two Chrome extensions to extend his product with PlugThis.
Chetan Giridhar, founder of Indexly (an SEO and AI-search-visibility platform), set out to build Indexly Vault so his customers could gather their research across AI engines in one place. He started developing it himself, then stumbled on PlugThis in Google Search.
The extension was working in 2–3 prompts. He polished it with assets and submitted to the Chrome Web Store. Ready in a day. It was so easy, he went on to build Reddit Responder right after, to help his customers grow visibility in AI Search.
No engineering team. No weeks of dev time. Described, built, shipped.

Or, start with a template.
These aren't demos. They're working extensions you can use the moment you sign up, or tweak to fit your exact workflow.
Use them as-is. Or change anything. “Make the sidebar wider. Add dark mode. Export to CSV.” Just say it.

Built for Chrome.Not a clunky workaround.
Lovable, v0, and Bolt are incredible for web apps. Cursor is a powerful AI editor. But Chrome extensions have a completely different architecture. Here's how they compare.
* These tools can generate Chrome extension code if explicitly asked. The difference is PlugThis does it automatically from a plain English description — no extension architecture knowledge needed.

About PlugThis
The Chrome extension builder.
Built for the platform, not retrofitted onto it. Manifest v3, content scripts, background workers, and Chrome APIs — all generated from a single plain-English prompt.
01
What is a Chrome extension builder?
A Chrome extension builder generates the code, manifest, and packaging files needed to create a Chrome extension without writing any of it by hand. PlugThis is the only AI builder designed specifically for Chrome extensions, so it understands the platform's architecture instead of pasting in generic web app code that won't run inside Chrome.
02
How does PlugThis build with AI?
Describe your extension in plain English. PlugThis uses Gemini 3.1 Pro to generate the full Manifest v3 package — manifest.json with the right permissions, content scripts for the right URLs, a popup UI, a background service worker, and a Supabase backend if needed. From prompt to working extension takes under two minutes.
03
Can I build without coding?
Yes. You don't need to know JavaScript, the Chrome extension APIs, or the Manifest v3 spec. Describe what the extension should do, which sites it runs on, and what data it should remember. PlugThis handles permissions, file structure, message passing, and packaging — and you keep full ownership of the generated source.
04
What kind of extensions can I build?
Anything Chrome's extension APIs allow — page summarizers, focus-mode blockers, autofill tools, price trackers, AI writing assistants, meeting transcribers, tab managers, scrapers, translators. Every extension is Manifest v3 compliant and ready for the Chrome Web Store.
Chrome extension builder FAQ
Question 01
Can I really build a Chrome extension without coding?
Yes. PlugThis generates the full Chrome extension code from a plain-English description. No JavaScript, no manifest format, no Chrome API knowledge required. Most users have a working extension loaded in Chrome within five minutes of signing up.

Generate Question 02
Does PlugThis support Manifest v3?
Yes. Every extension PlugThis generates uses Manifest v3 — the current Chrome standard. Manifest v2 was deprecated in 2024 and extensions using it are no longer accepted in the Chrome Web Store. PlugThis output is fully compliant.

Question 03
Can I publish PlugThis extensions to the Chrome Web Store?
Yes. The output is a complete, packageable extension. Pay the one-time $5 Chrome developer fee, upload the zip, fill in store listing details, and submit for review. Most extensions are approved within a few days.

Question 04
What can a Chrome extension actually do?
Read and modify any webpage, inject UI elements into existing sites, communicate with external APIs, store data locally, intercept network requests, control tabs and bookmarks, send notifications, respond to keyboard shortcuts. PlugThis can wire up any of these from a plain-English description.

Question 05
How is PlugThis different from ChatGPT or Lovable for building extensions?
General AI tools and web app builders generate extension code in pieces and stitch them together inconsistently. You end up debugging missing manifest entries, wrong permission scopes, broken content script injection, or build paths that don't match Chrome's loader. PlugThis is built specifically for Chrome extensions — it knows the file structure Chrome expects, validates the manifest, packages everything correctly, and gives you a working unpacked folder on the first try.
